iRobot Roomba 552 Pet Series The new 500 Series robots offer the latest innovations from iRobot with unprecedented efficiency, coverage and cleaning performance. AeroVac is a single chamber vacuum bin that holds more debris and fills evenly inside the bin, allowing you to empty it less often. Auto Virtual Wall is always on and ready to keep Roomba cleaning where you want it by restricting off-limit area. Automatically returns to its Home Base to dock and recharge between cleanings. Reaches deep into your carpet to remove dirt, dust and pet hair. Efficiently cleans the whole floor, under and around furniture and along walls. Automatically adjusts to vacuum carpets and hard floors. Roomba senses dirtier areas and cleans more thoroughly in those spots. Simple to use - Just press the Clean button, Roomba does the rest. Roomba wont get stuck on cords, carpet fringe, or tassels. Using clean, hair-free brushes ensures that Roomba always cleans at peak performance.
