Aqua Products ADMXBTT2 DuraMax BiTurbo T2 Automatic Pool Cleaner Demo are designed to handle any size swimming pool. The roving nature of the DuraMAX removes debris from all areas of your pool. Since the DuraMAX is a self-contained filter system, collected debris does not pass into your main pool filter, reducing the need for backwashing. The DuraMAX modular components and heavy-duty drive system provides extended service and dependable performance. In addition, rugged rubber brushes scrub and scour your pool surface for the best results. All DuraMAX vacuums include remote control, air sensor and user selectable cleaning programs which include: user selectable 1 hour delay start, adjustable cleaning cycle lengths (1-7 hours), or continuous run cycles. The DuraMAX Duo unit adds an additional hydro-scrubbing, power washing, jet feature for increased cleaning performance.
