A motor module includes a motor, a fan, and a casing accommodating the motor and the fan therein. The casing includes a tubular main body portion, an intake port, an exhaust port, a motor disposing unit, a flow passage, and a partition unit. The flow passage includes a fan accommodating unit, a first muffling chamber that communicates with the fan accommodating unit via a first communication path, and a second muffling chamber that communicates with the first muffling chamber via a second communication path. In addition, the partition unit includes an inner partition unit that partitions the motor disposing unit and the first muffling chamber. The first muffling chamber communicates with the motor disposing unit via a cutout portion in the inner partition unit.

A lid for a refuse container is moveable between a closed position in which the lid overlies an open upper end of the refuse container and an open position in which the refuse container may be emptied. The lid has an openable port operable between a closed position in which the lid closes the upper end of the refuse container and an open position in which a dirt collection region of an air treatment member of a surface cleaning apparatus is positioned in the port.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arraigned to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.
