The PETKIT PuraMax 2 is an automatic litter box for homes that want app controls, cat activity records and a sealed waste bin. It is a practical choice when you can place it on a flat hard floor, keep the entry clear and connect it to 2.4 GHz Wi-Fi.
Before deciding, check whether your cat is at least 6 months old and weighs between 3.3 and 22 lb. Also measure the 24.21 x 21.96 in footprint and the 7.87 in entry, then decide whether the app's records are useful enough to justify a connected box.
Is the petkit pura max a good fit for your home?
The petkit pura max is a strong match for a multi-cat household that wants automatic cleaning and app-based records. Its 76 L interior is designed for cats within the stated weight range, and the app records weight, toilet frequency and duration for recognized cats.
PETKIT PuraMax 2: Best for multi-cat app tracking
- 76 L interior
- 7 L waste bin
- 2.4 GHz app control
- 7 infrared and 4 weight sensors
A roomy automatic box with app controls, cat weight recognition and a sealed waste bin. Its flat-floor placement and 7.87 in entry deserve a careful check before buying.
Pros
- Tracks cat weight, toilet frequency and duration in the app
- Supports auto, manual, timer and empty modes
- Uses infrared and weight sensors to detect cats
- Works with clumping litter
Cons
- Must sit on a flat floor, not a carpet or mat
- Requires a 2.4 GHz connection for app control
- Not compatible with K3 Smart Spray
The PuraMax 2 combines auto-cleaning with auto, manual, timer and empty modes. The 7 L waste bin can hold up to 15 days of automatic scooping according to PETKIT, but that is a maximum, not a schedule to rely on without checking the drawer.
Choose it if you want to check working status remotely, set modes from a phone or keep track of changes in each cat’s usage. Skip it if you want a basic litter tray without an app, or if your only available location is carpeted.
The unit measures 24.21 x 21.96 x 21.96 in and weighs 22 lb. Plan for the box itself, the entrance, and enough clearance to reach and remove the waste drawer.
What does the PuraMax 2 include and how does it work?
The PuraMax 2 comes with an N50 2.0 odor remover, 20 trash bags, a litter sifter, a magnetic litter remover, decorative stickers, a quick start guide, a user manual and a US adapter. The accessories are packed inside the waste bin, so check there when unpacking.
Its sensors detect a cat inside or approaching the box. PETKIT says the unit pauses when a cat enters the detection area, and its anti-pinch structure keeps the entrance open.
This setup can reduce the need to scoop after each use, but it does not remove routine care. Check the bin and the surrounding floor, and watch your cat’s response as you introduce the new box.
The unit works with clumping litter. Follow the manual for loading litter and selecting modes, and avoid assuming that any litter type will work just because it fits physically.
Who should choose the petkit pura max?
Choose the petkit pura max if app tracking is a real benefit for your household. PETKIT says cats are identified based on weight, so records may be less useful if your cats have similar weights or if you do not want to monitor usage data.
The low-entry design may suit older cats, short-legged cats and cats with limited mobility. Still, 7.87 in is a step, so watch how your cat enters and exits before making this the only available box.
PETKIT says not to use this model for pets under 6 months. For kittens, use an age-appropriate alternative until they meet that restriction.
Who should skip the PuraMax 2?
Skip it if you need to set the box on a carpet or mat. PETKIT warns that those surfaces can affect the sensors and cause malfunctions, so a stable, flat hard floor is a requirement.
It may also be the wrong buy if your home Wi-Fi does not provide 2.4 GHz access and you want app control. The box still offers manual and timer modes, but connected records and remote settings need the app connection.
If the enclosure or opening seems intimidating to your cat, plan a gradual transition and keep the familiar litter setup available while your cat adjusts. Our guide on whether cats like self-cleaning litter boxes explains what to consider during that change.
How should you set up the PuraMax 2?
Set up the PuraMax 2 on a level hard floor with an unobstructed entrance. Measure the available area first, including the room needed to access the waste drawer, and keep the box away from doors or storage that could block your cat.
