A popular mid-priced box on Amazon that Cats.com picks for odor control. But its interior is one of the smallest Wirecutter tested, deep-cleaning is tedious, and Amazon owners are split on odor and durability.
Top complaints
- 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.
What owners love
- Easy setup; cats take to it
Amazon shoppers say setup is quick, their cats took to it immediately, and it is easy to take apart for cleaning. They also like its safety features for pets and children.
- Sealed drawer and leakproof liner
Cats.com rates it best for odor control, citing a sealed waste drawer, a leakproof liner that performed well, two sifters and an easy app.
- Entrance stays open while cleaning
Cats.com notes 11 sensors, and the drum rolls back and forth so the entrance stays open during a cycle and a cat can't be trapped if sensors fail.
- You have a large cat
- The box will sit on carpet
- You hate fiddly deep-cleaning
- Small to average-size cats
- Hard floors
- A full-featured app without a camera
