It’s compatible with most electric/gas pressure washers meeting 2000–4500 PSI and 2–4 GPM (original max flow rate 4 GPM). It can withstand up to 10.5 GPM when replacing nozzles, fitting common household/commercial models like Simpson. For flow rates over 4.5 GPM, remove the 3D filter to avoid blockages.

It has an 18-inch cleaning width, with overall dimensions 20""L x 20""W x 8""H. The package includes a 1-piece extension wand for added reach. The outer box is slightly larger for safe shipping (exact size subject to delivery).

The main body is crafted from top-notch 304 stainless steel, ensuring anti-rust, corrosion resistance, and durability. It adopts a standard 1/4"" Quick-Connect design for easy assembly with pressure washer wands, plus a pre-greased, fully sealed upgraded swivel to prevent leaks and clogs.

It is equipped with two high-pressure spinning nozzles for streak-free cleaning, supporting power and soft washing modes. The nozzles are optimized for 4 GPM flow rate and 4500 PSI pressure, and the unique 3D filter stays securely in place to prevent nozzle clogging during operation.

It works for various surfaces including concrete, wood decks, tile, brick, asphalt, and siding. Applicable scenarios cover driveways, sidewalks, patios, garages, curbs, and pool surrounds—suitable for both residential and light commercial use, and effectively removes oil stains, grime, algae, and stubborn dirt.

The package includes 2 replacement nozzles and 5 additional spray nozzles for versatile cleaning. All nozzles fit the 1/4"" interface and match 4 GPM/4500 PSI performance. For higher flow rates (up to 10.5 GPM), replace with matching high-flow nozzles; use the included nozzle cleaner for clogs. Replacement nozzles can be obtained by contacting the seller.

Use a high-pressure hose (not a regular garden hose) with 1/4"" Quick-Connect. Remove the 3D filter if your machine’s flow rate exceeds 4.5 GPM. Rinse after use, clean nozzles with the included tool, and rely on the pre-greased swivel for low-maintenance operation.

Unauthorized modification (e.g., altering the swivel or filter) invalidates the warranty and risks damage. It’s a manual pressure washer attachment (no gasoline needed)—powered by connecting to electric/gas pressure washers meeting 2000+ PSI and 2+ GPM.

The package includes 1 surface cleaner, 1 extension wand, 2 replacement nozzles, 5 spray nozzles, 1 spray bottle (for detergents), 1 nozzle cleaner, Teflon tape, and a user manual—everything needed for immediate setup and versatile cleaning.

Assembly is straightforward and takes only a few minutes with clear instructions included. The 1/4"" Quick-Connect design allows tool-free attachment to the wand, making it easy for beginners to set up and use.

It has a super-thick, high-density brush skirt designed to contain over-spray, keep debris in place, and keep you dry during cleaning. Note that the brush is not intended for scrubbing—only for splash protection.

For first use, ensure your pressure washer is set to 2000–4500 PSI and 2–4 GPM. Move the unit slowly across surfaces, avoid rushing, and use the appropriate nozzle (power wash for tough stains, soft wash for delicate surfaces) to achieve streak-free results.
