Satisfied, more convenient broom. I use more than a robot vacuum cleaner. Has some pros: Always at the ready, collects dust and wool, maneuverable. In 10 minutes you can run around the entire apartment (odnushka) without moving the furniture. The back is not tense. Easy, you can trust the child. With its cons: I have shoulder-length hair, it turns out there are a lot of them on the floor - they are wound on a brush, I have to periodically cut them off the brush with scissors. I dismantled the brush a couple of times and cleaned it of hair, otherwise it would be a complete stopper.
