7 Best Petkit PuraMax Review Options Compared

⚡ Quick Verdict

📋 How We Evaluated

We checked cleaning cycle reliability, sensor response, and build quality on the unit itself. For accessories, we weighed fit, ease of installation, and how well each one solves a specific problem, odor, leaks, or hands-free disposal.

PuraMax vs PuraMax 2: Which Model Do You Have

PETKIT sells three related units, the original PuraMax, the PuraMax 2, and the Purobot Max Pro. Accessories are not interchangeable across all three. The trash bags and litter pad in this review fit the PuraMax 2 and Purobot Max Pro drawer only.

The original PuraMax needs its own pad, listed further down. Check your model number before ordering parts. The cylinder groove size changed between generations, so the wrong pad just gets returned.

Deciding between the two current models? Our Petkit Purobot Max Pro Review breaks down what actually changed between them.

What We Found

The 76L drum fits most cat sizes without crowding. A 7.87 inch entry sits low enough for older cats or ones with joint pain. The 360 degree ShieldBase seal is the reason this box does not leak or smell up a room.

Seven infrared sensors and four weight sensors handle safety, eleven total. The unit pauses the moment it detects a cat, then finishes the cycle once the cat leaves. The app logs toilet visits and weight over 2.4GHz WiFi, so you catch a health change early.

Build quality feels solid, and the cleaning cycle runs quiet enough for a bedroom.

Who It’s For

Best for multi-cat homes and owners who want app-based health tracking. Comparing it against other brands? Our Best Self Cleaning Litter Box roundup ranks the PuraMax 2 against seven other models.

What We Found

These liners are cut for the PuraMax 2 and Purobot Max Pro drawer, not the original PuraMax. HDPE plastic resists tears better than a generic kitchen bag.

The drawstring closes the bag in one pull, no knot tying with litter dust on your hands. Each pack holds 90 liners, about five rolls, enough for a multi-cat home to go months without reordering.

The opaque material hides the contents and blocks smell better than a clear bag would.

Who It’s For

Best for any PuraMax 2 or Purobot Max Pro owner who wants a clean, fast waste swap without buying the wrong size bags twice.

What We Found

This cartridge sits in the waste bin and neutralizes smell instead of masking it. Each piece lasts about one month, so three pieces per pack covers roughly a quarter.

The plastic casing is new since the last version, so you swap it without touching the contents. It is non-toxic, and installation just means popping off the silicone cover first.

Who It’s For

Best for owners who keep the litter box in a living room or bedroom. If odor is your main worry across any brand, our Best Automatic Litter Box for Odor Control guide covers more options.

What We Found

This mat replaces the factory pad in the PuraMax 2 and Purobot Max Pro cylinder. The 300D Oxford fabric has a waterproof coating, so urine sits on top instead of soaking through.

The elastic border is the real fix. It locks into the cylinder groove and stops liquid from creeping underneath, which was the main complaint with the older mat.

It resists scratches too, so claws will not shred it in a few weeks like a thin liner would.

Who It’s For

Best for owners dealing with edge leaks or a torn factory mat. Fits the PuraMax 2 and Purobot Max Pro only, not the original unit.

What We Found

This sprays a neutralizing mist after each cleaning cycle instead of sitting passively in the bin. It pairs over Bluetooth to the PETKIT app, so you can schedule sprays around your cat’s usual visit times.

A small LED lights the bin, useful if you check on the box at night. Mark-free adhesive means no screws or drilling to mount it.

Who It’s For

Best for owners battling odor in a small or closed-off room. Want more app-controlled options across brands? Check our Best Smart Litter Box for Cats guide.

What We Found

This pad is for the original PuraMax only, not the PuraMax 2. The waterproof fabric resists scratches, and it holds up better than the stock mat over time.

Installing it takes more steps than the newer snap-in pads. You empty the litter first, then secure the edges by hand.

Who It’s For

Strictly for original PuraMax owners replacing a worn or torn mat. If you own the PuraMax 2, get the Litter Pad Max above instead.

What to Look For Before Buying?

Choosing PuraMax accessories comes down to your model and your budget. I check three things first, sensor reliability, ongoing consumable costs, and whether the app data is worth the WiFi requirement.

Check Safety Sensor Reliability

Safety comes before convenience with any automatic box. Look for multiple infrared and weight sensors, the PuraMax 2 uses eleven. The cycle should pause the instant it senses movement, not after a delay. Test this during setup before trusting the unit unattended.

Value Ongoing Maintenance Costs

Trash bags, odor cartridges, and spray refills all add to the real cost of owning a PuraMax. Add up the monthly spend before buying, not just the sticker price of the box. Standard, easy to find refills save money over proprietary ones.

Rating App Functionality and Data

A useful app tracks visit frequency and weight without constant glitches. Check for regular app updates, an abandoned app is a bad sign. Remote schedule changes and cycle adjustments should not require a firmware update to work.

Verify Size and Accessibility

Measure the interior so your cat can turn around without bumping the walls. A low entry point matters most for senior cats or ones with joint pain. Measure your floor space too, the PuraMax 2 is not a small unit.

Frequently Asked Questions

Are automatic litter boxes safe for kittens?

Most manufacturers recommend waiting until cats are at least six months old or meet a minimum weight. Sensors may not detect very small kittens accurately, which is a safety risk. Check the user manual for exact age and weight guidelines.

How often should I change the waste bin liners?

For one cat, changing the liner twice a week works well. Multi-cat households may need to change them more often to control odor. Leak-proof liners make the swap faster and cleaner.

Do I need a special type of litter?

Most automatic boxes work best with clumping clay or plant-based litter. Skip non-clumping or heavy crystal litter, it can jam the sifting mechanism. Check the manufacturer’s recommendation before filling the drum.

Can I use the app without a WiFi connection?

Most smart features, including health tracking and remote control, need 2.4GHz WiFi. Without internet, the unit still runs its basic cleaning cycles. You just lose the data logs and remote status updates.

How do I deal with lingering odors?

Replace the waste liner on schedule and add an odor-neutralizing accessory like the N50 cartridge or a smart spray. Seal the waste bin properly after every cycle. Regular deep cleaning keeps smells from building up.

Is the PETKIT PuraMax 2 worth it?

Yes, if you have multiple cats or want health data over time. A single cat owner who does not mind scooping might save money with a manual box instead.

What is the difference between PuraMax and PuraMax 2?

The PuraMax 2 runs eleven sensors, more than the original, plus a different cylinder pad and drawer size. Accessories are not interchangeable between the two generations.

How long do PuraMax odor eliminators last?

The N50 cartridge lasts about one month per piece. A three pack covers roughly a quarter before you need to reorder.

🎯 Final Verdict

The PuraMax 2 is the pick if you want a self cleaning litter box that also tracks your cat’s health. Eleven sensors and the 360 degree seal handle safety and odor without extra effort.

Pair it with the drawstring waste liners and an N50 odor cartridge, and maintenance drops to a quick bag swap every few days.
