oneisall Wireless Filterless Cat Water Fountain — 3.5L, Dual Tank, Stainless Bowl

Effortless hydration for your cat, with no filters to worry about

Meet the oneisall Wireless Filterless Cat Water Fountain, designed to simplify pet hydration without ongoing filter maintenance. It keeps water fresh and reduces the need for frequent filter replacements or pump cleanings. This model is best suited for homes with 1–2 cats and is not recommended for larger multi‑cat households.

With clean and dirty water kept separate, your pet drinks from a dedicated clean-water reservoir while wastewater sits in a separate tank. The system periodically drains waste water, helping minimize the chance of recycled fluids reaching your furry friend and keeping water tasting fresher between fills.

Smart separation and clean water at a glance

• 3.5L clean water tank paired with a 2L waste tank
• Automatic wastewater management helps avoid recirculation of used water

In daily life, this means less fuss and a smoother routine. The design focuses on reliable hydration without the need to stock extra filters, so you can enjoy more time with your pet rather than tending to maintenance.

Cordless convenience, long-lasting power

The fountain runs on a 2000mAh USB‑C rechargeable battery and can operate for months on a full charge. The 3.5L tank size typically lasts several days between refills, making it practical for busy days, travel, or a balcony setup where access to power might vary.

Personalized hydration with a simple interface

• LED display lets you set 6 daily water‑time blocks
• Choose from 3 water volumes (100/120/150 ml) and enable a child lock

These features support tailor-made hydration rhythms that fit your cat’s routines, while the visual display keeps settings approachable for all family members.

Safe materials and easy cleaning

The water bowl is made from 304 stainless steel and the water tank from food‑grade ABS. Detachable parts simplify cleaning, helping you keep the drinking area hygienic with minimal effort.

Quiet operation and dependable support

Designed for a tranquil home, the fountain operates quietly (around 30 dB). It also comes with a 2‑year warranty and 24/7 support. Note: because the unit uses separate tanks, it isn’t a single‑piece design—carry the main unit with both tanks together when moving.

Real‑life use cases

Perfect for regular home use, a balcony setup, or short trips where you want a steady water supply without frequent maintenance. The combination of long battery life, separation of water streams, and stainless steel durability aims to support daily hydration with less hassle.
