Why it matters

The PuraMax 2 has a 76 L interior and takes cats from 3.3 to 22 lb; PETKIT says not to use it for pets under six months. Seven infrared sensors and four weight sensors pause the cycle when a cat approaches, and an anti-pinch structure guards the opening.

The 7 L waste bin holds up to 15 days of waste, per PETKIT. It works with any clumping litter, recognizes cats by weight, and runs auto, manual, timer and empty modes from the PETKIT app over 2.4 GHz Wi-Fi. An N50 odor eliminator and a roll of 20 bags come in the box.

Who it's for, and who should skip it

Good fit if

  • Multi-cat homes
  • Owners away for days at a time
  • Cats up to 22 lb

Look elsewhere if

  • Homes without a level spot near an outlet
  • Cats that are afraid of moving parts
  • Kittens under the maker's minimum weight

Pros and cons

Pros

  • 76 L interior
  • 7 IR plus 4 weight sensors
  • Up to 15 days per bin

Cons

  • 2.4 GHz Wi-Fi only
  • Not for pets under 6 months
  • Proprietary bag size

Limitations to weigh

  • Set it on a hard, level floor near an outlet. Weight sensors read wrong on carpet or uneven tile, which can stop or trigger cycles.
  • Automatic cycling has a minimum cat weight; keep automatic mode off for kittens under it and run cleans manually.
  • Empty the waste bin before it's full and keep spare bags; an overfull bin is the most common cause of a stalled cycle.
  • Running costs come from the bags, liners, filters and litter the maker specifies. The compatibility checker lists refills that state they fit.
