PETKIT Eversweet Solo 2 Review: Does the App-Controlled Water Fountain Earn Its Price?

The PETKIT Eversweet Solo 2 is a small, quiet, app-connected water fountain for a single cat, and after digging through its own spec sheet, owner reviews, and the manufacturer’s support documentation, our verdict is a qualified yes: it’s a genuinely good $45-to-$60 fountain for one cat in a small apartment, but the “app-controlled” label oversells what you’re getting. The app talks to the fountain over Bluetooth, not WiFi, so the low-water alert that owners love only works when your phone is within about 30 to 50 feet of the unit — not from your office or a hotel room. If you want a fountain you can check on remotely, or you’re feeding more than one cat, this isn’t that product.

At a Glance

Best for: a single cat, an apartment or small home, and an owner who mainly wants a low-water push notification and a genuinely quiet pump.
Skip if: you have two or more cats sharing one fountain, you want to monitor water level while you’re away from home, or you’re drawn in by the words “app control” expecting WiFi and remote video.

What Is the PETKIT Eversweet Solo 2, Exactly?

Strip away the marketing and the PETKIT Eversweet Solo 2 is a 2-liter (68 oz) plastic fountain with a cordless internal pump, a three-layer filter, and a Bluetooth radio that talks to the free PETKIT app on your phone. Per PETKIT’s own product page, it runs three modes — smart, normal, and a quieter night mode — and ships without a wall adapter, so budget for a spare 5V/1A USB charger if you don’t already have one.

PETKIT rates the tank at 8 to 10 days of hydration for one to two cats. Independent reviewer testing from Availpet tells a different story: closer to 3 to 4 days for a single cat, with two cats draining it noticeably faster. We’re reporting both numbers because they don’t agree, and a buyer deciding whether to top it off daily or weekly deserves to know that.

A Week With the Eversweet Solo 2: What Changes Day to Day

Set it up on a Sunday and the first thing you notice is how little there is to do. Rinse the tank, snap in the filter, plug the included USB cable into a nearby outlet, pair the app over Bluetooth, and the pump starts a soft, near-silent churn that most owners say disappears into background noise within a day.

Wednesday morning, a push notification lands: water is running low. That alert is the feature owners in reviews mention most as the reason they’d buy the Solo 2 again — a small thing, but it means refilling on your schedule instead of finding an empty tank when the cat is already pawing at it. The catch: that notification only fires if your phone was near the fountain over Bluetooth recently enough to sync. Check the app from a hotel two states away during a work trip, and it won’t tell you anything new, because there’s no WiFi or cloud connection carrying that data out of your house.

By the weekend, cleaning is the whole routine: a quick rinse of the basin and impeller, a wipe with the included brush, and back together in under five minutes. PETKIT’s own support documentation notes most “pump stopped working” tickets trace back to mineral debris or a stuck impeller rather than a hardware defect — exactly what a weekly rinse is meant to prevent. Skip that step for a month in hard-water areas and you’re a likely candidate for a fountain that goes quiet.

Around week four, the app reminds you to swap the filter. It’s a five-second job, but it’s also where the “budget fountain” framing starts to slip — a filter every month is a real, recurring cost, not a one-time purchase, and it’s worth budgeting for before you fall in love with the $45 sticker price.

What Does the PETKIT Eversweet Solo 2 Cost to Run Each Month?

Sticker price is only part of the story on a filtered fountain, so we ran the numbers: device cost amortized over a two-year lifespan, plus a year of filters, against two other current, well-reviewed fountains pulled from their own manufacturer spec sheets. PETKIT comes out cheapest to run day to day, but it’s also the smallest tank of the three by a wide margin.

Fountain	Price	Capacity	App / WiFi	Filter cost/year	Est. cost per month*
PETKIT Eversweet Solo 2	$44.99–$59.99	2L / 68 oz	Bluetooth only	~$25–$35 (4-week filters)	~$4.35
Catit Flower Fountain	$27.99	3L / 100 oz	None	~$45 (30-day filters, $3.75 each)	~$4.90
PetSafe Drinkwell 360	$81.12	128 oz / 3.8L	None	~$43–$87 (2–4 week filters, $9.99/3-pack)	~$8.80

*Device price divided across 24 months plus one year of filters, divided by 12. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.

