Although we do not recommend the dry cleaning/low moisture as a stand-alone cleaning process, we mostly offer it for interim maintenance at commercial properties. It is a great option for commercial carpet cleaning, on a maintenance plan, because it is cost-effective and carpeting can be used in a shorter time. Pictured below are three examples of dry carpet cleaning processes. The first picture is of a dry/low moisture cleaning typically used by a major franchise. They use water, just not as much. The problem is, the machine is very heavy and has these rotating heads on the bottom which can easily snag the carpet fibers and leave some nasty swirl marks. The extraction is not that adequate and can leave certain areas with more residue than others. After all, they are using a minimal water, so a good amount of residual is left. The second picture is what some dry carpet cleaning services use. In this particular picture, the operator is cleaning a glued down commercial carpet. This is usually fine as it will not distort the carpet fibers. The last picture is of a counter-rotating brush unit. This is what we utilize for both commercial and residential carpet cleaning. It gently lifts the carpet fibers, like a vacuum beater brush would, making it a safe option. As with the previous two, residual is still left the carpet. It really depends on what type of solution is being used and how it crystallizes when dry. Some are sticky, while others crystalize perfectly and can be vacuumed away easily.
