Just went through the best week since owning my wash. My auto kicked butt. People were amazed at the wash quality. Then I got a call from a lady who said her van didn’t get cleaned well. Next day another call from a disgruntled customer. What is going on? The first was from a lady with an extended height Sprinter with an AC unit on top. And it was also an extra long one. My auto will wash vans up to 8’-8” tall. This would push the envelope. Stood there watching with my hand on the emergency stop button. I thought it did a good job but noticed it did not do the rear well. The van was too long for the side brushes to get the rear and it had a camera mounted on top so the driver could see the rear. The amp sensing technology made the top brush go past more, so the rear didn’t get as clean as normal. The other vehicle was a Mini Cooper. They are basically golf carts that are street legal and this one had not been cleaned in a long time. We get this a lot as many are only here for the winter and leave the car just parked outside for the hot brutal summer. Rewashed both and got them clean but I found it odd that I had issues with the biggest and the smallest things out there.
