We’ll also provide some tips on how to choose the best model for your needs.


First, you’ll need to decide on the purpose of the power washer. Are you going to use it for residential or commercial purposes? If you’re using it for commercial purposes, then you’ll need a more powerful model with higher PSI and GPM. However, if you’re only using it for light-duty jobs around the house, then a less powerful model will suffice.


Those are the two most important factors to consider when choosing a power washer. PSI stands for ‘pounds per square inch’ and is a measure of the water pressure. The higher the PSI, the more powerful the cleaning. GPM stands for ‘gallons per minute’ and is a measure of the water flow. The higher the GPM, the faster the cleaning.

To figure out the cleaning power of a power washer, you’ll need to know the PSI and GPM. You can then use this formula to calculate the cleaning power:

Cleaning Power = PSI x GPM

For example, if a power washer has a PSI of 2,000 and a GPM of 4, then the cleaning power would be 8,000.

Engine Size

Another factor to consider is the engine size. The larger the engine, the more powerful the washer. However, a larger engine will also use more fuel and make more noise. So, if you don’t need a lot of power, then you can save some money and go with a smaller engine. Best engine makers are Honda, Subaru, and Briggs & Stratton.

Types of Connectors

There are two types of connectors that you need to be aware of: quick-connect and threaded. Quick-connect connectors are the most common and are found on most residential power washers. Threaded connectors are less common but are often found on commercial power washers.

Best Brands to Buy

There are a lot of different power washer brands on the market. But not all of them are created equal. Some brands are better than others in terms of quality, performance, and customer service.

Now that you know the different factors to consider when choosing a power washer, it’s time to start shopping around. Compare models and prices to find the best deal. Be sure to read reviews to get an idea of how well the unit performs in real-world use. With a little bit of research, you should be able to find the perfect power washer for your needs.
