PETKIT EverSweet Solo 2: problems, parts and running costs

Checked: 2026-10-04

Summary

The most common issues owners report are floor overflow and a pump that stops moving water, usually traced to an impeller fouled by hair and biofilm. Expect to spend roughly $4-$8 per month on replacement filters. At $49.99 or less from PETKIT’s US store it is a reasonable buy for a single-cat household; above $60 the case weakens.

Common problems and fixes

Floor overflow — the most-cited complaint in marketplace review summaries; the fix is to check the base seal and keep the unit on a level surface. [9]
Pump stops pushing water — reported alongside overflow; the impeller can be fouled by hair and debris, so weekly cleaning is the workaround. [9]
Filter indicator keeps flashing after a new filter — you must complete a reset in the app or the light keeps blinking. [3]
Pump stops while lights and beeping keep working — reported on the sibling Solo SE model; the in-thread diagnosis is fur and bacterial buildup around the impeller. [15]
“Lack of Water” fault when the tank is not empty — reported on the 3 Pro and Max models; the cause is trapped air or limescale in the shared wireless pump design. [18]
Filter Unit 3.0 overflow and clogs — reported on an earlier PETKIT fountain model; one owner was told by PETKIT to cut out the filter’s centre section to stop overflow. [10]

Parts and consumables

Filter Unit 3.0 (P4161) — $19.99 for a 5-pack at PETKIT US (2026-10); replace every 2-4 weeks per PETKIT’s own guidance. [7]
Wireless Pump Replacement (P4113 / FFT1) — $15.99 sale price, $19.99 regular at PETKIT US (2026-10); the main wear part, orderable directly. [8]
Cleaning Set — $7.99 at PETKIT US (2026-10). [8]

Yearly running cost

Filters are the main recurring cost. At $19.99 for a 5-pack and a 2-4 week replacement interval, a typical owner spends roughly $4-$8 per month on filters. The wireless pump is a $15.99-$19.99 one-off replacement when it eventually fails. Electricity cost is negligible at 2 W rated power. No subscription is required.

When it is a good buy

$49.99 or less (PETKIT US, 2026-10): reasonable for a single-cat household that wants app control and a visible water-level window. [1][13]
$50-$60 (PETKIT US, 2026-10): still defensible, but there is no independent test data and the app is Bluetooth-only. [1][13]
Above $60: the case weakens — the 2 L tank is small, the plastic wet path is not dishwasher safe, there is no sterilization, and the warranty is 1 year. [2][3][5]

Alternatives:

PETKIT EverSweet 3 Pro or Max — better for multi-cat households or anyone who wants stainless steel and dishwasher-safe parts. [2]
PETKIT EverSweet Solo SE — cheaper, but has no app and a smaller 1.8 L tank. [2][14]
