If you see this contraption coming at you, don't be alarmed. It's here to help, not hurt.
"As you can see, my car needs washing and I wanted to know what that was anyway," said Lorraine Riley-James, Chicago.
This little rocket on wheels, known as "Geowash," is a mobile car wash. All the tools are tucked inside for easy access and portability.
"We take that machine and park it behind any car that we're going to wash. The unit has a hose that's 12-feet long. That hose can go around the car without moving the car," said Raja Abderrahim, Geowash.
Raja Abderrahim says the Geowash method only uses about 1 gallon of water per car -- and the no foam detergent used is also eco-friendly.
"The product we use is a sustainable product, that's how we clean the car. It does not harm the environment," Abderrahim said.
On this day, Geowash is operating in the parking lot of the Dominick's in Oak Park as part of a charity fundraiser. Customers applaud the eco-benefits, but also say the convenience of getting a hand car wash while they shopped is a huge plus.
"When we pulled up just to do our grocery shopping, obviously I wasn't thinking of getting my car washed in the parking lot," said Rence Kretchmar. "Just turned out to be extremely convenient to have it done, so I thought, why not?"
Geowash operates in the parking lots of hospitals, golf courses, casinos, even some apartment buildings. You can even order a car wash online.
