Though often standoffish and occasionally bent on destroying all of mankind, robots are surprisingly helpful when it comes to bathing automobiles. Strengthen the bond between man and machine with today’s Groupon: for $11, you get two Ultimate car washes at Surf Thru Express (a $24 value).

Surf Thru Express's speedy, automated onslaught of hoses, soaps, and delicate fabrics makes quick work of car filth in a WaterSavers-certified facility dominated by Ecolab products. For starters, the Ultimate wash unleashes a waterfall of Blue Coral triple foam to eliminate spots and wash away debris. Rain-X, the next best thing to real rain, keeps wheels and surfaces protected from the elements, and a coating of Black Magic tire shine douses road-weary tires with the same enchanting color you get by stuffing a rainbow in a blender. After WipeOut clear-coat shine adds a layer of sparkle, a spot-free rinse and power dry finish the exterior cleansing, and an air freshener and a free vacuuming ensure the insides stay fresh and especially sniffable. To guard against unexpected dust storms or pudding showers, the Ultimate wash includes a four-day guarantee to keep autos at the peak of their beauty.

Extremely lowered vehicles may not be able to pass through the car wash.
