See how well Roombas and other robot vacuum cleaners work on stairs, hardwood floors, with rugs and other obscacles. I like iLife robot vacuums because they’re more affordable. (Actually, I have two — one upstairs and one downstairs!) These photos and videos tell the whole story about the iRobot Roomba and other popular robot vacuum cleaners — HOW they work, how WELL they work, which are the BEST ones, and how to CLEAN them. My personal experience with robot vacuum cleaners and pets.
