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.

A vacuum cleaner including a cleaner head defining a suction chamber and having an agitator arranged to be rotated by an agitator motor, a dirt separator, a vacuum motor arranged to draw air into the suction chamber and then into the dirt separator, and a controller. The controller is configured to monitor the electrical load of the agitator motor, compare the magnitude of the electrical load to a threshold, and selectively adjust the electrical power delivered to the vacuum motor. The controller is configured either to increase the electrical power delivered to the vacuum motor to a predetermined upper power level if the electrical load is greater than the threshold, or to decrease the electrical power delivered to the vacuum motor to a predetermined lower power level if the electrical load is smaller than the threshold.

A cleaner head for a cleaning appliance, the cleaner head comprising: a housing defining a suction chamber; and a sole plate defining a downwardly-directed opening through which dirt can enter the suction chamber. The cleaner head further comprises a hollow deformable seal extending from a rear portion of the housing, the hollow deformable seal having a width at least equal to a width of the opening in the sole plate, and having a lower sealing surface that extends in a downward and rearward direction from a rear edge of the housing such that, in use, the hollow deformable seal is biased against and conforms to a surface being cleaned in order to maintain a seal between the cleaner head and the surface being cleaned.

A cleaner head is provided. The cleaner head includes: a nozzle; a case disposed close to an inlet of the nozzle; and a brush rotatably disposed in the case, wherein the case includes an air passage groove disposed in an outer side surface of the case and having a passage formed for the air to flow from an edge region of the case toward a surface to-be-cleaned.

The present invention provides a cleaner including a cleaner main body having a controller, a support member detachably coupled to a module mounting portion of the cleaner main body, and a mop module rotatably supported on the support member, wherein the mop module includes a rotating rod configured to be rotatable in at least one direction by being interlocked with a rotation driving portion provided in the module mounting portion when the supporting member is mounted on the module mounting portion, and a mop member formed to surround an outer circumference of the rotating rod so as to mop the floor in response to the rotation of the rotating rod.

A cleaning equipment is disclosed, which includes a housing, a moving assembly, a cleaning assembly and a cliff sensor, the cliff sensor being arranged on the housing, the moving assembly or the cleaning assembly; the cleaning assembly includes at least one first cleaning sub-assembly which includes an installing part, a first component and at least one second component; the first component and the second component extend outwards and rotate along with rotation of the installing part so as to stir dirt on the surface to be cleaned; the first component passes through the gap between the housing and the surface to be cleaned while rotating, while the second component does not pass through the gap while rotating. The cleaning equipment lowers frequency of blocking the cliff sensor from transmitting and receiving signal art, and improves detecting accuracy of the cliff sensor.

A robotic cleaner may include an air inlet, a suction motor, the suction motor being fluidly coupled to the air inlet, and a first primary side brush configured to rotate about a first primary side brush rotation axis. The first primary side brush rotation axis may extend transverse to a surface to be cleaned at a first non-perpendicular angle.

An agitator and a robot cleaner including an agitator. The agitator includes a body configured to be rotated, a plurality of couplers formed at the body and arranged to be spaced apart from each other by a predetermined distance, and a first member and a second member coupled to any one of the couplers and configured to contact a surface to be cleaned during rotation of the body. The first member and the second member extend different lengths from the body in a radial direction.

This invention relates to a dirt-collection chamber (10) for a vacuum cleaner, and in particular a dirt-collection chamber (10) which is removable whereby the collected dirt can easily be disposed of. The dirt-collection chamber (10) has an air inlet (22) and an air outlet (62), a filter (60) between the air inlet (22) and the air outlet (62), and a disposal opening with an openable cover (16). The dirt-collection chamber (10) has a dirt-removal panel (40) in the chamber which is movable towards and away from the disposal opening to assist in the disposal of collected dirt and debris.

A robotic cleaning apparatus can include a body and at least one antenna extending from a periphery of the body. The at least one antenna can be configured to rotate about an axis that extends substantially parallel to a surface to be cleaned.
