This is one impressive installation. Our customer that ordered this van does carpet & upholstery cleaning, encapsulation, tile & grout cleaning and massive amounts of hard surface cleaning. We designed it to carry 20 air movers, 4 dehumidifiers, a portable and a cimex machine and still have room for the little extra things we all like to carry. Both the vacuum and solution hose reels are electric wind up. You will notice down the bottom, that we have externally ducted the vacuum lines and high pressure solution line. There is a vortex pre filter to catch the high level of debris you can pick up when doing hard surface areas. It also has a on board water tank that can be used to carry fresh water, or on case sensitive jobs, be used to dump dirty water into, as well as what is in the truckmount waste tank.
