Pros: Difficult to think of any.
Cons: Poor repair service. Cleans poorly. Tangles cord.
Unit has worked for a year, cleaning with mediocrity, tangling the cord every time. Recently, it stopped working, no power to the robot. It was sent to Maytronics USA (US representative and service center.) It was repaired under warranty with decent speed. When returned, worked for an hour before the power supply blew another fuse. Same problem as when it was sent for repair. I await their response, but so far not impressed with the quality of their repairs. My conclusion that the unit is overpriced and performs worse than expected remains valid.
