When equipment goes down, the job stops. Cleaning System Specialists, Also known as PressureWasher.net Service Center, helps contractors, fleets, and service operators get back to work with experienced repair support, practical diagnostics, and clear technical guidance. Most service centers guess. McMillen diagnoses and solves jobsite problems with tools that actually work.

Your Jobsite Tells You What It Needs

We educate. We don't sell in the traditional sense. We need you to understand your jobsite, your equipment, and your options.
We're not successful if you're not. Sustainable relationships are foundational to success.

What We Service

Pressure Wash & Steam Systems

All makes and models, 1HP to 100HP, cold or hot up to 350°F. Electric, gas, diesel, or hydraulic
driven. Servicing every brand taught us what actually breaks.

Hot Water Systems & Heaters

Controls and safety devices are where most heaters fail. We diagnose the

root cause and
engineer it out — systems still running at over 35 years are clear proof.

Vacuums, Drain Jetters & Hydro-Vac

Vacuum systems to 1500 CFM, drain jetters with single or multiple pumps, hydro-excavating
systems to 100HP. Single repairs to full system upgrades.

Controlling Wash Water Profitably Expands Your Services

Overspray in a warehouse. Along the waterfront. Downtown sidewalks or in front of a hospital.
A loading dock while forklifts drive by. Kitchens and commissaries left with low humidity and a dry floor, fast.

All of it is profitable. All of it is environmentally friendly. You're inherently a pollution relocation specialist; we make

the tools sharp.

Filtration, Simplified

Filtration can be a huge list of controls. We've simplified it, and we hold the very best patents.
Don't assume it has to be expensive.
Filtration for re-use means not hauling in more water, not discharging on site, not paying wastewater disposal fees, and not damaging your equipment. We use cleanable elements, never disposables that add chores and cost hundreds every few hours, the way our competition promotes.
We match the system to what your jobsite actually needs. Why waste a dime?

40 Years of Knowing How Things Actually Work

Jerry McMillen founded Cleaning System Specialists in 1986 after noticing something nobody in the industry was fixing: service departments had no real training in pump systems or electrical controls.

​

Machines kept failing for the same reasons, and customers kept paying for the same repairs. So Jerry built a different approach, upgrade-repairs. Instead of swapping a part and waiting for the next breakdown, find what's actually causing the failure and engineer it out. Add the right controls. Add the right safeties. Build it so it lasts.

​

Silver plate backgrund

This place is the real deal, I bought 6 pressure washers for our Fire Stations over 10 years ago and they are still running. Jerry and his staff are wonderful to deal with and have the best available equipment for industrial or home use. Reliable and friendly, great combo. Highly recommended.