Connect it to a 2.4 GHz Wi-Fi network if you want app controls and usage records. If your router uses separate network names for 2.4 and 5 GHz, make sure your phone and box connect to the appropriate network during setup.
Follow the quick start guide and user manual to add litter and select a cleaning mode. Keep the box accessible while your cat learns the new location, and supervise the first uses so you can see whether the entry and cycle are comfortable for them.
Avoid placing a mat beneath the unit, even if you usually use one to catch litter. A separate mat can sit outside the box’s footprint if it does not interfere with the sensors or block the entrance.
How do you manage odor and waste?
The PuraMax 2 uses a sealed waste bin and N50 2.0 odor remover to help contain smells. PETKIT says the version reviewed here is not compatible with K3 Smart Spray, so don’t buy that accessory expecting it to work with this model.
Empty the drawer based on actual use rather than waiting for the maximum interval. More cats or heavier use can fill it sooner, and a full drawer may reduce the convenience of automatic cleaning.
PETKIT suggests replacing the waste liner twice weekly for two average-sized cats. Treat that as a starting point: inspect the bin, replace the bag when needed, and clean the surrounding area as part of regular care.
The included 20 bags offer an initial supply. For more, the PETKIT replacement pack has 100 drawstring liners designed for Pura X and PuraMax waste drawers.
These bags are not suitable for Purobot Ultra or Purobot Max Pro. Confirm the exact model before buying replacement liners, especially if you later switch to a different PETKIT box.
For cleaning the unit itself, follow our PETKIT PuraMax cleaning guide. Regularly checking the drawer, liner and surrounding floor makes it easier to catch a care issue before odor builds up.
Does the PuraMax 2 need Wi-Fi or an app?
The PuraMax 2 needs a 2.4 GHz connection for app control, working-status checks and cat usage records. Auto, manual, timer and empty modes are available, so the app’s value depends on whether remote settings and records matter to you.
The weight-based cat identification can be useful in a multi-cat home, but the records should be treated as a guide to routine, not a health diagnosis. If your cats are close in weight, verify that the app assigns their activity as you expect.
If you only want a box to run a chosen mode, the connected features may not change your decision. Our guide to Wi-Fi and automatic litter boxes explains which connected functions to weigh before buying.
How does the PuraMax 2 compare with the Purobot Max Pro 2?
Choose the PuraMax 2 for app-based activity tracking without a camera. Choose the Purobot Max Pro 2 if image-based monitoring is a priority and you have room for its different footprint.
The Purobot Max Pro 2 has an AI camera with a 210° viewing angle and IR night vision, plus an app that supports 2.4 and 5 GHz Wi-Fi. Its waste bin is 8 L, and the unit measures 25.87 x 21.18 x 23.74 in.
The camera and captured images may be more information than you need if your main goal is automatic scooping. For a comparison with another popular automatic box, read our PETKIT PuraMax 2 vs Litter-Robot 4 guide.
What mistakes should you avoid with the PETKIT PuraMax 2?
The most common setup mistake is placing the unit on a soft surface. Use a flat, hard floor and keep the entrance clear so the sensors can work as intended.
Another mistake is assuming the waste bin’s maximum interval applies to every household. Check the drawer regularly and replace the liner based on how quickly it fills, how many cats use it and whether odor escapes.
Don’t assume every PETKIT accessory fits every PETKIT model. The replacement bags are made for Pura X and PuraMax, while the PuraMax 2 version does not work with K3 Smart Spray.
Finally, don’t skip the transition period. Let your cat approach the box at their own pace, keep an eye on early use and confirm they can enter and exit comfortably.
Should you buy the petkit pura max?
Buy the petkit pura max if you want automatic cleaning and app records, have a cat at least 6 months old within its supported weight range, and can provide a flat hard-floor location with 2.4 GHz Wi-Fi. The 7.87 in entry and drawer access should also work in your room.
Choose the Purobot Max Pro 2 if camera monitoring matters more than a smaller footprint, or skip connected features if you prefer a simpler box. Before ordering, measure the setup area, check the floor surface and consider whether weight-based records will help you manage your cats’ routines.
