The Evolution Dog Wash is designed to be familiar to the user, along the lines of a self-serve car wash. Once you insert payment, the timer allows you to use the time you’ve paid for in any way that you choose. You can switch back and forth from the selections or spend all of your time on one, the choice is yours. All the products are infused into the water stream, allowing for most dogs to be washed in a matter of a few minutes.
