1.2 gal (4.5 L) Cordless Pet Water Fountain with Ceramic Bowl

Instead of circulating the same water, this station keeps the bowl fresh by swapping it. A clean-water tank (4.5 L, 1.2 gal) sits above a separate 2 L (0.53 gal) waste tank. On the schedule you choose, the ceramic bowl tips to empty into the waste tank, returns to its place and refills from the clean tank. Pick a 3, 6 or 9 hour interval and a refill amount of 80, 100 or 120 ml (2.71, 3.38 or 4.06 oz) a cycle, depending on how many cats are drinking.

It runs on a built-in 2200 mAh battery that charges in about 2 hours through a Type-C cable (1.5 m, 4.9 ft), and runs for about 15 days between charges depending on use. The set includes a 100-240V adapter, a handheld remote with a range of about 6.6 ft (2 m) and a cleaning brush. Eight silicone pads under the base help keep it from sliding. The shell is ABS, the bowl is ceramic and the hose is stainless steel.

Assembled, it measures about 9.45 x 11.02 x 9.06 in (24 x 28 x 23 cm) and weighs about 3.05 lb (1,382 g) without water. It is meant for several cats or small to medium dogs. Rinse the tanks and bowl regularly with the brush, and empty the waste tank when needed; plan the refill amount around your pet's actual drinking.
