Absolutely brilliant cord less Hoover, does everything. It’s light weight, easy to use. Hardly any noise and sucks everything up.(dog hairs) Battery power is great and I have done up/down stairs on one battery. Quick charge.
Very Easy to store with the wall bracket provided and also easy to empty the dirt.
Value for money would recommend.
Overall the first impression
was the sturdiness and appearance of the Vax
(1st impression is important) and it was easy to assemble. It’s so easy to use with excellent power to clean any sort of flooring. I have recommended it to a friend who has decided to buy one.
Good suction, cleans well and deals effectively with pet hair which was an essential requirement in a 2 dog household. Works well on carpet and hard floors but use the correct setting. The extra power button is very useful on carpet but does drain the battery. However I can clean the whole house on one battery charge.
I do find it heavy but manageable. My husband likes the weight of it and has no issues.
Overall a good model which does the job well.
This is my first use of a battery-powered & first use of bag-less vacuum cleaner. Very happy to get away from dealing with mains leads & hoses & bags. I get on with the vacuuming now, rather than putting it off.
Needs emptying very often, but not really a problem when I have a system going. Having 2 batteries means I can use one battery all the way, and have another ready to swap in.
Slight problem with getting something to come apart at first. I managed to work out what had jammed, unjammed it, and now works fine.
There was a button missing from the hose-type-thing. I phoned up and they sent me a whole new hose, and they did not want the original one back.
So much better than other cordless vacuum cleaners we have owned (and not the ridiculous price of some other brands). Bought with 2 batteries (and charger) which are long lasting. The location of the powered brush bar button right next to the power button makes it annoyingly easy to turn off both together but otherwise this cleaner works. There seems to be a bit of flex between the cleaner unit and the long tube so will have to see if that becomes a problem. So as we haven’t owned that long its 4 stars for now.
I bought the Hoover as needed something else that was quicker and better so I was over the moon when I received it and it picks up so well and I can do the house in one go so I’m definitely enjoying the new lighter weight and turbo is actually so strong I can see the carpets moving very good product best Hoover iv ever bought and I have had the Dyson range and I can honestly say that the vax is so much lighter and better than having to plug it in and then it is a room at a time so I just charge it up put it on and I have done the whole house within 20 mins very good
Great portable for a two bedroom cottage. With rotating bar / power at max you get about 15mins which is enough to complete this amount of space. Easy to empty and clean. Happy with my first cordless vax.
Bought this for 135 from the Amazon Warehouse having bought a 70 pretender a couple of months ago based on ‘bogus’ amazing reviews on Google..ignore those (I gave it a pretty poor review).. basically if you want something decent buy a brand…this Vax blade 4 pet is faultless ..can’t afford it full price? Wait…get one from the warehouse half price. Said major external scratches blah blah…who cares? As it turned out it was perfect! Didn’t arrive in the Vax box, was minus the “construction instructions”..trust me, putting the thing together without the instructions was about as complicated as a 4 piece jigsaw puzzle. Do I love it and rate it? Oh yes! Before my 70 conned by bogus reviews buy, I had a Shark pet cordless..I rated that as great compared to the 70 bogus buy..well I would, it was like chalk and cheese! Compare the Shark to the Vax Blade 4 pet..the Vax blade 4 pet is far superior to my Shark..if you can get it for 135 like I did absolutely go for it.
It’s lightweight not like the hoover in the cupboard. It can stay there. The compartment looks easy enough to empty the Debree out of. Accessories are adequate and the performance is adequate as for the battery. The computer says now not impressed with the battery. Don’t think it’s 45 minutes somehow and at 60 for replacement battery I say no more. It comes with a fixing bracket some screws to hold the Hoover right onto the wall, I mounted a bit of wood and painted it and screwed it into the wall. It’s Andy just a job for me. I would give it 7 out of 10. The charging indicator on the top of the battery, the charger is a Plastic slides over the top of the battery
I like the way this product stays active once the ‘on’ button is pressed – I don’t have to keep pressing like on some other brands – I find everything good – no complaints
I love this hoover ! It’s light ,and it has two other settings which are for tougher jobs , the tools for the stairs and furniture which are good , for dog hair . Love it .
This is a very good vacuum and would have had 5 stars except for the battery I have a one bed flat yet struggle to vacuum it as battery seems to run out in less than 10 minutes.
