Household grime, if left unchecked, will inevitably develop into miniature civilizations whose complex network of treaties erupts into a devastating house-wide reenactment of World War I. Today’s Groupon spares you the trouble of tripping over tiny trenches: for $55, you get cleaning services for four rooms from Merry Maids of Memphis (a $110 value).

Merry Maids' hyperefficient dusters clean more than 300,000 residences each month in North America. Unleashed on the interior wilderness of an unkempt abode, the cleaning commando's voracious vacuum hunts down and devours dust dodos, paper-scrap porcupines, and other clutter-causing prey. Then, armed with nuclear-powered sponges and scum-seeking lasers, the militant maid scours countertops and tile grout with the meticulousness of a pilot scraping Dubble Bubble off his plane's instrument panel.

Additional rooms can be purchased at time of service for $10 per room.
