WOJET Pressure Washer Surface Cleaner 20" with Castors 4500PSI Commercial PA7606 (20 inch) Pressure Washer Accessories

It is compatible with most electric or gas pressure washers that meet the requirements of 2000–4500 PSI and 2–4 GPM. It works well with machines like the Ryobi 3100 and 4400 PSI models. While the unit itself can withstand up to 10.5 GPM, the included nozzles are rated for 4 GPM.

It features a 20-inch cleaning width, with overall product dimensions measuring 20""L x 20""W x 63""H. The item weighs 26.4 Pounds, making it sturdy yet manageable. The package includes a 63-inch high-pressure hose equipped with a 3/8"" Quick-Connect fitting.

The main body is constructed using high-density plastic (ABS) for durability and impact resistance, combined with stainless steel and brass internal components. It features a 3/8"" male Quick-Connect plug on the handle. Please note that if your hose has a male fitting, you will need a female-to-female adapter to connect them.

No, this 20-inch blue model does NOT have a grease fitting (Zerk). It features a fully sealed, maintenance-free swivel that is pre-greased at the factory. This design is intended to be hassle-free and prevents debris from entering the swivel mechanism. Unlike some other models, it does not require periodic greasing, and the spindle is not rebuildable.

It is equipped with two high-pressure spinning nozzles made of stainless steel. These nozzles are specifically optimized to deliver a streak-free cleaning path at 4 GPM. They are designed to remove tough stains, dirt, and grime efficiently while protecting the underlying surface.

It works effectively on various surfaces including concrete, brick, wood decks, tile, and pool siding. Applicable scenarios cover driveways, sidewalks, patios, sport courts, and large outdoor areas. Its four-wheel design and dual handles make it ideal for cleaning expansive surfaces quickly and comfortably.

The installed nozzles and the included replacements are sized to optimize performance at 4 GPM. If you are using a machine with a flow rate higher than 4 GPM, you will need to purchase and install higher flow nozzles to prevent flow restriction and potential damage to the unit. The nozzle bar is designed to accommodate standard pressure washer nozzles.

It supports cleaning with cold, hot, and soap water up to a maximum temperature of 300°F. It is safe for use with hot water pressure washers. However, steam cleaning is not recommended, as the high temperature and pressure may damage the internal seals and components.

You must use a high-pressure hose; a regular garden hose will not work. The handle features a 3/8"" male Quick-Connect, so you may need a female-to-female adapter if your existing hose also has a male end. Assembly is straightforward and requires no special tools, as the package includes all necessary hardware (Teflon tape, rings, pins).

Unauthorized modification, such as attempting to drill a grease fitting or alter the swivel mechanism, is not recommended as it will void the warranty. It is a manual pressure washer attachment that does not require gasoline; it is powered by connecting it to your existing electric or gas pressure washer.

The dual handle design provides excellent stability and control during operation, preventing strain on your arms and back. Combined with the four large wheels, it allows for smooth gliding over rough terrain, making the cleaning process significantly easier and faster than using a standard wand.
