I have.....
one like this, in all black. I have not used it in a while to answer your question. I do know that the squeegee leading edge can warp and tear if you store the machine with the upper and lower sections 90 degrees (normal operating position). Best to store these sections straight and lean the whole thing against something. The old and new squeegee blades were included when I got it. The solution foaming nozzle is easy to loose and new ones HARD to find. It half turns off and is located underneath behind and between the brushes.
I will venture to guess, the brush holders are worn and are not gripping the brushes tightly.
