Collection: Pressure Washers

Hot water and cold water pressure washers differ in their cleaning capabilities and recommended uses. Hot water pressure washers use high pressure and heat to dissolve stubborn materials like grease, oil, and grime, making them ideal for commercial or industrial environments. Cold water pressure washers are lighter, less expensive, and easier to maintain. They are suitable for home or light commercial cleaning jobs like patios, driveways, and siding. However, they require more chemicals or detergent to remove oily residues. Depending on the cleaning issue, hot water washers are ideal for removing grease and saving time, while cold water washers are more versatile and economical for routine cleaning tasks.

Pressure (PSI) and flow (GPM) are crucial for efficient cleaning in pressure washers. PSI measures the force of water expulsion, essential for removing stubborn stains or grime. GPM indicates the volume of water delivered, allowing for faster rinsing. Higher GPM is more valuable for large or commercial projects, while higher PSI is essential for tough impurities or hard surfaces. Balancing PSI and GPM to meet specific cleaning needs yields the best results.

A pressure washer uses a motor or engine to convert tap water into a powerful jet for cleaning stubborn surfaces. The pump pressurizes the water through a small opening, increasing its velocity and cleaning capacity. The user controls a trigger gun to release the pressurized water through a nozzle, which can be modified by different nozzles for different cleaning jobs. The main parts of a pressure washer include a water inlet, filter, motor, pump, hose, trigger gun, and replaceable nozzles. Some models also have detergent injectors for better cleaning results.

Selecting the right pressure washer nozzle is crucial for efficient cleaning. There are various types of nozzles, including red (0°), yellow (15°), green (25°), white (40°), and black (soap). Red nozzles are ideal for hard surfaces, while yellow nozzles are ideal for heavy-duty tasks. Green nozzles balance pressure and coverage, while white nozzles offer a softer, wider spray for delicate surfaces. Black nozzles are for low-pressure soap or detergent applications. Turbo or rotating nozzles combine high pressure with broader coverage for difficult surfaces. Start with a wider angle nozzle and test on a small area.
