I was very enthusiastic about owning this remote control floor vac after reading some glowing reviews. However, it failed miserably in living up to my expectations. It does not do any of the things others owners claimed it would. I tried using it on tile and it would stop and start and stall where it hit the grout lines. It failed to transition from tile to low density area carpets; it did not want to run on low pile carpeting and it continued stopping and starting arbitrarily. I would strongly recommend that if you want to have a robotic auto cleaner vac, you consider "paying the big bucks" for a major brand name as I'm assuming they will work properly. I tried it and am returning it after the first very disappointing trial use. I have used Overstock in the past for other products which were terrific and I will continue to shop Overstock for good quality items and good prices. This particular item does not meet that description.
