description A motor pump unit for a high-pressure cleaning apparatus has an electric motor and a pump. The electric motor has a motor housing that is surrounded by a cooling housing with an annular space having an annular space inlet and an annular space outlet formed therebetween. The pump has a suction inlet connected to the annular space outlet and a pressure outlet. The liquid to be transported by the pump can be supplied to the annular space inlet. The cooling housing, on its inside, has at least one flow guide rib for guiding the liquid within the annular space. In order to ensure that no liquid can leak out of the annular space even in the long term, the at least one flow guide rib is spaced-apart from the motor housing.
