A robotic dust collector includes a suction member having a suction inlet and travels on a cleaning target surface. The robotic dust collector includes a guide member, a support part, and a biasing member. The guide member is disposed at the suction inlet and has a blade part facing the cleaning target surface. The support part supports the guide member in such a manner that allows the guide member to pivot about a pivot axis so as to allow the blade part to move in an up-down direction. The biasing member is configured to exert biasing force on at least a part of the blade part.

Robotic dust collector

A rotary brush is easily attachable to and detachable from a body with less separation from the body during cleaning. A rotary brush attachable to a driving shaft rotatable about a rotation axis and including a protrusion includes a brush, a base to which the brush is attached, and a locking member that comes in contact with the base and the driving shaft to lock the base to the driving shaft.

Rotary brush and robotic dust collector

A robotic dust collector includes: a cover plate that closes an opening of a housing; a first hinge member connected to the cover plate and having an insertion space; an elastic member disposed in the insertion space; and a second hinge member. The second hinge member includes a shaft part that is inserted in the insertion space and supports the elastic member. The second hinge member further includes a fixture part fixed to at least a part of the housing. The second hinge member supports the first hinge member in a manner that allows the first hinge member to rotate about a rotation axis.

A robotic vacuum () includes a main body () having a suction port () in a bottom surface (B) thereof; a storage unit () housed in the main body and configured to store dust and debris suctioned in via the suction port (); and at least one wheel () that supports the main body (). The main body () has a width Wb in a first direction that is parallel to a rotational axis (AX) of the wheel (), the storage unit () has a width Ws in the first direction, the main body () has a height Hb in a second direction that is perpendicular to the rotational axis (AX) and perpendicular to the first direction, and the storage unit () has a height Hs in the second direction. The width Wb is 470-600 mm, and the condition 0.5&#xd7;Wb&#x2264;Ws&#x2264;0.7&#xd7;Wb is satisfied.
