Great features
We purchased this vacuum3 weeks ago and picked it up very quickly from the store and also very pleased with the product

Nice and smooth
My partner is happy with his new toy. The only thing is the battery life but we bought a bigger one on amazon, so can swap anytime. It‘s a handy hoover, not too heavy, not too loud. Since we only have it for a couple weeks, will see how it‘s going in the future. Much better than our Hetty with cable and her own mind anyway ;o)))

Bosch unlimited 9 vacuum cleaner
I bought this for someone else as I already have one, the best vacuum cleaner I have had, the person it was bought for is full of praise for it as am I. Also if you register it with Bosch you get a 10 year guarantee, who else does that, excellent product, definitely recommended by me.

Had this cleaner for about 2 weeks and found that the emptying was a bit fiddly to get the dust bin back onto the body and sometimes the vac itself slows down when in operational and putting it back on charge is a bit tricky to if you have not got it quite right apart from that not to bad.

BOSCH Cordless Vacuum Cleaner
I especially like the digital readout of how many minutes are left in the battery. I like the different settings. I like the ease of using it - the tamping down of the dust in the collecton box. I do not like not being able to have the attachments on the stick to use as and when needed - if I forget to carry them, I have to go back to the vacuum station to collect. I do not like not having more attachments like a turbo head. I do not like the fact that if I want additional attachments etc I have to buy them extra.

Great vacuum cleaner, looks great and is very easy to use. The only downside is the short-lasting battery, counted more in units of use than minutes.

Perfect!
Very pleased with this hoover. It is much lighter and quieter than my previous one. I have a dog that moults constantly so it’s important I am able to hoover both hard floors and carpets more than once a day. The battery charges rapidly and on auto mode it lasts 14 minutes which is ample time for my 120 square meter downstairs. Because of my dog I’m a bit ocd about keeping the hoover clean and this one is the easiest to clean I’ve ever seen! There is a button to press to empty the collection chamber and then a lever that pushes out any remaining debris. There is a neat system that helps to clean the filter. You just twist the filter and the dust falls out. Everything comes apart so I am able to get to every nook and cranny. That wasn’t possible in my previous hoover. For cleaning stairs you can attach the cleaning foot to the handle so it’s easier to use. The cleaning foot is quite narrow so can fit easily in small nooks. I miss the ability to break the hoover to clean under sofas etc but the benefits more than outweigh this downside. Would recommend it to anyone that needs an efficient cordless hoover.

Hello Ollie, Both vacuums are suitable for multiple flooring types so it would be personal preference . The Bosch unlimited 9 cordless Vacuum s designed to prevent hair tangling, making it suitable for homes with pets. The Bosch Unlimited 7 Auto Detect Cordless Vacuum is designed to effectively handle pet hair, particularly the ProAnimal variant, which features a mini brush roller specifically designed for pet hair removal. Which one you choose would be up to you but both vacuums seem to be suitable for you.
Thank you for using Argos Q&A.
