From The Manufacturer

The all-new Hydroshot from WORX is the first-of-its-kind, truly portable, self-pressurized power cleaning and watering device. Its compact and efficient engineering makes it ideal for quick and easy cleaning tasks and eliminates the need for bulky hoses and clunky pressure washers that can damage your items and surfaces. The dual-system design allows for remote watering capabilities and converts to a strong but gentle power cleaner delivering up to 5X more power (320psi) than conventional garden hoses. Use the pressure enhancing lance to achieve that maximum 320psi pressure when you need it most. The lightweight compact design can travel anywhere and draw fresh water from a water spigot or any other source, like a bucket, a pool or even a lake. Two-speed operation allows for additional power when your project demands it or increased runtime depending on your preference. The Hydroshot is a member of the WORX 20V Power Share platform so the battery is compatible with the entire line of WORX 20V DIY yard and power tools.

No other pressure washer is lighter or more portable than the Hydroshot, which weighs 3.7 pounds.

I’m pretty impressed with what the Worx HydroShot 20V Max Portable Power Cleaner is able to do around the house.
- Pro Tool Reviews
First off, it's battery powered, which made it most portable. For small jobs, you don't even need a hose connection, it can draw water from a bucket.

What experts didn't like

Battery life isn't optimal. Only suitable for smaller tasks.
- BestReviews
While we found the WORX Hydroshot WG629 quite capable when washing a car, it struggled to remove the set-in oil stain from our driveway, so it's not very good for heavy-duty cleaning.
- Top Ten Reviews
Just keep in mind that it’s a good tool for cleaning and maintenance tasks but you’ll still need a pressure washer for the really tough jobs.
- Pro Tool Reviews
If you get WG640 or 629, just understand that, in terms of power, it's just a step up from a hose.

An Overview On Electric Pressure Washers

If you’re dealing with caked-on dirt, years of grime or even tough stains, an electric pressure washer is likely your best bet for deep cleaning the outside of your home. Whether you need to power wash your backyard fence or make the sidewalk look like new again, an electric pressure washer can likely help you get the job done quickly and easily.

A pressure washer produces a high-powered stream of water to help you strip away dirt and other substances from a surface. The pressure washer’s stream is much more powerful than that of your average garden hose and is usually more efficient than trying to scrub away dirt by hand. Plus, who wants to spend their precious free time huffing and puffing while cleaning?

An electric pressure washer plugs into a power outlet like any other electric appliance. Generally speaking, electric pressure washers are quieter, smaller and lighter than gas pressure washers. They’re typically best for small projects and they require less forethought than gas models — all you have to do is plug the pressure washer in, rather than running to the gas station to fill up on gas.

You can purchase electric pressure washers with varying levels of power, depending on the types of jobs you think you’ll be doing most often. They range from being able to tackle heavy-duty, commercial-grade jobs to helping you clean the summer’s dirt and dust off your patio furniture. The Sun Joe SPX3000, for example, can tackle light, medium and heavy-duty cleaning projects.

The Electric Pressure Washer Buying Guide

  • One of the most important metrics to consider before purchasing an electric pressure washer is “PSI,” which stands for pounds per square inch. This metric is essentially a measure of how much power your electric pressure washer produces.
  • The PSI generally ranges from 1300 to 3000, depending on the power you need to tackle the task at hand. Some pressure washers are better for small jobs around the house, while others are designed for more difficult jobs in a commercial setting.
  • A light-duty PSI of up to 1900 is good for washing outdoor patio furniture, vehicles and other light jobs. A medium-duty PSI ranges from 2000 to 2800 and is generally good for patios, fences and decks. The Sun Joe SPX3000 generates a PSI of 2030. A heavy-duty PSI is typically in the neighborhood of 2800 and beyond and is good for prepping surfaces for paint and removing tough stains.
  • In addition to its power, you’ll also want to consider the volume of water produced by an electric pressure washer. While the power tells you how much force the electric pressure washer will use when stripping away dirt, the volume of water tells you about the device’s ability to wash that dirt away. The volume of water is labeled in gallons per minute, or “GPM.” Some models are able to deliver 0.53 gallons per minute, while the Sun Joe SPX3000 delivers 1.76 gallons per minute.
  • Do you need accessories with your pressure washer? Some power washers come with useful add-ons, like two different washing wands, a 20-foot hose, a 14-ounce detergent bottle and two “quick change wands” with variable nozzles. Other models also come with an onboard detergent tank in case you want to use soap, as well as a 25-foot hose and three nozzles.
  • To ensure that your electric pressure washer has a long life, you’ll want to perform regular maintenance and cleaning procedures as outlined in the user manual.
  • If you’ve never used an electric pressure washer before, you may consider testing it on a hidden surface until you get the hang of using it.
  • Another factor you may want to consider before purchasing an electric pressure washer is how environmentally friendly it is. Look for a model that uses 80 percent less water and 40 percent more power than the average garden hose.
