  • the pressure hose 28 can also be removed from the accessory compartment 32, the end region 126 can be inserted into a recess 128 in the side wall 42 of the trough-shaped receptacle 26 of the base part 12, and then the storage tank 14 can be opened again the base part 12 are placed.
  • a flow connection is automatically established between the storage tank 14 and the pump 18.
  • the user can turn on the pump 18 so that cleaning fluid is pressurized.
  • the pressurized cleaning liquid can be directed by the user via the pressure hose 28 and the valve gun 30 at an object to be cleaned.
  • the user can switch off the pump 18 by means of the ON / OFF switch 130, pivot the first carrying handle 62 into the release position and remove the storage tank 14 from the base part 12 again in order to then switch the pressure hose 28 and the valve pistol 30 to be stowed in the accessory compartment 32. Finally, the user can then place the storage tank 14 back on the base part 12, pivot the first carrying handle 62 back into the carrying position and then move the first carrying handle 62 together with the second carrying handle 64 so far down in the direction of the base part 12 that the second handle 62 comes to rest on the upper side 36 of the storage tank 14, the second handle thus assumes its storage position, and the first handle 62 assumes its parking position.
