Vax blade 4
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.
Does the job well
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.
5 star rating Vax cordless hoove
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.
Excellent cordless cleane
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.
Convenient & effective.
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.
Vax is back
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
Much improvement on a corded appliance. Much handier for a quick once around.
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.
Does Exactly What I Need It To Do
I bought this basic model a few days ago primarily for flat floors and my car. I don’t intend to use it for carpets as I have a cheapy little cylinder corded hoover for that which does an excellent job. I also have the additional tools from a previous Vax – these tools are a game changer; Vax are offering them free with this model in their summer sale.
As ALL rechargeable hoovers loose substantial amounts of run-time if the boost or turbo options are employed I decided to test my Blade 4 on normal power alone using the soft brush and crevice tool provided with this model. This is what happened:
It has 4 bars to indicate how much charge it has in it – it had 2 bars showing on arrival so, as per the instructions, I charged it up to full power. There’s only one carpet downstairs in my house; the rest is all flat flooring which seems to generate dust practically by the hour. On normal power, fully charged, I hoovered thoroughly the following: kitchen (vinyl floor), dining room (vinyl), little downstairs loo (vinyl), large hallway (quarry tiles), large downstairs family bathroom (ceramic tiles). Still on 4 bars. So with the soft dusting brush I hoovered all the downstairs windowsills (11 in all), the tables, the piano, a few intricate wooden ornaments, the curtains and the lounge furniture. Still 4 bars. (I’m beginning to run out of things to hoover now!) So I hoovered the large stone fireplace and hearth in the lounge, the grate, the fire utensils and then the stairs using an attachment from a previous Vax. Finally! – it’s just changed to 3 bars. So I then used it to clean the interior of my car (using the tools I already have) and I still apparently have 2 bars left.
I emptied the dust bucket twice during the experiment (I didn’t let it get full) and kept it on normal power throughout. I’m impressed – that’s a lot of hoovering on a lot of different surfaces – there’s not a speck of dust left anywhere. I don’t know how accurate the bars on the charge indicator is, but time will tell. On doing a bit of research, the clue to prolonging the overall life of these batteries is to keep the filters clean and the vacuum free of blockages.
As other customers have mentioned, engaging and disengaging the various components (except the battery) does need a bit of muscle power, and the unit is a bit top heavy, but for me that’s not a problem. Some people have had problems with hair and thread wrapping round the brush head – this model, without the pet tool attachment, does not claim to be anti hair wrap, so scissors would almost certainly be needed if it’s used on carpets.
I’ll update this review in a few weeks time, but for now I’m happy to give it 5 stars.
