Kärcher Wheel Rim Washing Brush

I bought this brush together with the karcher 5,700 and unlike the pressure washer itself, which I am very satisfied with, this is really not what I expected. I assumed that the water would spray out of the brush in all directions under high pressure, or at least that water would actually come out in all directions like the Nilfisk wheel cleaner, only drips through this under some water. And really dripping, it would take at least 10 minutes to fill a bucket. If you want to do the top of your rim, you have to do this without the help of some water to drain the dirt. There are indeed holes on all sides but no matter how you hold the brush, it runs out along the bottom. The delivery itself was fast and correct, but this kärcher product is worth nothing in my eyes. Because this is at the end of your lance and you get no help from the pressure washer, you have to scrub and push very hard yourself, which is very inconvenient because you can't hold the brush directly yourself. An ordinary manual wheel brush, with some wheel cleaner works many times easier and is cheaper. Very sorry.
