Merry Maids' hyperefficient duos of dusters clean more than 300,000 residences each month in North America. Unleashed on the interior wilderness of an unkempt abode, the Merry Maids' voracious vacuums hunt down and devour dust dodos, paper-scrap porcupines, and other clutter-causing prey. Then, armed with nuclear-powered sponges and scum-seeking lasers, the militant maids scour countertops and tile grout with the single-minded meticulousness of a pilot scraping Dubble Bubble off his plane's instrument panel. No floor, whether wood, linoleum, marble, granite, or lentil, is too much for these smiling scourers, who have seen and conquered it all before.
