Methods and apparatuses associated with surface cleaning are described. Examples can include detecting at a processing resource of a robot and via a temperature sensor of the robot, a temperature of a surface on which the robot is located. Examples can include the processing resource shutting down the robot in response to the temperature being at or above a particular threshold temperature, and the processing resource instructing the robot to clean the surface following a particular cleaning path using a vacuum, a scrubber, or both in response to the temperature being below a particular threshold temperature.

A maintenance station for maintaining a cleaning robot includes a housing, a cleaning structure, and a liquid supply assembly. The housing includes a guiding platform configured to guide the cleaning robot to park. The cleaning structure is arranged on the housing and positioned corresponding to the guiding platform. The cleaning structure includes a tank body and a cleaning protrusion. The tank body defines a groove, the cleaning protrusion is arranged in the groove, and the cleaning protrusion is configured to clean a cleaning piece of the cleaning robot. The liquid supply assembly is arranged on the housing, the liquid supply assembly defines a liquid supply port, the liquid supply port is positioned above the cleaning structure and configured to supply liquid that flows into the groove by gravity.

An ultrasonic cleaning tool for cleaning a surface has a transducer and a horn for generating and transmitting vibrations to a surface to be cleaned. Cleaning solution can be supplied to the ultrasonic cleaning tool or the surface to be cleaned, and operation of the ultrasonic cleaning tool can agitate the surface and cleaning solution. The tool can be provided as part of a system for cleaning a surface, and the system can include an extraction cleaner or a cleaning cloth.

An autonomous floor cleaning robot includes a robot body, a drive supporting the robot body to maneuver the robot across a floor surface, a pad holder attached to an underside of the robot body and configured to receive a removable cleaning pad, and a pad sensor configured to sense a pad type identifier on a central region of the cleaning pad. The pad type identifier includes a marker on the central region of the cleaning pad. The cleaning pad has a mounting card affixed thereto, and the pad type identifier includes an array of apertures that expose selected portions of the marker.

A mobile cleaning robot can include a body, a drive wheel, and a wheel stop. The drive wheel can be connected to the body and can be operable to move the mobile cleaning robot about an environment. The wheel stop can be movable with respect to the body and the drive wheel between a stop position and a release position. The wheel stop can be engageable with the drive wheel in the stop position to limit vertical travel of the drive wheel with respect to the body.
