Abstract: A bumper system is disclosed. The bumper includes a support having one or more first members. The bumper further includes a bumper having one or more second members. The bumper being maintainable by the support in a rest position with respect to the support due to magnetic attraction between the one or more first members and the one or more second members when no force is applied to the bumper. The bumper is dislodgeable from the rest position towards the support when a force is applied to the bumper. When the force is removed from the bumper. the magnetic attraction between the one or more first members and the one or more second members returns the bumper to the rest position. The bumper system further includes one or more sensors mounted to either the support or the bumper for detecting dislodgement of the bumper from the rest position. A device including the bumper system is also disclosed.

Abstract: A noise suppressed vacuum motor assembly (100) comprising: an inner chamber housing (3) having at least one inlet opening (3A) and at least one outlet opening (3B); and a vacuum motor (1) located within the inner chamber housing, with a clearance space (102) provided around the vacuum motor, the vacuum motor, when in use, drawing an airflow through the inner chamber housing from the inlet opening(s) and through the clearance space before exiting through the outlet opening, such that a degree of laminar flow is induced in the airflow when passing through the clearance space.

Abstract: A floor mopping system (3) for an autonomous cleaning apparatus (1)65), comprising a mop roller assembly (5) including a mop roller (9) and a drive mechanism (19) for rotatably driving the mop roller about a longitudinal axis thereof, wherein the mop roller assembly is supported on a suspension assembly (63) comprising an adaptive suspension mechanism (65) for providing at least 3 degrees of movement for the mop roller assembly.

Abstract: The present disclosure relates to a system for performing a designated cleaning task. The system comprises a plurality of cleaning apparatus, and at least one of the plurality of cleaning apparatus is communicatively connected with a processor unit, wherein the processor unit comprises a hierarchy generation module for determining a hierarchy state of each of the registered cleaning apparatus; a task planning module for generating a cleaning operation plan based on the hierarchy state assigned to each of the registered cleaning apparatus; and a task execution module for transmitting a command to execute the cleaning operation plan. The present disclosure also relates to a cleaning apparatus for use with the cooperative cleaning system. The present disclosure also relates to a system for performing a designated task using a plurality of task specific devices by generating device-specific control command for each of the devices based on a high-level control command.
