The product looked great, you hardly notice any difference to a new appliance. And the hoover is currently working quite well ;)

The appliance vacuums excellently, even cat hair without any problems. Emptying is super easy and quick.

I recently bought the vacuum cleaner and was delighted with it from the first time I used it. It sucks up everything that gets in its way, such as dog hair and dirt. On the carpet it increases the power by itself as described so that everything on it can be vacuumed up even more effectively. Then the roller... Perfect, no hair gets stuck on it that you then have to tear off the roll with your hands. Battery also very good and the vacuuming of the dirt into the container works perfectly In a nutshell..... Buy it, I love it and could vacuum something all day hihi

I unpacked it and put it together. The battery was even charged. The vacuum cleaner is intuitive to use. Thank you very much.

The autonomy is far from the 40 minutes described, so we're deducting points for that. I can't do my 100m² in one go. Another minor fault is that it often locks up mechanically in standby mode (all it takes is a little kick for it to start up again), not serious but worth noting. The rest is excellent: self-draining, performance, noise level, light, easy to dismantle and reassemble, very light... Very satisfactory overall.

The vacuum cleaner is great and sucks well. The only drawback is that it doesn't stand on its own and stops on higher carpets.

Super hoover, you should only note that the filter likes to "clog" sometimes but this can be remedied by placing it on the station.
