Get roomba at Costco. It won’t mop, but it will get off the charging station, sweep and go back.[/quote]
Do you have one? Does it transition well/at all between tile and carpet?[/quote]
We got one about four years ago. Replaced the battery about a year ago (~$50). Unlike SK we are happy with the results – the wife would likely pick roomba if she had to chose between me and the machine. There is a mop version, but the reviews were not good so we did not get it. Most models have 4+ stars on Amazon and the Costco price was $100 better than the Amazon price.
We have 65% hardwood and 33% tile (2% carpet in one of the closets) and few area rugs. No pets.
