The Petkit Pura Max 2 makes a bold claim: all the convenience of the Litter-Robot 4, quieter operation, and £200 less. After 8 weeks of testing with two cats in a Manchester flat, we can tell you which parts are true — and which bits the marketing glosses over.
The real question isn’t “Does it work?” — it does.
It’s: “Does saving £200 justify the trade-offs in warranty and support?”
Let’s break down what this self-cleaning litter tray gets right, where it falls short, and whether it’s the smart buy for UK cat owners in 2026.

How It Works (In Real Life, Not Marketing Language)
The Petkit Pura Max 2 is a rotating-drum automatic litter box. Your cat enters the spacious 76L cylinder, does their business, exits, and sensors trigger a cleaning cycle. The drum rotates, sifting clean litter through a mesh screen while dropping waste into a sealed 7L drawer below.
✔ You don’t scoop
✔ You don’t smell it
✔ The app tells you when the drawer is full — no guesswork
With two cats, we emptied the waste drawer every 5–6 days. With one cat, most owners report 7–9 days between emptying (Petkit claims 10–15 days in their lab testing, though that’s optimistic in warmer weather).
What UK Owners Say About the PETKIT Pura Max 2
Feedback from UK owners of the PETKIT Pura Max 2 is generally very positive, especially from people living in flats or smaller homes. Many report a noticeable improvement in odour control compared to traditional litter trays, with several saying it makes multi-cat households much easier to manage.
Ease of daily use is another recurring theme. Owners frequently describe the automatic cleaning cycle as a meaningful time-saver, and many cats appear to adapt quickly to the system once introduced properly.
That said, some users mention a few practical downsides. Initial Wi-Fi setup can be frustrating for less technical owners, and opinions on the built-in deodorising spray are mixed, with some preferring to disable it. A smaller group of long-term users report occasional mechanical issues after extended use, although warranty support typically resolves these problems.
Overall, most UK owners view the PETKIT Pura Max 2 as a convenient upgrade over manual litter boxes, particularly for improving cleanliness and reducing everyday maintenance.
Key Features That Actually Matter
✅ 1. Automatic Self-Cleaning
No daily scooping. The cleaning cycle takes around 2 minutes and is noticeably quieter than the competitors we tested. The Pura Max 2 topped our quietest automatic litter boxes ranking — ideal for bedrooms and small UK flats. The rotation produces a gentle hum, quieter than a washing machine on spin cycle.
✅ 2. 360° Sealed ShieldBase (NEW in Pura Max 2)
This is the biggest upgrade from the original Pura Max. The entire drum base is now sealed to prevent urine leakage — Petkit’s solution to the leaking issues some owners reported with the first generation. Even cats that urinate high up on the walls or in elevated positions won’t cause leaks.
✅ 3. Three-Stage Odour Control
The Pura Max 2 attacks smells three ways:
- Sealed 7L waste bin with carbon filtration
- N50 2.0 odour eliminator (replaceable cartridge)
- Smart Spray (optional add-on) — automatically sprays after each cleaning cycle
Even in a small UK flat, the typical “litter corner smell” is virtually eliminated. We found the sealed bin and N50 eliminator sufficient — the spray felt unnecessary and had an overpowering scent.

✅ 4. Works With Most Clumping Litters
Unlike some competitors, the Pura Max 2 comes with two interchangeable litter sifters:
- Fine mesh (grey) — for bentonite, mineral, and clay litters
- Large mesh (green) — for tofu, wood pellet, and mixed litters
This flexibility means you can use whatever litter your cat already prefers. We tested it with World’s Best, Cat’s Best Original, and Sanicat — all performed well, though World’s Best tracked slightly less.

✅ 5. Smart App with Real-Time Monitoring
The Petkit app provides:
- Waste drawer fill level
- Litter level alerts
- Individual cat weight tracking (can distinguish between cats)
- Usage frequency and duration
- Health insights (helps detect urinary issues early)
The app works well once set up, though initial WiFi pairing can be finicky (more on that in “Problems We Encountered” below). The good news? The unit works perfectly fine without WiFi in standard mode.
✅ 6. Large 76L Capacity
This is one of the largest automatic litter boxes on the UK market. The spacious interior comfortably fits cats up to 8kg (18 lbs), making it suitable for large breeds like Maine Coons or Ragdolls.
The low 20cm entrance height is helpful for senior cats or those with mobility issues.

