The present invention provides a pump, and a cleaning apparatus. The pump (10) comprises: a pump housing (14) having a pump chamber (12); an inlet (16) and an outlet (18) connected to the pump chamber; a motor (22); and an impeller (20). The motor comprises a stator and a rotor (26). The impeller is fixated to be connected to a rotational shaft to be synchronously rotated with the rotational shaft, always. Winding of the stator drags the rotor to be rotated in the fixed starting direction while a step of starting a synchronous motor. |
