Professional Pressure Washing Equipment

Professional Pressure Washing Equipment

When it comes to pressure washing, having the right equipment is essential to get the job done quickly and efficiently. As pressure washing professionals, we rely on high-quality pressure washers and accessories designed specifically for commercial use. In this guide, we’ll walk through the types of professional pressure washing equipment available and what to look for when putting together your arsenal.

Defining Pressure Washers

A pressure washer (also called a power washer) is a mechanical device that uses a motor-driven pump to produce a high-pressure jet of water for cleaning purposes. Pressure washers are categorized by their PSI (pounds per square inch) and GPM (gallons per minute).

  • PSI refers to the water pressure generated. Most residential pressure washers are in the range of 1300 to 1800 PSI while professional models can reach 4000+ PSI. The higher the PSI, the more cleaning power.
  • GPM refers to water volume. The higher the GPM, the more surface area you can cover. Professional pressure washers usually have 2 to 4 GPM.

When looking at specifications, you’ll generally see the PSI listed first followed by the GPM. A 3500 PSI, 4 GPM pressure washer, for example, produces very high pressure water flow perfect for industrial cleaning applications.

In addition to PSI and GPM, key differences between residential and commercial pressure washers include:

  • Size of pump and motor: Commercial pump and motor units are much larger and more rugged. This gives them extended duty life.
  • Water supply: Standard residential models only handle cold water intake. Some commercial models work with hot water for increased cleaning power.
  • Portability: Wheel kits, flat-free tires, and compact frames provide better mobility for commercial use.
  • Reliability: Top components like AR pumps, Honda engines, and steel frames make commercial pressure washers the toughest in the industry.

Now let’s take a closer look at types of commercial pressure washing equipment available today.

Types of Professional Pressure Washing Equipment

Commercial pressure washers fall into three main fuel categories: electric, gas, and diesel. Each has its advantages depending on your cleaning applications.

Electric Pressure Washers

Electric pressure washers offer a cost-effective, portable way to tackle residential jobs like home siding, driveways, decks, and smaller commercial tasks.

Benefits of electric pressure washers include:

  • Lower purchase and operating costs
  • Compact size for easy transport
  • No emissions for eco-friendly option
  • Quieter operation than gas models

Electric models do face some limitations including lower PSI capabilities and need to stay near a power source. But advances in electric pressure washer engineering continue to push the cleaning power envelope.

Today’s top electric models like the Devi 5 GPM 4000 PSI Pressure Washer provide impressive cleaning muscle in one complete, trailer-ready package.

  • At least 1.5 GPM
  • Rugged motor with thermal protection
  • Big tires and wheel kit
  • At least 50 ft. high pressure hose

This class of pressure washer can tackle residential driveways, sidewalk cleaning, wood restoration, and industrial work like cleaning cooling towers and commercial kitchens.

Gas Pressure Washers

For professional contractors who power wash daily, gas pressure washers are the perfect fit combining rugged design, cleaning versatility and portability.

Benefits of gas pressure washers include:

  • Robust PSI (up to 4000+)
  • Hot water capabilities
  • Larger water volume with 2+ GPM
  • Towable for worksites
  • Lower cost than diesel

The trade-off is gas engines do require ongoing maintenance like oil changes and air filter cleanings. Recoil starts can also be physically demanding.

Workhorse gas models like the Powerhorse Gas Pressure Washer are engineered to withstand repeated use. Commercial-grade features include:

PSI Range2700 – 4000 PSI
GPM Range2 – 4 GPM
Engine/Motor6.5 – 13 HP gas engine
Power SourceGasoline
MobilityWheel kit standard; towable
Water SupplyHandles cold; some hot

Inspecting key components like the pump, engine, and frame can identify the most durable gas pressure washers.

  • Look for triplex or quadraplex AR pumps
  • Minimum 6.5 HP engines from Honda or Briggs & Stratton
  • Protective metal roll cages around pump/engine
  • Big rubber wheels and tow hitches

Well-designed gas pressure washers can power through oil stains on concrete, strip paint from metal, and degrease heavy equipment.

Diesel Pressure Washers

The heavy-duty cleaning choice, diesel pressure washers offer incredible power and durability to dominate the toughest jobs.

Benefits of diesel pressure washers:

  • Extreme PSI levels – 5000+ PSI
  • High-volume water flow with 5+ GPM
  • Towable for large worksites
  • Can run multiple cleaning tools
  • Multi-fuel capability

Of course, the trade-off for brute strength is higher purchase costs and maintenance requirements. Proper diesel operation involves changing fuel filters, oil changes, injector care, and protecting the pump from freezing.

But for non-stop cleaning challenges, diesel models like the Hotsy 560SS Hot Water Pressure Washer are purpose-built to outlast the competition thanks to features such as:

PSI Range2500 – 5000+ PSI
GPM Range4 – 12+ GPM
Engine/Motor11 – 37+ HP Diesel Engine
Power SourceDiesel Fuel
MobilityTowable; wheel kit optional
Water SupplyHot; some cold

When selecting heavy-duty diesel pressure washers:

  • Seek top tier PSI (4000+) and GPM (5+)
  • Look for commercial-grade diesel engines from Kubota, John Deere or similar
  • Verify double steel frame, protective wrap and lift eyes
  • Tool box for accessories should be standard

From stripping industrial tank coatings to washing 18-wheelers, these diesel powerhouses provide the ultimate in cleaning versatility for the professional.

Pressure Washer Accessories

A commercial pressure washer is just the start. You also need high quality accessories designed to optimize efficiency and expand cleaning capabilities.

Here are key accessories to include with any professional pressure washer purchase:
