The answer in 30 seconds
Dockstream 2 wins placement and tracking. Eversweet 3 Pro wins stainless tank and UVC.
Choose PETLIBRO Dockstream 2 Cordless for a room without a convenient outlet, a 3 L tank or one-cat drinking trends. Its 30-day battery statement is conditional, its stainless surface is the tray rather than the whole tank, and it cannot identify two cats.
Choose PETKIT Eversweet 3 Pro UVC when a 1.6 L usable stainless-steel tank, compact footprint and manufacturer UVC cycle matter more than intake measurement. Its pump has no exposed wet cable, but the base still requires continuous power.
Choose neither as the only water source. Keep a clean ordinary bowl, especially during adoption, charging, outages or travel. A fountain can reveal a routine; it cannot certify hydration or replace veterinary assessment.

Why this does not cannibalise the first four English posts: those answer automatic-litter, selective-feeding, wet-food and camera decisions. This page owns one separate query — two exact smart water fountains — and resolves power, measurement and maintenance rather than translating a French review.
What current comparisons leave unresolved
The word “smart” hides four different products
Several current comparison pages merge model generations, capacity, wireless power and app functions. These are not minor wording errors: each can send a buyer to the wrong machine.
‘Wireless pump’ means no power cable
False for Eversweet 3 Pro. The pump couples magnetically inside the tank, while the base remains plugged in.
Both apps track how much the cat drinks
False for the exact PETKIT model. Dockstream 2 publishes intake trends; Eversweet 3 Pro publishes control and maintenance functions.
Dockstream 2 holds 2.5 L
That figure belongs to neighbouring Dockstream generations. The current Dockstream 2 page specifies a detachable 3 L tank.
A fountain automatically prevents dehydration
No. Preference varies, food contributes substantial water, and a behavioural trend is not a veterinary diagnosis.
Exact models, dated evidence
Dockstream 2 vs Eversweet 3 Pro comparison table
The table pins Dockstream 2 Smart Cordless and PETKIT Eversweet 3 Pro (UVC) P4108. It does not borrow specifications from Dockstream RFID, an older Dockstream, Eversweet Max or Eversweet Ultra.
| Decision point | PETLIBRO Dockstream 2 | PETKIT Eversweet 3 Pro | What it changes |
|---|---|---|---|
| Exact version | Dockstream 2 Smart Cordless · 5,200 mAh | Eversweet 3 Pro (UVC) · P4108 | Do not substitute the older 2.5 L Dockstream or a different Eversweet. |
| Usable capacity | 3 L / 101 oz | 1.6 L / 54 oz usable; 1.8 L maximum | PETKIT itself explains why the box and usable figure differ. |
| Power | Battery; up to 30 days under stated conditions | Plug-in at all times; wireless magnetic pump | A wireless pump removes a wet cable, not the wall plug. |
| App connection | 2.4 and 5 GHz Wi-Fi | Bluetooth; remote interconnection needs another PETKIT main device nearby | Both have an app, but the connection and remote boundary differ. |
| Drinking data | Amount, frequency and duration for one shared stream | Modes, status and reminders; no intake-volume claim for this model | ‘Smart’ does not mean the same measurement. |
| Water treatment | Four-layer replaceable filter | Filter 3.0 plus manufacturer-claimed UVC cycle | UVC is a PETKIT product claim, not a reason to neglect physical cleaning. |
| Stainless steel | Drinking tray; ABS tank | 304 stainless-steel inner tank | Neither product should be described simply as ‘all stainless’ without this distinction. |
| Dishwasher | Current US page says stainless tray is dishwasher-safe | Official FAQ says no part is dishwasher-safe | The base and electronics never go in water; follow the manual shipped with the exact market unit. |
| Filter interval | Official replacement page: every 2 weeks | Official Filter 3.0 page: every 2–4 weeks | Water, hair and pet count can shorten the interval; use the calculator, not a universal annual price. |
| Dimensions | 246 × 200 × 198 mm | 195 × 195 × 148 mm | PETKIT is smaller; Dockstream buys capacity with a larger footprint. |

PETLIBRO Dockstream 2 Cordless
It is the relevant model when placement away from an outlet or single-pet drinking trends are decisive. Verify that Cordless — not Plug-In — is selected, and treat 30 days as a conditional maximum.

