A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.

Heatable high pressure cleaning appliance

A heatable high-pressure cleaning device () is provided with a fuel-operated heat exchanger () and a fuel tank () which has a tank upper section () with a closable filling opening () and a tank lower section () forming the base () of the fuel tank (). In order to develop the heatable high-pressure cleaning device () further in such a manner that it can be produced more inexpensively and have a longer service life, the tank upper section () can be connected to the tank lower section () in a materially joined manner via a join area () and the fuel tank () can be fillable with liquid fuel only up to beneath the join area () in a horizontal position of use of the high-pressure cleaning device ().

Heatable high-pressure cleaning device

A system for storing and dispensing a liquid cleaning additive for a high-pressure cleaning appliance has a device for storing the cleaning additive and a device for dispensing the cleaning additive in a controlled manner. In order to develop the system such that it is easier to handle, it is proposed that the storage device has an intermediate tank, which is fixedly held on the high-pressure cleaning appliance, and an independently handlable refill container for filling the intermediate tank, it being possible for liquid cleaning additive to be withdrawn in a controlled manner from said intermediate tank by means of the dispensing device, it being possible for the refill container to be secured on the high-pressure cleaning appliance and to be flow-connected to the intermediate tank, cleaning additive flowing automatically out of the refill container into the intermediate tank upon withdrawal of cleaning additive from the intermediate tank, in order to maintain a predetermined liquid level in the intermediate tank. A refill container for such a system and also a high-pressure cleaning appliance having such a system are also proposed.

System for storing and dispensing liquid cleaning additive for a high-pressure cleaning appliance

A cleaning apparatus, in particular a high-pressure cleaning apparatus, is provided, on which at least one fastening device for fastening the cleaning apparatus to a carrier is disposed. The at least one fastening device comprising at least one tensioning section on which a tensile force, which is directed at the carrier, acts when the cleaning apparatus is fastened to the carrier by means of a tensioning element. At least one retaining section is connected to the at least one tensioning section, for retaining the at least one fastening device on the cleaning apparatus. The at least one fastening device has at least one support section in order to be supported on the cleaning apparatus. The support section is connected to the at least one tensioning section by at least one connecting section, the at least one connecting section yielding if the tensile force exceeds a maximum permissible tensile force.
