A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber and opening allows air, dust and debris to be drawn into the dust chamber during use. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber. The filter is preferably made of a non-woven material with a basis weight between about 20 and 70 gsm, and has a thickness less than about 1.0 mm.

A nozzle for a cleaner has a nozzle housing, and first and second rotation cleaning units arranged on a lower side of the nozzle housing and spaced apart from each other. Each of the first and second rotation cleaning units includes a rotation plate coupled to a mop. The nozzle includes a first driving device having a first driving motor to drive the first rotation cleaning unit and a second driving device having a second driving motor to drive the second rotation cleaning unit. Further, the nozzle has a water tank mounted on the nozzle housing to store water. The nozzle housing includes driving unit covers arranged to surround each of the driving devices. At least one of the driving unit covers includes a first protruding surface, and a second protruding surface positioned higher than the first protruding surface.

A surface cleaning apparatus has a cyclone and a dirt collection chamber wherein the dirt collection chamber has a dirt collection chamber portion which is located axially spaced from the cyclone chamber and the dirt collection chamber portion has a transverse section in a plane transverse to the longitudinal axis of the cyclone that is annular.

A nozzle for a cleaner has a nozzle housing including a nozzle base and a nozzle cover coupled to an upper side of nozzle base, the nozzle cover including a bottom wall recessed towards the nozzle base, a flow path forming portion positioned between the nozzle base and the nozzle cover, a connection tube positioned at a rear side of nozzle housing, a water tank positioned on the nozzle cover and a plurality of rotation cleaning units arranged on a bottom side of the nozzle base and spaced apart from each other in a lateral direction, each the plurality of rotation cleaning units including a rotation plate configured to be coupled to a mop.

A nozzle for a cleaner includes a nozzle housing including a suction flow path through which air containing dust can flow and a driving unit cover including a plurality of protruding surfaces, a first rotation cleaning unit and a second rotation cleaning unit disposed on a bottom side of the nozzle housing, each of the first rotation cleaning unit and the second rotation cleaning unit including a rotation plate designed to be coupled to a mop, rotation centers of the first rotation cleaning unit and the second rotation cleaning unit are eccentric with respect to a center of the driving unit cover, a driving device for driving the first rotation cleaning unit and the second rotation cleaning unit; and a water tank provided on the nozzle housing and for storing water to be supplied to the mops.

A surface cleaning apparatus has a surface cleaning head and an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion has upper portion laterally extending members. An above floor cleaning wand is removably receivable in air flow communication with the upper portion. The wand has wand laterally extending members, wherein, when the wand is received in air flow communication with the upper portion and the upper portion is in the storage position, the wand has a lower end and an upper end spaced from the lower end along a wand axis and the wand laterally extending members are positioned above the upper portion laterally extending members. A portable surface cleaning unit is removably mounted to the upper portion wherein, when the portable surface cleaning unit is mounted to the upper portion and the upper portion is in the storage position, the upper portion has lower mounting members which engage the upper portion laterally extending members and upper mounting members which engage the wand laterally extending members.

An upright surface cleaning apparatus is has a portable surface cleaning unit removably mounted to an upper portion that is pivotally mounted to a surface cleaning head. The surface cleaning apparatus is operable in a floor cleaning mode in which the portable surface cleaning unit is mounted to the upper portion and the above floor cleaning wand is inserted in an open upper end of the upper portion. The surface cleaning apparatus is also operable in an above floor cleaning mode in which the portable surface cleaning unit is mounted to the upper portion and the above floor cleaning wand is removed from the open upper end of the upper portion. When the surface cleaning apparatus is in the floor cleaning mode, the first mounting members of the portable surface cleaning unit engage the wand mounting members.

The present disclosure relates to an autonomous cleaning robot. The autonomous cleaning robot may include a main body (1), a cleaning assembly, a cleaning cloth and an obstacle-assisting wheel. The cleaning assembly is mounted on the main body (1). The cleaning assembly may include a first cleaning subassembly (2) removable and provided on the main body (1). The cleaning cloth is removable and provided on the first cleaning subassembly. The obstacle-assisting wheel is rotatably mounted on the cleaning assembly and protruding from the cleaning cloth.

A vacuum tool is configured to be removably coupled to a hose or wand of a vacuum. The vacuum tool comprises a first portion, a second portion, a flexible portion and a mechanical joint. The first portion and the second portion are connected by the flexible portion and coupled by the mechanical joint, so these portions are in fluid communication from various angles. And the mechanical joint comprises a detent and multiple recesses coupled to the detent. As a result, a user can use the vacuum tool in various situations more conveniently by bending the mechanical joint.
