Several factors determine your final cost: Square footage is the primary driver, more carpet means more cleaning solution, more time, and higher cost. Carpet condition matters significantly, heavily soiled carpets with ground-in dirt, stains, or pet damage require pre-treatment and additional passes. Add-on services like pet odor treatment (from $25/room), carpet protection (from $0.25/sq ft), and furniture moving can increase the total.
In Minnesota specifically, seasonal factors play a role. Post-winter cleanings (March through May) often require extra treatment for months of accumulated road salt, sand, and de-icing chemicals tracked in from November through April. These mineral deposits are abrasive and can accelerate carpet wear if not professionally removed.
