Overview

The Westinghouse PWSC12 is a 12 inch surface cleaner attachment that connects to an electric pressure washer's wand via a universal 1/4 inch quick-connect fitting, rated to 3000 max PSI and 2.3 GPM. It fits driveways, patios, decks, sidewalks, and garage floors rather than vertical siding.

This is a wand replacement, not a standalone tool, so it only works once attached to a pressure washer you already own, and Westinghouse is specific that it is built for electric units, not gas pressure washers. The dual rotating jets and enclosed brush skirt are what separate it from a bare spray wand: the skirt keeps spray contained so you are not soaked or splashing dirty water onto nearby walls and windows.

  • 12 inch cleaning width
  • 3000 max PSI / 2.3 GPM rating
  • Dual rotating jet design
  • 2 lb attachment weight

Who it's for

Fits owners of electric pressure washers who clean driveways, patios, or garage floors and are tired of the streaking a single spray wand leaves. It does not fit gas pressure washers, per Westinghouse's own compatibility note.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Universal 1/4 inch quick-connect fitting
  • Enclosed brush skirt limits splash-back
  • Only 2 lbs for easy maneuvering
  • Rated to 3000 max PSI, 2.3 GPM
What to check first
  • Not compatible with gas pressure washers
  • No reviews listed to confirm long-term seal durability

Performance notes

Two rotating jets spin inside the enclosed deck to cover the full 12 inch width evenly in one pass, which is what eliminates the overlapping streaks a single spray wand leaves. At 2 lbs, the light weight matters for stairs and vertical use on fences, where a heavier attachment would drag on the arm.
