We bought my aging mother-in-law an iRobot mopping robot a couple years ago. It still works great and has freed up 30min to an hour of time per day she spent cleaning up the floor (they're Korean and spend a great deal of time doing activities on the floor so floor cleanliness is very important).

More importantly, her legs and back aren't doing so well these days and it's eliminated a painful and difficult daily task for her. She loves it almost as much as a pet. Just set it up and forget it for the next hour and the floor is mopped! The biggest problem it has is getting hung-up on her grandkids toys.
