Another important factor that is directly related to cost is the durability of the pressure washer. Before you spend your hard-earned income on a pressure washer, ensure you consider the number of times you will be using it, whether you will be using it for commercial purposes or you will be using it for domestic purposes only. 

If you are buying the pressure washer for commercial purposes then it means you will be using it very frequently hence you should consider a model with OHV engine for added reliability and performance. Besides, it should have a triplex grade pump for commercial purposes.

Cleaning Systems

Last but not least, you should ensure you check the nozzles of the pressure before buying it. There are different types of nozzles of a pressure washer. Adjustable nozzle sprays are mostly preferred because you can easily change the pattern from wide to pinpoint spray. Besides, you should ensure you buy water pressure with predefined spray patterns to help in precise control.
