Abstract: A water cleaner, including a housing, a filtering mechanism and a filtering unit. Two ends of the housing are respectively provided with an inlet and an outlet. The filtering mechanism is arranged in the housing. The sewage flows into the housing through the inlet and flows towards the filtering mechanism. The filtering mechanism is configured to filter the sewage to obtain clean water, which flows out of the housing through the outlet. The filtering unit is arranged at the inlet of the housing, and is configured to allow water remaining in the housing to be discharged and prevent dirt remaining in the housing from being discharged when the water cleaner stops sewage purification and is separated from the sewage.

Abstract: A suction pool cleaner, including a housing, an impeller, a driving member, a first baffle plate and a second baffle plate. The housing has a water inlet and a water outlet. The impeller is located in the housing between the inlet and the outlet. The driving member includes a main body and a drive shaft arranged thereon. The impeller is sleeved on the drive shaft, and the driving member drives the impeller to rotate around the drive shaft to generate a suction force. The first baffle plate is located in the housing between the impeller and the inlet, and an axis of the drive shaft passes through the first baffle plate. One end of the second baffle plate is connected to an end of the impeller near the main body, and the other end is adjacent to the main body.

Abstract: An underwater cleaning robot, including a main body provided with an accommodating chamber inside, a suction motor, and a roller brush assembly. A bottom of the main body is provided with a suction port. The suction motor is arranged in the chamber, and generates suction force to draw wastes into the chamber through the suction port. The roller brush assembly includes a roller brush motor arranged in the chamber, a connecting part, and a roller brush. The connecting part is arranged on the main body and is connected to the roller brush motor. The roller brush is detachably clamped with the connecting part. The roller brush motor drives the connecting part to rotate around an axis of the roller brush motor, so as to drive the roller brush to rotate synchronously to push the waste to the suction port.
