Light weight and efficient

Lightweight, very easy to use. Re charges quickly. Easy to remove hand held from base. Dust chamber holds more than i thought it would.

good but not great

it has a nice swivel head that works very well at navigating corners, it is light and stores nicely. The issue I have is it is not very strong in suction when you take the hand held section out. its odd head makes it awkward to use and i find the attachments useless. When you do use the upright full vacuum because of where the dust collector is, it doesn't go under small spaces, I should have thought of that before purchasing. I would recommend spending more and getting a better design.

Pros: comfortable to use, easy storage, good around corners, light weight, not too noisy Cons: attachments useless, getting under objects, hand held nozzle weak, hand held suction poor

Great cordless vacuum but not for dyson money

Easy to use easy to assemble great pick up great swivel head pick up stairs are a breeze with this equipment just 1 fault it needs a long attachment to reach in higher places


Very lightweight easy to use I have 2 cats it picks up their hair with ease I am so pleased I chose this one. It's also very easy to clean out. Above all its purple.

Fabulous Cordless Vacuum!

I've been genuinely very impressed by this cordless vacuum from Vax. It was very easy to assemble and took less than a minute to put it all together. It took around 4 hours to charge for the first time - and for that I got about 35-40 minutes run time on the strongest setting, which I was happy with. It's lightweight and portable, and the main unit swivels on the base, so you can get into corners very easily. You can use it on both carpets and hard floors, so that's great! The purple unit removes so you can use it on the stairs, or even in the car. It also comes with a couple of attachments to make things easier for you in smaller or hard to reach areas. The attachments fit onto the side of the charging base too, so I liked that attention to detail because I'm normally guilty of losing things! It's easy to empty the dirt it has collected too - you simply release the compartment, pull out the filter, and empty the contents into the bin. I like the fact it comes with a 1 year guarantee from Vax too, so that fills me with confidence that it's a quality product from a reputable manufacturer. Based on my experience with it, I'm more than happy to recommend!

Pros: 1 Year Guarentee, 2 speeds to choose from, Easy to Assemble, Lightweight, Powerful

Wow, fantastic product This cordless Hoover doesn't half pack a lot into a small lightweight Hoover. It is ready to use when fully charged for a full 45 minutes, it's lightweight you can carry it with one hand perfect for people with bad backs (like myself). I have 3 dogs one is a Scottish deerhound who sheds hair a lot I thought it would of struggled to pick it up but no it made easy work of it. It also has a handheld part you can take off which is great for easy pickups it's got such a powerful suction on it to. Only downside to it is you have to empty the cylinder a lot more but I think for the things it does and how lightweight it is it's fine for me. It also works well on laminated floors, tiles and carpets. It also has a slow speed which is good on laminate and fast speed for carpets. If you are looking to purchase a cordless Hoover I can't recommend this one enough, you won't be disappointed.
