The new iRobot Roomba 880 has dispensed with with brush cylinders in favor of spinning thermoplastic polyurethane tubes. This new design makes the Roomba quicker, quieter, and barely need any maintenance.
In the grand scheme of things, it really doesn’t get much better than an autonomous robot that cleans up your messes while you’re off doing whatever. Even so, it’s never an entirely hands-off process. Your hands will become intimately reacquainted with all the disgusting gunk that’s been hiding in your carpet as soon as you clean the vacuum’s brushes.
