I bought one of these from Meh previously. I was skeptical that anything with such a small dustbin could be useful. I run it upstairs daily and it has made a world of difference in how much dog hair accumulates. Each day it picks up enough hair to knit a small dog.
I bought this last month. Works well on wood floors and a low-pile rug. Doesn’t fall down the stairs. Cleans up the pet hair. Good deal. Has two little blue lights, like eyes, that come on when it’s doing it’s thing. Makes it look like the Night King took a dead Roomba and resurrected it as a White Walker iLife robot vacuum.
Bought this previously and have been happy with it. Good runtime, effective with pet hair (have a very sheddy dog) on wood floors. It does not have a beater bar so probably won’t be as effective on carpet.
