The decision primarily depends on your job. It could be for professional or personal use. Their features will determine if the washer fits your needs. We will cover all of these features in this guide.

In the battle of gas vs. electric pressure washer, let’s see which one wins!

Gas Vs Electric Pressure Washer

Gas vs Electric Pressure Washer – An Overall Comparison

PSI of the Pressure Washer

 The psi of a pressure washer indicates one of the two crucial ratings. It is the first rating to consider because it determines the amount of cleaning power you will have.

  • Gas

There is a night and day difference between this and the electric one. The gas power one makes a hefty cleaning job a breeze.

It is due to the higher pressure they can exert. Higher pressure is a prerequisite when you have to handle tough stains.

Usually, the PSI ratings for gas power washers are around 2000 PSI to 5000 PSI. Any pressure washer above 4000 PSI is for professional use.

Because it sometimes can cause damage rather than do good. It could cost you expensive repairs on your property.

  • Electric

The PSI rating, which stands for pounds/square inch, is lower for this category. These come at a low end to moderate pressure rate.

Typically, they may be around 1000 to 2900 PSI. You will be able to accomplish a substantial amount of household chores with these washers.

Water Flow Rate of the Washer

There is a saying in the cleaning industry that PSI does the cleaning, but GPM makes the cleaning faster. Gpm or the flow rate denotes the volume of water that passes through the nozzle per minute.

  • Gas

Standard gas-powered washers have higher GPM. It is the rinsing power of the washer. Higher PSI is usually paired with a considerable amount of GPM.

Low water flow cannot generate enough cleaning power to match the amount of pressure.

We know these washers are very powerful, and their cleaning results are never disappointing. Thus, to exert a higher water force, gas washers have high GPM. Their standard range is from 2 to 4 GPM.

  • Electric

Electric pressure washers have lower GPM in contrast to the previous one. It is low because not much water pressure is necessary for a residential unit.

Therefore, medium PSI with lower GPM gets most of the household job done. The GPM range varies from 1 to 2.5 GPM.

Application of the Unit

Maintenance Scope of the Unit

  • Electric

Electric pressure washers don’t need much maintenance. Although, they require careful handling.

Since they are not made of many durable materials, they tend to break or introduce cracks on the washer body. So you have to be careful that it doesn’t fall or take damage.

  • Gas
