Electric pressure washers are perfect for household applications and small projects. For example, you can quickly wash your grill, garage door or car. They can be used both indoors and outdoors. They are also quiet and quite easy to start.

Electric pressure washers need a power source which makes them less convenient than gas models. Many manufacturers claim that extension cord isn’t a good solution thus you need to connect it directly to the power source.

Electric pressure washers are best for furniture, patios and decks, as well as small jobs that don’t require stain removal. They are quite and lightweight and don’t require any maintenance. Moreover, they don’t create emissions and stop quickly.

However, they have low water pressure thus taking more time to clean something. Wand and other parts are often made of plastic rather than metal that can be found in gas models. You can’t clean areas outside the reach of your cord which is normally 30 feet.

Gas pressure washers are used for commercial cleaning and large projects. They are much more powerful and can clean up dirt faster. They also tend to have longer lifespans. Besides, they don’t need a power outlet and you can use them everywhere. They deliver high-pressure water and can clean huge area quickly. You don’t need additional cleaning chemicals to dispatch tough gunk such as tree sap or chewing gum. Besides, they allow you to set a nozzle on a wide angle and clean large parts of land at once

However, they produce exhaust and can only be used outdoors. They also make a lot of noise and require wearing ear protection. They are very heavy and require regular tune-ups. These washers can overheat when used for long periods of time ruining the machine if the safety valve doesn’t work.

You will have to winterize the pumps with special antifreeze during cold months, because gas washers can’t be stored inside your home. Besides, high power also means higher chances of injury, as well as splintering, gouging, and damaging surfaces.

PSI or power per square inch is used to measure the power of the water pressure. You need to know the PSI to figure out whether the model will suit for your project. There are models that can be used for all types of work, from small to heavy duty clean projects. This includes siding, fencing, stairs and driveways. There are also heavy duty washers that can clean up paint. However, you don’t need a lot of power to clean your car or your backyard.

GPM or gallons per minute is used to measure how much water is going through the hose every minute. It can help you figure out how much time you need to spend to clean the area. GPM can tell you how much debris will be washed away, too.   •  Light duty models can be from 1,500 to 1,900 PSI and 1.5 GPM   •  Medium duty models can be from 2,000 to 2,800 PSI and 2.8 GPM   •  Heavy duty models can be from 2,900 to 3,200 and 4.0 GPM   •  Extra heavy duty models can be from 3,300 PSI and up and over 4.0 GPM

A Power Level Consumer-grade pressure washers have 3,100 PSI or lover while commercial models can reach 5,000 PSI. However, more power isn’t always necessary. If you only going to clean your house and yard, getting more power is an overkill, and you can accidentally damage the finishes and things like furniture when use the powerful washer. Always choose a PSI rate that you really need.

Maintenance Requirements Gas pressure washers can clean everything but they require proper maintenance. Electric models are less powerful but can do anything related to household cleaning and they have much lower maintenance requirements.

An Adjustable Spray You have two options to alter water pressure – you can either use an adjustable nozzle or change the tip. Of course, both methods work equally fine, but it is a bit quicker to adjust the nozzle than change it every time.

Easy Maneuvering Many pressure washers have wheels to ensure maneuverability. Some of them also have storage for the power cord, trigger and hose. Besides, wheels are necessary to prevent the washer from tipping.

Pump Protection The modern electric pressure washers can stop the pump when the trigger is released. Gas pressure washers can use a relief valve to circulate water when you’re not using the machine. These features are necessary to prevent overheating, which is the main cause of a damaged pump.

Warranty Coverage Most pressure washers have relatively short lifespans – many models can serve you for up to 5 years. Be sure to get a washer that has at least a one year warranty. Gas washers should also have extended coverage period for critical parts. Accessories should also come with a 90 days warranty.

This is an important question that you should find the answer for. It will help you decide how much power you need and how much money you will have to spend. Professionals often choose expensive models that can produce 5,000 PSI and come for $2,000 or more. Less powerful models (that still can do a variety of jobs) are much cheaper.

For homeowners, 3,100 PSI is more than enough and these washers can cost $100-$300. And less powerful washers that are used for moderate clean ups are even less expensive. If you just need to wash your outdoor furniture and equipment, an electric model for less than $100 is a great option.

Will You Use Multiple Spray Tips?  If you know you will need a washer that can perform both heavy-duty and light tasks, you need a model that has multiple spray tips so you can control the water pressure. However, if you only do routine cleaning, a model with an adjustable spray nozzle is a great choice. And you can get a turbo nozzle later if you need more power.
