Petkit PuraMax 2 vs Purobot Ultra
PuraMax 2 ($299) has a 7L waste bin and 22 lb capacity. Purobot Ultra ($699) has UV sterilization, larger 12L waste bin, and advanced tracking. Choose PuraMax 2 for value, Ultra for premium features.
What litter for Petkit PuraMax 2
The PuraMax 2 works with all clumping litters. Dr. Jackson recommends low-dust clumping clay or mixed litter (like Petkit Mixed). Fill depth: 2-3 inches. Do not exceed 3 inches – sensors may misfire.
Intro
I used to scoop litter boxes three times a day.
With two cats, that’s 90 scoops per month. 1,080 scoops per year. My back hurt. My time disappeared. And I was tired of the smell.
Then I tried the Petkit PuraMax 2.
Now I empty the waste bin every 15 days. That’s it. No scooping. No smell. No back pain.
The PuraMax 2 is Petkit’s budget-friendly automatic litter box. At $299.99 (currently 35% off), it’s significantly cheaper than the $699 Purobot Ultra. But does it deliver?
I’m Ahashanul Hoque from AvailPet.com. Alongside Dr. Allona Jackson, DVM – a feline medicine specialist with 12 years of clinical experience – we’ve tested the PuraMax 2 for safety, usability, and value.

Best Litter Type & Fill Depth Guide (Dr. Jackson’s Recommendation)
This is one of the most searched setup questions. Here’s what actually works.
Compatible litters:
| Litter Type | Compatibility | Dr. Jackson’s Rating | Notes |
|---|---|---|---|
| Clumping clay | ✅ Yes | 4/5 | Most common, works well, but creates dust |
| Mixed litter (tofu + clay) | ✅ Yes | 5/5 | Lower dust, excellent clumping. Petkit Mixed recommended. |
| Crystal (silica gel) | ✅ Yes | 5/5 | Zero dust, but does not clump (still works – crystals absorb urine) |
| Walnut/plant-based | ✅ Yes | 4/5 | Biodegradable, but tracks more than clay |
| Non-clumping | ❌ No | 0/5 | Will not work – waste bin will be wet and messy |
Fill depth recommendation:
- Optimal depth: 2-3 inches
- Do not exceed: 3 inches (sensors may misfire and cleaning cycle may fail)
- Do not go below: 1.5 inches (waste may stick to the bottom)
Dr. Jackson’s note: *”The PuraMax 2 works with all clumping litters, but I recommend low-dust options. Standard clay litter creates dust that can coat the sensors over time, leading to false readings. Petkit’s own Mixed Litter or a high-quality crystal litter are excellent choices. And remember – 2-3 inches only. Too much litter and the sensors won’t work properly.”*
Dr. Jackson’s Safety Review
As a veterinarian, safety is my first concern with any automatic litter box. Here’s my assessment of the PuraMax 2.
On the 7 Infrared + 4 Weight Sensors
“This is the most comprehensive sensor array I’ve seen in a litter box under $300. The combination of infrared (detects cat presence) and weight sensors (detects cat inside) provides redundant safety. If one system fails, the other should still stop the cleaning cycle. This is genuine peace of mind.”
On the 22 lb Weight Limit
*”Most automatic litter boxes max out at 15-18 lbs. The PuraMax 2’s 22 lb limit means it can accommodate Maine Coons, Norwegian Forest Cats, and other large breeds. However, kittens under 6 months should not use any automatic litter box – their weight may not trigger sensors reliably, and they need to be observed during litter training.”*
On the Low 7.87 Inch Entry
“This is a significant design win for senior cats with arthritis. Many automatic litter boxes have high entries that are painful for older cats to climb into. The PuraMax 2’s low entry reduces joint strain and keeps senior cats using the box instead of finding alternative spots.”
On the Anti-Pinch Structure
“The entrance staying open during cycling is a critical safety feature. Some cheaper automatic litter boxes close the entrance during cleaning, which can trap a curious cat. Petkit got this right – the entrance never closes, so your cat cannot be trapped inside.”
Critical Warning About Carpet Placement
“Do not place the device on carpets or mats as this may interfere with the sensors. This is not a suggestion – it’s a requirement from the manufacturer. Carpet can cause false sensor readings and malfunctions. The weight sensors need a flat, hard surface to work correctly. Place this litter box on tile, hardwood, or vinyl – never on carpet.”
Real Owner Review Analysis
Synthesized from 448 reviews (4.2 average rating):
What Owners Love
“Empty the waste bin every two weeks. Game changer. I used to scoop daily. Now I forget the litter box even exists.”
“My 18 lb Maine Coon fits comfortably. I was worried about the size, but the 76L interior is plenty big.”
“The app tells me which cat used the box and when. I have three cats. Now I know who’s going and how often. Caught a UTI early because one cat’s frequency dropped.”
