Frequently Asked Questions:

Q1. ARE GAS POWERED WASHERS BETTER THAN ELECTRIC ONES?

Of course, the pressure of the gas pressure washer is 2-3 times that of the electric, and the all-metal material is very durable. If you have enough budget, we suggest that you add extra money to buy a gas washer instead of replacing your electric washer frequently.

Yes, the hose is changeble. We can replace with a 16mm (5/8”) or larger garden hose.

Q3: WHY DOESN’T MY PRESSURE WASHER REACH FULL PRESSURE?

There are many possible explanations for why your pressure washer isn’t reaching full pressure. Your packings could be worn down, causing your pump to be less effective and have less of a seal around its openings. Your inlet water valve could be clogged, or the filter could be plugged, and not enough water could be getting into the machine. There could be a kink in the hose. Etc.

Q4: WHAT KINDS OF DETERGENTS CAN I USE IN MY PRESSURE WASHER?
