iRobot Roomba Scheduler 4230 Robotic Cleaner

This product is definitely a help. I gave mine to my aunt because she can't vacuum with even the lightest of vacuums and she is pretty obsessive about cleanliness. Also, she had a smaller house and less to maintain and she is elderly. For her, the ROomba is all she needs in between regular visits from us to help out with deep cleaning. It can work while you are sleeping, too.
If you have pets, keep an eye on them, though. A visiting dog tried to attack our Roomba, so keep that in mind.
But this nifty device does pick up crumbs, pet hair and plenty else. It won't get stuck tar or gum off your floors but hey, you weren't expecting miracles, were you?
