Pressure washer FAQs

The most common questions about pressure washers are answered below. For more specific questions, we usually have relevant answers at the bottom of each of our posts. You can also reach out to us at any time for more personalized advice.

How does a pressure washer work?

Pressure washers aren’t complicated. There’s a power source (either a gas engine or an electric motor) and a high pressure water pump. The pump draws water in, pressurizes it, and releases it (by pulling the trigger on a spray gun, which is connected to the pump using a high pressure hose).

Karcher has a cool visual animation that shows the process in action.

How much does a pressure washer cost?

Pressure washers start around $100, but they can easily cost thousands depending on what features you’re looking for. If you’re a homeowner, expect to pay $100-500. If you’re a business owner, expect to pay $500 and above.

How do you fix a pressure washer?

Unsurprisingly, this depends on the issue and the cause of that issue. For example, if your gas pressure washer won’t start, it could be a bad ignition coil, or you could just be out of gas (whoops). Try to figure out the source of your problem and go from there.
