Left to its own devices, your carpet hoards dirt, hair, grime, and used cars, eventually transforming into a full-fledged junkyard complete with angry raccoon tribes. Keep the outdoors out of your indoors with today's deal: for $45, you get three rooms' worth of all-natural carpet cleaning (up to 275 square feet, a $95 value) from Best Choice Carpet Cleaning, a green cleaners serving Sioux Falls and any area within 15 miles of the city limits. Act in haste and repent in fresh, clean leisure—you must redeem today's Groupon before December 31, 2010.

Best Choice's carpet cleaning uses an all-natural, residue-free formula to clean up filthy carpets. Its encapsulation cleaner coats any leftover dirt or particles in a quick-drying crystal that's easily removed with normal vacuuming, meaning that rooms dry in one to two hours instead of one to two fortnights. Choose three rooms (up to 275 square feet total, about the size of one 8'x9' and two 10'x10' bedrooms, or one huge, carpeted rave dance floor) and remove the furniture in preparation. Even with regular vacuuming, carpet can still manage to store up vast amounts of grime and filth, exactly like the members of KISS. Unlike aging rockers, however, it can easily be restored to a pristine state with today's deal.

New clients only. Best Choice will move furniture for an extra $10. Additional cleaning costs $0.32 per square foot. Stairs are $2 per step.
