POHIR 24-inch Pro Max Pressure Washer Surface Cleaner & Undercarriage Water Broom — 7-nozzle, 3‑wand, 4000 PSI

POHIR Undercarriage Pressure Washer Attachment Pro Max 24" is a dual-purpose, heavy-duty surface cleaner and underbody water broom that connects to most pressure washers (up to 4000 PSI) to rapidly clean driveways, decks, and vehicle undersides.

This 24-inch professional-grade attachment combines a wide, seven-nozzle cleaning head with a quick-connect pivot coupler and extension wands so you can switch from sweeping horizontal surfaces to reaching under cars without changing tools. Built for both efficiency and durability, the unit is compatible with standard 1/4" quick-connect fittings and is tuned to perform best with 1500–4000 PSI. The low-profile design, rubber wheels, and overlapping spray pattern remove loose debris and loosen stuck grime while keeping sprays contained for faster, safer cleaning.

How does the POHIR attachment speed up outdoor surface cleaning?

The 24" cleaning path and seven high-pressure nozzles cover large areas in a single pass so you spend far less time than with a narrow lance or single-jet nozzle. The water broom mode flattens spray into a controlled, broad sweep, which is ideal for rinsing sidewalks, patios, and sports courts.

• 24-inch-wide cleaning head for wide coverage
• Seven nozzles with overlapping spray to avoid gaps
• Rubber wheels maintain steady contact and glide smoothly
• Compatible with 1500–4000 PSI pressure washers for efficient removal

Can it reach and clean under vehicles or tight low-clearance areas?

Yes — the POHIR undercarriage mode uses the included 16" straight and 45° curved extension wands to access underbody areas where dirt, road salt, and grime accumulate. The low-profile head and pivot coupler let you position the spray horizontally and push the unit beneath bumpers and side skirts without kneeling.

• Extra-long reach with two 16" straight wands plus one 45° curved wand
• Pivoting 1/4" quick-connect coupler locks securely in place
• Low-profile head and durable wheels for undercarriage travel
• Rated up to 4000 PSI for strong, focused cleaning power

What makes this attachment versatile between a water broom and surface cleaner?

The integrated angle adapter and pivoting quick-connect let you reorient the head quickly — moving from a downward-broom sweep for flat surfaces to a forward-facing underbody rinse. All components use standard 1/4" quick connectors, so assembly and mode changes are fast and tool-free.

• Angle adapter converts between sweeping and underbody orientations
• Simple pull-and-pivot knob for selecting spray direction
• Quick-connect fittings on every part for fast swapping
• Works as a sweeper for decks, driveways, pool areas, and courts

How durable and serviceable is the POHIR Pro Max attachment?

Constructed for regular outdoor use, the unit features impact-resistant components and corrosion-aware materials at critical connections. POHIR supports the product with 7x24 customer service and warranty assistance so you can get parts or help when needed.

• Robust nozzle layout designed for long-term spray exposure
• All parts include 1/4" quick connectors for easy replacement
• Manufacturer support available seven days a week for warranty help
• Compatible with common pressure ranges to avoid premature wear
