3.2L Stainless Steel Cat Water Fountain Review

TL;DR: The 3.2L W01S stainless steel cat water fountain is a strong pick if you want a cleaner-feeling, cordless cat drinking fountain with enough capacity for cats or small dogs. The stainless basin, removable design, Type-C charging, included filter cartridge, two spouts, and cleaning brush make it practical. It costs more than the plastic sibling, but the build and cordless setup justify it for many homes.

Verdict: a practical stainless steel cat water fountain for cleaner daily drinking

The 3.2L Stainless Steel Cordless Cat Water Fountain is the model I would choose from this lineup for most cat owners who want a cleaner, more durable-feeling fountain without a cord running across the floor. At $49.99, it sits in the affordable middle of the cat pet water fountain market: more expensive than basic plastic fountains, but still well below many premium smart fountains with apps, sensors, or cameras.

The appeal is straightforward. The W01S combines a 3.2-liter capacity, a stainless steel fountain option, rechargeable power, Type-C charging, automatic circulating water, a removable cleaning-friendly layout, and an included filter cartridge. That combination addresses the biggest reason people shop for a feline water fountain in the first place: many cats ignore a still bowl, but show more interest when water moves. This is not a gadget-heavy fountain. There is no app, no camera, and no smart-home layer. For a water fountain for a cat, that simplicity is a strength if your priority is fresh moving water rather than another device to manage.

It is best for cats that prefer moving water, multi-cat homes that need more than a tiny reservoir, and owners who dislike the smell and film that can build up in lightweight plastic bowls. It also makes sense for small dogs, since the design is suitable for cats and dogs. If you want the absolute cheapest cat bubbler fountain, the sibling plastic model costs less. If you want a sturdier stainless cat water fountain with cordless placement flexibility, this W01S is the better buy.

Who it is for

This stainless steel cat water fountain fits three kinds of homes especially well. First, it is a good match for cats that do not drink enough from still water. The automatic circulating fountain creates visible movement, which can help turn a bowl into something closer to a cats fountain drinker that gets noticed during the day. Second, it works well in apartments and bedrooms because the rechargeable design lets you place it away from a wall outlet. You still need to charge it, but you are not forced to park the fountain wherever a cord happens to reach. Third, it is a sensible choice for people who are tired of sticky water tanks and harder-to-clean plastic corners. Stainless steel does not make maintenance optional, but it is a better surface for routine washing and odor control.

This is not the right pick if your main requirement is a connected feeder-style device with app monitoring or a camera. The W01S intentionally keeps those features out. It is also not the cheapest route to a fountain water cat setup; the $24.99 sibling model is less expensive. But if you are shopping for a cat stainless steel drinking fountain with a more substantial basin and cordless convenience, the W01S lands in a strong value spot.

How we evaluate this cat water fountain

We evaluate pet fountains by looking at verified specs, materials, build, value, and likely real-world use, then update recommendations as owner feedback arrives. We do not claim lab noise tests or long-term filter testing we did not run. For this review, the important details are the W01S model designation, 3.2-liter capacity, stainless steel option, rechargeable power, Type-C cable, automatic circulating flow, included filter cartridge, removable construction, 895 g product weight, and the full accessory set in the box.

For context across categories and prices, we also compare models against our broader best cat drinking fountain picks. That comparison matters because a good kitty water fountain is not just about capacity. It needs to be easy to clean, stable enough not to feel flimsy, simple to refill, and affordable to maintain.

Key features and hands-on design observations

3.2-liter capacity is a useful everyday size

The 3.2L reservoir gives this cat drinking fountain slightly more capacity than the 3L sibling. That difference is not dramatic, but it is welcome if you have more than one cat or a cat and a small dog sharing the same station. A larger reservoir also gives you a little more buffer when you are out for the workday, which directly addresses the worry that pets may not have reliable water if a standard bowl gets tipped, dirtied, or ignored.

Capacity alone does not mean you should leave any fountain untouched for days. Moving water still needs regular washing, and filters need replacement. But 3.2 liters is a practical size for a household fountain: big enough to be useful, not so large that cleaning becomes a chore.

Stainless steel is the main reason to choose this model

The stainless steel option is the defining feature. Compared with a plastic-only cat water fountain, stainless steel has a cleaner, more substantial feel and is less prone to retaining odors when maintained properly. For owners worried about slime, scale, and residue in the tank and water path, this is the version I would favor. It is also the reason this model feels more appropriate as a long-term stainless water fountain for cats rather than a temporary budget fountain.

The product weight reinforces that impression. At 895 g for the fountain itself, the W01S has more physical presence than the 380 g sibling. It is not heavy in a burdensome way, but it should feel less toy-like on the floor. The 1,600 g listing weight also reflects a fuller package with the control module, pump, spouts, cable, brush, filter, and manual.

Cordless rechargeable power makes placement easier

The rechargeable design is a major advantage if your ideal pet water station is not next to an outlet. A cordless cat water fountain can sit near a feeding mat, in a quiet hallway, or in a bedroom corner without a power cord becoming a trip point or chew temptation. The included Type-C charging cable is another practical detail. Type-C is common in modern homes, so topping up the fountain does not require a proprietary cable hunt.

The trade-off is that rechargeable power adds one maintenance habit: you need to remember to charge the unit. If you travel often or strongly prefer set-and-forget plug-in appliances, that is a real consideration. For most households, though, cordless placement is worth the charging routine.

