  • the high-pressure cleaning device has a device housing and a running gear which has at least three and particularly preferably at least four rolling elements which are intended to open a device supporting surface.
  • a particularly advantageous stability and advantageous handling can be achieved, in particular if the chassis has at least one rolling element which is pivotally mounted about a steering pivot axis and in particular if at least one axis is provided with steerable wheels.
  • a "pivot axis" is to be understood in particular a pivot axis about which the rolling elements can pivot in order to follow next to its rolling motion of a curved path can.
  • the steering pivot axis preferably has an angle between 80 ° and 100 ° and preferably of approximately 90 ° to a rolling axis and to a device supporting surface.
  • a "rolling element” is conceivable of various bodies which appear appropriate to a person skilled in the art, such as, for example, balls, rollers and / or particularly advantageously wheels which, in contrast to rollers, have a width which is smaller than their diameter.
  • the chassis has at least one rolling body, which protrudes laterally over a device bottom contour of the device housing and in particular on the device housing, in particular a projection thereof on a flat surface, whereby the stability can be further improved.
  • chassis is formed by a pedestal.
  • a “subset” should be understood in particular a unit which is at least partially disposed below the device housing and in particular a at least partially decoupled from the device housing support structure for receiving bearing forces, in particular a frame having.
  • the pedestal is advantageously formed by a separable from the device housing unit, in particular by a holding and unlocking unit is provided which serves to releasably connect the pedestal and the device housing , If necessary, then the Device housing separated from the base of an operator and thus a handle of the high-pressure cleaner can be used advantageously.
  • the pedestal preferably has a receiving area for the device housing.
  • a "receiving area” in this sense is to be understood in particular a recess into which the device housing can be used.
  • the pedestal on side cheeks and / or on its front side a cheek to form the receiving area, whereby this can be designed structurally simple advantageous.
  • the base can be produced in particular if it is at least partially manufactured in a shell construction, i. is formed at least from two composite shell parts, whereby in particular the receiving area can be made simple and particularly advantageous.
  • a system with a high-pressure cleaner and a spiral hose is advantageously designed in such a way that at the standing on a floor high-pressure cleaner with mounted spiral hose, this with its high pressure cleaning device end facing away from an unloaded position, vertically upwards to a distance of at least 2.5 m can be performed to the ground before a resultant within the spiral hose clamping force exceeds a weight of the high-pressure cleaner, so that can be particularly advantageously avoided that when working overhead the high-pressure cleaner is lifted undesirable from the ground.
  • FIG. 1 shows a high-pressure cleaning device with a device housing 10 in which an electric drive unit, not shown, a displacement machine for generating a working pressure and a device for regulating working pressure and water quantity are arranged, and with a base formed by a base 12, which is substantially below a Device floor is arranged and four formed by wheels rolling elements 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 which is intended 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 side cheeks 30, 32 and the front cheek 34 to form the receiving area 28.
  • a further cheek 52 is provided which has a recess 54 for a water connection 56 ( FIG. 4 ).
  • 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 designed as a high-pressure hose 36, 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.
