has some benefits It's clean, removes grime and pollen, and doesn't make a ton of noise. A big benefit is that you no longer have to clean the brush after each use because the wool and hair are no longer twisted around it. And there are drawbacks to that. It seems to have sucked in quite weakly, from a not high carpet it could not handle cat hair. The battery is poor, draining 40% in 30 minutes of hard cleaning. It's inconvenient to clean the trash can while it's full, therefore you should invest in a self-service cleaning facility.
