Constant dry cleaning was needed - there are two very woolly cats at home + dust from the street flies into the windows. Handles like hell to do! It's nice to walk barefoot at home, plus it saved me time, I love it. Not hyper-noisy, keeps a map of the room in memory, divides the space into squares, crawls around the perimeter, then removes this outlined square with a snake. In general, there are no complaints.
