iRobot Brush Retainer with Wire Bale for Roomba 400

An important part of the Roomba is its system of brushes that sticks out past the robot shell to reach spots the underside cannot access. It spins along walls to kick up dirt and direct it into the vacuum area. The brush on the opposite side of the Roomba directs any wayward dirt back under the unit to be sucked up.

In order to keep the robot efficiently working, the user occasionally needs to replace the brush retainer with the wire bale, which is a part of the robot that goes over the brushes to help prevent cords from getting tangled. The brush retainer with wire bale can be purchased directly here.
