FAQ
What to look for in the best gas pressure washers?
Answer: Just like any other machine, there are certain things that you should consider when selecting a quality gas-pressure washer. Some of these include the engine’s power, maximum PSI and GPM, portability of the unit, fuel tank capacity, number of nozzles, ease of use, level of noise, and ease of storage. All of these features play an important role in choosing a powerful and reliable gas-pressure washer.
Are gas pressure washers more portable than electric pressure washers?
Answer: Of course, no. Most gas pressure washers are heavy because they use fuel and require oil, while electric pressure washers don’t need any of these. As a result, gas pressure washers have more parts, such as a big fuel tank that needs to be filled with gas. Also, most electric units like Karcher 1800 PSI or Sun Joe SPX3001 pressure washers are small in size and very lightweight.
Can I use water from the lake to clean the driveway or sidewalk?
Answer: No, you shouldn’t. This is because water flow obtained from the lake may come with debris that may end up hurting the pump. In addition, water from the lake will shorten the lifespan of the pump since most high-pressure hoses are not designed to draw water from a stationary source like a bucket or basin, or even a drum.
How can I winterize my gas pressure washer?
Answer: Both electric and gas pressure washers require one to follow a particular procedure before storing it for winter or for a long period. But unlike electric pressure washers, gas pressure washers require more care. First and foremost, you will have to empty the fuel tank and put in new oil. Furthermore, you will have to empty the water to avoid expansion and cracking inside during the winter period.
The GX390 powered pumps weigh 138lb. The GX200 powered pumps weight about 80lb.
It’s odd you say the GX200 weight is a “con”, but don’t mention even it on the GX390 units? The GX390 is a beast, but it’s very heavy to load and unload!
