Just as the title says I want to expand into pressure or power washing for our TMF academy. Any recommendations appreciated. After doing my research I find I need to answer these questions; 1) Hot water or cold water? 2) Electric start"? 3) How many feet hose? 4) How much psi? 5) Stationary for trailer/truck mounted or portable? 6) Belt or coupler? 7) Reclaim? 8) Surface cleaner brand & size? 9) Filtration? 10) Top brands?
