3 Elements to Consider When Choosing a Pressure Washer

When choosing a pressure washer, it is crucial to consider the following elements before making a decision:

1. Electric or Gas

Pressure washers are available in electric or gas models based on your needs. Electric pressure washers are ideal for small jobs as they offer between 1,000 PSI (pounds per square inch) to 1,500 PSI with a GPM (gallons per minute) of roughly 1.5. These units are often quieter, lighter, smaller, and cheaper than gas models, making them the popular choice for small projects around the home. Electric units also have fewer moving parts, drastically reducing maintenance requirements. A major drawback to electric units is that they need to be plugged in, limiting their mobility. Gas pressure washers typically offer upwards of 2,000 PSI and between 2 to 4 GPM, making them the better choice for medium- to heavy-duty projects. They also do not need to be plugged in, making them easier to transport.

2. Hot or Cold Water

While you may think that every pressure washer can use hot or cold water, this is not the case. Hot pressure washers are designed to withstand high temperatures, allowing them to safely handle hot water without the risk of damaging seals or the pump. Cold water pressure washers are the more common and cost-effective option as they are designed to use water straight from the faucet or hose. Cold water units are great for eliminating mud, dirt, and sand, but hot water units are far better for removing oil, grease, and other difficult substances.

3. Power (PSI and GPM)

The power of a pressure washer is the easiest way to determine the type of projects it is suited for. A pressure washer rated with a higher PSI and GPM cleans better and faster, but often costs more than lower-rated units. To calculate the size of pressure washer you need, multiply the unit’s PSI by its GPM to get a true measure of its effective cleaning units (ECU). This is a useful number for comparing models and will help you make an informed decision.
