I recently went through three different Wesumats to evaluate the washes for a prospective buyer. All three of these are owned by the same person, who has a well deserved reputation for poor maintenance. So I expected some issues. There were a couple of things though that seemed to not be maintenance related. The top brush had a hard time reaching the far right and left sides of the windshield. The washes always left noticeable spots due to poor rinsing. And they bent my antenna forward about a 30 degree angle. What do you owners find? If you have seen these issues and corrected them, how did you do that? The next day I went through a Broadway friction machine (you see them at car dealerships mostly) and got a surprisingly good quality wash from a machine costing half of the Wesumat.
