Cleaning apparatus

A cleaning apparatus, comprising:

• a hollow input shaft, which is connectable to a hydraulic pressure source, is accommodated in a first housing part, and has a fluid channel, wherein the fluid channel of the hollow input shaft has at least one lateral or axial input and at least one lateral output;
• at least one hollow output shaft, which is fluidically coupled to the hollow input shaft, is accommodated in a second housing part, and has a fluid channel, wherein the fluid channel of the at least one hollow output shaft has at least one lateral input and at least one lateral or axial output, wherein the hollow input shaft or the hollow output shaft is rotatably mounted around its longitudinal axis relative to the first or second housing part, respectively;
• a first chamber is arranged at least between an inner jacket of a sealing sleeve and the input of the hollow input shaft, the output of the hollow input shaft, or the input of the at least one hollow output shaft,
• wherein the sealing sleeve is secured in a positionally and rotationally fixed manner on the first or second housing part and encloses a part of the hollow input shaft or hollow output shaft, and
• wherein regions of the inner jacket of the sealing sleeve extending axially from the first chamber form a gap seal with an outer jacket of the hollow input shaft or with an outer jacket of the hollow output shaft.
