The Best Overall

M Mingle 4000 PSI M22 Power Washer Gun & Extension Wand

Our Expert Score


Our Take

This replacement water pressure gun has three lengths: 8.8, 25 and 40 inches. You can easily connect this tool onto any pressure washer or similar accessory that has a ¼-inch plug. Use this power washer gun to clean wood, painted surfaces, lawn mowers, brick, concrete, screens and hard-to-reach areas like driveway crevices.

Our Power Washer Gun Buying Guide

Pressure washers are great for cleaning siding, driveways, sidewalks, patios and decks. They use electric motors or gas engines that power the device’s pump to force out water at high pressure.

The water flows through a high-pressure hose that is connected to an attachment like a power washer gun (also called a trigger gun). These have nozzles that adjust the pressure for your cleaning needs.

You can find electric- and gas-powered pressure washers. Some come with their own trigger guns that eventually need to be replaced, while others require you to purchase this attachment separately. If you need to buy one, make sure to check if the power washer gun is compatible with your power washer before buying. Not all are universal.

You can buy just a spray gun or a full kit. Commercial power washer guns are more powerful, but they can be more expensive. These may come with accessories like connection adaptors, wands in different lengths, nozzles and thread adaptors. A selection of wands can be very helpful when you need to get into smaller or hard-to-reach spaces.

Pressure washers and spray guns work with varying amounts of water pressure, which is measured in pounds per square inch, or PSI. Their water flows are measured by gallons per minute, or GPM. Depending on what you need to clean, you can choose the appropriate PSI and GPM; check for the maximum amounts a device can handle when you are shopping.

Simplemost Fun Fact

Power washer spray guns are not usually that expensive, but the Suttner ST-3500 is one of the costliest ones on the market. This professional-grade tool is made with German-engineered components, has a maximum 5,000 PSI and a maximum flow of 52.8 GPM. It can also handle water temperatures of up to 300 degrees.

A spray gun this strong is probably best left to professionals!

The Power Washer Gun Tips and Advice

  • Before you purchase a new power washer gun, check the connector on your power washer to make sure that it will fit the end of the power washer hose. If it does not, it may leak or otherwise malfunction.
  • Never attach a power washer gun to the end of a garden hose or faucet. It should only be attached to a power washer hose. These are reinforced with wirework and extra-thick plastic, and they usually come with pressure washers.
  • If you have a hot water pressure washer, the replacement spray gun must specify that it is compatible. This is because these pressure washer guns must have high-temperature seals, otherwise they could melt during use.
  • Always wear safety goggles when working with a pressure washer. If you inadvertently spray yourself by mistake, you could suffer a serious eye injury.
  • Use the right PSI and GPM for the job at hand. For example, experienced professionals suggest using 2000 to 3000 PSI/2.5 GPM for cleaning concrete.