The product is great but the delivery driver just dumped the parcel outside our front door without knocking, luckily for us we heard him. We have no front garden and this was a late evening delivery so we were not impressed.
I am very impressed with this cleaner, a little heavy for me, but that is due to my age. I used attachments for the stairs, which also look a lot better. The battery life is excellent and it recharges very quickly. I highly recommend the Vax Pet cordless vacuum.
So far we have been delighted with the ease of use and, more importantly, the ease of emptying the contents without re-spreading the crap all over the house again! You can detach the waste cylinder from the rest of the unit with a single click and the spring-door opens on cue once you’re over the bin (and press the button, of course).
Changing heads for some of the accessories is straightforward and the whole thing feels light and balanced in the hand.
Suction is fine for light stuff on the lightest setting but we tend to stick to the medium setting on carpets and save the ‘all guns blazing’ setting for more stubborn areas. Battery life is good enough to wiz round our 3 bed semi (with extension) on medium setting with the odd burst of full power.
It has great suction and power! It’s really light and switches to carpet mode to get carpets spotless! It’s got a good range of movement on the head and comes with a bracket to store it on your wall which is really convenient!
My Bosch Athlet Pet was very good (but not as good as a Vax, the suction paled in comparison) and the Henry I would have willingly strangled with its own cord!! My beloved Vax arrived this morning and my rug, which had been in storage for nearly 3 years, is all clean and lovely again after charging one of the 2 the batteries. Still lots of charge left! OK, this is a cordless, and a different shape, but it’s cleaning power is easily as good as my original corded Vax which survived a lot of years of hard labour. The dust collector is easy to empty (like all bagless hoovers, you do need to pull hair out) . Its easy to put together, the dog who nearly dies when a hoover comes out isn’t overly worried by this model – she will stay in the room. Now, where are the Vax carpet shampooers? I’ve worn that out after13 years of own use and lending to friends …..
Good suction and easy to handle. If you have it on full power it does not seem to have a long battery life. Changing the dust bowl and removing the battery very simple. Our last cleaner is still going after 30 years. Not so sure about this one.
This is a nice cordless hover
Very powerful on carpets if the boost button is pressed. Also very good on hard flooring. I put my old hover that is a Henry over the bedrooms the day before this arrived… I used this hover as soon as it arrived.. I was shocked at what it picked up.. Considering the carpets were hoovered the day before. I would definitely recommend this vax. One happy customer here.
Brought this as a temporary replacement Iam now using as my permanent vacuum cleaner I can do my entire house 5 times on 1 charge the vac is lightweight and easy to use plus you get a 3yr warrenty once you register via vax official website. The suction rivals that of my previous upright corded vacuum cleaner the cylinder is a joy to clean no nonsense.
Completed form online for to register but it wants a photo of receipt I now have to use laptop to print a receipt and then use tablet to take picture ,then upload to vax a pain so have not bothered. Also a prize should be given for serial number in very small text and a super long number gigantic etc Iam 64 years and do have computer literacy of a 25 year old who would have studied computer science at school. END OF STORY
Legacy have since registered successfully
I would recommend.
it against to the floor so not sturdy but good suction even the suction is not what it was when I bought my first vax but still better than some of the more famous brands I have had them all but return always to vax best of a bad lot. As we are not in Europe any longer maybe we will get stronger suction’s back in our hoovers
Compared to some handheld cordless vacs though it is really quite chunky and on the heavy side. I don’t find it unmanoeuvrable but after 15 to 20 minutes of use my arm is starting to seriously ache. That’s OK for us because we’re the kind of house to only do a room at a time.
If you’re someone whose vac routine is to do a whole house in one go, you’ll need to have some decent upper body strength, and you’ll probably need more than one battery because on the higher suction settings (and lets face it, they’re the only settings these battery powered vacs are any good on) you’re running out of power within 20 minutes. Charge times aren’t excessive – a few hours will see it back to full.
You’ll also need to have emptied the dust chamber out frequently on big vac jobs as it’s not exactly roomy. And how fast this thing fills up with dust gives a good indication of this vac’s ability to hunt down dirt. It’s a thorough little machine!
If someone in the house has long hair – especially hair with curls – expect the vac’s cylinder brush in the pickup head to choke up with hair strands within days. It’s easy enough to remove the brush and cut off the hair with a knife every now and then, but it’s a layer of nuisance that isn’t there with the Dyson.
