Compare PETKIT Eversweet 3 Pro vs PETLIBRO Dockstream cat fountains on water quality, smart features, capacity, noise, maintenance, and value. See which fits single-cat homes, multi-pet setups, or low-hassle routines (as of February 1, 2026).
TL;DR
Quick Decision
If you want hygiene-focused water treatment and app-based monitoring → choose PETKIT Eversweet 3 Pro.
If you care about larger water capacity and easier daily upkeep for multiple pets → choose PETLIBRO Dockstream Cat Fountain.
If you need a quiet, reliable fountain for a single cat and can go either way on smart features → either works well.
Key Differentiators
The PETKIT’s premium is justified by its multi-stage filtration with UVC sterilization and Bluetooth connectivity for low-water alerts, making it a proactive hygiene system. The PETLIBRO trades those advanced features for a significantly larger tank and dishwasher-safe parts, favoring convenience and longer intervals between refills for multi-pet homes. Your choice boils down to prioritizing smart, preventative water care or hands-off, high-capacity simplicity.
Who Should NOT Buy Either
If you need a truly portable or battery-operated fountain for placement far from an outlet, you should consider dedicated battery-powered models instead.
Use this review to anchor the discussion around PETKIT’s UVC-enabled wireless pump and filtration approach, showing what the hygiene-focused feature set looks like in real use.
PETKIT Eversweet 3 Pro leans hard into hygiene: it uses a 4-stage filtration system (PETKIT Filter 3.0) and adds a UVC wireless pump that claims to remove 99.96% of bacteria. That «extra layer» matters because it targets microbial load, not just visible debris and taste/odor factors that standard charcoal-style filtration typically addresses. In practice, it’s a more comprehensive water-treatment stack than «filter + circulation» alone.
PETLIBRO Dockstream Cat Fountain also uses a replaceable filter and continuous circulation, and the brand positions it around consistent freshness and maintenance cycles (filter replacement every 2–4 weeks). However, in the provided specs/SoT facts, there’s no UVC sterilization claim or multi-stage filtration depth spelled out to the same level as PETKIT’s 4-stage system. So while it can still improve water clarity and reduce odors, it’s not presented as a disinfection-forward design.
Conclusion: On pure water-hygiene capability, PETKIT’s multi-stage filtration + UVC (99.96% bacteria removal claim) is a defensible advantage over Dockstream’s standard filter-and-circulation approach.
PETKIT Eversweet 3 Pro also brings app + Bluetooth into water quality indirectly, because monitoring can reduce the odds of pets drinking stale water: it’s associated with low-water alerts and can stop functioning when water is insufficient (per SoT behavior notes). That fail-safe can prevent the pump from running dry, which can help keep water conditions more stable and avoid degraded flow that discourages drinking. It’s not a substitute for cleaning, but it can support more consistent «fresh water» outcomes between cleanings.
PETLIBRO Dockstream Cat Fountain, as listed in the specs table, shows no app support, meaning there’s less instrumentation to prompt timely refills based on notifications. (Note: one SoT entry describes Dockstream as «app-powered,» but the provided specs context for this comparison states App Support: Not supported, so we can’t credit Dockstream with smart monitoring here.) Its water-quality «control» is therefore more manual—owners maintain quality primarily by topping up and following the 2–4 week filter cadence.
Conclusion: For owners who value hygiene plus monitoring, PETKIT’s connected alerts and low-water behavior give it an additional edge in keeping water fresh and appropriately circulating.
A clean, premium-looking fountain—PETKIT’s «hygiene stack» is the real story here.
Winner: PETKIT Eversweet 3 Pro — It’s the only one here with a stated 4-stage filtration system plus UVC sterilization (99.96% bacteria removal claim), and its app/Bluetooth alerts can also support more consistently fresh water between cleanings.
Smart features
PETKIT’s official setup guide shows the Bluetooth/app pairing flow that unlocks monitoring and configuration—exactly where Eversweet 3 Pro differentiates.
PETKIT Eversweet 3 Pro is explicitly built as a connected fountain: it supports the PETKIT App with Bluetooth connectivity. In practice, that connected layer is meant to support monitoring and adjustments without physically interacting with the unit each time (a meaningful convenience upgrade for owners who want status visibility).