The takeaway isn’t that the PETKIT is simply “the cheap one.” It’s the smallest tank of the three and the only one built for a single cat, so the lower monthly cost is partly a function of a smaller reservoir and pump, not a free lunch. The Drinkwell 360’s larger tank and multi-pet design cost roughly double per month to keep filtered — a fair trade if you have multiple cats or a household dog sharing the water.

Standout Features: What’s a Must-Have vs. a Nice-to-Have

Must-haves that hold up: the low-water push alert is the feature that earns the “smart” label, and the sub-25dB pump noise is real and consistently praised — multiple owner reviews mention running it in a bedroom overnight without disruption. The cordless pump design, with no cable sitting in the water basin, is also a genuine plus for cleaning and safety.

Nice-to-haves, not dealmakers: the three working modes (smart, normal, night) are a small convenience rather than a reason to buy on their own, and the transparent visualization window is handy but not a substitute for a sensor-based water-level readout.

Honest Dealbreakers

• Bluetooth, not WiFi. The single biggest gap between the marketing and the reality: you cannot check water level or get alerts once you’re outside Bluetooth range of the fountain, typically 30 to 50 feet.
• Single-cat capacity, at best. Between PETKIT’s own 8–10 day estimate and Availpet’s independently measured 3–4 days for one cat, this tank is not sized for a multi-cat household — plan on daily topping off if you have more than one cat drinking from it.
• No battery backup. A power outage or an unplugged cord means the pump simply stops; there’s no fallback reservoir mode.
• Plastic, not stainless steel. The BPA-free plastic build scratches over time and isn’t the right choice for cats prone to chin acne, who typically do better with stainless steel or ceramic.
• Recurring filter cost. Monthly filter swaps add roughly $25–$35 a year on top of the purchase price — budget for it before comparing sticker prices against unfiltered bowls.

Pros and Cons

How We Researched This Review

We did not physically test this fountain. We built this review from PETKIT’s own current product and support documentation, verified retail listings on Amazon and Walmart for pricing and ratings, and independent long-form owner reviews (including Availpet’s hands-on testing) to compare PETKIT’s stated specs against what real owners report months in. Competitor pricing and specs for the Catit Flower Fountain and PetSafe Drinkwell 360 came directly from Catit’s and PetSafe’s own current product pages. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.

Frequently Asked Questions

Does the PETKIT Eversweet Solo 2 use WiFi?

No. It connects to the PETKIT app over Bluetooth, which means your phone needs to be within roughly 30 to 50 feet of the fountain to sync status or receive a low-water alert. It cannot be monitored remotely from outside the home.

How many cats can drink from one Eversweet Solo 2?

PETKIT markets it for one to two cats with an 8 to 10 day tank life, but independent reviewer testing found closer to 3 to 4 days for a single cat. Treat it as a single-cat fountain and plan to refill more often in a multi-cat home.

How often do you need to replace the filter?

Every four weeks, per PETKIT’s own guidance, which works out to roughly $25 to $35 a year depending on where you buy replacement filters.

What happens if the power goes out?

The pump simply stops. There’s no battery backup on this model, so during an outage your cat is drinking still water from the basin rather than filtered, flowing water until power returns.

The Bottom Line

The PETKIT Eversweet Solo 2 is a well-priced, genuinely quiet fountain that does one job well: nudging a single cat to drink more water, with a helpful low-water alert as long as you’re home to receive it. It earns its price for a one-cat apartment on a budget. It doesn’t earn the “smart, app-controlled” framing some retailers lean on — there’s no WiFi, no remote check-ins, and no room for a second cat without daily refills. Multi-cat households and anyone who wants real away-from-home monitoring should look at a larger, WiFi-connected fountain instead.
