  • the high-pressure cleaner is also advantageously equipped with a spiral hose.
  • the spiral hose is particularly preferably designed in such a way that in standing on a floor high-pressure cleaner with mounted spiral hose, this with its end facing away from the device, starting from an unloaded position, vertically upwards along an axis perpendicular to the ground on a Distance from at least 2.5 m to the ground can be performed before a resultant within the spiral hose clamping force exceeds a weight of the high-pressure cleaner.
  • a system with a high-pressure cleaner and a spiral hose is advantageously designed in such a way that when standing on a floor high-pressure cleaner with mounted spiral hose, this with its end remote from the high-pressure cleaning device, starting from an unloaded position, can be guided vertically upwards to a distance of at least 2.5 m to the ground, before a resultant within the spiral hose clamping force exceeds a weight of the high-pressure cleaner, so that in particular advantageously avoided may cause the high pressure washer to be lifted off the ground undesirably when working overhead.
  • FIG. 1 shows a high-pressure cleaner with a device housing 10, in which an electric drive unit, not shown, a Displacement machine for generating a working pressure and means for regulating the working pressure and the amount of water are arranged, and with a base formed by a chassis 12, which is disposed substantially below a device housing bottom and four rolling elements formed by wheels 14, 16, 18, 20, which are intended to open a device support surface 22 ( FIG. 1 . 2 . 4 to 7 ).
  • the pedestal is wider than the device housing 10 is formed and the rolling elements 14, 16, 18, 20 protrude beyond a device bottom contour of the device housing 10 and the device housing 10 itself completely laterally.
  • the rolling elements 14, 16, 18, 20 are arranged on two transverse to a longitudinal direction of the chassis 12 extending bearing axes, wherein the front rolling elements 14, 20 are pivotally mounted about a steering pivot axis 24 which is perpendicular to a rolling axis of the rolling elements 14, 20.
  • the substructure forming the chassis 12 is formed by a unit which can be separated from the device housing 10 or is provided so that it can be removed by an operator from the device housing 10.
  • a holding and unlocking unit 26 is provided to releasably connect the pedestal and the device housing 10.
  • the holding and unlocking unit 26 has on a front side arranged cheek 34 of the pedestal a removable flap 48 and under the flap 48 a snap closure forming unlocking element 50 ( FIG. 7 ), while on the side facing away from the front side not shown in detail, with the device housing 10 corresponding interlocking elements for securing the device housing 10 are provided on the pedestal. If the unlocking element 50 is released, the device housing 10 can be guided past the interlocking elements arranged on the pedestal and separated from the pedestal.
  • the base made of plastic in a shell construction has a receptacle 28 formed by a recess for the device housing 10, which is adapted to the contour of the device housing 10, so that it can be received in the same form-fitting ( FIGS. 6 and 7 ).
  • the base has to form the receiving area 28 side cheeks 30, 32 and the arranged on the front cheek 34.

  • the device housing 10 is inserted into the receiving area 28, it is delimited laterally by the cheeks 30, 32, 34, 52, so that the device housing 10 is fixed in the receiving area 28 in a form-fitting manner, in particular in the direction of travel and transversely to the direction of travel, parallel to the device supporting surface 22. If the device housing 10 is removed from the receiving area 28 of the pedestal, this can advantageously be transported by means of a strap handle 58 arranged on an upper side of the device housing 10 ( FIG. 3 ).
  • the high-pressure hose device comprises a spiral hose 36 designed as a high-pressure hose, which is designed like a helical compression spring and is provided for elastic deformation. In the unloaded state spiral spirals of the spiral tube 36 are almost directly adjacent to each other and the spiral turns are arranged substantially coaxially about an axis 62 oriented substantially perpendicular to the device support surface 22 axis ( FIG. 4 ).
  • a distance between the spiral turns with respect to the unloaded state can increase by a multiple, so that a distance between a high pressure gun 64 arranged at an end of the spiral hose 36 facing away from the connection 60 can be increased by a multiple.
  • FIG. 5 a distance between a high pressure gun 64 arranged at an end of the spiral hose 36 facing away from the connection 60 can be increased by a multiple.
  • an operator must apply an equivalent force, which is dependent upon the stiffness of the spiral tube 36.
  • the spiral tube 36 is permanently brought into its shape during its production under the action of heat, so that in a later operational use of this principle by internal clamping force always after cancellation of a force back into his in FIG. 4 resets the displayed basic position.
  • a holding device 66 for the high-pressure gun 64 is arranged on a side wall of the device housing 10, as shown in FIG FIG.
  • the high-pressure gun 64 can be inserted and secured with its jet pipe 68, so that the High-pressure gun 64 and the spiral tube 36 may remain in a secure position during transport on the device housing 10 and removal of the spiral tube 36 and the high-pressure gun 64 can be avoided.
  • a holding and / or storage device is provided specifically for the spiral hose 36 on the device housing 10, in particular on its upper side.
  • a particularly favorable resilience is achieved in spiral form, i. that as a guideline with 5 m effective hose length 2.5 m working length can be achieved without causing the resilience of the spiral hose 36 is permanently damaged.
  • the system with the high-pressure cleaner and the spiral hose 36 is designed in such a way that in the standing on a floor high-pressure cleaner with mounted spiral hose 36, this with its high pressure cleaning device remote end, starting from an unloaded position, vertically upwards along the axis 62 a distance of at least 2.5 m to the ground can be performed before a resultant within the spiral tube 36 clamping force exceeds a weight of the high-pressure cleaner, so that in particular can be advantageously avoided that when working overhead the high-pressure cleaner is lifted undesirable from the ground ,