Pros & Cons

Problems We Encountered (Real Testing Issues)
WiFi Setup Was Genuinely Annoying
Initial pairing took three attempts and required restarting our router. The app wouldn’t detect the unit despite following instructions perfectly. Once connected, it’s been stable — but that first hour tested our patience.
App Occasionally Loses Connection
About once every 10 days, the app shows “offline” despite the unit working normally. Closing and reopening the app usually fixes it. The unit continues cleaning automatically regardless of app status.
Spray Deodoriser Too Strong
We disabled the automatic spray feature after week two. The scent was more “cheap air freshener” than “fresh linen” and filled the entire flat. The sealed bin and N50 eliminator handle odour perfectly well without it.
Monthly Deep Clean Can Be Difficult
The rotating drum has more crevices where litter gets stuck compared to some competitor’s designs. Monthly cleaning takes about 15 minutes.
What Changes After You Own It (Real-World Impact)
Before Petkit Pura Max 2:
🔸 Scoop 2–3 times per day
🔸 Persistent litter smell in the flat
🔸 Litter tracking everywhere
🔸 Arguments about whose turn it is to clean
After Petkit Pura Max 2:
✅ Scoop: never
✅ Smell: 95% eliminated
✅ Maintenance: 5 minutes per week
✅ You stop thinking about the litter box entirely
The mental freedom is the real benefit. You don’t realise how much headspace litter management occupies until a machine handles it for you.
Time savings: Approximately 10 minutes per day eliminated = 61 hours per year not spent scooping.

Petkit Pura Max 2 Dimensions (Will It Fit in a UK Home?)
One of the most common questions: “How big is it, and will it fit in my flat?”
Exact dimensions:
- Width: 62 cm
- Height: 55.2 cm
- Depth (front to back): 53.8 cm
- Entry height from floor: 20 cm
- Internal cylinder: 48 cm diameter
The unit needs at least 5cm of clearance around it for proper rotation — don’t place it flush against walls.
📌 Good rule of thumb: If you have space for a small washing machine or a large bedside table, the Pura Max 2 will fit.
For small UK flats, it works best in a utility room, hallway corner, or bathroom with spare floor space. Worried about space? Check our guide: Best Automatic Litter Boxes for Small UK Flats (coming soon).
Optional Accessories for the Petkit Pura Max 2
The base unit works standalone, but these add-ons improve the experience:
Petkit Waste Bags — Custom-fit drawstring bags that don’t bunch up. You can use regular bin liners (50–60L size), but these make weekly emptying cleaner. One bag lasts about 5–7 days with two cats. (~£30 for 90 bags on Amazon UK)
N50 2.0 Odour Eliminator Refills — Replaceable cartridges that last 2–3 months. They make a noticeable difference in small homes where odour control matters. (~£40 for 3-pack on Amazon UK)
Smart Spray Deodoriser — Automatically sprays after cleaning cycles. Works well but scent can be overpowering. Many owners (including us) disable it. (~£30 on Petkit UK)
Pura Air Purifier — Motion-activated ozone deodoriser. More effective than the spray but sold separately (arguably should be built-in at this price point). (~£25 on Petkit UK)
Entrance Fence — Reduces litter scatter and prevents tracking. Worth considering if your cats are enthusiastic diggers. (~£15 on Amazon UK)
You don’t need any accessories for the robot to function, but the N50 refills and custom bags genuinely improve the experience.

Total Cost of Ownership (Year 1)
Understanding the full cost helps you compare properly to alternatives:
Petkit Pura Max 2:

- Waste bags: ~£60/year (if using official bags)
- N50 eliminators: ~£80/year (6 replacements @ £13 each)
- Spray refills: ~£30/year (if using — we didn’t)
- Total Year 1: £619–£849
Litter-Robot 4 for comparison:
- Unit: £749
- Waste drawer liners: ~£50/year
- Carbon filters: ~£40/year
- Total Year 1: £839
The Petkit saves you roughly £50–220 in year one depending on which bundle you choose. Over three years, savings compound to £150–400+.

