PETKIT EverSweet 3 Pro UVC review

The PETKIT EverSweet 3 Pro UVC P4108 is a compact plug-in fountain with a stainless-steel reservoir and a plastic drinking tray. It suits a household that wants the included UVC pump, app flow controls and a relatively low body. The material distinction matters: its steel container does not make it the right match for someone whose essential requirement is a steel surface where the cat drinks.

Use the 1.6-liter figure for the working reservoir

The current US page specifies 1.6 liters of usable capacity. Its FAQ explains that 1.8 liters printed on packaging describes the maximum capacity instead. Those figures should not be treated as interchangeable when comparing minimum usable reservoir requirements. A household requiring at least 1.8 usable liters should select a model with that capacity actually established.

PETKIT separately describes sixty milliliters retained in the tray for a power interruption. That small accessible reserve is a useful construction detail, not a promise that the fountain can support a particular unattended period. The body is listed at 5.83 inches high. Allow space to lift off the wet components, handle the tray and reach the pump during cleaning.

A wireless pump still needs outlet power

The fountain requires continuous external USB power to operate its pump. The current US package excludes the adapter and specifies a five-volt, one-amp input. The pump receives power without an exposed internal cable, but there is no main operating battery. A buyer seeking a truly cordless drinking location should compare the Max 2 UVC with its different power conditions.

The wireless electrical pump remains part of the wet assembly. Removing the tank does not leave every electrical component in a dry motor base. That differs from designs in which the reservoir contains only wet mechanical parts. Check this construction separately from whether the product can be lifted off its powered base.

Two flowing modes and a scheduled pause

Normal mode circulates continuously. Smart mode circulates intermittently, with timing controlled through the app. Do Not Disturb stops pumping during a chosen period; it is a pause rather than a third style of flowing water. The original linked guide describes a default three-minute-on, three-minute-off interval.

The current UVC version has its own treatment cycle descriptions on the US product page. The older linked P4108 guide documents the underlying wireless fountain and its controls but predates that supplied pump description. Read the instructions that accompany the actual pump for its treatment behavior, especially when replacing an earlier pump.

Bluetooth control and remote-access conditions

The direct app connection is Bluetooth. It provides mode controls and device reminders, including water and filter status. That does not make the fountain a standalone Wi-Fi device. Remote interconnection is described through another compatible PETKIT main device within the specified distance, so check the exact bridging equipment before relying on remote control.

Do not confuse status alerts with individually measured drinking totals. The specific product information and linked guide do not establish an RFID reader or camera for attributing visits to different cats. Software profiles alone do not change the identification hardware. If individual attribution is important, compare the tag-based PLWF305 or camera-based Ultra on their own requirements.

Materials do not remove the cleaning workload

The US comparison identifies a 304 stainless-steel tank and an ABS drinking tray. Its care FAQ prohibits dishwasher cleaning of all parts. Separate the wet assembly from the electrical base and follow the pump's cleaning instructions. The included UVC feature and filter are additional components to care for; neither replaces washing accumulated residue from the tray and water passages.

The current FAQ suggests replacing the filter every four weeks. Check condition earlier when the water, debris or household use warrants it. A replacement schedule is not a guarantee that the reservoir remains clean between services. Low-water automatic shutdown is documented, but it remains sensible to inspect actual water level and pump operation.

Who should choose the compact Pro

Choose the 3 Pro UVC when a low plug-in body, a steel reservoir and the supplied treatment pump fit the household together. The Solo 2 offers a larger plastic reservoir and visible water-level window, while the Max 2 changes battery and dishwasher capabilities. Compare the specific drinking surface, usable capacity and power arrangement before choosing by the Pro name alone.
