Reliable helpe
I like the app and being able to set up an auto clean. The suction and mopping is good for a regular clean. The battery life could be better and it does get confused sometimes but generally I’m very pleased with its performance.
Laresar robot hoove
Love it! So convenient. Not too noisey. Was easy to set up the map for navigation.
Appearance is also good- isn’t in the way, can fit into the corner. No problems with battery life- it completes my downstairs rooms in 1 hour without any problems. Have recommended this to many people
Laresar L6 NEX Robot Vacuum Cleaner with Mop
I’ve had this Robot Vacuum Cleaner for almost 2 months and have to say I’m more than pleased, its ease of use amazing suction and all round functionality, would definitely recommend.
Does the Job well and I have four dogs
I was cynical about robot cleaners, never believed they were any good on carpets only tiled floors, especially having four dogs. But I was wrong the L6 Nex cleans very well and has no problem with
the amount of dog hair my dogs produce. No doubt the best labour saving device I have ever bought.

Great Vacuum
Love how easy it was to set up and how effective it is.
Mapped out our house quickly.
Gets over our 2 large door thresholds easily.
Picks up dropped pet food (pellets) easily.
I have it set to eco once a day with a “strong” deep clean once a week.
It is a bit noisy depending on the strength of suction setting, but worth it for a clean floor.
Gets into the corners and underneath our furniture easily.
Love that it self charges and self empties.
It did have a blockage the first time it self emptied, but it had found a lot of hair under furniture that I don’t normally reach, and this was easily fixed by just pulling the clog out of the base unit (clear channel at the bottom so easy to spot and clear the issue). Haven’t had that issue since then.
Haven’t tried mopping yet, but I will soon.
Very happy with this vacuum.
She's lovely
Vera has been in our house for a week now and she’s working amazingly well. It’s super dusty where we live but I’m finding a significant reduction on the dust settle around our home. We mostly use the vaccum and not mop function. The self clean is powerful and frankly even with daily use we haven’t had to empty it yet. I love her chatty information too.
This works if it can clean my house then it works
We have 2 St Bernard dogs lots of fur lots of mud and dust, uneven floors as it is a old house and it cops better than a normal vacuum we run this 4 times in a 24hr day it dose get jammed up with fur just once a day that’s because we have a excessive amount, it also finds the hidden socks and other items that randomly disappear by the act of dogs and kids running as free range to the elements of the wild. It really dose what it says on the ti
Reliability
We recently bought a puppy and just had to get a vacuum of some sort. Having researched various types Laresar Robot Vacuum Cleaner seemed to be on top of all other brands and at a reasonable price. I was surprised and pretty entertained how it mapped the area then done its business navigating across our wooden floor, mounting rugs etc, watching how it created its own grid, i was amazed at the technology that must have gone into such a smart device. As yet I have not used the mop therefore cannot comment!
App! still i have yet to try again to figure it out and would say that despite sending an email to Lasesar (no reply), I little bit more tech support wouldn’t go amiss.
For quality and design, It cannot be faulted its 100%, for tech support(to date I would give the support 10%)
Love it !
Easy to set up, Does a good job.
I have a large downstairs area, and have 3 cats and a dog that molt a lot. It took care of all areas that were open, automatically mapped areas it could do. Went over thresholds and rugs with ease.
It did struggle to empty into base one it’s first run, but it was chock a block. Subsequent uses have been fine. Overall I’m very impressed, She has become part of the family. Also impressed with the after sales care.
Amazing!
I never write reviews but I am so impressed with this little guy.
We are a house with two dogs, two kids and a cat and Tina the cleaner as we call her has simply made cleaning a breeze. I set her off every evening and the floors are hoovered, mopped and left sparkling clean. She has mapped the whole of the house and o can select a room or just open the doors to the room I want cleaned and off she goes.
My only worry is getting hold of replacement filters etc
Really good to send round every couple of days
Took us a bit of time to set up the maps as found the instructions a bit short, but once we worked it out, we managed to get maps for two floors sorted easily. Was also a bit confused with when it would mop but I asked the question to support and they were helpful in their response. It now runs around every couple of days and does a good job. I tend to use it when I am around as have a cat who is sick occasionally so I want to make sure the floor is clear(!) before setting it off! I very rarely have to intervene with it and when I do, it is because of me not clearing something out the way properly. Would recommend, though not sure if I would worry about the mopping again as it is more of a damp dust. Definitely made my life easier!
