Gas vs Electric
Pressure washers that are run by a gas motor are generally more powerful than those run by an electric engine. This is because gas motors can hold a larger amount of fuel, which can generate more high-pressure water in a minute.
Where electric engines can spray 1-2 gallons per minute, gas motors can produce between 2-4 gallons per minute. This allows for faster cleaning on tougher stains and dirt, though it has the potential to be damaging to delicate surfaces.
Electric engines are generally smaller, lighter, cheaper, and quieter than gas motors. This is what makes them appealing for lighter jobs, however, they aren’t so suitable for heavy-duty jobs.
The main downside to gas motor-run pressure washers is that they tend to be larger and louder. This is purely down to the power of the machines. They are also recommended for professional and experienced users, as they can damage easily if they are mishandled.
As gas pressure washers are generally bulkier and heavier than electric pressure washers, it’s important to consider how portable they are. Fortunately, gas pressure washers have thick and tall wheels and a handle to pull the washer around.
It’s important to consider the distance of ground you intend to clean, as the length of the high-pressure hose can be the make or break.
Gas pressure washer hoses tend to be anywhere between 20-50ft long, which can be hugely beneficial for cleaning a large area as you won’t have to pull the washer everywhere you go.
You’ve probably seen “PSI” and “GPM” in your search for a gas pressure washer, so here is what they mean.
PSI stands for “pounds per square inch”, and indicates the energy used to push the water to the surface. The higher the figure, which is usually around 3200 for a gas pressure washer, the more powerful the washer is.
GPM stands for gallons of water per minute. The more gallons, the faster the water can clean a surface. Anything between 1-2 GPM is ideal for light cleaning jobs such as yard furniture and semi-dirty patios.
There are 3-4 GPM washers available, which are more suitable for tougher stains and heavy-duty work.
What a Gas Pressure Washer Can Clean
As gas pressure cleaners are more powerful than electric pressure cleaners, they are better suited for heavy-duty cleaning. This includes:
- Removing paint
- Cleaning roofs
- Cleaning gardening equipment such as lawnmowers
- Cleaning gazebos, patios, and decks
- Cleaning garage doors and sliding
- Cleaning dirty grills
Investing in a gas pressure washer can be more cost-effective than hiring professional cleaners, as you can use it whenever you like. They don’t even need to be used too often depending on how dirty the surface is.
Gas pressure washers are not suitable for cleaning painted surfaces or indoor areas such as a basement. They should also be used with a lower pressure on colored bricks and stones, as high pressure can tear away this color.
Frequently Asked Questions
How much does a gas pressure washer cost?
Gas pressure washers are generally more expensive than electric pressure washers. These units can cost anywhere between $250-$800 depending on the power and size.
What is a good PSI for a gas pressure washer?
It depends on the GPM (gallons per minute) as well, but the most common PSI (pounds per square inch) for gas pressure washers is 3200. This is suitable enough to clean a variety of tough stains and surfaces without causing damage.
Obviously, the higher the PSI figure, the more powerful the pressure washer will be. Gas pressure washers can range from 2700 PSI – 4000 PSI. It’s important to understand your intentions for a pressure washer, as you probably won’t need a high PSI for lighter jobs such as cleaning lawn furniture.
Is gas or electric pressure washer better?
This all depends on your intentions! There are advantages and disadvantages to both, but generally speaking, electric pressure washers are the most popular. This is because they are cheaper, lighter, smaller, quieter, and best suited for smaller domestic jobs such as cleaning lawn furniture, decks, and patios.
Gas pressure washers are more powerful than electric ones, which makes them best suited for professional and heavy-duty work such as cleaning driveways, roofs, cars, and garden equipment.
These tend to be larger and louder due to the more powerful motor, and they can produce a larger GPM rate. Gas pressure washers, due to their size, are less easy to store than electric ones. They are also usually more expensive.
Can I use regular gas in my gas pressure washer?
The gas these pressure washers require should be unleaded and clean gasoline. The minimum octane should be 87. Anything with up to 10% ethanol is suitable.
However, do not use E85 gasoline or other unapproved types of gasoline.
It mostly depends on the type of gas pressure washer you have, as each will have different requirements. Some require a mix, others require regular gas.
Due to the nature of gas pressure washers, using the wrong gas can, unfortunately, cause irreparable damage. It is therefore recommended to follow the instructions carefully or to consult with a professional or the manufacturer before using.
Where can I store my gas pressure washer?
Where electric pressure washers can usually be stored anywhere, gas pressure washers provide more of a threat as there is a combustible fuel included. They should not be kept in a home for this reason. The best place to store your pressure washer is in an outdoor shed or garage.
However, it’s also important to consider the colder months where the unit is at risk of freezing. In the case of this, it might be worth considering a heating system in the shed or garage.
