ROTARY20SS Rotary Cleaner 20″ SS | 4000 PSI Surface Tool

Overview

The AR-ROTARY20SS is a professional 20" stainless steel rotary surface cleaner
engineered by Annovi Reverberi for contractors, facility managers, and property owners who need
to clean large flat areas quickly and consistently. Paired with a pressure washer up to
4,000 PSI and 8 GPM, this hard-surface cleaner dramatically reduces
striping and swirl marks compared to a wand alone, while cutting cleaning time on concrete, pavers,
and other durable surfaces.

With a rugged stainless steel housing, non-marking casters, and a
balanced rotary spray arm, the AR-ROTARY20SS is built for daily use in commercial environments such
as shopping centers, parking lots, warehouses, loading docks, and maintenance yards. Its
1/4" quick-connect inlet makes hookup fast and intuitive, turning your existing
pressure washer into a high-productivity flat-surface cleaning system.

Key Features & Construction

Stainless Steel Housing & Components

• 20" stainless steel deck resists corrosion, impact, and chemical exposure,
  making it ideal for professional use with detergents and hot water.
• Heavy-duty construction helps the unit maintain shape and balance over time, even after repeated
  transport, loading, and jobsite abuse.
• Stainless steel rotary arm is welded and factory-balanced to spin smoothly and
  deliver an even cleaning path without chatter.
• Designed for operation up to 180°F, allowing use with hot-water pressure washers
  for improved grease and oil removal.

Professional-Grade Rotary Cleaning Head

• Dual high-pressure nozzles mounted on a rotating spray arm create overlapping passes that scrub
  away dirt, algae, and surface buildup in a single smooth motion.
• The 20" cleaning path covers significantly more area than a typical fan-tip,
  allowing operators to clean large pads and walkways far more quickly.
• A nylon brush skirt helps contain overspray, reduce splashback on operators and
  surrounding walls, and maintain a consistent standoff from the surface.
• Rotary motion minimizes streak marks and “tiger striping” common when flat work is done with a
  hand-held wand alone.

Mobility & Ease of Use

Non-Marking Casters & Tilt Handle

• Equipped with four non-marking casters that roll smoothly across concrete,
  sealed surfaces, and coated floors without scuffing.
• The wheel layout supports the weight of the unit and spray reaction forces, reducing operator
  fatigue on long cleaning runs.
• A tilt handle design makes it easy to maneuver around obstacles, ramp up
  curbs, or reposition the cleaner while maintaining good ergonomic posture.
• Simple push–pull motion is intuitive for new operators while still allowing experienced users
  to move quickly across large areas.

Quick-Connect Inlet & System Compatibility

• Uses a 1/4" quick-connect plug inlet, allowing rapid hookup to most
  commercial spray guns and lances without tools.
• Rated for pressures up to 4,000 PSI and flows from roughly 3 to 8 GPM,
  making it compatible with many mid- to larger-frame pressure washers.
• Accepts water temperatures up to 180°F, so it can be used with hot-water units
  for faster cutting of oils, grease, and heavy contamination.
• Works with both belt-drive and direct-drive pressure washers, provided specifications are within
  the rated PSI, GPM, and temperature limits.

Ideal Applications

Commercial & Industrial Flat-Surface Cleaning

• Sidewalks, plazas, and walkways: Remove compacted dirt, chewing gum, algae,
  and traffic staining around schools, campuses, and retail storefronts.
• Parking lots & garages: Clean traffic lanes, parking bays, and ramps more
  efficiently than with a standard wand, helping restore appearance and traction.
• Warehouses & industrial floors: Maintain concrete shop floors, loading docks,
  and work zones where forklifts, pallet jacks, and equipment leave heavy grime.
• Restaurant & food service exteriors: Tackle grease-spotted dumpster pads,
  drive-through lanes, and back-of-house service areas.

Facility & Property Maintenance

• Municipal and campus maintenance: Ideal for parks, public squares, transit
  platforms, and building plazas where appearance and safety are priorities.
• Residential and HOA work: Speed up cleaning of driveways, pool decks, and
  community walkways while delivering a more uniform finish.
• Contractor services: Perfect add-on tool for pressure-washing businesses
  looking to increase productivity and deliver consistent, professional results.
• Pre-paint and sealing prep: Use to prepare concrete and pavers before
  sealing or coating, ensuring clean and even surfaces.

Usage & Best Practices

Setup, Operation & Care

• Match your pressure washer’s PSI, GPM, and temperature output to the AR-ROTARY20SS ratings to
  avoid damage and ensure optimal cleaning performance.
• Flush the system with clean water before and after detergent use to protect the rotary arm and
  nozzles from chemical buildup.
• Inspect nozzles regularly for wear; oversized or eroded tips reduce pressure and cleaning
  efficiency and should be replaced in pairs.
• Periodically check the casters, brush skirt, and rotary head for debris and wear so the cleaner
  continues to glide smoothly and maintain even cleaning results.
