Our 18 yr old is leaving home. One of his chores was vacuuming the kitchen tile floor. We bought the robot (to replace our teenager) just expecting it would do an ok job on the tile. We've had it for almost one week now, and are delighted with its abilities both on tile and on carpet. The tile floor is done at least as well as our son would do it, the results on the carpet FAR exceeded our fairly modest expectations. The dust catcher does get full fairly quickly but the roomba can do a pretty large size room and find its way back to base with no apparent difficulty.It's super easy to use (plug in, charge, press clean) and we would recommend to others, especially with lots of tile and no time! We plan to use it every other day on our tile (we have dogs) and alternate with a carpet room.
