Abstract: A compact motor housing for housing a motor and a blower of a cleaning device and with integrated air outlet silencing. The motor housing encloses a flow passage between a flow inlet and outlet. The housing has a blower chamber fluidically connected to the flow inlet, and via first and second outlet openings also fluidically connected to at least two parallel, preferably similar, silencer ducts each being arranged in an area limited by an angle of less than 90°, seen in a view parallel with the blower and motor axis. The silencer ducts each have at least one wallbetween the blower chamber and the external wall of the motor housing for causing at least one flow direction bend, so as to provide a noise attenuating effect. The areas occupied by the at least two silencer ducts are non-overlapping, seen in a view parallel with the blower and motor axis. With a circular blower chamber, a compact box shaped motor housing can be provided with corner volumes available for silencer ducts.

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: The invention relates to a cleaning machine (1) comprising a housing (10) and at least one hingeable element (20), as well as to the hingeable element (20) itself. The hingeable element (20) is detachably attachable to said housing via a hinge structure comprising at least two pairs of magnetizable or magnetic member surfaces (H1, E1; H2, E2). At least one surface in each pair exhibits a magnetic force for engagement with the other surface in said pair. A first member surface (E1; E2) in each of said pairs is supported by said hingeable element (20) and a second member surface (H1; H2) in each of said pairs is supported by said housing (10). When said hingeable element (20) is attached to said housing (10), said magnetic force is extending in a direction substantially in parallel with a magnetic centre axis (Am) extending between each first member surface (E1; E2). This provides a sufficient attachment force in the hinge structure both to allow the hingeable element (20) to stay attached to the housing during use, as well as to allow the hingeable element (20) to become detached easily from the housing (10), thus to function as a “break away”.
