Why it matters

WARCAT's 90 L drum takes cats from 2.2 to 24.2 lb. Dual infrared sensors, two sets of Hall-effect sensors and a microwave radar track motion and mechanism position to stop the cycle when needed.

The 8.6 L drawer gives up to 10 days of use, per WARCAT, and works with any bag 17.7 in or wider. An airtight cover holds odor, and a scented gel adds fragrance. The 2.4 GHz app schedules cleans and logs visits.

Who it's for, and who should skip it

Good fit if

  • Large cats
  • Budget buyers
  • Owners who prefer generic bags

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

  • 90 L drum
  • Wide weight range
  • Any 17.7 in+ bag

Cons

  • Scented gel
  • 2.4 GHz only
  • Tall at 23.4 in

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.
