The point deduction, there is the fact that the threads consist only of plastic, which then turns are no longer used once and even caused mechanically claimable. Because, unfortunately, the Kärcher 7.800 T400 ecologic even plastic is installed, a combination of plastic is - plastic constructively well certainly the better choice - which, incidentally, led to the high-pressure cleaner and the devaluation. The real problem is that of relatively narrow and long filter now rigid vertically projecting from the device body away in the middle of the room and true to Murphys Law - one remains now on this case under warranty depend someday, or the connected hose is now an additional leverage gets on the plastic connector on the machine, so that the plastic threads on the device body is now still delivered an additional mechanical loads. In plastic can not long go well, the - so that there are now two options, either use an elbow between the equipment and filter, or do not connect the filter directly to the machine, but use with additional connectors in the hose. It would be desirable have been here when the high-pressure cleaner, a filter in the unit would have been in there with the same, or would be provided a flexible connection. The filter could have been the same can provide a suitable angle connector, which is rotatably mounted, which would have been a thoughtful Kärcher solution with 5 stars.
