Robot vacuum with empty station works well, only had for a few months. Works well on dust and dirt.
I am only getting rid of it because I have numerous pets and it requires manual emptying somewhat frequently. The bin has a comb to collect hair/fur and my house has too much of that.
If you have 1 or 2 pets it should work great. Retails for $500
Bins, brushes, rollers, and filters have been cleaned.
