Buyer’s Guide

The type of fuel source your power washer uses will determine its pressure, volume, and weight. Keep reading to learn more about these factors.

Fuel Source

Power washers are either powered by electricity or gas.

  • Electric: Electric power washers are plugged into a wall outlet. They tend to be more lightweight and affordable than gas power washers, but they have less pressure, which limits what they can clean.
  • Gas: Gas-powered washers can tackle more heavy-duty jobs than their electric counterparts, but they are heavier and more expensive and require more maintenance.

Pressure

Pounds per square inch (PSI) is a unit that measures pressure. A power washer with a high PSI rating is generally more powerful than a power washer with a low PSI. Take a look at the PSI ratings for different washers and determine if they have enough power for the cleaning jobs you need.

Power Washer Pressure

Type PSI Job
Type PSI Job
Electric 1,000–2,000 Washing decks, driveways, patio furniture, and play sets
Residential gas 2,000–3,200 Washing tougher grime found on fences and house siding
Commercial gas 3,200–4,500 Removing graffiti and stripping paint

Cleaning Units

While PSI is a good indicator of power, cleaning units (CU) take into account the volume of water the machine is using as well as the water’s pressure. A machine that uses a lot of water will clean an area faster than a machine with the same PSI rating that uses less water. Similar to PSI, CU change based on the type of fuel source the washer uses:

Power Washer Cleaning Units

Type CU
Type CU
Electric 2,000–8,000
Residential gas 8,000–16,000
Commercial gas Up to 30,000

Weight

If you plan on using your power washer around your house, look for a model with low weight or a model with wheels or backpack straps for easy mobility. Electric models will be lightweight, while gas models will typically have wheels or straps.

Spray

All power washers will allow you to adjust the strength of their spray. A smaller, more concentrated spray has more pressure, making it best for tough jobs, while a wider spray has a lower pressure, making it best for delicate jobs.


Safety Tips for Using a Power Washer

Power washers are highly useful and efficient power equipment for cleaning jobs on anything from rinsing your car to cleaning your grill, but they do carry some risks if you aren’t careful. Here are some of the top safety tips to keep in mind when operating a power washer.

  • Take time beforehand to make sure the area is clear of hazards such as bikes, toys, lawn equipment and trees
  • Don’t use a power washer in the rain or other hazardous weather as it can become a safety hazard
  • Wear proper safety equipment such as safety goggles, work gloves, closed-toe shoes or boots, and ear protection to reduce the risk of injury
  • Avoid pointing a power washer at yourself or others in any circumstances
  • When using a gasoline-powered power washer, make sure you are not operating it in an enclosed space
  • If using an extension power cord, make sure it is clear of any standing water and keep it as far away from possible from the item being washed
  • Keep children and pets away from the area at all times
  • To avoid damaging the surface, operate a power washer on the widest spray nozzle first and make adjustments later if needed
  • Make sure you’re operating the power washer on an even surface and avoid using one on a ladder or rooftop

Frequently Asked Questions

Are power washers and pressure washers the same?

Both power washers and pressure washers use pressurized water to remove dirt and other grime from hard surfaces. However, power washers have a heating element that heats the water, which helps it remove tougher grime. Since power washing and pressure washing are used interchangeably in most cases and both have the power needed for residential use, we treated them as synonymous in this review.

Can you use a power washer to wash your car?

Yes. However, you don’t want the pressure to be too high or you might strip your car’s paint. For the best results, use an electric power washer with a wider spray.

What is a power washer’s GPM rating?

GPM stands for gallons per minute, and it measures flow rate or volume. When calculating CU, GPM and PSI are used.
