Bests & Worsts Reviews from Amazon

I've got three Roomba 500s (a pair of 560s and a 570), and I love 'em. Rock solid reliable, easy to work on, and do a great job keeping my floors clean. These Roombas aren't toys, they actually clean the floors. In fact I've gone behind them with my Dyson just out of morbid curiosity and all I got was an empty bin. Sure, a Roomba can't pick up as much dirt as a regular vacuum in one pass, but that's why they're programmed to cover the same area of carpet multiple times. And in some ways the Roomba is better than my Dyson. Why? Areas of my house that get vacuumed every week without effort: * Under my bed. * Under my dresser. * In the back corners of my closet where a regular vacuum can't go. * Underneath my reclining theater seats. * Under my basement work bench and utility sink. * ...and on and on... The 600s series is even better, as they include the Aero Vac dust bin, and the upgraded cleaning head module from the 700 series. The upgraded cleaning head module is a bit of a big deal, as it's designed to keep the bearing clean and should result in a much longer lasting robot. In fact just last month I had to replace the cleaning module on my oldest 560 as it had gotten gunked up and warped from heat. Easy to fix, but the replacement module and compatible brushes were about 70 bucks. So if you're considering an older 500 series Roomba to save a few bucks don't! Anyway, bought this one for my Mom and she loves it. The only complaints I would make are: * Only one invisible wall is included with the 630. * Unlike my oldest 560, and my 570, the 630 doesn't support lighthouses. * When you first get one you'll have to "Roomba-proof" your house. Meaning the robot will get caught on curtains, rug tassels, etc, and you'll have to fix or remove these obstacles. It's a simple process, but just be aware your robot will get stuck on some things at first. * The upgraded cleaning head module is nice, but why can't we get one with completely sealed metal bearings? The reason I think is that the robots would essentially last forever at that point and Roomba wouldn't make as much money.
