Abstract

A robotic floor cleaner includes a main body, which houses a propelling unit for moving the robotic floor cleaner on the floor and a control unit for controlling the operation of the propelling unit to move the robotic floor cleaner on the floor according to a predetermined steering mode, a daughter body detachably fastened to the main body and houses a vacuum cleaner unit for removing dust, and a handle assembly detachably connectable to the daughter body.

Claims

1. A robotic floor cleaner comprising:

a main body, said main body comprising a propelling unit for moving the robotic floor cleaner on the floor, and a control unit for controlling the operation of said propelling unit to move the robotic floor cleaner on the floor according to a predetermined steering mode;

a daughter body detachably fastened to said main body, said daughter body comprising a wind tunnel extending to a bottom side thereof, a dust collector, and a fan adapted to cause a vacuum in said wind tunnel to suck dust from the floor to said dust collector; and

a handle assembly connectable to said daughter body, the handle assembly comprising a base, two actuating members bilaterally supported on said base and transversely movable relative to each other, and two locking members respectively fastened to said actuating members and movable with said actuating members between a locking position where said locking members are engaged with a part of said daughter body to lock said handle assembly to said daughter body and an unlocking position where said locking members are disengaged from said daughter body for allowing separation of said handle assembly from said daughter body.