You’re wondering if this is good for hoovering up the massive house spiders aren’t you? Look no further, this thing is an absolute beast, set it to the higher suction mode and it will instantly suck up any size spider you point it at.
It’s brilliant for other hoovering too but let’s be honest you just want it for spiders. 😉
Best hoover and I was prof cleaner for 15 years. Especially power head I love my little friend thank you
It makes me happy
Be careful on laminate floor as it can damage the laminate
Only just received but it has already rejuvenated the carpet. Excellent suction, I didn’t realise how bad my old vacuum had become.
This is a great hover you will not be disappointed
For the price the vac CLSV-B4KS cordless vacuum cleaner is a little beauty it has good suction battery is easy to charge nice and portable can even get right under the bed and wow the dust it can find under there no need to move bed result
Would definitely recommend this vax
Has much better suction than previous dyson and has more than enough battery to do my whole house. Not the lightest but not too heavy and still easy to use.
This is the best rechargeable vacuumed we have had.easy to use throughout the house on carpets and hard floors. The only small down is that my wife finds it quite top heavy, this is a small fault on a great machine.
The Vax cordless PWR Blade 4 is fantastic! I was a little reluctant to purchase a battery operated vacuum cleaner, thinking that it couldn’t possibly have the same suction power as an electric one to the contrary! It’s incredible how much dust this vacuum can tackle! It’s light and very easy to assemble and disassemble, in order to clean. I love the the light feature when you use the roller brush, which enables you to see beneath furniture, such as a bed or a sofa. All in all, I highly recommend it, however, I would recommend purchasing another battery for a bigger property – let’s say a three bedroom – as the battery runs out fairly quickly, most certainly if higher power is necessary for deeper cleaning.
The machine definitely does what it claims, which is to vacuum up dirt from the floor and from carpets. It has enough controls to ensure a good performance on both smooth floors and carpets. It’s quite powerful and the battery lasts very well in our typical pattern of use (a one-storey flat). It comes with a clip arrangement that one can attach inside a cupboard, so storing the machine is efficient.
It was heavier than I expected, and the dirt container is quite small so needs emptying quite frequently. The emptying is a bit fiddly, and I managed to drop the dirt container when I started using it, but one gets used to it. It is hard to say how long the rigid plastic of the container will last – just don’t drop it on a hard floor! When you want to stop using it for a short time, for example to move furniture, you find that you can’t stand it up or reliably lean it against a wall etc. To rest it, you have to lie it horizontally on the floor, which seems awkward. Still, it’s proved much more convenient than my previous wired cleaner, which was of good quality and powerful, but a pain to drag around and keep plugged in. So, recommended.
Excellent all rounder except for battery life.The manufacturers say you can clean the whole house on one charge …maybe if you don’t use the plus butto
I like the design and functionality. It is lightweight. I was able to vacuum the whole house, with plenty of battery power remaining.
Best hoover I have used great for around a small new build house. Brilliant on my stairs carpet when you take the attachment off and have a small hand held for each step plus the turbo button for carpets is a great feature. Overall very pleased will never buy an upright agai
Firstly, it is important to say that in the main we have been really pleased with this Vax PWR blade 4 and are glad we purchased it. We have had it for about 18 months now and in terms of convenience and ease of use in normal operation (for a quick vac all around the house or in one particular room) it is really good. However, we also have a ‘Hetty’ (Henry) type vacuum too and I think we would struggle if we didn’t have both. We have found a few drawbacks with the Vax:
1a. Brush bar – gets clogged very quickly (at least in our house) – I have my wife two daughters and a springer spaniel and it seems I am forever removing the brush bar because it gets quickly clogged with hair, bits of cotton / string etc and if you don’t deal with this regularly the brush bar stops picking up and eventually jams.
