If you ever need to take it to the road, here are some important questions to ask and tips to remember, so you get the absolute best out of your mobile cleaning rig.

Water Tanks

A quality water storage tank is important. Hotsy recommends a 200-gallon tank at a minimum with a float valve and wide access port for trailer rig mounting. Before you mount your equipment, consider size, axle strength, and water sources.

Ask yourself – Will water be available at your job site? If not, what type of water tank will you need on your rig? Here are some answers to keep in mind:

  • Use a single axle trailer for 200-300 gallons of water capacity.
  • Use a tandem axle trailer for 300-500 gallons of water capacity.
  • It’s best to balance the water tank over the axles.
  • Water weighs 8.3 lbs. per gallon – this is important when calculating hauling capacity.
  • Machines should be mounted towards front of trailer to give tongue weight when the tank is empty.
  • Belt drive machine is best to pull from a static water source.

Pressure Washers

The best mobile cleaning units utilize a hot washer pressure washer mount. However, one or more of the pressure washing units of your choice should be considered based on the type of job and the type of trailer you’re using. Certain pressure washers are better for mounting than others.

Ask yourself – what type of pressure washer do I need? How will it be mounted?

  • Placement is just as important as your choice of pressure washer.
  • When mounting your machine(s), pay attention to fuel fill locations and engine exhaust direction.


Optional accessories are always available for your mobile cleaning unit, including hose reels, lights, utility racks, and tool boxes. Be sure to mount these extras around your rig for easy access.