PETLIBRO Dockstream Cat Fountain, by contrast, lists no app support and no wireless connectivity in the provided specs, so its behavior is essentially «set once and run.» Even though PETLIBRO sells app-powered Dockstream variants, the model/spec set here is positioned as non-connected, meaning you won’t get in-app monitoring or remote configuration.
Conclusion: For smart monitoring and configuration, PETKIT Eversweet 3 Pro clearly wins because it’s the only one with app + Bluetooth in the provided data.
PETKIT Eversweet 3 Pro is also associated with safety/automation behavior: it can provide low-water alerts and stop functioning when the water level is insufficient (reported behavior). That’s a practical «smart» safeguard, since it can help prevent the pump running dry and gives owners a clearer maintenance signal beyond noticing reduced flow.
PETLIBRO Dockstream Cat Fountain still relies on manual checks: PETLIBRO emphasizes keeping water between MIN and MAX markers, but there’s no comparable alerting behavior or automatic stop described in the specs provided. So while it can be easy to operate, it’s less proactive about notifying you when attention is needed.
Conclusion: If you value automation around «empty tank» scenarios, PETKIT has the edge due to the reported alerts/auto-stop behavior, while Dockstream is more manual.
Winner: PETKIT Eversweet 3 Pro
Capacity & multi-pet fit
A real-world look at the Dockstream in the one job that matters: keeping cats drinking.
PETKIT Eversweet 3 Pro comes with a 1.8L water tank, which is adequate for single-cat households but typically means more frequent refills if you’re away for longer stretches. Its strengths skew toward «smart» monitoring rather than raw reservoir size, so capacity isn’t where it tries to win.
PETLIBRO Dockstream Cat Fountain ups the tank to 2.5L, a +0.7L increase over PETKIT (about 39% more capacity). PETLIBRO also positions Dockstream for multi-pet use, claiming hydration tracking «for up to 5 cats» (model/feature-set dependent in its marketing), which aligns with the practical reason you’d want more stored water.
Conclusion: On capacity alone, PETLIBRO Dockstream has the clearer advantage—2.5L vs 1.8L is a meaningful bump for multi-cat homes and for stretching time between refills.
PETKIT Eversweet 3 Pro does add «multi-pet resilience» in a different way: it provides low-water alerts and can stop functioning when the water level is insufficient (behavior reported in community/third-party troubleshooting contexts). That can help prevent running a pump dry, but it doesn’t change how often you’ll need to top up a 1.8L reservoir when multiple cats are drinking.
PETLIBRO Dockstream Cat Fountain, by contrast, leans into being a «set it and forget it longer» option with its 2.5L reservoir, which is the more direct multi-pet fit. The trade-off is that capacity benefits don’t automatically equal better monitoring unless you’re buying a Dockstream variant that actually supports per-cat tracking.

Power & placement
Shows how a battery-capable Dockstream variant is set up and moved around—useful for understanding outlet-free placement in practice.
The PETKIT Eversweet 3 Pro is designed around constant USB power: it runs at 5V and is rated at 2W, with a USB cord listed as its power source. It’s also explicitly positioned as for indoor use, which generally implies «near an outlet» placement and less flexibility if you want to relocate it frequently between rooms. In a power outage or if the cable is unplugged, there’s no battery spec to fall back on in the provided data.
The PETLIBRO Dockstream Cat Fountain is more variable by version, but the Dockstream line includes a model with a 5,000mAh rechargeable battery that can last up to 30 days per charge (according to manufacturer/retailer listings). That battery option can make placement meaningfully easier—e.g., on an island, in a hallway, or anywhere you’d rather not run a cable—while still keeping the fountain operating during short outages. Spec sheets also list 5V/1A input and a 100–240V input range (adapter-dependent), which supports easier travel/relocation between outlets when you do plug in.
Conclusion: For true placement flexibility and outage resilience, Dockstream’s battery-capable variants have a clear practical advantage over PETKIT’s USB-powered, indoor-oriented setup.
Handling and moving a fountain matters—cords (or batteries) decide where it can realistically live.

Cleaning & upkeep
PETKIT’s official cleaning tutorial shows the real disassembly/reassembly flow and the parts you’ll routinely wash.
PETKIT Eversweet 3 Pro is positioned as a hygiene-forward fountain (wireless pump + UVC), but that generally comes with a more hands-on routine. PETKIT guidance centers on cleaning the pump, filters, and fountain at least every two weeks to keep performance stable. It also uses replaceable filters and a smaller 1.8L tank, which can translate to more frequent refills that naturally «force» owners to check cleanliness more often.