1b. Brush bar and 3 year warranty issues – also the brush bar started making some very bad noises and had to be replaced – we had the ‘3 year’ extended warranty so I thought it would be free of charge but when you read the small print the 3 years warranty only covers the ‘main unit and not accessories’ – Vax counts the brush bar as an accessory (which I was very frustrated at because clearly it is not an accessory and is integral to the vacuum) and despite the fact it was just a few days out of its one year warranty Vax were unprepared to replace it for me so buying one from them wasn’t cheap – really disappointed with Vax on this one
2. Poor hand held Vacuum – despite how it looks on the video, I was really disappointed at how difficult it is to turn the normal vacuum into a hand held ‘dust buster’ type vacuum (it is quite stiff and difficult to pull apart – you have to wrestle with it and use quite a bit of force) and then how poorly it performs when you do. I have tried it around the house a few times (to get the collecting dust off bit of carpet next to skirting board that the vax with brush bar doesn’t seem to get) and in the end I find it easier to lug out the Hetty than use the Vax for this. Also when buying this I had one eye on being to easily and quickly vacuum the car – tried it a few times but reverted back to our Hetty vacuum because it was so difficult to do and didn’t do a very good job
3. High power drains charge. Battery life is excellent on normal power, but if you use it on high power then it drains very quickly – high power is really great in terms of suction but you would have to move quickly to vacuum a whole house on this setting
4. Constant emptying – we have had to get in the habit of emptying the vacuum every time we use it as it does not have much capacity at all and soon gets full. The dust collector unit is quite easy to remove but the dust and debris doesn’t often simply ‘fall out’ so you need to be prepared to pull at the fluff etc or take the top bit off and remove the centre section which then gets a bit faffy. Replacing the dust collector can be a bit tricky at first but once you get the hang of it usually happens quite easily.
As I say, we are generally pleased but be aware of those issues before you buy
Chuffed with this battery vacuum, good suction, decent battery life and a very competitive price.
Bought for my Mum liked it so much I bought one too!
Good Hoover. I find it a bit on the heavy side. Not as lightweight as dyson. Suction is good and brings pile up on carpets.
I love this hoover it’s lightweight ,good battery life and easy to clea
Just fantastic! A* in every respect!
Just wish I’d bought one before, since Vax 4 blade is so easy to action, even though I am over 70!!!
Great suction, easy to empty, hangs on the wall out of the way, brilliant for the car, quick battery charger..excellent vac!
This replaces my dyson and is the best hoover I have owned can’t find the words to express this enough
Neat and efficient little cordless vacuum. Only used it 4 or 5 times since purchase but happy with it. Great feature that it can be dismantled easily for hand held use eg stair carpets. Battery charge sufficient for 3 bed house although we have wooden hallway downstairs. Wall mount facilitates neat storage .
The vax is very light & the battery life is better than expected. I especially like the lack of bags, just tip out the simple container easily.
After buying a cheap Hoover my daughter took it back so I bought her this one as I’ve wanted one myself. She was amazed buy the suction and couldn’t believe how much dust it got out. So easy to empty too.
I have been using a Dyson but it was not very good picking up bits. This one is far superior , more powerful, had a light on front which is super for seeing in corners. Very impressed
Definitely needs boost mode for carpets otherwise great for tiled floors.
Had trouble carrying my old vacuum cleaner upstairs and this one is just a perfect weight. Also not having to plug it in while moving from room to room is a godsend.
Very easy to use and good manoeuvrability, the light a bonus, easy to empty, also enough time to clean on battery. Very pleased with it.
Suction not great and battery does not last 45 mins. Useful but there are better cordless models.
Really pleased with this. So much easier to use than that Dyson ball vac we had before. There suction power is impressive. The detachable battery means we don’t need to keep the whole unit near a power point, just the battery.
I’ve been using this Vax for a good few months and have been very impressed with it. I’ve owned several vacuums including the Dyson V8 cordless. The Dyson was great, to begin with, but quickly lost suction power and the battery died too fast.
The suction power of this Vax is excellent and I love the main cleaning head as it works well on both carpet and hard flooring. Unlike the Dyson V8, this had an independently controlled roller brush that once switched on allows the vacuum to glide over hard flooring. This option also turns on the front LED headlight which helps massively to see dust and debris that would otherwise be invisible in normal light.
The second thing I love about this vacuum is the removable battery and separate charging cradle. It means I have never run out of juice as I did with Dyson. This lasts anywhere between 30 to 45 mins depending on suction mode.
In term of handling, this design of this vacuum takes a little getting used to. It seems heavier to handle compared to the Dyson, even though they’re similar in size.
One thing that seems to never get mentioned is the easiness of cleaning. This is easier than Dyson to empty and clean. Dust would always get stuck in the Dyson and I’d have to get my hand in to remove it. On the Vax, just open the flap, empty, done.
Overall, this is as close to the perfect cordless vacuum cleaner you will get. I love it! Much better than the Dyson V8!
