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: Method for operating a dirt collecting device for a sweeping vehicle or for a vacuum cleaner nozzle of a floor or upright vacuum cleaner, which each comprise a suction fan with controllable speed and/or power, wherein in a first method step, the suction power of the suction fan is set at such a low level that the suction pressure in the dirt collecting device or the vacuum cleaner nozzle is merely sufficient to convey and deposit the absorbed coarse dirt into the intermediate container, and to convey the absorbed fine dirt into a downstream collection container, (normal operation); and that in a second method step, the filling level in the intermediate container is detected with respect to the coarse dirt deposited therein; and that in a third method step, if the filling level in the intermediate container is exceeded, the suction power of the suction fan is increased such that the coarse dirt, which is temporarily deposited in the intermediate container, becomes dispersible and is conveyed into the downstream collection container (emptying mode).

Abstract: Apparatus for floor cleaning, having a cavity that opens on the dashboard, a plurality of mechanically similar interchangeable keys, and suitable to be inserted completely into and operate with said cavity, two or more Hall-effect sensors arranged outside said cavity, at least one first key containing at least one magnet, and at least one second key including at least one respective second magnet, which are in functional correspondence with respective predefined sensors.Said magnets do not interfere with sensors to which they are not geometrically connected, and for this purpose they are aligned on a same straight line, and the insertion of said keys causes a movement of said magnets toward the respective sensors with a motion orthogonal to said straight line.

Abstract: The invention provides an autonomous surface treatment vehicle, e.g. a floor cleaner, with an autonomy system navigating according to a map, a scanning sensor to detect a position of an obstacle within a scanning zone and generate a detection signal. A safety system is arranged to generate a safety stop in case the detection signal indicates an obstacle within a safety zone. The safety system can enter a special mode of operation, e.g. upon request from the autonomy system, where a special safety zone selection algorithm selects the safety zone e.g. from a special set of pre-determined safety zones. Especially, such special mode can provide safety zones with a relaxed speed limit in combination with a restricted direction limit, so as to provide a faster driving near a wall or similar known obstacle.

Abstract: Systems and methods include a high dump hopper system wherein a debris hopper can be split into two hoppers for positioning adjacent a wheel of the floor cleaning machine. The hoppers, split or not, can be located near the front of the machine such that the overall length of the floor cleaning machine need not be extended. A splitter can be positioned proximate the floor cleaning mechanism to drive debris into the split hoppers. The hoppers, split or not, can be coupled to a common lifting system that can pull the hoppers out from under a chassis of the floor cleaning machine and then upwards for positioning relative to a refuse container. Furthermore, the orientation of the hoppers can be controlled to position openings for the hoppers in a desired location to prevent spilling and facilitate emptying.

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.
