A pump and a cleaning apparatus are provided. The pump (10) includes a pump housing (14) having a pump chamber (12), an inlet (16) and an outlet (18) in communication with the pump chamber, a motor(22), and an impeller (20). The motor includes a stator and a rotor (26). The impeller is fixedly connected to a shaft of the rotor so as to always synchronously rotate along with the rotary shaft. The stator windings drag the rotor to rotate only in a fixed starting direction during a starting phase of the synchronous motor. |
