Our equipment is specifically designed to recover virtually all of the moisture used. We use an industry leading gasoline engine powered truckmount (20 horsepower), that has a large blower flowing over 320 cfm, large recovery hoses, and a state of the art titanium carpet wand that is specifically designed for water recovery. Humidity, air flow, and certain other conditions have an impact overall, but you can expect dry times of 4-6 hours. The moisture is applied at approximately 450 psi, which is ideal for cleaning carpet fibers, but not so vigorous as to penetrate beneath the backing. As such, the padding and subfloor stays dry.
For our carpet cleaning services, we happily move most items. Very heavy pieces (full dressers, bookshelves, etc), delicate furniture, or items that are very large (queen size bed) often are not moved, but able to be cleaned around/under in such a manner that all exposed carpet is cleaned. We will walk through the job with prior to starting to discuss which pieces should be moved, and which pieces should stay put. We also base our pricing on the area that is cleaned, meaning that it can often be more economical to clean around items which are not expected to be moved.
