Neakasa M1 Review UK (2026) – Best Open-Top Litter Box for Anxious Cats?

If your cat refuses enclosed litter robots, the Neakasa M1 might be the only automatic litter box they’ll actually use. The open-top design eliminates the claustrophobia that stops anxious cats from using traditional automatic litter boxes — and at £359, it’s £390 cheaper than some of its closed-top competitors.

After 8 weeks of testing with two cats in a Manchester flat (one anxious British Shorthair, one confident tabby), we can tell you whether this budget-friendly open-top automatic litter box delivers — and where it falls short.

The question isn’t “Does the open-top work?” — it does brilliantly.

It’s: “Can a £359 automatic litter box compete with models costing twice as much?”

Let’s break down what this open-top automatic litter tray gets right, what needs improvement, and whether it earns its place as our #3 pick for UK cat owners in 2026.

Neakasa M1 Review UK: Is This Open-Top Litter Box Worth £359?

After 8 weeks of testing with two cats in a UK flat, the Neakasa M1 delivers on its core promise: anxious cats that refuse enclosed automatic litter boxes will use this one. The 43cm wide open-top design eliminates claustrophobia completely, and at £359, it’s cheaper than comparable closed-top models.

However, the trade-offs are real. Odour control is noticeably weaker (70% reduction vs 90%+ with enclosed models), litter tracking is the worst of our top 3 picks, and the app feels more like a shopping tool than a pet care tool. The unit also stops working entirely when the waste bin hits 90% full, unlike competitors that just send alerts.

The verdict: If your cat’s anxiety is the main issue, this solves it brilliantly. If odour control and minimal litter tracking matter more, spend extra one of our recommended top 3 closed-top litter trays.

Key Features That Actually Matter

✅ 1. Open-Top Design (The Main Selling Point)

This is why the Neakasa M1 exists. The 43cm wide opening means:

• No enclosed tunnel — perfect for anxious or claustrophobic cats
• Easy monitoring — you can see exactly what your cat is doing
• Natural feel — mimics traditional open litter trays
• No getting stuck — cats can exit from any angle during rotation (though rotation stops if detected)

Our anxious British Shorthair, who refused every enclosed automatic box we tested, used the M1 on day one. This alone justifies the design.

✅ 2. “Pull and Wrap” Waste System

The silicone waste drawer uses custom bags that seal with one pull — genuinely clever. You pull the drawstring, the bag wraps around the waste automatically, and you lift it out. No touching, no smell, no mess. Takes about 10 seconds total.

This beats the models with manual bag-tying or standard bin liner setup.

✅ 3. Large 11.23L Waste Capacity

One of the largest waste bins in any automatic litter box. For comparison

With two cats, we went 6–7 days between emptying. Single-cat households can genuinely stretch to 10–14 days.

✅ 4. Multi-Cat Weight Detection

The M1 features 5 pairs of infrared sensors and 4 weight sensors. It can:

• Detect cats weighing 1kg–15kg (2.2–33 lbs)
• Distinguish between multiple cats (when registered in app)
• Pause instantly if movement detected during cleaning
• Track usage frequency per cat

The weight tracking isn’t perfect, but it’s functional enough for basic health monitoring.

✅ 5. Neakasa Smart App

The app provides:

• Waste bin fill level
• Litter level alerts
• Individual cat tracking by weight
• Usage logs (time, duration, frequency)
• Remote cleaning triggers
• Cleaning schedule customisation

The downside: The app is quite pushy with marketing notifications. You’ll get frequent prompts to buy accessories, join promotions, or rate the product. It’s annoying but doesn’t affect core functionality.

✅ 6. Quiet Operation

The cleaning cycle is noticeably quieter than the Litter-Robot 4 but slightly louder than the Petkit Pura Max 2. Think “bathroom extractor fan” rather than “mechanical grinder.” You can run it at night without disturbing light sleepers in the same room. See how it compares to its closest competitors in our full quietest automatic litter boxes roundup.

✅ 7. Works With Most Clumping Litters

Fast-clumping bentonite, tofu-based, or mineral litters work best. We tested it with World’s Best, Cat’s Best Original, and Sanicat — all performed well, though World’s Best tracked slightly less.

