Abstract: A method of surface type detection may include traversing a cleaning area, generating a plurality of cluster points while traversing the cleaning area, each cluster point being associated with a corresponding surface type and a location, and determining at least one surface type region within the cleaning area based, at least in part, on a comparison of the plurality of cluster points.
