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 random orbit scrubber comprises a main body having a front end and a rear end, a squeegee assembly coupled to the rear end of the main body, and a cleaning head assembly coupled to the front end of the main body. The cleaning head assembly can include a cleaning element structured for contact with a floor surface. The cleaning head assembly can further include a motor that is operable to impart rotational and orbital movement on the cleaning element. The cleaning head assembly can also include one or more arcuate cleaning fluid manifolds each having a plurality of dispensing points to distribute cleaning fluid in one or more locations on top of and in front of the cleaning element. The arcuate cleaning fluid manifolds can include variable flow nozzles and can be mounted to a carriage that rotates about the cleaning head assembly.

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 method for collecting garbage from a surface includes providing a motor-sweeper including a sweep broom. A rear guide is provided between the sweep broom and the collecting container extending downwards from the collecting container close to the sweep broom. The sweep broom rests with the guide assembly onto the surface, and the sweep broom is rotated in order to collect and convey the garbage into the collecting container. The rotation of the sweep broom causes the garbage to be swept forwardly and upwardly with respect to the forward motion of the motor-sweeper. In response to the bristles of the sweep broom wearing, the sweep broom is moved toward the surface and the guide assembly and the rear guide are moved towards the sweep broom so as to maintain uniform spaces between the sweep broom and the guide assembly, and the sweep broom and the rear guide.
