Hi, I am new to carpet cleaning business, but do have some exp from working for a company. I have started a company and now looking for van and truck mount. I am interested in Nissan NV 1500, 2500 or Ford Transit Cargo. But, my biggest headache is about truck mount, as I know that is most important peace. While working for other company I got used to Prochem machine, and thinking that is probably very professional truck mount. I am looking to do residential and commercial. I contacted local shop which specializes in carpet cleaning. But, I want to get right machine. I don't understand difference which effect carpet cleaning of machines that cost $18,000 like Prochem Legend or machine that cost $30,000 like Prochem Everest? Can someone please help me? Thank you!
