A robot cleaner to perform cleaning without interruption of travel when passing over an obstacle. The robot cleaner includes a main body, and drive devices at left and right sides of the main body. Each drive device includes a main wheel to drive the main body, a drive motor to rotate the main wheel, a gear assembly to transmit power from the drive motor to the main wheel, a drive shaft to assist the main wheel in rotating by rotation power, and an auxiliary wheel connected to a distal end of the drive shaft so as to be located closer to the center of the main body than the main wheel. If the main wheel is lifted from a floor when passing over an obstacle during traveling, the auxiliary wheel protrudes downward to reach the floor, assisting the main body in traveling to escape from the obstacle.

A pick-up head system comprises a housing and a main fan connected in air suctioning relation to the housing for causing the interior of the housing to have a reduced internal air pressure. A secondary substantially continuously available source of low air pressure has an inlet connected in air suctioning relation to the housing. A valve is operatively mounted between the housing and the inlet of the source of low air pressure. A control mechanism is operatively connected to the valve and responsive to at least one operational condition in the pick-up head system. In a reduced-flow position, the air pressure in the housing is unaffected by the vacuum tank. In the increased-flow position, when the at least one operational condition passes a threshold, the vacuum tank decreases the air pressure in the housing, thus precluding the escape of dust and other fine particulate matter from the interior of the housing.

摘要:
The present disclosure is directed generally to waste water vessels with multiple valved chambers, and associated systems and methods. A method in accordance with a particular embodiment includes drawing waste water into a first chamber under vacuum while the first chamber and a second chamber have at least approximately the same internal pressure. The method further includes allowing the waste water to pass from the first chamber to the second chamber while the first chamber and a second chamber have at least approximately the same internal pressure, releasably sealing the first chamber from fluid communication with the second chamber, and simultaneously adding waste water to the first chamber and removing wastewater from the second chamber while the first chamber is sealed from fluid communication with the second chamber.
