- the assignment made by the user of the object captured by camera 60, which is to be cleaned, to the new object is stored in memory element 52, so that when the object to be cleaned is captured again by camera 60, the now stored assignment can be read by control device 50 can be carried out automatically.
- the memory content of the memory element 62 can be updated and supplemented in the same way as a software program in the control device 50 .
- the control device 50 can be connected to an external data processing device, for example to a server, a computer network (cloud), a smartphone or a tablet computer.
- an external data processing device for example to a server, a computer network (cloud), a smartphone or a tablet computer.
- This makes it possible not only to store object information for a large number of objects together with corresponding control parameters for controlling the high-pressure cleaning device in the storage element 62 at the manufacturer of the spray gun 12, but also to store further object information and control parameters in the storage element 62 at a later point in time by Connection to the external data processing device is established.
- the software program that is used to process the object information provided by the object detection device 50 in particular pattern recognition methods, can be updated.
- the detection of the object to be cleaned by means of the object detection device 58, in particular by means of the camera 60, has the advantage that the object to be cleaned can be cleaned as optimally as possible without the user having to have in-depth knowledge.
- the object to be cleaned is assigned to an object, with control parameters for optimal cleaning of this object being stored in memory element 62 and can be output by the control device 50 to the high-pressure cleaning device. This allows the operation of the high-pressure cleaning device to be adjusted in a simple manner in such a way that the object to be cleaned can be cleaned as optimally as possible.
