Step 5: Connect Hoses and Power

• Connect the inlet hose to a water supply

• Attach the high-pressure hose to the spray gun

• Insert your chosen spray nozzle

• Plug into power, switch it on, and test spray after releasing trigger lock

Method 2: DIY Mobile Cart Installation

For users who want to avoid wall drilling, or need a flexible solution for cleaning multiple areas, a custom-built mobile cart is a smart alternative.

Cart Design Requirements

• Strong enough to hold 25kg+

• Top platform size: minimum 50cm x 45cm

• Lower shelf for tools or water buckets

• Lockable wheels for safety

• Space to manage hose retraction

Step-by-Step: Build Your Mobile Pressure Washer Cart

Step 1: Build the Frame

• Cut your wood or metal tubing to form a rectangular structure (L50 x W45 x H75 cm recommended)

• Secure with metal corner brackets or L-joints

Step 2: Install Wheels

• Fix 4 caster wheels to the base (use bolts with washers for strength)

• Ensure 2 wheels have brakes for stability

Step 3: Mount the Top Platform

• Drill the board to match the pressure washer mounting base

• Insert bolts with washers and secure with locknuts underneath

Step 4: Add Storage Shelf

• Install a second platform approx. 15cm above the base

• Useful for storing accessories like soap bottles, extra nozzles, or hoses

Step 5: Mount and Connect Your Washer

• Slide the unit onto the installed base plate

• Attach hoses and power cord

• Use zip ties or clamps to neatly route cords and avoid tangling

• Optionally, add a hook for your spray gun and hang baskets for accessories

Safety & Usage Tips

• Lock the wheels before spraying

• Release pressure before rewinding the hose

• Add counterweight (toolbox or water) on the lower shelf to enhance stability

• Keep the cart indoors or cover when not in use to protect from weather

After Use & Maintenance Tips

• Turn off water and power after each use

• Press trigger to release pressure before hose retraction

• Clean the inlet filter monthly

• Store in dry, shaded area

FAQ

Can I install this on a drywall surface? No, drywall does not support the weight and tension. Use concrete or brick walls only.

Can I build the cart with wood only? Yes, just ensure proper sealing against water and enough joint support.

Does the mobile cart affect retraction? Not at all—as long as the hose has room to extend/retract, function remains smooth.