Impressive little machine.
This is the 2nd L6 Nex I have had as the 1st one had to be returned as there was a technical fault with it, but customer services were great (although the replies took a bit longer I’m assuming due to the time difference) and I now have the replacement. I chose this brand as the other reviews stated that it was best for pet hair, which is definitely a priority in my house. At first I was a little disappointed that it was not self-emptying as it kept clogging and so needed emptying and untangling manually, but now as I use it daily, it seems to cope and now empties at the end of its cycle. My husband commented that it was quite noisy, but compared to my actual hoovers, I disagree. Being able to choose which room you want the robot to go to is very handy and then to relocate itself is impressive. The only reason I have not given 5* is because I have not yet used the mopping function, so can’t comment on the overall performance, but going on how it operates now, I would definitely recommend this product.
Handy little helpe
Bought this as my illness means I struggle to vacum. It does a great job at vacuuming. I’ve not tried mop as you cannot use detergent with it (this needs to be in product info on amazon sales page)
I cannot get app to work as useless with tech and it cannot use my normal Internet speed…
I had problems as vacum itself got blocked and it kept telling me it was Dock. I followed instructions and Dock clean. I contacted company via email and swift to answer but didn’t seem to understand the robot was clogged. In the end I removed brush and managed to unclog from there.
They need instructions in pamphlet on how to do this.
Also a button so you can decide to empty robot after each use, if you want to, would also be useful.
If these 3 things were included (and easier connection to phone) I’d give it 5 stars.
As it is, it has been very useful and meant I do not need help of a cleaner.
Great smart robot vacuum
Used this to replace a several year old ‘dumb’ robot vacuum that constantly go stuck everywhere and took forever. This has nearly triple the suction power than that basic model, plus all the other features such as a 2 month auto dust box to clean out the robo on docking. The mop was another reason I purchased as I have a mix of hard floor and carpet. I have noticed that the mop pad stays wet the moment you fill it, which ‘may’ become an issue after a few sessions (mildew smell perhaps?) but it hasn’t caused any issues so far over the last week or so. I have set to mop a small bathroom with medium water amount, and a double clean max water for a large kitchen which seems to use most of the reservoir. I spent quite some time sending the robo around my floors to get a decent lidar mapped floorplan, and must admit the app isn’t entirely obvious what you must do (not many instructions). It was a bit of trial and error but think I’ve got it finally, one mistake was when I put robo on another floor it seemed to be quite confused, so I deleted the floor to give it a new mapping, losing all my hard work configuring the previous oen (and another couple hours of fiddling needed)! I worked out how to order the rooms so the mopping feature can be the last rooms in order (it vacuums and mops at the same time), little tips, send it out without water in on first use as it puts mopping on for every room when mapped/discovered, before you’ve edited and ordered (however carpet didnt seem to feel wet, but you can def see a snail trail on hard floor!). Also, when you set a schedule (Timer), tell it to use Designated Room Cleaning not House Cleaning or it won’t follow your per room instructions if you have them. Overall, I’ve barely had to rescue him, everything is looking nice and clean, the advancement of having lidar navigation per room mapping is groundbreaking. Happy purchase!
Real time save
I have been using my Lareser vacuum robot now for 2 weeks. Purchased this as a Christmas present for our family. We are quite happy with our purchase. First time when we used it, it was on the ground floor. It moved around the floor and created a map. The APP allows you to save the map and name the rooms. The APP allows you to then sweep the specific rooms. It was a bit tricky to figure out how to use it on the first floor, but we eventually figured out. The only downside using on mulitple floors we found was that we need to move the docking station as well as the sweeper. First time we vacuumed our carpet floor, it had a lot of dust. The dust got accumulated in the vacuum. The automated cleaning routine was not able to clear by itself as some carpet dust got accumulated inside and created a lump. We were able to pull it out using our fingers and everything was ok. Hairs can get entangled in the rotating brush, which need to be taken out manually. This is the case with any vacuum cleaner. Once our sweeper was entanged in electric wires, but it was our fault that we forgot to remove wires from one particular corner.
