The PETKIT EverSweet Max 2 is the better purchase for almost everyone shopping today. It keeps the original Max’s 3-liter reservoir, cordless placement, motion activation and app-based drinking logs, then fixes the part owners deal with repeatedly: cleaning.
That does not make the original EverSweet Max useless. Owners whose fountain already works reliably have little reason to replace it. New buyers, however, should choose Max 2 unless the older model is available under unusually favorable conditions. Buying yesterday’s maintenance routine on purpose is not the kind of nostalgia most kitchens need.
Overall verdict: Recommended — buy EverSweet Max 2.
Best for: owners who want a large cordless fountain with app monitoring and dishwasher-safe parts.
Not for: anyone expecting the standard Amazon model to include UVC sterilization, identify individual cats or measure exact water intake.

Research Note
This comparison is based on current PETKIT documentation and the Amazon listings for ASINs B0FHQC19RV and B0CXHM344N. We have not conducted an identical long-term household test of both fountains.
The product reviewed here is the standard dishwasher-safe Max 2 sold through Amazon. PETKIT separately sells an EverSweet Max 2 UVC version. They are not the same configuration, despite naming that makes one water fountain sound like a small cinematic universe.
Most Smart Features Are a Tie
Both fountains use a 3-liter reservoir and can operate without remaining connected to a wall outlet. PETKIT claims up to 83 days of battery use for each, while both offer motion activation, intermittent or continuous flow, low-water pump protection and app monitoring.
The app records drinking frequency and visit duration. That can help owners notice changes in routine, especially within a broader PETKIT smart cat ecosystem. It cannot identify which cat visited or confirm exactly how much one animal drank.
Treat the data as a behavioral trend, not a diagnosis. A sudden change may justify closer observation or a veterinary conversation; it does not turn the fountain into a clinician with a stainless-steel tray.
Dishwasher Safety Is the Real Upgrade
The original EverSweet Max is detachable, but PETKIT explicitly states that none of its components are dishwasher-safe. A deep clean therefore depends on manual washing and careful attention to the pump, channels, tray and reservoir.
According to the Max 2 Amazon listing, every component except the battery pack is dishwasher-safe. The fountain still needs to be disassembled, and the pump area still deserves inspection, but the routine becomes easier to repeat consistently.
That matters because fountain hygiene is repetitive, not occasional. Water, saliva, food particles and hair do not become less interested in forming residue because the product has an app. An easier weekly clean may deliver more practical value than another graph Gerald will never read.
Both models use a stainless-steel drinking tray, but hidden plastic surfaces still require attention. Max 2 wins because more of the complete water path can be cleaned with less negotiation.
Do Not Confuse Max 2 With Max 2 UVC
The Amazon Max 2 listing tied to ASIN B0FHQC19RV highlights dishwasher-safe construction, cordless use, multiple flow modes and app monitoring. It does not say that a UVC pump is included. PETKIT markets Max 2 UVC separately with a wireless ultraviolet pump.
The original Max also lacks sterilization in its standard package, although PETKIT says a compatible UVC pump can be purchased separately. UVC is therefore not an advantage in this specific comparison.
Even when included, UVC would not remove the need for cleaning, filter replacement or fresh water. Light technology is not diplomatic immunity for biofilm.
Battery Life Is a Claim, Not a Calendar Promise
Cordless placement remains the main reason to consider either model. You can position the fountain away from wall outlets, reduce exposed-cord temptation and move it to a quieter drinking area.
PETKIT’s “up to 83 days” figure should be treated as a best-case ceiling. Actual endurance depends on the selected mode, activation frequency and battery condition. Continuous flow will use more power than motion-triggered operation. Napoleon holding a hydration conference every twelve minutes may also affect projections.
The 3-liter reservoir reduces refill frequency, but it should not encourage owners to leave water untouched for weeks. Large capacity is convenience, not preservation.
Why We Would Not Buy the Original Max Today
The original Max still offers the same core proposition: large capacity, cordless flexibility, quiet operation, app records and motion-triggered flow. That is precisely why it becomes difficult to recommend beside Max 2.
Its maintenance disadvantage appears every time the fountain needs a thorough clean, yet it offers no meaningful compensating feature. Unless it is already in your home and behaving well, there is little reason to choose more manual work voluntarily.
This is not an “avoid at all costs” verdict. Existing owners should keep using it, clean it carefully and replace filters on schedule. The argument is narrower: as a new purchase, it loses.
Readers comparing the wider category should also see our best smart cat water fountains guide. Some households may prefer a simpler plug-in fountain, individual-cat identification or a filterless design over PETKIT’s app ecosystem.
Who Should Buy Max 2?
Choose Max 2 when you want cordless placement, a large reservoir, app-based drinking logs and dishwasher-safe water-contact parts.
It is especially sensible for owners who know that complicated cleaning routines gradually become “tomorrow’s problem.” Tomorrow already has enough problems. It does not need a fountain pump marinating in yesterday.
Max 2 is still not perfect. It uses replacement filters, cannot identify individual cats and does not include UVC in the Amazon configuration compared here. But it improves the recurring task most likely to determine whether the fountain remains pleasant to own.
Who Should Keep the Original Max?
Keep it when the pump remains quiet, the battery still performs adequately, manual cleaning does not bother you and your cat already uses it consistently.
Replacing a functioning unit merely because the newer one tolerates the dishwasher would be difficult to justify. Max 2 is the better first purchase, not a mandatory upgrade.
We would only consider buying the original model new if the total value were dramatically better and the seller conditions were trustworthy. Even then, the saving would need to compensate for years of manual cleaning rather than one satisfying moment at checkout.
Final Verdict
PETKIT EverSweet Max 2: Recommended — comparison winner.
PETKIT EverSweet Max: Not Recommended for new buyers; keep it if already owned.
Max 2 does not reinvent the fountain. It keeps the capacity, battery claim, app and cordless freedom, then makes routine cleaning substantially easier. That is enough.

FAQ
Is EverSweet Max 2 fully dishwasher-safe?
The Amazon listing states that all parts except the battery pack are dishwasher-safe. Remove the battery module and follow current cleaning instructions before washing components.
Does EverSweet Max 2 include a UVC pump?
Not in the standard Amazon configuration compared here. PETKIT sells a separate Max 2 UVC version, so verify the exact listing and package contents.
Can either fountain measure how much each cat drinks?
They track drinking frequency and duration, but neither identifies individual cats. In multi-cat homes, the logs represent shared fountain activity.
Should Existing Max Owners Upgrade?
Usually not. Upgrade only if easier cleaning would materially improve your routine, the old unit is becoming unreliable or replacement is already necessary.