Automatic circulating flow can encourage reluctant drinkers

The W01S uses automatic circulating water flow rather than a passive bowl. That is the heart of any feline drinking fountain. Many cats are drawn to movement, and flowing water can look and smell fresher than still water sitting in a dish. The included two spouts give you setup flexibility, which is useful because cats can be particular about whether they prefer a bubbling surface, a small stream, or a gentler fountain effect.

If your pain point is a cat that refuses a normal bowl, this is the feature that matters most. It turns hydration into something visible and interesting. It is not magic, and some cats still need time to adjust, but a moving water drinking fountain cats can access throughout the day gives you a better shot than another silent bowl in the corner.

Filtration is included, with multi-box filter options

A filter cartridge comes in the box, so the fountain is ready to use without an immediate add-on purchase. The W01S also has 2-box and 5-box filter variants available, which is important for ownership cost. Replacement filters are often where inexpensive fountains become irritating: if refills are hard to find or only sold in tiny packs, maintenance gets skipped. Having multi-box options makes it easier to stock up and keep the cat water fountain stainless setup running properly.

Filtration does not replace washing. It helps the drinking setup, but the basin, pump area, spouts, and water path still need regular cleaning. If you are trying to avoid sticky buildup and hidden grime, follow a consistent routine like the one in our cat water fountain parts cleaning guide.

Removable design and included brush make cleaning less annoying

The removable construction is one of the W01S’s better practical choices. Cat fountains fail as daily-use products when the tank is awkward to access, the pump is difficult to remove, or narrow corners trap residue. This model includes the main unit, main control module, filter cartridge, water pump, Type-C charging cable, two spouts, cleaning brush, and user manual. The included brush matters because spouts and pump-adjacent channels are exactly where mineral scale and biofilm tend to build.

For owners dealing with hard water, the stainless basin is a good starting point, but you will still see mineral deposits if you ignore cleaning. The brush and removable layout reduce the excuse factor. You can take the system apart, clean the contact surfaces, rinse the spouts, and refresh the filter cartridge without treating the fountain like a sealed appliance.

Real cons to consider before buying

The first downside is price. At $49.99, this stainless steel cat water fountain costs about twice as much as the $24.99 3L sibling. The added cost buys the stainless steel option, cordless rechargeable design, higher product weight, and a slightly larger reservoir, but budget shoppers may still prefer the cheaper fountain.

The second downside is that rechargeable convenience requires charging discipline. A plug-in fountain can run as long as the outlet has power. A cordless model gives you placement freedom, but it also adds battery management to your routine. If you are away frequently, make charging part of your refill-and-wash rhythm.

Third, there is no app and no camera. I consider that a benefit for simplicity, but it is still a limitation if you want remote monitoring. You cannot check water activity from your phone or use the fountain as a pet camera. This is a straightforward cat water fountain stainless design, not a connected pet hub.

Fourth, stainless steel is not maintenance-free. It resists odor better than many plastics, but water scale, pet hair, saliva, and filter debris can still accumulate. The removable design and brush help, but owners who want a fountain that can be ignored for long stretches will be disappointed. Any cat drinking fountain needs cleaning to stay fresh.

Finally, the 3.2L capacity is generous for cats, but not a substitute for multiple water stations in a large home or for larger dogs that drink heavily. Since the W01S is suitable for cats and dogs, it can serve mixed-pet households, but I would still use additional bowls or fountains if several animals share the same space.

How it compares with the 3L Automatic Filtered Cat & Dog Water Fountain

The closest alternative is the 3L Automatic Filtered Cat & Dog Water Fountain, which costs $24.99 and has a 3L capacity. That sibling is the value pick. It is detachable, supports filtered drinking, works for dogs and cats, and comes in multiple home-friendly styles. It also offers standard and upgraded versions, including an upgraded option with dry-burn protection and light. At 380 g, it is much lighter than the W01S.

The W01S is the better choice if you want a stainless steel cat drinking fountain, cordless placement, Type-C charging, two included spouts, and a more substantial 895 g body. It also has a slightly larger 3.2L reservoir. The sibling is better if price and color/style options matter most, or if you want a simpler plastic fountain for a secondary location.

My recommendation is clear: buy the W01S if this will be your main feline water fountain and you care about cleaner materials, cordless placement, and easier long-term upkeep. Buy the 3L sibling if you need a low-cost second fountain, a lightweight cat pet water fountain, or a basic automatic filtered setup for a smaller space.

Value and final recommendation

At $49.99, the W01S is a good value for a stainless steel cat water fountain with rechargeable operation. The included accessory set is strong: main unit, control module, filter cartridge, pump, Type-C cable, two spouts, cleaning brush, and manual. You can set it up without immediately buying extra parts, and the available 2-box and 5-box filter variants make ongoing maintenance more manageable.

The biggest reasons to choose it are the stainless steel drinking surface, 3.2L capacity, cordless design, removable construction, and included cleaning tools. Those specs line up well with real owner frustrations: cats that ignore still water, messy tanks that get slimy, awkward cleaning, and unreliable placement near outlets. It is not the cheapest fountain and it is not a smart device, but it is the more grown-up option in this two-product lineup.

If you are shopping for a cat water fountain, cat bubbler fountain, or stainless steel cat drinking fountain for everyday home use, the W01S is the one I would buy first. It offers the right mix of capacity, material quality, convenience, and maintainability without pushing into premium pricing.
