Hose length: 25 ft
Weight: 63 lbs
Reasons to buy
+Heavy-duty pressure capability +Highly durable design+Half gallon soap dispenser

We’ve picked this pressure washer because the steel frame construction was built to last. Though it's pretty heavy, the never-flat wheels make moving it over any outdoor area convenient and easy to use. 

How to use

Recommended for larger cleaning tasks, as this model can deliver a powerful pressure washing. You'll have to switch between three pressure nozzles and one soap nozzle to utilize different pressures for different tasks.

Power output

The 2700 psi pressure capability combined with the half-gallon soap tank makes it the perfect power washer when dealing with ground-in dirt on brick, stone, concrete, wood, or iron. Just switch to the low nozzle to use the reduced power for more delicate surfaces such as car bodywork and decorative paving.

Added features

The maintenance-free axial cam pump is a nice feature, as is the lightweight EndraGrasp spray gun with a locking feature. With a Quick Start Guide, engine oil, and tools included, you can get to power washing sooner than later.

This pressure washer can handle a wide range of cleaning projects. With a decent price and practical features, it's a good choice for your pressure washing jobs.  

How to use

You’ll be able to blast clean everything from cars to decks in no time with this Sun Joe model. The two .9 liter removable detergent tanks allow users to add different soaps if necessary to cut through the tough grease of a grill or the grime on an RV.

Power output

Whether it’s giving flowerpots a quick scrub or blasting a driveway that has seen better days, this pressure washer can deal with most jobs. Some users get confused when they see the marketing materials highlighting an internal 2030 psi because in reality, the Sun Joe has a 1450 psi working pressure (it doesn't lessen the quality of the model, just means it can't do super heavy-duty washing). Add in the fact that this is an electrical piece of equipment (no need to buy gas!), and the Sun Joe is a good choice for anyone. 

Added features

It’s easy to store after use and the two rear wheels make it easy to maneuver. Another benefit is that Sun Joe offers a two-year warranty from the date of purchase: no questions asked.

Which is the best pressure washer?

We’ve picked the   Kärcher K2 Premium Full Control Car and Home Pressure Washer, as it comes with a selection of handy attachments, is easy to use, super light, and has a good price to boot. Read on for our full review along with details of our other favorite buys this year and how to choose the best model for your cleaning needs.

How to choose the best pressure washer

When it comes to picking the most suitable product for your needs, there is a lot more to consider than price. While we all love a bargain, you often get what you pay for, and by spending a little extra, you can get a washer that will last longer and work wonders. 

Pressure

Pay close attention to the pressure capability to see if the pressure washer will tackle the tasks you need it to with ease. Models with 1300-1800 psi should be fine for cleaning mud off bikes and lawn furniture, light mildew removal, and spot cleaning. For patios, deck, siding, and other heavy-duty jobs, you'll want a better model with 2,000-4000 psi pressure capability. 

Cable size

Check how long the lead is, as well as the length of any hose or attachments in order to make sure it will do the tasks you want it to. Does it need to reach high up to tackle the roof of the car for instance? Is it easier to have something that can reach around the side of the house to clean the front path or driveway without having to unplug and re-start? Know what you need your pressure washer to do, to determine the right length of cable and hose. 

Design

A good design can go a long way. You'll want something that's simple to put together, easy to use, and lasts against wear and tear and all weather conditions.
Don't forget to ask yourself questions like: Does it look or feel cheap or is it more robust? Do the attachments look durable enough? If it comes with a range of add-ons, do you really need them or are you paying for things you won’t use on a regular basis?
