High-pressure cleaning appliance

A high-pressure cleaning appliance, comprising a heatable heat exchanger for heating a fluid to be dispensed by the high-pressure cleaning appliance, a motor having a drive shaft that defines a drive axis, a pump unit for increasing the fluid pressure, a fan for generating a combustion air stream and having a fan housing, and a fuel pump for delivering a fuel for the heat exchanger, the pump unit, the fan and the fuel pump being located along the drive axis and being drivable by the drive shaft, and the high-pressure cleaning appliance comprising at least one securing device for securing the fuel pump on the fan housing on its side facing away from the motor, wherein the high-pressure cleaning appliance comprises a first securing device having at least one securing element and a securing element receptacle integrally formed on the fan housing and associated with the at least one securing element, and wherein the first securing device is transferable from an unsecured position, in which the fuel pump is coupleable to the drive shaft and releasable from it, to a secured position in which the at least one securing element is located in the securing element receptacle and secures the fuel pump to prevent it from being released from the drive shaft, and the first securing device is movable to the secured position by inserting the at least one securing element into the securing element receptacle.
