PUROBOT MAX 3 · P9906 US listing
Covered-cylinder cleaning with a lower entrance and two sifter options.
Consider P9906 when entrance height and sifter choice matter. Budget for consumables and gentle pad care, and confirm the exact bundle. Manufacturer dimensions remain inconsistent. External MAX3 experiences add context on acceptance and odor, but their US P9906 identity has not been authenticated.
The UK reviewer reports easy setup, useful app logs and N50-assisted odor containment, with substantial cleaning work. MAX3 use covered about two weeks; older PuraMax 2 wear observations and exact US P9906 equivalence are excluded.

Covered rotating litter cleaning with local operation and optional connected history.
The PUROBOT MAX 3 belongs on the shortlist when a lower entrance and a choice of sifting screens are priorities. Its appeal should be judged alongside the cleaning instructions for the coated litter pad and the continuing supply of odor-control consumables. Editorial assessment. We would not select it by a headline noise number or publish a precise room-fit recommendation until conflicting dimensions are resolved.
The US listing identifies P9906, gives an 8.03-inch entrance, 7 L waste bin and 76 L cylinder space. That 76 L is chamber volume, not the amount of litter to pour in. It lists 2.4 GHz Wi-Fi and two screens: standard P99022 and finer honeycomb P99023. US product information.
The linked manual limits particles to 12 mm long and 3 mm diameter. Respect the MAX fill mark. Its operational restrictions exclude kittens under six months and cats below 1.5 kg; a kitten-related setting does not remove those restrictions.
Unplug before maintenance. Rinse the detached cylinder and sifter; gently wipe the pad, and keep the base wipe-only. Dry parts before assembly. The manual distinguishes Basic from Premium: Breezy and N60 are not included in Basic. Approximate replacement guidance is 30 days for N50 and 60 for N60. Manufacturer-linked manual.
Physical controls cover several routine actions; additional configuration is in the app. Whether automatic behavior persists through an internet outage needs separate confirmation. The recurring-cost comparison should include odor-control supplies and pad replacement where necessary, with bundle contents checked before pricing.
Editorial inference: A lower threshold may make access easier for some households, but it cannot establish comfort for an individual cat. Litter screens still require compatible particles. App access, gentle pad care and replacement supplies deserve as much attention as the initial device cost.
The US P9906 listing gives 620 × 538 × 552 mm W×D×H. Its linked manual covers P9906 and P9911 and gives 540 × 615 × 558 mm without specified axes. Treat exact room fit as unresolved. The listing also gives both 35 and 45 dB; a numeric noise verdict is not established. The manual describes a Continuous Rotation setting that changes response to an approaching cat, so approach detection should not be summarized as unconditional. Consult the current instructions for the exact device and settings.
Stiv at CoolCuration describes easy setup and useful app logs over roughly two weeks, with odor containment aided by N50. Deeper cleaning remained substantial work. This is a UK MAX3 account; its exact US P9906 equivalence is unconfirmed. Older PuraMax 2 wear observations are not MAX3 durability evidence.
Some selected owners report acceptance or clear preference. Other accounts describe lingering odor, missing odor-kit housing or cleanup around the entrance. These five selected accounts identify MAX3 by name but do not authenticate US P9906 labels. They highlight questions to check, not a measured success or failure rate.
The control panel handles several routine actions. PETKIT’s general litter-box FAQ says devices continue previous app settings when the network disconnects. The article does not name P9906, so we would confirm the exact device’s behavior before relying on it during an outage. PETKIT support FAQ.
