Provided are a scrubber brush assembly and a vacuum cleaner having same. The scrubber brush assembly includes a roller brush body and a scraping sleeve. The roller brush body is rotatable around a first rotation center line and has a bristle (12) provided thereon. The scraping sleeve is rotatable around a second rotation center line noncoincident with the first rotation center line and sleeved over the roller brush body. The scraping sleeve has a scraping sleeve hole defined thereon. The bristle is adapted to be extended out of or retracted into the scraping sleeve hole in a wall thickness direction of the scraping sleeve.

A vacuum cleaner charging dock comprising a base and a bracket is provided. The bracket is arranged on one side of the base and is provided with a charging socket for charging a vacuum cleaner, while a positioning slot is arranged on another side of the base, the positioning slot is used for containing a floor brush of the vacuum cleaner, the positioning slot is provided with a plurality of convex teeth, which are used for rubbing with a rolling brush on the floor brush. The vacuum cleaner charging dock is provided with convex teeth, and the rolling brush of floor brush has deformation contact with the convex teeth. When the rolling brush starts to rotate, the convex teeth are easy to perform frictional rotation. Then dust and sewage on the rolling brush are shaken off into a positioning slot to complete the cleaning to the rolling brush, which is convenient and efficient.

The present disclosure provides a surface cleaning apparatus with a housing, a nozzle cover attached to the housing, a headlight, and a nozzle cover sensing mechanism. The nozzle cover sensing mechanism can determine whether the nozzle cover is present on the housing, and the headlight can accordingly be deactivated. Methods for operating the nozzle cover sensing mechanism are also disclosed.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

A floor treatment device may include a body portion comprising one or more pumps, one or more spray outlets, and one or more reservoir receptacles configured to receive one or more reservoirs. The one or more pumps are operable to be activated and direct liquids to the spray outlets. The device may include swappable heads, each comprising a body connector configured to mate with a head connector of the body portion. In an embodiment, the head connector may include a sensor system and a controller communicatively connected to the sensor system. When one of swappable heads is connected to the body portion, the sensor system is configured to detect the identity of the swappable heads connected, and the controller is configured to selectively activate, based on the identity of the swappable heads, at least one of the one or more pumps.

The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate at different velocities. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.

A robot cleaner includes a body to travel on a floor; an obstacle sensing unit to sense an obstacle approaching the body; an auxiliary cleaning unit pivotably mounted to a bottom of the body, to be extendable and retractable; and a control unit to control extension or retraction of the auxiliary cleaning unit based on a pivot angle formed by the auxiliary cleaning unit with respect to a travel direction of the body when the obstacle is sensed.
