BWT Pool Products Ultramax Robotic Pool Cleaner Model: RUCL-UM10U-BL98
Take on the biggest pools with a robot built for scale. The Ultramax delivers high-throughput cleaning for large commercial facilities—scrubbing floors, walls, and waterline with aggressive brushes and powerful vacuum intake, then trapping debris in top-access, high-capacity filtration that hoses clean in seconds. Intelligent pathing optimizes long lanes and deep ends to reduce overlap and finish cycles on time, while a rugged chassis and serviceable wear parts keep the unit in rotation day after day.
Made for crews that need quick turnarounds, Ultramax pairs an ergonomic lift design with a long, commercial-grade swivel cable for uninterrupted roaming. Multiple cleaning modes let staff choose a fast touch-up before opening or a deep clean after heavy bather loads, and interchangeable fine / ultra-fine media (bundle dependent) helps you tune capture from storm debris to polishing passes. Use the included caddy (where bundled) for easier transport and tidy storage between runs.
