PETKIT EverSweet Max 2 UVC review

The PETKIT EverSweet Max 2 UVC P4116 combines a three-liter reservoir, a stainless-steel drinking tray, rechargeable operation and an included UVC wireless pump. Its most useful distinction from the earlier Max is the current model's documented heat-resistant removable parts and dishwasher permissions. It suits an owner willing to separate the wet pieces from the electrical control module and check the flow behavior of the supplied firmware.

Battery power is real, but mode conditions matter

The unit can operate on its built-in battery or USB power. The US page says the power adapter is not included and specifies five volts at one amp, so plan the appropriate power supply as part of setup. The battery powers the fountain itself, rather than merely preserving settings during a power interruption.

The manufacturer-linked P4116 manual describes continuous and intermittent choices while plugged in. Its battery section describes a default twenty-five-second dispense each hour, with frequency adjusted through app energy management. That is a different operating arrangement from continuously pumping on battery. The up-to-eighty-three-day promotion is not evidence of eighty-three days of continuous flow, and it says nothing about how long the water can be left unchecked.

The current US product page additionally advertises motion-activated flow, whereas the linked manual does not explain the corresponding power and firmware conditions. The confirmed baseline is wired continuous or intermittent operation and battery interval operation; obtain the exact current instructions before relying on a particular battery-and-sensor combination.

Steel tray, plastic reservoir, separate electronics

The drinking tray is 304 stainless steel. The reservoir and other parts are different materials, so this is not an all-steel water path. The current US specifications clearly label the body dimensions as width, depth and height, with the height given as 7.51 inches. Leave additional room to lift the tank and control module and to handle the lid.

The wireless pump eliminates an exposed cable between that pump and its powered base, but remains an electrical pump in the wet assembly. A lift-off tank containing such a pump is different from a reservoir whose motor and electronics all stay in a dry base. Compare those constructions specifically if that separation is the main reason for replacing an existing fountain.

Dishwasher permission has a component boundary

The current comparison lists the tank, tray, lid, filter holder and outlet pipe as dishwasher-safe parts. Remove the control module and wireless base and keep them out of the wash. The manual expressly prohibits rinsing or soaking those electrical components. The broad advertising phrase about dishwasher-safe construction should not override the more specific removable-parts list.

The linked cleaning guidance recommends at least weekly tank cleaning and a deeper monthly clean, adjusted for the household's water and use. Filters have their own replacement schedule, with the current FAQ suggesting four weeks. Replacing a filter does not clean the tray, water passage or pump, and neither interval is a reason to ignore visible debris earlier.

App records are visits, not a measured intake total

The fountain connects to the PETKIT app by Bluetooth. The documented records cover drinking frequency and duration, alongside battery, filter and water-status information. Those are useful activity records, but they do not establish an individually measured milliliter total for each cat. Multiple profiles do not turn this sensor system into RFID or camera identification.

Direct phone interaction needs Bluetooth proximity. The manual describes remote interconnection through a compatible PETKIT master, not direct Wi-Fi in the fountain. Its interconnection section names PETKIT smart-feeder and self-cleaning litter-box series as supported; it excludes Fresh Element P512 and Fresh Element Mini P530, and requires pairing within 8 meters with current master software. Two current U.S. bundle pages pair this P4116 with YumShare Solo 2 P572 or YumShare Dual-Hopper 2 P592. The guide names the feeder family rather than those codes individually, so treat those exact bundle pairings as a series-level master setup, not a model-code certification. Without a compatible master, plan on local Bluetooth.

Where it belongs on a shortlist

The included UVC pump requires care alongside the filter, tray and water passages. Continue routine cleaning and water changes. Low-water automatic shutdown is documented, but an owner should still check the actual water and operation.

The original EverSweet Max is a relevant alternative if hand washing and its coated tray are acceptable. The PETLIBRO PLWF116 is worth comparing when direct Wi-Fi intake records are the priority. Choose the Max 2 UVC for the specific combination of battery placement, its supplied pump and the named washable parts, while resolving any essential sensor-mode requirement for the exact delivered version.
