Well Maintained Machines
After a walk through pre-inspection of areas to be cleaned, I will do a pre-vacuuming of areas prior to the pre-treatment with specialty soil removal products. The vacuums I use are high powered commercial grade and are maintained for a clean vacuum on every service call.
In cases of pet contaminants, I may chose to pre-vac with the truck mounted extractor in order to prevent contaminantion entering my vacuums shown here.
In most homes the vacuum cleaner is overlooked for regular service. A high dollar vacuum does not do an effficient cleaning if not serviced properly.
I always have a fresh stock of brush rolls for my machines, as a worn roller loses the ability to agitate the carpet for a much more thorough cleaning. All my vacuums use hepa filtration bags.
