A:Answer Hello CG,
All robotic vacuums need replenishment kits for routine care and maintenance. The accessories available for the 800 and 900 series Roomba include replenishments for the edge sweeping brush (the side-spinning bristles that clean along into corners and along front edge of furniture or baseboards), the dual multi-surface brushes (your main vacuum extractors), and filters. There’s also a virtual wall that creates barriers the robot won’t cross to clean, to protect pet bowls or block off a room, for instance. It’s recommended you replace the edge sweeping brush and filter every couple of months or as needed based on use and wear. The main dual multi-surface brushes should be replaced every 6 months, also depending on wear.
