What is the range of PSI available within Pressure Washer Extension Wands?
Pressure washers use the force of water to clean a surface. Water pressure is measured in pounds per square inch or psi. The PSI rating will help indicate how powerful the water stream will be. GMP or gallons per minute is used to measure cleaning power as well. To get an understanding of the overall power of the washer, multiply PSI by GPM (PSI x GPM). Within Pressure Washer Extension Wands, the highest PSI is 3100 or Greater PSI. At the Home Depot, we consider up to 1899 PSI light duty for vehicles or outdoor furniture. Medium duty, which is recommended for fences or patios, is between 1900 - 2799 PSI. Heavy duty is 2800+ PSI, which is recommended for driveways or to strip paint. We also carry commercial pressure washers, which are considered to be 3100+ PSI. Check out the best-selling product, the 18 ft. Extension Pole with Brush for Pressure Washer.
What's the difference between commercial and residential pressure washers?
The primary difference between commercial and residential pressure washers is the amount of pressure they give. Commercial washers are engineered for high usage and to withstand harsh elements. These pressure washers are typically used daily. Residential pressure washers are usually more budget-friendly but do not last as long as commercial-grade washers.
