Abstract: A cleaning machine for cleaning along an intended direction of use includes a drive assembly, a cleaning element, and a multi-directional wheel. The Drive assembly includes a motor and a pair of drive wheels operable connected to the motor. Each wheel of the pair of wheels can be configured to be driven independently of the other wheel. The cleaning element can be disposed forward of the pair of drive wheels along the intended direction of use of the cleaning machine. The multi-directional wheel disposed forward along the intended direction of use of the pair of drive wheels. The multi-directional wheel can define a pivot axis and can be configured to swivel about the pivot axis in a range of direction extending 360°.

Abstract: A method of controlling a robotic floor cleaning machine includes driving, by an operator, the robotic floor cleaning machine along a transport path and a cleaning path. The transport path defines a path for transport of the robotic floor cleaning machine without active cleaning and the cleaning path defines a path for a cleaning operation. The method further includes recording the transport path and the cleaning path driven by the operator; defining, in a controller of the robotic floor cleaning machine, a route comprising the recorded transport path and the recorded cleaning path, and defining the cleaning operation. The robotic floor cleaning machine executes the defined route and the cleaning operation.

Abstract: A floor cleaning machine can comprise a chassis, a cleaning mechanism, a control system, and a cleaning operation sensing system connected to the chassis. The chassis can be configured for movement along a cleaning path. The cleaning mechanism can perform a cleaning operation. The liquid system can provide liquid to the cleaning mechanism. The recovery system can recover liquid from the cleaning operation. The control system can control performance of the cleaning operation. The cleaning operation sensing system can detect a condition of the cleaning operation. The cleaning operation sensing system can comprise a water trailing detection system comprising: a frame connected to the chassis aft of the recovery system; an absorbent medium connected to the frame; and a moisture sensor in communication with the control system to alter a signal in response to moisture in the absorbent medium.

Abstract: A control system for a robotic floor cleaning machine configured to perform a cleaning operation along a cleaning path can comprise a controller, and a plurality of sensors. The controller can be configured to control autonomous movement of the robotic floor cleaning machine along the cleaning path and autonomous performance of the cleaning operation. The plurality of sensors can be configured to sense a location of the robotic floor cleaning machine relative to surroundings of the robotic floor cleaning machine. At least two sensors from the plurality of sensors are configured to locate the robotic floor cleaning machine in overlapping areas of the surroundings.