PETLIBRO Dockstream Cat Fountain also relies on routine care, but the official cadence is broader: periodic cleaning with filter replacement every 2–4 weeks. PETLIBRO additionally positions Dockstream as dishwasher-safe, which can materially reduce scrubbing time for owners who prefer to toss removable parts in with a load rather than hand-wash. Like PETKIT, it uses replaceable filters, but its larger 2.5L reservoir can reduce how often you’re topping up and rinsing the bowl due to low-water exposure.
Comparative conclusion: On pure upkeep convenience, PETLIBRO Dockstream has the edge—its 2–4 week maintenance window and dishwasher-safe claim make it easier to live with day to day than PETKIT’s «every two weeks» guidance. PETKIT’s maintenance load is more predictable and arguably more hygiene-driven, but it demands more consistent owner attention.
Winner: PETLIBRO Dockstream Cat Fountain
Noise & pump design
Top-down view of the Eversweet’s drinking surface—this is where flow pattern and pump noise show up most.
PETKIT Eversweet 3 Pro is positioned as an «ultra-quiet» fountain and pairs that with a wireless pump that also includes UVC (per product listings and the manual). Its pump design is part of a hygiene stack (UVC built into the pump), which can indirectly support quieter day-to-day use by reducing buildup that can make pumps noisier over time—assuming you keep up with cleaning.
PETLIBRO Dockstream Cat Fountain doesn’t make the same noise-first pitch in the provided specs, focusing more on practical design/ownership features like being dishwasher-safe and (in some variants) battery operation. It still relies on regular upkeep—PETLIBRO recommends cleaning plus filter replacement every 2–4 weeks—but there’s no explicit «ultra-quiet» positioning in the given data.
Conclusion: On paper, PETKIT Eversweet 3 Pro has the clearer advantage for noise-sensitive placement (bedroom/living areas) because it’s explicitly designed and marketed around an ultra-quiet, wireless UVC pump, while Dockstream’s differentiators skew more toward convenience and power options than acoustics.
PETKIT Eversweet 3 Pro uses a mixed-material build that includes SUS304 stainless steel plus ABS/PP/silicon, which typically signals a more premium, scratch- and odor-resistant contact surface than all-plastic designs. Its listed footprint is 195×195×148 mm and it weighs 1.28 kg, so it’s more of a «set it down and leave it» fountain than a highly portable one.
PETLIBRO Dockstream Cat Fountain is listed as ABS for primary materials, a simpler approach that can be perfectly functional but usually feels less premium than stainless in high-contact areas. It’s also much lighter at 756 g (1.66 lb), with dimensions of 9.1×7×6.3 in, which can make it easier to pick up, move between rooms, or carry to a sink for cleaning.
Conclusion: On build quality cues, PETKIT has the edge thanks to its SUS304 stainless componentry versus Dockstream’s ABS-only listing; on portability and «easy to move» handling, PETLIBRO wins with 756 g vs 1.28 kg.
Everything laid out: you can see the extra parts that come with PETKIT’s more complex build.
PETKIT Eversweet 3 Pro is also explicitly described as a Bluetooth stainless water fountain designed for indoor use only, which aligns with a heavier, more «appliance-like» presence on the floor or countertop. If you want a sturdier unit that’s less likely to shift when bumped, the 1.28 kg weight can be a practical plus.
PETLIBRO Dockstream Cat Fountain, in contrast, tends to favor day-to-day convenience in handling: the lower mass and smaller overall footprint make it less intimidating to relocate, especially in tight spaces. That said, the ABS-only materials spec provides fewer signals of premium durability than PETKIT’s mixed-material (including stainless) approach.
Winner: Tie — PETKIT Eversweet 3 Pro has the more premium materials story (SUS304 stainless in the mix), while PETLIBRO Dockstream is clearly easier to move and manage physically (756 g vs 1.28 kg).
The Bottom Line
After breaking down hygiene, smart features, capacity, power, upkeep, noise, and build, the choice comes down to whether you value premium water management or everyday convenience and value.
You want cleaner water and smarter monitoring: The PETKIT Eversweet 3 Pro is the better pick thanks to its 4-stage filtration, UVC-equipped wireless pump, and app/Bluetooth monitoring with low-water behavior.
