    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.

    Golden Review Award: 7 From Our UsersI assembled my machine fairly easily (I am 82 years of age) and decided to try it out on my lounge carpet, which had been vacuumed that morning with my Buture cordless vacuum. I could not believe the amount of dog hair that came into my new machine, totally filled the container. Such a shock, as I thought my existing machine was doing a good job with my Smooth Coat Collie’s hairs, which drop all the time.

    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.

    Golden Review Award: 15 From Our UsersWe got this to replace our old cleaner made by a well known bag less vacuum company beginning with D after several expensive failures over the years.
    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.

    Golden Review Award: 8 From Our UsersI would like to apologise profusely for being a traitor to Vax and trying different hoovers over the past few years. The Dyson was the biggest engineering con ever. It went on fire!!!! The engineering dept at Dyson said they do and replaced it no quibble! It was binned when the replacement ignited shortly after arriving. Th

    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.

    Golden Review Award: 5 From Our UsersGreat hoover but battery pack is heavier than anticipated – especially for my 89 year old mother. Took her a bit of practice to empty the cannister. Comes with a fitting to attach to the wall for it to stand up, which it needs as it falls over due to the weight and position of the battery. Would recommend, and was good value compared to others on the market, but be aware of the above.

    Golden Review Award: 7 From Our UsersIt’s lightweight and easy to manoeuvre. It cleans hard floors really well. The battery life is more than enough. It doesn’t have anti wrap hair technology so the vacuum head needs cleaning a bit more regularly if you have long hair.

    Golden Review Award: 27 From Our UsersI didn’t set out to buy a vax but after reading the reviews I was impressed and now I am impressed with the vacuum itself. Why 4 stars? The batter life doesn’t last long especially if you have it on full suction, which I do. It last about 15mins BUT it is well worth the time to recharge because in all else it truly excels any cordless vacuum I have had to date. I work my cleaning around recharging which takes no time at all OR I hoover little and often ie. each day. I am thinking in investing in a second battery but am hesitating because I really don’t need it. I’d definitely recommend this vacuum to anyone thinking of purchasing one. In my mind it was definitely worth the money which in fact was cheaper than any of my previous brands and the one I had originally intended to buy.

    Golden Review Award: 5 From Our UsersIn all honesty I can’t give this tool a five-star. True it is very convenient for some jobs. Unexpectedly I find it irritating to have to charge the batteries, having started a job with not enough battery life. It is heavy when not in use – especially when going upstairs. It does not, for example, pick up the leaves that may fall off a houseplant (of which I have many}. You physically have to lift it on to the leaves using the extra suction! That said it is a quick/useful gadget when on the flat and brilliant if you spill powdery type waste!

    Golden Review Award: 7 From Our UsersGood suction love a vax but don’t let it drop this is my 2nd one in 6 months it fell and the doors on dust catchers and filter wouldn’t close the brush would not go round and led light didn’t work other bits came off. It wasn’t dropped from a great height it just slide down the wall I leant
    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

    Golden Review Award: 34 From Our UsersThe Vax Blade 4 performs pretty much as well as our old handheld Dyson at a fraction of price, so that’s an easy plus in this vac’s favour. Some quality of life features like the LED lights on the head, and the spinning carpet brush are neat too.

    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. 😉

    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.

  29. ChristineBoatma says:

    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.

    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

    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!