Two incompatible definitions of smart
One measures drinking. The other manages the machine.
Wi-Fi hydration trend
PETLIBRO publishes amount, frequency, duration, trend alerts and maintenance reminders. The standard model does not know which cat drank; playing with water or an unusual approach can also distort a domestic sensor reading.
Bluetooth device control
PETKIT publishes flow-mode control, low-water and filter reminders. Remote interconnection needs another eligible PETKIT device within about 8 m. The page does not claim millilitre intake measurement for P4108.
The burden after unboxing
Filter replacement is not cleaning
Both machines recirculate saliva, dust, hair and environmental debris. A fresh cartridge cannot scrub a film from the tray, rotor, outlet or corners.
- Daily
Look, smell and listen
Confirm clean water, normal flow, no slime, no foam, no unusual odour and no new mechanical noise. Top up with fresh water; do not wait for an app alert.
- Weekly
Disassemble the water path
Unplug or separate the battery base, remove the tray, filter holder, outlet and accessible rotor, then hand-clean according to the exact manual. Never immerse an electronic base.
- 2–4 wk
Replace by condition and official interval
PETLIBRO’s current filter page says two weeks. PETKIT publishes two to four weeks. More cats, hard water or visible debris can justify a shorter interval.
- Monthly
Audit the backup
Clean the ordinary bowl, test alerts, inspect the cable or charging routine and make sure another adult can provide water without the app.
The table a feature ranking cannot replace
What disappears when something fails?
A good smart fountain is not the one with the most icons. It is the one whose failure is visible before the cat loses access to clean water.
| Failure | Dockstream 2 | Eversweet 3 Pro | Owner action |
|---|---|---|---|
| Power cut | Cordless unit can continue if charged | Flow stops; about 60 mL remains in the tray according to PETKIT | Keep at least one clean ordinary bowl available. |
| Battery empty | Flow and tracking stop until a long recharge | Not applicable while mains power is present | Schedule charging before the low-battery alert becomes an outage. |
| Internet down | Local water flow depends on selected mode; remote data sync is interrupted | Bluetooth control may remain nearby; remote interconnection is unavailable | Confirm water physically instead of trusting a stale dashboard. |
| Filter or rotor clogged | Flow may weaken or become noisy | Flow may weaken; anti-dry protection is not a cleaning system | Inspect level, tray, filter path and moving parts every day. |
| Two cats share | Consumption is not attributed to the correct individual | No intake measurement to attribute | Use multiple water stations and direct observation; compare an exact identity model only if individual data is essential. |
Water welfare before hardware
The fountain is one station, not the hydration plan
Cornell’s Feline Health Center explains that food moisture contributes substantially to total intake and that fountain preferences vary. Controlled feline research did not find a universal intake advantage for still, circulating or free-falling presentation.
Keep a clean bowl during introduction and observe which height, material, location and flow the cat actually uses.
One large tank is not the same as independent access. Separate stations reduce the risk that one cat controls the route.
Use app history as context for a veterinarian, together with food, urine, weight, medication and behaviour — never as a standalone diagnosis.
Félinscope 72-hour acceptance protocol
Introduce the object before trusting the data
International Cat Care recommends a staged introduction: fountain in place, then water, then the motor. Our audit adds power, app and backup checks before the return window becomes difficult.
- 01
Place it while switched off
Put the fountain in the intended quiet location with no water or motor so the cat can inspect it without a sudden sound.
- 02
Add water and keep the familiar bowl
Fill to the correct line, leave the old bowl available and confirm the cat can approach without being blocked by another animal.
- 03
Start the lowest-stress flow
Turn on the selected mode, use a rubber mat if vibration carries and watch posture rather than forcing contact.
- 04
Run the 72-hour failure audit
Check level, noise, filter seating, app freshness, cable or battery plan and whether each cat still has an independent water source.

Direct answers
Dockstream 2 vs Eversweet 3 Pro FAQ
Is PETLIBRO Dockstream 2 better than PETKIT Eversweet 3 Pro?＋
Dockstream 2 is the better fit for true cordless placement, a 3 L tank and single-pet drinking trends. Eversweet 3 Pro is the better fit for a smaller stainless-steel tank and PETKIT's UVC cycle when a wall outlet is available. Neither is universally better.
Is PETKIT Eversweet 3 Pro cordless?＋
No. Its internal pump is wireless in the sense that no cable sits inside the wet tank, but PETKIT states that the fountain must remain plugged in to pump water.
Does Eversweet 3 Pro track a cat's water intake?＋
The official page for this exact model lists Bluetooth app control, flow modes, low-water and filter reminders. It does not list drinking-volume tracking. Do not transfer features from Eversweet Ultra or another PETKIT model.
Can Dockstream 2 identify two cats?＋
No. PETLIBRO says Dockstream 2 tracks one pet at a time and directs multi-pet monitoring buyers to its RFID model. Shared use makes a trend household-level rather than cat-specific.
How long does the Dockstream 2 battery last?＋
PETLIBRO claims up to 30 days for one pet in sensor-activated mode on a full charge. The same product FAQ describes roughly 30 sessions a day lasting 45 seconds. More activity or continuous flow reduces runtime.
Which fountain is easier to clean?＋
Dockstream 2 has a detachable 3 L tank, rinseable rotor and a stainless tray that the current US page marks dishwasher-safe. PETKIT's stainless inner tank is compact, but its FAQ says no parts are dishwasher-safe. Both still require full disassembly and hand cleaning of water paths.
Which has cheaper filters?＋
There is no permanent answer because pack prices and replacement intervals vary. On 29 August 2026, PETLIBRO listed eight filters for $26.99 and recommended two weeks; PETKIT listed five Filter 3.0 units for $19.99 and recommended two to four weeks. Use the editable calculator with your local prices.
Does UVC remove the need to clean Eversweet 3 Pro?＋
No. PETKIT's 99.96% disinfection statement is a manufacturer claim about its UVC cycle. Hair, biofilm, mineral deposits, the filter and water-contact surfaces still need physical maintenance.
Will a fountain make every cat drink more?＋
No. Cornell says some cats drink more from fountains, but preferences vary. Controlled research has not shown a universal increase from still, circulating or free-falling presentation. Keep familiar bowls during introduction.
Are the shopping links global?＋
No. The PETLIBRO tracked route was verified to the France/Belgium storefront. The PETKIT PartnerBoost route is labelled France. English editorial reach is wider than these commercial destinations, so other readers should use the official source link and verify local stock, plug, tax, warranty and returns.
