The oneisall 10L (2.6 gal) stainless steel dog water fountain is a large-capacity automatic circulating fountain designed for big dogs and multi-pet homes. Key features include:

Capacity & Material: 10L reservoir holds water for a full week; food-grade stainless steel bowl resists rust, survives dishwasher cycles, and keeps water cool even in heat.
Filtration: 5-stage system with a reusable, washable pre-filter sponge (reduces cartridge replacement cost) plus foam and carbon stages to remove odors and debris.
Design for Large Dogs: 20% deeper and wider drinking tray accommodates curled-tongue breeds (Great Danes, Mastiffs) without neck strain or chin drips.
User Experience: Ultra-quiet pump with smart red/blue LED water-level indicator; continuous fresh-water flow with a visual water window (no lid lifting).
Ease of Care: Reusable sponge filter and dishwasher-safe components simplify maintenance.

This fountain suits large dogs and households with multiple pets who benefit from high-capacity, filtered hydration. Stainless steel construction is a durability plus over plastic alternatives.
