If you need to deal with a really tough dirt, clean large areas effectively or work without being limited by a power cord, a gas powered pressure washer would be your best bet. The difference in power and torque when compared to electric units is just huge and they are also a lot sturdier and suitable for a frequent use.
On the other hand, they are also more expensive, heavier, louder and require a little maintenance. Here we present you our most recommended ones with ratings, prices and reviews:
Top power
Most recommended: A quality consumer-grade gas power washer – it starts easily, offers plenty of power and durable construction.
A cheaper but quality unit with only a bit less power – it’s easy to move around and store and starts easily as well.
Top power: Offers the most power of all gas power washers we reviewed and also a knob for regulating pressure – but there are a few design problems as well.
Cheaper
All gas washers don’t have to be expensive units with a tremendous power, here we have a cheaper alternative if you don’t need that much power and prefer to save some cash:
Inexpensive: Designed as an intermediate step between electric and gas machines – it’s easy to use and offers a decent power.
