I unfortunately would have to put a big thumbs down
on purchasing either a scoomba or roomba. I have two roomba's (1 for upstairs/1 for downstairs) and within a year they have both messed up on me. One just goes in a small circle then beeps and shuts off and the other one just beeps and goes to a recharge light. I have tried swapping batteries and that didn't work, have tried resetting both and that didn't help either. I also purchased the scoomba (floor washing machine) and after about 4 months it doesn't work either....it won't dispense the floor solution at all. I have tried to contact the company, but haven't gotten very far at all.... sooooooooooo in my opinion I wouldn't waste my hard earned $$$$$ on any of these...
