Perfect for daily cleanups
[This review was collected as part of a promotion.] I like the design - it looks modern and the color combination is nice. It charges directly with a cable, so You dont need a charging dock or stand. This makes super easy to store away. I'm not a fan of upright vaccums because they can be hard to Reach some spots, for example underneath furniture like bed. But this one detaches into a hanheld vacuum so can Reach corners And the brush attachment Has soft bristles which is great for dusting various surfaces, clean the sofa , car inside etc. Suction power Is good, also It Has built in light on the Main floor nozzle which makes easier to see all dust. IT doesn't have the same suction power as corded vacuum (i'm still the biggest fan of these ) but its absolutely good for quick daily cleanups without having to drag out And set my usual vacuum. Battery life is ok, enough to clean average size flat. Overall - convinient And realiable for everyday use!

A great vacuum!
[This review was collected as part of a promotion.] A very good vacuum, light and comapct and also very easy to change to handheld and also can be used on hard floors and carpets using different settings. Love the colour and was easy to put together, the light on the front is so handy. It’s easy to empty also and the battery lasts quite a while!

Powerful, lightweight vacuum
[This review was collected as part of a promotion.] I have to say that I am very impressed with this vacuum cleaner! It is lightweight and surprisingly powerful. It was easy to assemble and is easy to use, in fact my two girls have cleaned their rooms several times with it! It is easy to carry upstairs and I love that there is no cord trailing to trip over! The handheld part is easily detachable and makes cleaning up spills, stairs or sofas so much easier. I love that I can just get it out, quickly whizz round the house and plug it back in to charge. It easily cleans the whole house on a full charge. I like that you don’t have to change settings for different floors, it copes well going from carpet to vinyl. It is also easy enough to empty the dust collected, although I do have to do it a few times if cleaning the whole house. It doesn’t make too much noise. If I had to pick up on a negative, it would be that it doesn’t always pick up things right at the edges of rooms, but then you can just click out the handheld part and use that. The tools are easy to fit onto the handheld part and come off easily too. It can also get a bit ‘stuck’ on the carpet and needs a good push to get moving again. All in all, it’s a great vacuum and is so much easier than lugging a big vacuum around the house.

Perfect for everyday use
[This review was collected as part of a promotion.] I’m really happy with this vacuum cleaner. It’s so handy, light and easy to use. I really like the design and it works well on both laminate floors and carpets. The best thing is that I don’t need to keep changing anything when moving flor one floor to another, it just adjusts itself. Is very easy to empty and clean after use. I love that is 2 in 1 so I can reach under sofa and spaces not easy to get with normal vaccum. Is just prefect and make easy with daily cleaning

Powerful but heavy
[This review was collected as part of a promotion.] There are so many things that are right with this, it's just a shame that the main problem is that it's so heavy! The stick itself is fairly light, but it's the detachable handheld that carries the weight, which you notice more when you're trying to vacuum up high (getting rid of cobwebs for instance) Out of the box it's so easy to put together and takes no time at all and there's a place within the vacuum for the attachments so no need to worry about them getting lost. Compared to other vacuum cleaners it's quiet in comparison, not silent but quieter. The suction is really good, although as you'd expect eco mode isn't the most powerful but gets the job done and saves battery life. And as it takes an age to charge that really is a good thing. I mainly use Auto and occasionally use turbo if there's anything particularly stubborn to get up. Even using them combined the run time was about 50 minutes and it still hadn't run out of battery, which is superb. The filter is rather large and takes up a fair bit of space, which means you have to empty it more often. I hoovered a four bed house and had to empty it twice. Although there are some negatives, the power outweighs them. Yeah it's a bit heavy and you'll have to empty it a bit more but there's no point have a lightweight vacuum cleaner with a big tank that has no power and leaves the floor just as dirty as when you started! This has flaws but it cleans perfectly!

A compact yet powerful vacuum cleaner
[This review was collected as part of a promotion.] Out of the box we had to put one screw in to assemble this vacuum cleaner by Bosch, but it was so simple and straightforward to do. The handheld part slots into the upright section and the attachments are conveniently stored within the upright too. It’s compact and does not take up a lot of space in my house which is great. Suitable for the whole family to use as it is so simple! It comes with different modes - Eco, turbo and auto and each offer a different level of suction for everyday uses. I find even on the eco mode that it picks up every day dirt and muck really well. I love the fact that it is cordless and I can use to vacuum my car with ease. It is also good for cleaning in hard to reach places such as ceilings and top of the stairs! The compartment for the dirt it picks up is quite small so you have to empty a bit more often than your usual vacuum cleaner but honestly I didn’t mind that. It provides great power and suction for our home and I wouldn’t be without it. Really impressed with this vacuum

Fantastic hoover
[This review was collected as part of a promotion.] Fantastic rechargeable vacuum ! The battery life is great, it has a sleek design and very light weight. The only downfall i would say is it only has a small dust compartment however i have not used a recharger-able hover before so this may be standard. That said i find myself reaching for it over my old vacuum

Very good
[This review was collected as part of a promotion.] What I like most about the Bosh Flexxo Series 4 is how practical the design is. It's slim, easy to manoeuvre and the two extra attachments are built into the vacuum, so they're always within reach. The LED lights are really useful for spotting dust and small bits, especially in darker areas. I also love that it can stand on its own, so there's no need for a docking station. It has good suction for everyday cleaning and the battery lasts well for my needs. Overall, a really practical vacuum that makes cleaning easier.

The vacuum I didn’t know I needed
[This review was collected as part of a promotion.] I already have a corded vacuum and a robot vacuum at home. I was thinking robot vacuum is already a life changer and what else can be better than that and I was wrong. I have a super active toddler who constantly makes mess and a 5 months old that constantly putting everything into her mouth. What a great combo right?! 😂 I vacuum multiple times a day so having something I can just grab without plugging in has been a game changer. These are the things I genuinely love: it’s lightweight and easy to carry around the house. No plugging and unplugging a heavy vacuum every single day. It transforms into a mini handheld vacuum which is so handy. I can get all the crumbs off the sofa and baby chair after feeding without bringing out the big vacuum. My toddler can actually help me clean with the mini handheld vacuum because it’s easy for her to handle. I even vacuumed the walls to get rid of the spider webs. No more dusting walls. If I’m being honest, I’ll be getting rid of my big bulky corded vacuum soon because I find myself reaching out for this one more often. I would highly recommend this for those who have small chaotic children like me.