Petkit Pura Max 2 FAQ (UK Buyers)
Does the Petkit Pura Max 2 need special bags?
No — you can use regular kitchen bin liners (50–60L size works well), but custom Petkit bags fit perfectly and don’t collapse into the drawer. Most owners use the official bags for convenience.
How long do the N50 odour eliminators last?
The N50 2.0 cartridge lasts around 2–3 months depending on how many cats you have. For maximum freshness in small spaces, the refills are worth the investment.
Does it come with a ramp?
No — there’s no ramp included, and most cats don’t need one. The 20cm entrance is lower than most standard litter boxes. Only consider a ramp if you have very senior cats or those with severe mobility issues.
Is the Petkit Pura Max 2 worth it in the UK?
If you have 2+ cats or a large cat, and value quiet operation over premium brand support, it’s absolutely worth considering. The combination of effective cleaning, excellent odour control, and £200+ savings vs Litter-Robot 4 makes it strong value for 2026.
How often do you empty the waste drawer?
For one cat, expect to empty every 7–10 days. For two cats, every 5–7 days. For three cats, every 3–5 days. The app sends alerts when it’s 90% full.
Is the Petkit Pura Max 2 loud?
It’s one of the quietest automatic litter boxes we’ve tested. The cleaning cycle produces a gentle mechanical hum, similar to a bathroom extractor fan or dishwasher on quiet mode. You can comfortably run it at night without disturbing anyone.
Will my cat be scared of it?
Most cats adapt within 24–48 hours. UK reviewers consistently report faster adaptation than with Litter-Robot due to the larger entrance and quieter operation. Leave it unplugged for the first day so cats can explore without movement.
Can kittens use the Petkit Pura Max 2?
Not until they weigh at least 1.5kg (3.3 lbs) — the sensors won’t detect lighter weights reliably. If you have both kittens and adult cats, enable “Kitten Protection Mode” in the app to disable automatic cleaning until all cats reach the minimum weight.
Does it work with crystal litter?
No — only clumping litters. Crystal litter doesn’t clump and will fall through the sifter mesh. Stick to bentonite, tofu, wood, or mixed clumping litters. Learn more in our guide: What Litter Works Best with Automatic Litter Boxes?
Can the Petkit Pura Max 2 run without WiFi?
Yes — automatic cleaning works perfectly without WiFi. You’ll just lose app notifications, remote control, and health tracking until reconnected.
What happens if the power goes out?
The unit pauses mid-cycle and resumes when power returns. Waste stays sealed in the drawer — nothing overflows or leaks.
How does the 360° seal work?
The ShieldBase design means the entire bottom of the rotating drum is sealed with waterproof materials. Even if your cat urinates high up on the cylinder wall, liquid can’t escape underneath. This addresses the most common complaint about the original Pura Max.
What’s the warranty like?
1 year manufacturer warranty covering mechanical failures and defects. Some retailers (like Amazon UK) may offer extended protection plans. The 1-year warranty is shorter than Litter-Robot’s 2 years, which is worth considering if long-term support matters to you.
Final Verdict
The Petkit Pura Max 2 delivers where it matters most: genuinely quiet operation, effective odour control, and £200 savings vs the Litter-Robot 4. The trade-off is a shorter warranty and inconsistent customer service experiences. If you’re comfortable with that risk for the savings, it’s excellent value. If you want guaranteed long-term support and premium build quality, spend the extra £200 on the Litter-Robot 4.
Both eliminate scooping effectively. Your choice comes down to budget vs peace of mind.
For our household, the Pura Max 2 has performed brilliantly for 8 weeks. The WiFi setup frustration was a one-time annoyance, and the quieter operation makes it less intrusive than the Litter-Robot in our small flat. Whether the motor holds up for 2+ years remains to be seen — but at £200 less, even replacing it after 18 months would still be cheaper than buying a Litter-Robot upfront.
