The present invention discloses a separator, including a top plate, a bottom plate, and a plurality of grid bars, wherein both the top plate and the bottom plate are circular in shape, and the diameter of the top plate is less than that of the bottom plate; the separator has a motor connection portion, and a center of the motor connection portion coincides with a rotation center of the separator; and the plurality of grid bars are circumferentially spaced between the top plate and the bottom plate. The present invention further discloses a cleaner with the above separator. The separator has large air inhaling force, and makes a drastic change to a speed of inhaled garbage. When the initial speed of the separator is low, it is not easy to inhale garbage. This improves a garbage separation effect without affecting the service life of a filter element.

A self-propelled object-gathering apparatus includes a chassis, a drive system coupled to the chassis and configured to traverse the apparatus over a surface, and a receptacle coupled to the chassis. The apparatus also includes a sweep assembly coupled to the chassis and rotatable with respect to the chassis. The sweep assembly is configured to transfer objects from the surface into the receptacle by mechanical action on the objects, and without the use of negative pressure or vacuum suction acting on the objects during the transfer, in response to rotation of the sweep assembly.

A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.

A docking station for a robotic vacuum cleaner may include a suction motor, a collection bin, and a filter system fluidly coupled to the suction motor. The suction motor may be configured to suction debris from a dust cup of the robotic vacuum cleaner. The filter system may include a filter medium to collect debris suctioned from the dust cup, a compactor configured to urge a first portion of the filter medium towards a second portion of the filter medium such that a closed bag can be formed, and a conveyor configured to urge the closed bag into the collection bin.

The present disclosure relates to a water tank structure and a vacuum cleaner. The water tank structure includes a tank body and a tank cover assembly. The tank body has an accommodation cavity therein, and an end of the tank body is formed with an opening in communication with the accommodation cavity. The tank cover assembly includes a cover body and at least one flow divider, and the cover body is disposed at an end of the tank body proximate to the opening. The flow divider is in communication with the cover body and the accommodation cavity. The flow divider is configured to divide a fluid stream flowing therethrough into a plurality of fluid streams formed into pairs having paired kinetic energies carried thereby and paired opposing flow directions, such that the kinetic energies of the pairs of fluid streams cancel out.
