A big part of my job as a pet tech writer is setting up automatic litter boxes and observing my cats, ahem, do their business. It’s not glamorous work, but someone’s gotta do it. After testing over a dozen, I’ve learned that not all are created equal.
I’ve been impressed with all of the automatic litter boxes that I’ve tested from Petkit, but the PuraMax 2 is the litter box that I recommend to most people. (For more Big Deal Days bargains, be sure to consult our guide to the Absolute Best Prime Day Deals for October 2025 and check in on our Prime Day liveblog, where we’re tracking deals and trends all event long.)
It’s the fairest price point for the quality of all I’ve tested. Regularly $500, it’s $150 off right now, making it well below the price point of many comparable models, like the Litter-Robot 4, which is regularly $700.
I can’t believe I’m going to say this, but the PuraMax 2 actually smells good. This box has triple odor control, a sealed waste bin, an odor eliminator attachment that sits in the waste bin, and a citrusy deodorizing spray that goes off after every cleaning and randomly throughout the day to ensure the litter box stays fresh.
The design of the large, forward-facing hole feels familiar to most cats, and both of my cats (including my large 17-pound tabby) took to this litter box easily. When it’s time to refill, the box rotates and the hole faces up to make litter filling easy with no awkward bending or refilling with smaller containers.
When the cat enters the box, their weight is displayed on the front, and the app logs every time it was used, for how long, when the cleaning cycle begins, ends, and when the deodorizing spray was emitted. Owners can also change settings manually via the buttons on the front.
