Best Petrol Pressure Washer Models

Looking for the best petrol pressure washer for your home or business? Don't open your wallet until you've checked our list of awesome contenders. Here we've done the heavy lifting for you; by both testing and gathering customer reviews of the best petrol pressure washer models available.

Petrol Pressure Washers are commonly found on construction sites, farms, rural properties and in transport yards.

If you are serious about getting quality results, a petrol pressure washer is a solid choice. Compared to electric models, petrol pressure washers are excellent for heavier duty, outdoor tasks and obviously on unpowered work/farm sites. They tend to be noisier than their electric counterparts, but they also generally pack more grunt, which means they can get the job done faster. And because you don't need to be near a power outlet, you're free to move around from job to job. Just remember that petrol pressure washers emit carbon dioxide, so they are not suited for indoor use.

Okay, so which petrol pressure washer should you go for?:


BEST FOR THE HOME: Gerni Super 145.3 Works

Gerni is a name that Australians have known and relied upon for premium cleaning equipment for over 50 years.

What adaptor/accessory would you recommend to go with a petrol pressure washer for cleaning large concrete areas? Some parts of our property have significant concrete build up.

My Generator Response
Hi Ben, For larger concrete areas, look for a nozzle know as a turbo nozzle / turbohammer / powerspeed nozzle - These nozzles will spin a zero degree spray in a wider circle at 3000 rotations per minute. The spinning water jet hits the surface area from multiple angles, quickly breaking down caked-on dirt and grime. As a result, turbo nozzles can cut cleaning time drastically. Excellent for larger concrete areas and for particularly tough to clean surfaces. Some pressure washer models come with this kind of nozzle, whilst for other models you'll need to add it as an optional accessory. Thanks!
