Not sure if you know this but Coleman Hanna (Manufacturer of this and the Water Wizard) is actually based out of Texas. They are located at 5843 W .34th ST Houston Texas. I believe they do factory tours as well. So I guess if your ever in the area you can stop by and get a tour.
Car Wash Classics There’s also going to be a convention in San Antonio in 2020. It’s hosted by the International Carwash Association. Its called The Car Wash Show. Every manufacturer will be there and will have their machines up and running to demonstrate. You can also get a ton of car wash literature/merchandise. Go to carwash.org and there should be something on the website about the next show.
