The invention is applicable to the field of fluid pumps, and provides a heating pump and a cleaning device. The heating pump comprises a shell, a heating device and an impeller, wherein a liquid inlet cavity, a connecting cavity and a liquid outlet cavity which are sequentially communicated are formed in the shell, the heating device is arranged in the liquid inlet cavity, and the impeller is arranged in the liquid outlet cavity. The impeller comprises an inlet end and an outlet end, the inlet end is communicated with the connecting cavity, and the outlet end is communicated with the liquid outlet cavity. According to the heating pump, the heating device and the impeller are arranged in different cavities, so that the high-temperature radiation influence of the heating device on the impeller and the pump shell is reduced, the situation that the impeller and the pump shell are aged too early is avoided, the use reliability of the heating pump is improved, and the service life of the heating pump is prolonged.
