Our TOP Pick
How Do You Pick the Best Gas Pressure Washer?
Gas Pressure Washers
Gas pressure washers are powered by a motor which needs gasoline to work unlike the best electric pressure washers that only need a plug. They will also require more maintenance than an electric pressure washer as the machine will need to be serviced from time to time and you will have to refuel manually. But they do make up for the extra maintenance by providing more power. If you are considering buying a gas powered washer then you need to be aware of the pros and cons.
- Very Powerful
- Paint stripping capability
- No power cord constraints
- Cost more
What is PSI & CU?
PSI stands for pounds per square inch. This is the unit used to measure how powerful the water pressure is. It stands to reason that the higher the PSI the more powerful the pressure washer. The average gas pressure washer usually has between 2,200 and 4,500 PSI and this number goes higher as you approach the very heavy duty models. This is a good indication of how powerful the pressure washer is, but you also have to take into consideration the CU which is the cleaning units. This is the measurement of the volume of water and the pressure that the washer puts out. This is an indication of how much water is pumped out per minute. On average a basic consumer model will have 2,000 – 8,000 CU rating with higher numbers, you will be heading towards the commercial models which might not be suitable for domestic use.
Gas models are heavier than other types of pressure washers, but you will still need to be able to move them around your property. An average gas pressure washer weighs anything from 55 – 90 pounds. It is therefore essential to purchase a gas pressure washer that has a pair of decent hard wheels so that it is easy to maneuver around your yard. There are lighter models that can be lifted and these would probably be useful for yards with rough terrain that would make wheeling the washer difficult.
There are basically two types of nozzles, the adjustable ones and the replaceable ones. The wider the angle of the spray the lower the pressure of the stream of water.
This type of nozzle is connected to the tip of the pressure wand and you can turn the nozzle around for a varying spray width and intensity. These are the all in one adjustable nozzle type of pressure washers.
On the other hand replaceable nozzles give you a wider choice of spray patterns to work with. Being able to interchange nozzles which are usually color coded and come in a set will give you more options. Always turn of the engine completely and drain excess water before replacing the nozzle.
There will be times when you will want to use a detergent or solvent of some kind to get rid of heavy stains. Choose a pressure washer that has this capability. In some cases it is best to presoak the area you want to clean with a chemical degreaser for instance, before cleaning with your pressure washer.
Never underestimate the power of the pressure washer. Many people have landed in the emergency room from injuries received from pressure washers. The power of the water can actually tear through layers of your skin if you come in direct contact with the spray. Avoid using a red zero-degree nozzle as this can cause damage to your property and also serious injury if you come into contact with the spray.
Always read the Owner’s Manual and follow the safety instructions. It is safer to start with the widest angle spray and minimize as this becomes necessary after testing the surface first. It is important that you dress for the occasion with long pants and non-slip shoes, and as an extra precaution it is advisable that you wear safety goggles.

What People Say About Generac 6022 Pressure Washer
1. This is a great first pressure washer for people who need good quality for medium sized jobs. This has been my first pressure washer experience and I’m very happy with my purchase. It’s easy to roll this thing around and since it’s gasoline, and I don’t have to worry about cords getting in the way. I clean the siding on my house to preserve it and keep it looking nice. Works well for that. I also bought a high pressure soap shooter nozzle accessory that helps to get the house siding even cleaner!

2. For the price I paid, $299.99, this is a pretty good pressure washer. I really like Generac products and they consistently seem to roll out high quality machinery. It’s great for decking, siding, driveways, and car washes. I use it for tons of stuff and this machine has more than paid for itself in terms of the time it has saved me. It always does a stand up job of getting things clean. I’m very impressed. Cleaning the tile floor around my pool has never been easier. I recommend this product to anyone who needs a regular duty machine.
