Rotor Arms
Rotor Arms designed to deliver smooth, balanced rotation and powerful cleaning action for surface cleaners and specialty pressure washing equipment. These components play a key role in producing even, streak-free results by directing high-pressure water through rotating spray paths that cover large areas quickly and consistently.
As an important part of advanced pressure washing setups, rotor arms are engineered for durability, precision, and high-performance operation. Their balanced construction and efficient water flow channels help maintain stable rotation, reduce vibration, and ensure consistent spray patterns—whether you're cleaning concrete, pavers, decks, or other flat surfaces. High-quality rotor arms also improve longevity and reduce wear on nozzles, swivels, and other connected components.
This collection is ideal for pressure washing professionals who want to upgrade their surface cleaners, increase cleaning speed, and achieve more uniform results. With strong materials and dependable engineering, these rotor arms support heavy daily use in both residential and commercial environments.
Use these rotor arms as part of a complete pressure washing setup to enhance cleaning performance, maximize efficiency, and deliver flawless flatwork results. With the right rotor arm installed, your equipment will operate more smoothly, consistently, and professionally on every job.
