These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
PETKIT PuraMax 2 Self-Cleaning Cat Litter Box (P9902)
Adult-cat homes with a hard, uncarpeted floor and clearance from walls
The PuraMax 2 is PETKIT's rotating-cylinder automatic box with an OLED panel, a 7 L sealed waste bin and an N50 odor eliminator. PETKIT's manual says cats under six months or under 1.5 kg are not recommended, and a Kitten Mode turns automatic cleaning off entirely. It needs a hard floor, a gap from the wall and clumping litter within a stated particle size.
Published specifications
- Manual: model P9902, 620 x 538 x 552 mm (24.41 x 21.18 x 21.73 in), about 10 kg (22 lb)
- Manual: cats younger than six months and cats under 1.5 kg are not recommended; listing FAQ adds a 10 kg (22 lb) maximum
- Manual: rated input 12V 2A; Wi-Fi and BLE; listing states 2.4 GHz
- Manual: no litter particles longer than 1.2 cm or over 3 mm diameter; FAQ names clay, tofu and mixed clumping litter
- Listing FAQ: 7 L waste bin, up to 15 days for one cat by PETKIT's lab result; N50 replaced about monthly
- PETKIT warranty policy: 2 years for PuraMax 2 bought on or after 1 Jan 2025 from PETKIT or an authorized US distributor
Strengths
- PETKIT publishes a full manual, a warranty policy and a model-specific FAQ, all naming P9902 or T4-2
- Runs from an on-unit OLED menu, so filling, levelling and cleaning do not require the phone
- Maintenance table names each washable part, its cleaning method and when to replace it
Caveats
- Not recommended for cats under six months or under 1.5 kg, and Kitten Mode disables automatic cleaning
- PETKIT's own documents give two different wall gaps (5 cm and 10 cm) and two cat-weight floors (3.3 lb and 3.5 lb)
- Carpets and mats are ruled out by the listing as interfering with the sensors
