Not bad but I expected more ... 1

Accustomed to washing in specialized stations, I decided to buy a small karcher Gardena and this brush. I expected better. The body of the brush is very thick, it can often touch the body if one is not careful. Brush hairs are shorter and more flexible than I thought. We must therefore rely more on well-remove grime on bodywork. Otherwise washes pellets, I have not even tried. I preferred to use the foam gun comes with Karcher and special shampoo Meguiar's.
A good point, the valve on the handle to close or not the water supply.
