WILKIEE FS30 Stainless Steel Cat Water Fountain, 4 L, Cordless

With a 135 fl oz (4 L) capacity and a stainless steel body, the WILKIEE FS30 is designed to keep drinking water available for indoor cats between refills.

Its built-in 4000 mAh battery supports cordless placement, while a detachable design lets you charge the fountain without moving the whole unit.

Choose between smart sensing, timed flow and continuous flow when plugged in. Which water style will your cat prefer: a tap-like stream or a softer ripple?

What you’ll notice day to day

The smart-sensing mode releases a 15-second stream when a cat approaches within 6–8 feet. For a steady routine, select timed flow, or use continuous flow while the fountain is plugged in. The low-water indicator light makes it easier to spot when it’s time to refill.

Two flow styles add flexibility: faucet flow mimics a running tap, while leaf flow creates a softer, rippling stream. The 6-stage filtration system includes carbon, resin and mineral stones to filter the water as it circulates. A 25 dB operating-noise rating and gentle stream are designed for quieter indoor use, including in a bedroom.

Buyers commonly highlight the quiet flow, straightforward cleaning and ease of use, as well as their pets’ interest in the fountain. These are individual customer impressions, while the documented features include the choice of flow modes and the filtration system.

Key points

The cordless setup makes it easier to place the fountain where your cat already drinks, rather than choosing a spot solely around an outlet. When charging is needed, the detachable design means you can remove the relevant part without carrying the full fountain to the plug. The built-in battery is specified for up to 45 days of use.

A 4 L reservoir offers more water capacity between refills than a compact bowl or smaller fountain, which can be useful in a home with more than one cat. The stainless steel construction gives the unit a practical, wipeable surface for everyday use. Three operating modes let you select between motion-triggered water, timed flow and continuous operation when plugged in.

Best use cases

This indoor fountain suits cat owners looking for a circulating-water setup with flexible placement and a generous reservoir. For example, it can sit in a familiar drinking area away from the main walkway, with smart sensing selected to release water as a cat approaches. In a multi-cat home, the larger capacity can reduce how often you need to top up compared with a smaller-capacity fountain.

If you’re choosing between a fountain that stays beside an outlet and one with battery-powered placement, the FS30 offers the latter, alongside a continuous-flow option when plugged in. Its faucet and leaf styles also let you change the stream without changing the fountain itself.

Should you buy it?

The WILKIEE FS30 is a practical fit for indoor cat households that want a stainless steel fountain with cordless placement, selectable flow modes and a 135 fl oz (4 L) reservoir. Its sensing option, low-water indicator and two stream styles make it easier to tailor daily watering to your space and your cat’s routine.
