I've been cleaning for 28 years starting with a manual fill manual pump-out using an RX-20 and quickly after 5 years got my first entry level Truck Mount (a good hot squeaker from Steam Action) Then I moved into a Hydramaster 4.2 CDS trading up to a Power Clean Ind. Nissan powered beast. To tell the truth, I love both the world of TM (Truck Mounts) and Portables (if it's the right portable)
I now have three portables and one TM. If not for my portables I would not have earned the business of two hotels in the Phoenix market earning $36,000 on just over one month. A Truck mount is fast to set up and use, easy to maneuver through a job. It's hot and faster drying. You just can't clean banks that lock you in, huge malls and plazas or high rise buildings.
I have a Rotovac Combination that wins all the time on any job I need it. I upgraded to bigger vac motors, ordered a larger holding tank and because of it's versatile modular design it can be broken down and used in different ways depending on the job you're doing. I can feed my carpet cleaning tool 360 or wand water from the customers hot sink supply. The CFX pulls out the water and is then auto dumped automatically when needed, without me thinking about it. A NON STOP CLEANING MACHINE!
I can also bring in the second module (which comes in two versions a 250 psi and a 1200 PSI pump) which provides me a holding tank that is auto-filled also from the customers hot water supply. I don't have to "bucket brigade" water in and out of the machine. It is topped off constantly with hot water from the customer's hot water heater.
I get the strong drying power from two top performing vac motors and non stop cleaning almost as powerful as a TM.
I use the Rotovac Ranger to clean tile and grout because of the higher psi delivery and when I polish marble or travertine I extract the calcium slurry off the floor and pump out using the CFX side.
