PetKit has been making waves in the automatic litter box space, and the Pura Max remains one of the most popular alternatives to the Litter-Robot. With the newer PuraMax 2 now available and the flagship Purobot Max Pro 2 sitting at the top of PetKit’s lineup, 2026 is an interesting time to evaluate what you’re actually getting for your money.
We’ve spent extensive time with the Pura Max ecosystem. Here’s an honest breakdown.
PetKit Pura Max: The Original
The PetKit Pura Max launched as PetKit’s answer to the Litter-Robot 4 — a rotating-drum self-cleaning litter box with app connectivity, odour control, and multi-cat support.
Specs at a Glance
| Spec | PetKit Pura Max |
|---|---|
| Capacity | 76-litre cylinder |
| Litter Bed | 16-inch square |
| Dimensions | 21" × 24" × 21" |
| Cat Weight Range | 1.5–18 kg (3.3–40 lbs) |
| Cleaning Cycle | Automatic rotating drum |
| Waste Container | Built-in with replaceable bags |
| App Control | Yes (PetKit app, Wi-Fi) |
| Odour Control | Air Purifier module (sold separately) |
| Safety Sensors | Weight sensor, infrared, anti-pinch |
| Price | ~$600–$700 CAD |
What We Like
The cleaning cycle actually works well. The rotating drum mechanism sifts clumps efficiently, and the waste bin seals reasonably tight. For a single cat, you can go 5–7 days between emptying the waste drawer. Multi-cat households (2–3 cats) should plan on every 2–3 days.
App integration is genuinely useful. The PetKit app tracks each cat’s usage frequency and body weight (via the built-in scale). Over time, you get a health log that can flag changes in litter box habits — a legitimate early warning sign for urinary issues. You can also trigger manual cleaning cycles, set schedules, and adjust sensitivity.
The form factor is more compact than the Litter-Robot. At 21 × 24 × 21 inches, it fits in tighter spaces than the Litter-Robot 4’s globe design. It’s not small by any means, but the boxy shape uses space more efficiently.
Safety sensors are robust. Weight detection pauses the cycle if a cat jumps in mid-rotation. Infrared sensors detect movement near the entrance. The anti-pinch system adds another layer of protection. We never felt unsafe using it.
What Could Be Better
Odour control is the weak point. Without the optional Air Purifier module (~$50 extra), smell management is mediocre. The sealed waste drawer helps, but it’s not airtight the way Litter-Robot’s drawer is. Reddit users consistently report about 60% odour elimination without the purifier, which tracks with our experience.
Cleaning the unit itself is a chore. The drum needs periodic deep cleaning, and the design makes full disassembly more involved than it should be. Plan on a thorough clean every 2–4 weeks depending on usage.
The waste bags are proprietary. PetKit sells replacement bags that fit the waste drawer. You can jury-rig standard bags, but the fit isn’t great. This is an ongoing consumable cost.
Wi-Fi connectivity can be flaky. The unit only supports 2.4 GHz Wi-Fi, and some users (including us, initially) had trouble with the setup. Once connected it’s stable, but the onboarding could be smoother.
Our Verdict on the Original Pura Max
At $600–$700 CAD, the original Pura Max delivers solid automated cleaning for single or small multi-cat households. It’s not perfect — the odour control and cleaning maintenance are real drawbacks — but it’s significantly cheaper than the Litter-Robot 4 ($900+ CAD) and does 80% of the job.

PuraMax 2: What’s New?
PetKit released the PuraMax 2 in early 2026 with a focus on improving the areas where the original fell short.
Key Upgrades
- ShieldBase 360° seal: The new seamless base design prevents urine from leaking along the edges of the drum — a common complaint with the original, especially with cats that spray high
- Improved litter pad: Can hold up to 2 litres of liquid, keeping the cylinder dry and reducing cleaning frequency
- Enhanced odour control: Triple-layer deodorization system (upgraded from the original’s basic system)
- Lower entry point: Better accessibility for kittens and senior cats
- Same footprint: Dimensions are virtually identical to the original, so it fits in the same space
Is the PuraMax 2 Worth the Upgrade?
If you already own a Pura Max and it’s working fine, probably not — the core cleaning mechanism is the same. But if you’re buying new, the PuraMax 2 is the one to get. The sealed base alone solves the most common complaint about the original.

How Does It Compare to the Litter-Robot 4?
We’ve reviewed the Litter-Robot 4 in depth, so here’s the quick comparison:
| Feature | PetKit Pura Max | Litter-Robot 4 |
|---|---|---|
| Price | ~$600–$700 CAD | ~$900–$1,100 CAD |
| Cleaning Method | Rotating drum | Globe rotation |
| Odour Control | Good (with purifier add-on) | Very good (sealed drawer) |
| App Quality | Good | Excellent |
| Cat Weight Tracking | Yes | Yes |
| Multi-Cat ID | Basic | Better (with Litter-Robot 4+) |
| Ease of Cleaning | Moderate | Easier |
| Footprint | Smaller | Larger |
| Waste Bags | Proprietary | Standard kitchen bags |
The Litter-Robot 4 is the better product overall, but the Pura Max offers 80% of the experience at 60–70% of the price. That’s a genuine value proposition, especially for first-time buyers testing whether automated litter boxes are worth the investment.
Who Should Buy the PetKit Pura Max?
Buy it if:
- You want automated litter box cleaning without paying Litter-Robot prices
- You have 1–3 cats under 18 kg
- You value compact design and app-based health tracking
- You’re willing to add the Air Purifier module for better odour control
Skip it if:
- You have very large cats (the entry and drum size may be tight)
- Odour control is your absolute top priority (Litter-Robot 4 is better here)
- You hate proprietary consumables
- You want fully hands-off operation (you’ll still need to clean the drum periodically)
The Bottom Line
The PetKit Pura Max earns its place as the best mid-range self-cleaning litter box in 2026. It’s not the cheapest option, but it’s significantly more affordable than the Litter-Robot 4 while delivering reliable automated cleaning, useful app features, and a compact design.
If you’re buying new today, go with the PuraMax 2 for the improved sealing and odour control. If you find the original Pura Max on sale under $500 CAD, that’s still a solid deal.
