Abstract: A lawnmower, and in particular a robotic lawnmower, can include a passive cleaning assembly for removing detritus from the lawnmower housing. The passive cleaning assembly can be moveably mounted on the housing. Movement of the lawnmower with respect to the ground can cause a cleaning portion of the passive cleaning assembly to move with respect to the housing, and thereby remove detritus from the housing.

Abstract: An autonomous apparatus, such as an autonomous robot, maintains wood decks by automatically cleaning and staining the deck while traversing the deck in a manner so that the cleaning and staining is performed in accordance with an organized navigation pattern along the deck boards.

Abstract: A lawnmower which includes a housing, and a passive cleaning assembly for removing detritus from the housing, the passive cleaning assembly being moveably mounted on the housing. The passive cleaning assembly can include a ground-contacting portion, which contacts the ground during use, thereby causing the cleaning portion to move with respect to the housing during movement of the lawnmower. Movement of the lawn mower with respect to the ground causes the cleaning portion of the passive cleaning assembly to move with respect to the housing and to thereby remove detritus from the housing.

Abstract: Aspects of a lawnmower and in particular a robotic lawnmower are disclosed herein. Specifically, the lawnmower may include a passive cleaning assembly for removing detritus from the housing, the passive cleaning assembly being moveably mounted on said housing. Movement of the lawnmower with respect to the ground may cause a cleaning portion of the passive cleaning assembly to move with respect to the housing and thereby remove detritus from the housing. In one aspect, the lawnmower may be configured such that, during use, the cleaning assembly is moved with respect to the housing thereby causing a scraping edge of a cleaning portion of the cleaning assembly to move with respect to the housing and thereby scrape detritus off the housing. In another aspect the lawnmower may comprise a sliding member having a ground-engaging surface that is positioned so as to face towards and to slide over the ground during such movement of the lawnmower over the lawn.
