I bought my Roomba as a gift to myself for my birthday in March 2009. By June 2009 the product was useless. I tried to clean it as instructed, changed the brushes etc and the thing would still not work poperly. I sent emails to customer service at iRobot numerous times with no response. Finally I called them in November 2009 and asked to return it thinking I had a 1 year warranty. SURPRISE! Its a 30 day warranty! A toaster has a better warranty than that! If you get a Roomba realize you will spend more time cleaning it than you will getting use out of it. Do not bother buying anything from iRobot. Poor product, poor warranty, poor customer service. In other words, Junk!
