Top complaints
PETKIT PuraMax 2 Self-Cleaning Cat Litter Box
- Small interior
Wirecutter says the PuraMax 2's interior is just as small as the Purobot Max Pro 2's, which was one of the smallest it tested. Cats.com says it may not suit large cats.
- Tedious deep-cleaning
Cats.com found the magnetic litter remover ineffective and deep-cleaning tedious, and says it is designed for hard floors only; on carpet the reviewer turned off auto-scooping and the weight sensor became inaccurate.
- Mixed odor control and durability
Amazon's review summary says odor control, durability and size get mixed reviews: some say it keeps smells away, while others say it doesn't control odor well. Value for money is also mixed.
Whisker Litter-Robot 5 Pro
- Buggy app and sensor errors
Wirecutter tested it for nearly two months and found the app controls extremely glitchy. BGR got frequent sensor errors (false 'extended scale activity' with no cat nearby) and motor issues, had to manually reset it about once a week, and saw the app show the wrong status and setup crash several times.
Source: Wirecutter, BGR review - Key features behind a subscription
Cats.com says the Whisker+ subscription ($7.99/month) is needed for real-time video, visual cat identification and up to two years of history; the free tier gives two days of video and five minutes of live view a day.
- Very expensive and still new
Cats.com lists it at $899 and flags the high price and possible new-model glitches. BGR found the camera more novelty than daily necessity.
