It is a rectangular black plastic frame with metal rods across it that prevent debris from entering the brush. Over time, the brushes may become entangled with debris, or even dislodged due to an ineffective brush guard. In some cases, the brushes may even fall out o the Roomba. This guide will show you how to replace the brush guard on a Roomba 4160.
