Negative Positive
Title: Needs lots of help
Review: My home is only 600 sf with mixed hardwood and low-pile carpets, but Roomba has only managed to find its way back to its charger/base once in over two months of daily use. Although I clean it out after every use, it gives up and stops in its tracks if the roller and/or wheel mechanisms get too wound with dog or cat hair; if it finds itself with one wheel on a rug and one on a floor; and sometimes for no apparent reason at all. Customer support from i-Robot has been virtually nonexistent.It's a fun toy, but I would not buy it again.