So, in summary. Once we have learnt how to use it, just clear the floor. Remove all obstacles and wires and set the robot to vacuum. It will go around in all your set rooms and do the vacuum. It has proved to be a real time saver for me as it was my job to do the vacuum in my household.
Good value for the price
Pros:
1 – Keeps the floors relatively tidy – we have a cat and hair, litter and dust gets everywhere.
2 – The mop function is good though it’s water only
3 – Ability to configure different suction and water levels for different rooms and areas – great for high suction and and mopping function for kitchen vs configuring a non-mop area for carpeted sections.
4 – The app is easy to use and quite configurable with timers, room mapping, room splits and merges etc
5 – Smart problem solving tech – it takes its time but the tech used to determine location and obstacles is pretty good.
Cons:
1 – Quite loud – both my husband and the cat hate it lol
2 – The mop function is water only so we end up spraying a floor disinfectant before the robo vacc gets there
3 – There are only a couple of things that trip it’s sensing configs in terms of obstacles (a) low hanging wires may catch it around the protruding head (b) i have an L-shape table that slides under the sofa, but if it’s not under the sofa, the vaccum gets stuck between it’s legs on the floor.
The best thing I have ever bough
I did quite a bit of research before deciding on the Laresar Nex 6 and I am so glad I did. Looking at some reviews and comparison sites it has some functionality that is usually found on much more expensive models such as intuitively mapping your rooms, navigating obstacles exceptionally well, self-emptying and allowing for the programming of no go zones without the need to use magnetic strips on your floors. The app is a little clunky but once you explore it and work it out you can customise how your rooms are cleaned, setting the water outlet closed for carpet (no mopping) and setting suction levels. I have 2 kids and 3 pets and a busy job so this is a game-changer for me. The product comes with a 2 year warranty and support. The only limitations really are you need to be careful of any cables it can get tangled in and for the best results, clear any clutter out of its way though it will just work around it otherwise. You can set no go zones on your map for pet bowls etc to avoid any mishaps. Be sure to save your map after the first run, then you can add to it with any such requirements. As it needs the station to navigate from I’ve not taken it upstairs, but if you want to use it on different levels, bear in mind you will need to take the charger station too. As my daughters and I have long hair I need to keep an eye on the roller and clean it every few runs but that’s a 2 second job with a tool Laresar provides and the least I can do my faithful helper. Love it!
The best robot vacuum we’ve ever had!
This is our third robot vacuum now but this one absolutely knocks the others out the park! It’s so intelligent creating perfect maps of your home so it knows where everything is and goes around furniture. You can see the legs for the dining table and chairs perfectly mapped out.
It hoovers and mops simultaneously and does a great job with each. In the month since we’ve owned this I haven’t had the main hoover out once! And that’s with 2 cats in the home. Handle corners and pet hair with ease.
Very noisy when emptying itself but it’s very short lived and you can set it not to do it automatically if you have babies asleep etc. The charging station holds a lot also as in a month I still haven’t had to change the bag and again we have 2 cats moulting for the hoover to deal with.
Spot clean is the best thing ever! Especially with kids. You literally click on the map and tell it where to go. So for example we use it after meals and tell the vacuum to just go round the table and get what the kids have dropped.
One minor annoyance is that if you want it to more than one floor. So downstairs and upstairs you have to carry the vacuum and the charging station up as otherwise the vacuum can’t locate itself. As the charging station is heavy and bulky it’s not convenient but as I said minor annoyance and doesn’t take away from how much time this vacuum has given me back.
Syncs with Alexa seamlessly so can be used as part of routines or voice commands which is very useful as can program it to vacuum overnight and always wake up to clean floors.
Finally another useful feature is the restricted zone. You can see on my map I have a red line where the Christmas tree is and you simply mark any areas you don’t want the vacuum to go and it avoids them completely. In all, highly recommend this vacuum.
Great vacuum, easy to set up - would highly recommend
This product is amazing, easy to set up and it cleans really well. We have 2 long haired cats and it really cleans up the fluff. We have set daily cleaning areas in the high traffic areas and it comes out at set time cleaning carpets, tiled floors and laminated. We still have the mop to set up, as only got for Christmas. We used the spot clean using the pin after dropping cereal and after picking up the mains slip out came the vacuum and sorted out the floor all spotlessly cleaned. Love it so much thinking of getting a second one! Would highly recommend.
