A pump for sludge removal apparatus, a method of operating the pump, and a sludge removal apparatus including the pump are provided. The pump includes a pump housing having a pumping inlet at a front end and a pumping outlet at a rear end defining a rearwards direction; and a pumping nozzle positioned within the housing and oriented to direct fluid along the housing towards the rear end. The housing includes an inlet portion that decreases in cross-section from a front end to a rear end optionally a throat portion having a constant cross-sectional area positioned immediately adjacent the rear end of the inlet portion and an outlet portion that increases in cross-section from a front end to a rear end with the front end positioned immediately adjacent the throat portion if present, or immediately adjacent the rear end of the inlet portion if a throat portion is not present; wherein the pumping nozzle is positioned within the housing in front of the inlet portion of the pump housing. The pump can be positioned adjacent a rear end of a sludge removal apparatus and act to pump sludge away from the sludge removal apparatus.

The present disclosure relates to the field of smart home technologies, and proposes a base station and a cleaning robot system. The base station is configured to clean a cleaning system of a cleaning robot, and includes a base station body and a cleaning component. The base station body includes a cleaning groove, and the cleaning component is movably disposed on the base station body. The cleaning component includes a liquid outlet device, and cleaning liquid discharged by the liquid outlet device is configured to clean the cleaning system and enter the cleaning groove. After the cleaning component is positioned opposite to the cleaning system, the cleaning component moves, and the liquid outlet device moves along with the cleaning component. Then, the cleaning component can remove debris from the cleaning system. That is, the cleaning robot can realize automatic cleaning on the cleaning component.

A surface maintenance machine comprises a surface maintenance head assembly with attached surface maintenance tool for collecting debris/fluid using a fluid delivery/recovery system. Embodiments include an outlet nozzle configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. The outlet nozzle is fluidly connected to a cleaning fluid source which can vary the intensity of cleaning fluid exiting the outlet nozzle such that different intensities of the cleaning fluid correspond to the cleaning fluid being dispensed on different areas of the surface maintenance tool. Embodiments also include a second outlet nozzle, located opposite the first, which is configured to dispense cleaning fluid exiting the outlet nozzle on the surface maintenance tool. Further embodiments include a pump which can vary the intensity of cleaning fluid exiting the outlet nozzle in a cyclical manner and suspend the cleaning fluid from exiting the outlet nozzle.

A nozzle part and a robot cleaner including same are disclosed. A nozzle part according to various embodiments of the present invention comprises: a brush for collecting waste such as hair; and a removing member for removing the waste, such as hair, that is stuck to the brush. The removing member more quickly rotates than the brush in the same direction to remove the waste, such as hair, that is stuck to the brush. Therefore, the waste such as hair can be easily collected, removed and captured. Thus, user convenience can be improved.
