A dirty carpet is like a guilty conscience—it's always nagging you from the background, and it prevents you from eating off the floor in peace. Expunge lingering crud from your rug with today's Groupon: for $70, you get carpet cleaning for two rooms from Clean Image (a $140 value).

Equipped with stain-eradicating contraptions, Clean Image's technicians restore youthful vigor to carpeting by removing layers of contaminants left behind by standard vacuums. The rotary technology of the Rotovac cleaning system buffs interior pastures and frees fibers from oily soils created by cooking vapors, pets, and domesticated motorcycles. As buildups of bacteria and mineral deposits topple, matted threads reclaim their rightful fluff and color. Sudsy authorities break up disruptive allergen parties, improving air quality and forcing underage dust mites to flee. Tapestry beauticians specially treat spots and stains before applying solutions to the entire carpet. If necessary, they place blocks or foil underneath furniture legs to protect them during the drying process and to teach ottomans to walk in heels.
