Automatic Scrubbing in Water as Shallow as 8 Inches
Operates Down to 8" Depth
Standard pool robots shut off in less than 18–24 inches of water. Low-profile W20 hydraulics clean right across 8-inch wading shelves.
Wading Pools & Fountains
Purpose-built for resort kiddie pools, architectural reflection pools, fountains, and zero-depth beach entries up to 50 ft.
Dual-Drive Zero-Radius Agility
Split tracks and dual active brushes navigate tight decorative basins, islands, and steps without beaching.
Wireless Remote Included
Steer the W20 manually to high-traffic corners or choose between 1-hour fast turnaround and 3-hour deep cycles.
Swivel Cord + Caddy Included
Ships complete with a heavy-duty commercial transport caddy and anti-tangle cable swivel.
Maytronics Commercial Grade
Engineered for daily aquatic-facility duty and backed by Maytronics' commercial warranty.
End Manual Hose Vacuuming in Shallow Kiddie & Reflection Pools
Shallow wading pools and architectural fountains carry the heaviest sunscreen, sand, and organic load per gallon—yet conventional commercial robots require at least 2 feet of water to prime their vertical exhaust pumps. The ultra-low-profile Dolphin W20 uses side-discharge commercial hydraulics to scrub and filter in as little as 8 inches (20 cm) of water.
Complete Facility Kit
Choose a rapid 1-hour turnaround cycle before morning opening or a thorough 3-hour deep clean overnight. Every W20 ships turnkey with its commercial caddy, wireless remote control, fine and ultra-fine filtration, and anti-tangle swivel cable.

Dolphin W20 Commercial FAQ
How shallow can the Dolphin W20 actually clean?
The Dolphin W20 operates in water as shallow as 8 inches (20 cm), making it ideal for commercial wading/kiddie pools, beach entries, and decorative reflection pools.
Does the W20 climb deep vertical walls?
No—the W20 is specialized for shallow floors and slopes. For standard-depth commercial hotel/HOA pools up to 50–68 ft that need wall scrubbing, choose the Dolphin Wave 60 or Dolphin Wave 80.
