Abstract: A cleaning apparatus may include a cleaning unit that is kept from moving downwardly from a predetermined limit position. The apparatus body includes a positioning member that positions the cleaning unit at the limit position. The cleaning unit includes an intake nozzle that is arranged at a position separated from the surface to be cleaned by a predetermined gap, a cam member that holds the cleaning unit at the limit position, and an operation input unit that changes the limit position to a higher position by moving the cleaning unit upward by operating the cam member.

Abstract: An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

Abstract: A cleaning apparatus according to one or more embodiment may include a moving body configured to move on a surface in a moving direction; and a cleaning unit provided in the moving body and is configured to clean the surface to be cleaned. The cleaning unit may include: an intake nozzle; an intake unit configured to suction in objects, along with air, from the surface to be cleaned through the intake nozzle; a collection container configured to separate the objects that are suctioned in and collect the objects in an inside of the collection container; an air discharge duct configured to guide air suctioned in by the intake unit from an air outlet of the intake unit to an inside of the cleaning unit; and a cover member that covers at least the air discharge duct, and is configured to form an internal space with the air discharge duct.
