Roomba gets rid of dirt, pet hair, allergens and much more from carpets and hard floors. iAdaptTM Responsive Technology ensures Roomba vacuums every section of your room multiple times, getting into areas you can't easily reach, including under and around everyday obstacles vacuuming until the job is complete. The Roomba 550 Pet utilizes AeroVacTM technology to maximize air flow through Roomba's cleaning head to pull hair and debris off the brushes and into the bin evenly. Easily schedule Roomba 550 Pet to clean whenever and wherever you want-up to seven times per week. The included Virtual Wall® confines the robot from room to room, then guides it back to its Home Base® to dock and recharge between cycles.
