A surface cleaning apparatus comprises an air treatment chamber, a pre-motor filter and a suction motor. The suction motor and the pre-motor filter are laterally spaced from the air treatment chamber. When the surface cleaning apparatus is positioned on a horizontal surface with the upper end of the air treatment chamber above the lower end of the air treatment chamber, the pre-motor filter is positioned at a higher elevation than the suction motor.

A self-propelled, dust-collecting robot includes a main-body part including a dust collection box, and a first battery pack, which has a case, at least one battery cell in the case, a control circuit board having a controller mounted in the case, and a discharge terminal. The main body part includes a first battery pack mount having a connector to which the first battery pack is removably connectable. The first battery pack is configured for use in an electric power tool.

A surface cleaning apparatus having an upright assembly, a power source, and a coiled electrical cable. The upright assembly including a frame and a telescoping handle at last partially extending from the frame and movable between an extended position and a contracted position. The coiled electrical cable being provided within a portion of the telescoping handle and configured to uncoil or coil when the telescoping handle is moved between the extended position and the contracted position.

A surface cleaning apparatus having a fluid delivery system and a fluid recovery system is provided with a housing including an upright body and a base coupled with the upright body. Cleaning fluid and electrical wiring can be routed between the upright body and the base via a yoked spine section of the upright body.

A touchless cleaning assembly for cleaning a room in a touch-less manner includes a cabinet is recessed into a wall of a room. A plurality of hose reels is positioned in the cabinet and each of the hose reels includes a hose that is drawable outwardly from the cabinet for spraying a fluid for cleaning surfaces in the room, for blowing air to dry the surfaces and to vacuum the surfaces. An air compressor is positioned within the cabinet to direct compressed air into a respective hose reel to dry the surfaces. A vacuum is positioned within the cabinet to supply vacuum pressure to the a respective hose reel for suctionally removing the fluid from a floor of the room.

A surface cleaning apparatus has a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber. The cyclone chamber has a sidewall extending from a first end to an axially opposed second end. A dirt outlet communicating with the dirt collection chamber is provided in the sidewall at a location intermediate the first and second ends of the cyclone chamber.

The present disclosure discloses a hand-push leaf suction machine with an automatic outage function for toppling which includes a housing provided with an air duct, a fan fixedly arranged in the housing, a dust collecting box, ground wheels arranged on two sides of the housing and supported on ground, auxiliary wheels arranged on two sides of the housing and supported on the ground, and a push handle arranged at a rear end of the housing.

In a vacuum cleaner electric blower is driven by power supplied by a secondary battery. A dust-collector is configured to catch and collect dust and dirt sucked by driving the electric blower. A detector is configured to detect a remaining amount of the secondary battery. A controller is configured to control suction force of the electric blower. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is equal to or less than a predetermined value, the controller sets the parameter to reduce the suction force of the electric blower for the next cleaning. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is not equal to or less than the predetermined value, the controller sets the parameter to increase the suction force of the electric blower for the next cleaning.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every ½ cycle of the alternating-current voltage.
