Does anyone know anything about these machines? Received a supply catolog from them. The are electric Truckmounts, some can come out as portables also. Does not show how much vacuum lift but has 150 psi and .6 gal a min. Heat 180 deg max. 150 feet of vacuum hose. Says optimum psi for carpet cleaning is 150 PSI and 180 degree heat. Just wanted to see your opinions.
