Abstract: 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.

Abstract: 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.

Abstract: A robotic vacuum (1) includes a main body (2) having a suction port (15) in a bottom surface (2B) thereof; a storage unit (6) housed in the main body and configured to store dust and debris suctioned in via the suction port (15); and at least one wheel (9) that supports the main body (2). The main body (2) has a width Wb in a first direction that is parallel to a rotational axis (AX) of the wheel (9), the storage unit (6) has a width Ws in the first direction, the main body (2) 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 (6) has a height Hs in the second direction. The width Wb is 470-600 mm, and the condition 0.5×Wb≤Ws≤0.7×Wb is satisfied.