“No smell. The sealed waste bin works. I was skeptical about the N50 2.0 odor remover, but my apartment doesn’t smell like cats anymore.”
Common Complaints
“Setup was confusing – accessories were hidden in the waste bin. I almost returned it because I thought parts were missing. Read the manual carefully.”
*”Wi-Fi setup was frustrating (2.4GHz only). My router uses 5GHz. I had to dig into settings to enable 2.4GHz.”*
“One of my cats is scared of the cleaning cycle. She runs away when it starts. She still uses the box, but she’s nervous.”
Setup Guide (Step-by-Step)
Follow these steps exactly. Most setup problems come from missing one of these.
Step 1: Unbox and find accessories
Pull out the waste bin. Accessories are packed inside. This is the #1 confusion point.
Step 2: Place on flat, hard floor
Never on carpet. This is critical for sensor accuracy. The product page explicitly warns against carpet placement.
Step 3: Add litter (2-3 inches deep)
Use clumping litter only. Do not exceed 3 inches. Do not go below 1.5 inches.
Step 4: Install N50 2.0 odor remover
This is the dual odor control system. Find the compartment (check the manual) and insert the N50 2.0 cartridge.
Step 5: Connect to 2.4GHz Wi-Fi only
If your router broadcasts both 2.4GHz and 5GHz, temporarily disable 5GHz during setup. This is the #2 confusion point.
Step 6: Run a test cycle
Use the app or the manual button. Watch the mechanism. Make sure it cycles smoothly.
Step 7: Introduce your cat slowly
Keep the old litter box nearby for 7 days. Let your cat choose. After a week, remove the old box.
PuraMax 2 vs Purobot Ultra
| Feature | PuraMax 2 | Purobot Ultra |
|---|---|---|
| Price | $299.99 | $699 |
| Waste bin | 7L (15 days) | 12L |
| UV sterilization | ❌ No | ✅ Yes |
| Weight limit | 22 lbs | 22 lbs |
| Entry height | 7.87 inches (low) | Standard |
| App tracking | Basic (usage data) | Advanced (health trends) |
| Odor control | Sealed bin + N50 2.0 | Sealed bin + UV + N50 3.0 |
| Best for | Budget, seniors, value | Premium features, health monitoring |
Verdict: Choose the PuraMax 2 if you want the best value under $400. Choose the Purobot Ultra if you need UV sterilization (for odor control) or advanced health tracking.
If you’ve decided the PuraMax 2 is right for your cat, don’t wait. The 35% discount ($299.99 vs $459.99) won’t last forever.
Troubleshooting Common Problems
| Problem | Solution |
|---|---|
| Sensors not working | Ensure the litter box is on a flat, hard floor (not carpet). This is the #1 cause of sensor issues. |
| Wi-Fi won’t connect | Switch to 2.4GHz network. Temporarily disable 5GHz on your router during setup. |
| Cat won’t use it | Keep the old litter box nearby for 7 days. Transition slowly. Add a scoop of old litter to the new box. |
| Odor still present | Check the N50 2.0 odor remover – it may need replacement (lasts 30-60 days). |
| Cleaning cycle stops mid-cycle | Check for obstructions (litter clumps stuck). Ensure waste bin is seated properly. |
| Litter sticking to bottom | Fill depth is too low. Maintain 2-3 inches of litter. |
| Cleaning cycle runs when cat is inside | This should not happen with 11 sensors. If it does, contact Petkit support immediately – safety issue. |
Final Verdict
Who Should Buy the PuraMax 2
- ✅ Multi-cat households – 76L large interior and 7L waste bin handle multiple cats
- ✅ Owners with senior cats – 7.87 inch low entry reduces arthritis pain
- ✅ Large breed owners – 22 lb limit fits Maine Coons, Norwegian Forest Cats
- ✅ Budget-conscious buyers – $299.99 on sale is excellent value
- ✅ Owners who travel – 15-day waste bin means no scooping while away
Who Should Skip the PuraMax 2
- ❌ Owners who want UV sterilization – buy the Purobot Ultra ($699)
- ❌ Homes without 2.4GHz Wi-Fi – you cannot use the app features
- ❌ Kittens under 6 months – too small for sensor detection
- ❌ Owners who want stainless steel – this is plastic construction
Dr. Jackson’s Final Word
“The PuraMax 2 is the best value automatic litter box I’ve reviewed under $400. The safety features – 7 infrared sensors plus 4 weight sensors – exceed what I typically see at this price point. The low 7.87 inch entry is a genuine win for senior cats with arthritis.
*Just remember the three non-negotiables: flat, hard floor only (never carpet). Clumping litter only (2-3 inches deep). And 2.4GHz Wi-Fi only.*
If you follow those rules, this litter box will save you hours of scooping and keep your home smelling fresh.”