✅ Pros

• Open-top design perfect for anxious, large, or claustrophobic cats
• Extremely easy setup (10 minutes, no tools required)
• “Pull and Wrap” waste system is genuinely brilliant
• Large 11.23L waste capacity (6–14 days between emptying)
• Cheaper than competing top models
• Detachable bowl makes deep cleaning simple
• Compact round footprint fits in corners
• Works well with most clumping litters
• Most cats adapt immediately (no acclimation period)

❌ Cons

• Odour control is less than in closed-top models. If your litter box is in your living room, you’ll notice.

• Litter tracking is the worst of all three top picks. Even with the included mat, expect litter 1–2 meters around the unit. Budget £35 extra for the pedal step or accept constant sweeping.

• App feels like a shopping tool, not a pet care tool. Constant notifications about sales, accessories, and promotions. You can disable some, but it’s annoying compared to competitor’s apps.

• Unit stops working completely when waste bin hits 90% full — unlike competitors that just send alerts. If you’re away for the weekend and miscalculate, your cats have no litter box.

• Only 1-year warranty

• Higher entrance may require step for senior cats

What Changes After You Own It (Real-World Impact)

Before Neakasa M1:

🔸 Scoop 2–3 times per day
🔸 Constant litter smell in bathroom
🔸 Anxious cat avoiding enclosed boxes
🔸 Litter tracked throughout the flat

After Neakasa M1:

✅ Scoop: never
✅ Smell: Significantly reduced
✅ Anxious cat uses it confidently
✅ Litter tracking: slightly worse than closed-top models (but worth it for cat acceptance)
✅ Maintenance: 10 minutes per week

The main benefit is cat acceptance. If your cat refuses enclosed automatic boxes, this solves that problem completely. The trade-off is managing litter scatter and odour more actively.

Time savings: Approximately 18 minutes per day eliminated = 110 hours per year not spent scooping.

Neakasa M1 Dimensions (Will It Fit in a UK Home?)

One of the most common questions: “How big is it, and will it fit in my bathroom?”

Exact dimensions:

• Width: 58 cm
• Height: 56 cm
• Depth (front to back): 55 cm
• Opening diameter: 43 cm
• Entrance height from floor: ~25 cm

The round footprint actually makes it more compact than you’d expect. It fits better in corners than rectangular models like the Petkit.

📌 Good rule of thumb: If you have space for a large laundry basket or a small circular side table, the Neakasa M1 will fit.

For very small UK flats or studio bathrooms, measure carefully — the 58cm width is manageable but not tiny.

Total Cost of Ownership (Year 1)

Understanding the full cost helps you compare properly:

Neakasa M1:

• Unit: £359–£449 (depending on sales/bundles)
• Waste bags: ~£55/year (6 refills @ £9 each, or use generic liners for ~£20/year)
• Total Year 1: £449–£499 (with official bags) or £414–£464 (with generic liners)

Comparison:

• Petkit Pura Max 2 Year 1: £619–£849
• Litter-Robot 4 Year 1: £839

The Neakasa saves you £170–£390 in year one compared to competitors. Over three years, savings compound to £310–£740+.

Who Should Buy the Neakasa M1?

✔ Owners of anxious, claustrophobic, or skittish cats
✔ Large cat breeds (Maine Coons, Ragdolls, Norwegian Forest Cats)
✔ Budget-conscious buyers wanting automatic cleaning under £450
✔ Multi-cat homes needing large waste capacity
✔ First-time automatic litter box buyers
✔ People who prioritise easy setup and cleaning
✔ Cat owners with open, well-ventilated spaces for the litter box

Who Should Skip It

✘ Small flats where odour control is critical. See automatic litter boxes with stronger odour control
✘ Anyone bothered by litter tracking (unless buying the pedal step)
✘ Homes with carpeted litter box areas
✘ People wanting premium build quality and warranty
✘ Owners of cats under 1kg
✘ Anyone who dislikes pushy app notifications

Final Verdict

The Neakasa M1 excels at its specific purpose: providing automatic litter box cleaning for cats that refuse enclosed designs. If your cat is anxious, claustrophobic, or simply prefers open spaces, this solves that problem brilliantly. The lower price makes it excellent value, and the “Pull and Wrap” waste system is genuinely clever.

However, the trade-offs are real. Odour control is weaker, litter tracking is worse, and the app experience feels budget-tier compared to competitors. If you need maximum freshness or have carpeted floors near the litter box, spend extra on an enclosed model.

For our household, the Neakasa M1 successfully converted our anxious British Shorthair who refused every other automatic box we tested. That alone justifies its place in our top 3. Whether the open-top design works for your specific situation depends on your cat’s personality and your home layout.