Amazing Cleane
We purchased this cleaner just before Christmas 2023. We bought it on the recommendation of our Daughter and Son in Law who had purchased the same make and model a couple of months earlier. They absolutely loved it. Can honestly say we do too, a definite game changer for us. Being in our 60’s anything that makes our lives easier is a plus. Very easy to set up and does an amazing clean. Very clever technology, almost a human but in a machine! We’ve named ours “Colin” after the name my Granddaughter gave hers! Love how “Colin” can map out our rooms, clean when we requested what rooms needed doing, can go back to his base on his own when his battery is getting low or he needs to recharge. My Dyson days are over after more than 30 years of pushing, emptying and moving plug sockets when lead doesn’t reach all the rooms! Lovely having very clean laminate flooring, carpets and tiles, Colin is now a hero in our house.
The vacuum is one of the best in my opinion at this price point, it will scan, map, path, vacuum, mop, empty & more!
All you need is do is find a suitable location for the base, run the auto cycle and for me it took a few hours to setup the room split, different suction & water levels & the auto timer function. Once its all setup within the app you just need to check the room doesn’t have certain items that will get in the way which you overlooked (for example a Christmas tree skirt, its too low for the sensor to pickup and also too light/small for the bumper to not be triggered). Once the area is mapped out and virtual walls or restricted areas are setup you’re good to go. There is not much human input required aside from topping up the water in the base ever week or so depending on mopping frequency.
Overall I would say its great value for money and as the title suggests we are saving around 1 hour a week (10 mins a day) in our house, which is over 1 work week every year or an extra hour every weekend!
It would be nice to have the more expensive hoovers that can auto refill and empty the water but they are around 2.5x the price and the additional time saving with those in relation to how much extra you are paying isn’t worth it. You may get an extra 5 mins every week because you don’t need to refill the water tank, though that is barely around 4 hrs saved/year for an additional cost of 600-800 – not worth it! This one does the job!
If you have carpets this may not be the best for you as the mopping function is wasted and you would be better off getting a higher suction power.
Overall I am VERY happy with this purchase and honestly the only downside is I wish I brought it sooner!
Rob (the robot) is currently doing its job whist I’m working mine!
We have been very impressed with this. It’s easy to set up, mapping the rooms out well. We have set up two different maps, one for upstairs and one for downstairs. Very happy with how well it works. Suction is good, mopping is ok for a regular wipe over, but it doesn’t match a mop and bucket!
Great robot vaccum cleaner!!! Highly impressed!
This is my first robo vac, and I have to say – I’m very impressed!
Linking to Google Home was fun, but I managed to do it! I’m still playing around so don’t know all the voice commands yet, but in Google Home, add device “Works with Google”, then search for “Smart Life” (blue icon, with an outline of a white house – see image)
“Hey Google, turn on L6 Nex”
“Hey Google, turn off L6 Nex” or “Hey Google, finish L6 Nex”
For what seems a good list of commands, Google “How to control your robot vacuum with Google Assistant” (on The Verge).
…although its to be noted that the docking/return to base I can’t figure out yet?!
Overall this thing is incredible. I was clearing the floor thinking it will do a room, and wanted to set up the dining room first, and it just wondered off into the hallway and lounge itself too to map those areas too. Once the mapping process was done, it started cleaning the carpets and hard wood flooring while creating a hoovering pattern. I happen to have a thick rug in the lounge and it did struggle maneuvering over the thick rug – especially the edges, so I’ve had to exclude that area from the robot. It did also struggle to suck up some stickers that were on the carpet due to the 3 year old grand daughter! However I later realised the suction was on “standard” and could of been set to “strong”. A part from the few stickers left on the carpets, the rest of the downstairs carpets and hard wood floors looks clean!
Where its positioned, isn’t ideal but the best I can do for now… so I’m unable to use the timer feature, but that is an awesome feature to have so it can easily be set to come on everyday at a certain time, or any combination of days i.e. twice a week or once a week – at a time convenient with yourself, so you could set it running while everyone is in bed or during the day when everyone is at work!
