My wash is a 4 x 2, four self serve, two touchless automatics. I currently have their original fixed oval system. I recently purchased the Super Wash and the previous owner did a very good job maintaining the existing equipment, but never added any upgrades. I have other self serve locations so Superwash will not let me maintain the franchise. I am considering purchasing their upgraded touchless automatic system or ripping that out and going with a brand that will fit in that space. I do not know the size, but I will measure it tomorrow and get back to you. Thank you for your help.
