Electronic vacuums
This isn’t a paid endorsement, but the $400 bucks we spent on our vacuum-cleaning robot is probably the best investment we’ve ever made. The high-end model includes a scheduler and will re-dock itself at its charging station when it’s done working. All you have to do is empty the dustbin a couple of times a week. Seriously. It’s nice to have, especially if you have free-range hamsters. We recommend Roombas from iRobot.