The dust collection is brilliant… I haven’t checked how much dust in currently in there as only had it a few days, but I’ve seen others on Youtube that need emptying daily as they only have small collection bins on the hoover itself and no larger bin for collection.
A part from linking it to Google, everything else was pretty much straight forward.
The smart app (Laresmart App) is a little tricky – as you can have the robot unassigned to a room and shown under “All Devices”, or linked to a single room. If the robot is doing multiple rooms (like mine where its doing the complete downstairs), you can’t assign that to every downstairs room in the app.
I’m not sure if you need to clear your floor for the initial “mapping”, but I have seen some YT videos that state that was best practice. So if you have an obstacles in the way, best to move them out the way for the initially mapping process! I’m only talking clutter, not chairs/sofas or stuff that wont move anyway!
Having a 3 year old grand daughter living with me, I was fed up getting the hoover out to clean up crumbs when she sits and other mess she creates, so this will hopefully make my days easier! Time will tell!
Initially before receiving it, I wondered if I had just wasted my money on a “gimmick”… but after using it and seeing what it does, I feel it’s worth biting the bullet for – especially while its in a sale!
[UPDATE] So I had been struggling with my room mapping as while looking at all the settings/features in the mobile app – I had accidentally deleted my first initial good “map”. While trying to do a new map, it would only mark the edges, and I just assumed this was a quick thing as it somehow referenced its now deleted map data. I got it to hoover, and it only hoovered the edges. Perplexed, I deleted the map again and re-configured it and made a new third map – this was also edge only… hmmmm….. So while I was playing around in the settings (Map diagram -> Settings -> Cleaning Mode) I remembered there was an option for:
“Quick Clean (Edge / Zig Zag)”
“Y-Shaped Cleaning (Mopping)”
“Edge Clean”
I had accidentally knocked it onto “Edge Clean” so it wasn’t doing the full room. Once I changed it back to “Quick Clean (Edge / Zig Zag)” – the new map was perfect again!!!
Recently changed our dining room to a laminate floor to help with cleaning having three cats. To assist in keeping it clean I decided to buy this Robot Vacuum Cleaner. My wife was sceptical and thought it would just be another expensive gimmick.
It arrived quickly, was well-packed and easy to set up. Downloaded the app for my phone, set it up without issue and set the robot to work. Its initial run is an environment discovery which maps the rooms it can get to. By chance all doors were open and it left the laminate room and switched to the carpeted room without issue. This resulted in a good clean on both the laminate and carpet. Once it has completed its work it returns home, empties its bin into the docking station and recharges. It now has a map of the work environment and is available on the app for further customization.
The app is not very intuitive but with a bit of trial and error, you soon get the hang of it. The robot and app only work on 2G and not on 5G WifI. It would also be good if the app could communicate with the robot outside the house so you could command it to do an ad-hoc clean when required but this does not appear possible. However, it does appear that it will work with Alexa and Google Assistant, which I have not yet tried.
At present, it’s configured to work every morning on a timed run at 6 am before we get up. Be warned of a potential major issue here. As it was working before we got up, the room was never checked — BAD IDEA. A cat had been sick and the vac decided it would do its best to clean it up — REALLY BAD IDEA! What a mess, took a while to de-sick the vac and resume normal operation. Advice, check before you leave it to work!
Issues — the app is a little tricky as mentioned and replacement supplies seem to be hard to find with limited availability. It requires some new mop pads but they are currently out of stock and other robot pads are not compatible.
In summary, works surprisingly well and is certainly not a gimmick. I would certainly buy another, does a good job cleaning and mopping. My wife also mentions that the floors have never been so clean, being cleaned and mopped every day LOL!!
I’ve been using this robot vacuum for about two weeks now which I believe is enough time to leave a fair and thorough review.
In summary for those short of time – this thing is genuinely brilliant. I have found the app to be excellent and the cleaning performance superb. Almost every time I leave the house I set it away via the app and come back to lovely clean lines in the carpet and nothing left behind.
