Abstract: A tipping method for a tipping arrangement which includes a first element (1) and a second element (2), arranged between a moveable base unit (4) and a rotatable container (3). The container (3) is rotated by moving the second element (2) along a first track (7) on the first element (1). The second element (2) is moved along the track (7) by rotating the second element (2) relative to the first element (1). A number of engaging parts (9, 10) may be arranged on the tracks (7, 8) of the elements (1, 2), respectively. An interlocking arrangement may be arranged between the first element (1) and the second element (2) to secure the second element (2) in a starting position. A movable unit includes the tipping arrangement and a section unit, with the container (3) locked in a vertical position by a locking arrangement.

Abstract: A squeegee assembly includes a front blade, a rear blade, and a support for mounting the blades. The front blade includes an outer surface, an inner surface, and a floor engaging edge. The rear blade includes an outer surface, an inner surface facing the inner surface of the front blade, and a wiping edge. The support includes a vacuum source port and a suction port. The rear blade has a curvature between opposing first and second ends of the rear blade that defines at least one rearmost point. At least the suction port is offset from a line of the support that extends through the at least one rearmost point parallel to a forward direction of travel of the squeegee assembly.

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 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.

Abstract: The invention relates to a method and system for controlling an engine (552) in a sweeper-scrubber. An electrical system alternator (554) provides power to at least one cleaning function (576, 578, 580) of a self-propelled hybrid vehicle and to driven wheels. The operational load is monitored, and the running state of an internal combustion engine (552) is controlled based on the monitored operational load. A threshold charge, of an electrical system battery pack (556) is maintained.

Abstract: A method and a system for controlling the charging and discharging of one or more battery packs (8) connected to a power source (7) or an apparatus (9) driven by the battery packs. The battery pack (8) comprises a number of battery cells connected to two or more terminals for establishing an electrical connection with the power source or the apparatus. The electronic system (2) for controlling the charging of the battery pack (8) and the electronic system (6) for controlling the operation of the apparatus (9) are integrated into the battery pack (8). The battery pack (8) comprises a communications interface for communicating with other battery packs (8) and generates a charging and discharging pool, where the most effective battery pack (8) to charge or discharge is charged and discharged first.
