The type of pressure washer needed starts with understanding what the machine will wash. Attributes to consider for your project are pump type and power type. An axial pump is best for small jobs around the house and requires little maintenance. A triplex pump is ideal for frequent use, and maintenance is required. Electric pressure washers are budget-friendly and low maintenance, making them a popular choice for home use. Gas pressure washers are usually more powerful than electric, require more maintenance, and typically last longer.