The app is intuitive and has lots of features and settings I didnt even think I’d need or want, such as being able to set specific suction / water levels per Individual rooms / assigning no go areas or the ability to spot clean just one room if needed. It shows battery level, time cleaning and area cleaned which is a nice touch. Haven’t used any Alexa commands yet as it’s just as easy using the app
Cleaning performance – I’m aware it won’t be as deep cleaning as my Dyson V10, but for day to day maintenance it is spot on. Picks up all amounts of crumbs, hair and general mess that our cocker spaniel and cat leave behind. We even found a 10p coin in the dust bin last time I checked, never would I have though it would be strong enough to pick that up! Looking in the docking station bag it seems to be really picking up all the fine hairs from our pets so totally chiffed with that. The mopping is also good, it doesn’t just drag it around, it moves in a Y shape back and forward which seems to clean a bit better. With it only using water it’s never going to be the best mop ever but it’s good enough. I just had to make sure on my app I set it to clean the carpets first – before the mop was wet, then move on to the hard floors
The docking station is also excellent. Nice and compact and seems very well built. Unobtrusive against the wall and serves a good purpose. When the robot is docked and emptying in to the dock it sounds like it’s about to take off, but I guess it needs to be Powerful to make sure the robot is totally empty and free from any blockages.
Manoeuvrability – thought I was going to have to make a small ramp as the kitchen and living room have about 1″ height difference but this just climbs it with ease. Never once has it got stuck in the kitchen and always just climbs back out which I am very impressed about. It has only once gotten stuck on the top of the stairs, the app claimed one wheel was stuck and it needed help moving off, but when I checked it was totally fine. It’s only happened once so guess it was just an anomaly.
Things to improve – in short not a lot. It would be great if their next model had the ability to lift up the mop from behind and refill itself from the dock so you don’t have to keep tending to it everytime you wanted to mop the floors. But there is already a robot on the market that does that, but it is 3x the price.
Overall I am very satisfied with this robot and would definitely recommend. Im debating recording a video for YouTube in a few weeks for a more in depth review but for now I’ve uploaded a video of it collecting tons of spaniel hair just after we clipped her, all of which it done with ease
Very happy with my purchase.
I was very sceptical about buying this make of robot cleaner because I had never heard of it before. I also wanted their latest model, the N6 Nex which was released in March of this year (2023) and was concerned about spares parts and consumables. However the manufacturer lists all the consumables on Amazon so that’s when I decided to go ahead and purchased the robot.
Compared to my Neato (I have four D7’s) and my Dyson Eye this little robot is just as good if not better in many respects. It’s significantly quieter compared to my exiting robots and it’s the only one that self empties. I really like the fact it has two side brushes that work together which gives better cleaning results compared to single side brush robots. On this robot the dirt and debris is directed into the cleaning path of the robot and not flicked halfway across the room.
Having three dogs, two border collies and a Staffordshire bull terrier as well as a short haired cat I was concerned that it wouldn’t be able to cope with all the different animal hair. I only had one experience where it failed to empty the onboard dust box into the self emptying bin. All the pet hair had clumped together and it caused a blockage within the onboard dust container. I simply emptied the onboard dust container by hand and the problem was resolved. However to try and prevent this from happening in the future I now set the robot to clean all of downstairs every day, paying special attention to the lounge that has carpet, which it’s cleans twice as a customised setting I’ve created on the app. Instead of cleaning just the edges and once by going up and down, it now goes crossways, in other words it goes up and down and then left and right for a more thorough clean. See the attached photo that demonstrates what I mean.
I like the fact the app will allow you to name the rooms, customise the number of times it cleans a specific room/s, avoid certain areas as well as the order of the rooms to clean. The app also allows you to pick a specific start point to clean as well as a specific area to clean which is really handy if you’ve dropped a few crumbs on the floor.
I haven’t used the mop function as I already have the iRobot M6 which does that job quite admirably.
Overall the size of the robot is slightly smaller than others on the market but this is a good thing because it allows it to get around chair and table legs without getting stuck or more importantly missing sections of the floor because it can’t gain access.
The battery so far has lasted for the full duration of the downstairs clean. When it returns to the base after it’s finished cleaning the remaining battery life is about 16%.
One further observation is it’s the only robot vacuum, to my knowledge, that sucks the contents from the robots onboard dust container for a solid 20 seconds. When I compared this setting to other manufacturers I found they only sucked the contents of their robots onboard dust container for 10 seconds or less. This in my opinion makes a big difference especially if you have pets like us and means the onboard dust container on the robot is actually emptied.
