Leo’s Loo Too Review UK (2026) – Is the UV Light Worth the Premium Price?

The Leo’s Loo Too makes a bold promise: EPA-approved UV light that kills 99.9% of bacteria, voice control via Alexa, and whisper-quiet operation at just 30dB. At £550–£679, it’s positioned as a premium alternative to both the Litter-Robot 4 and Petkit Pura Max 2.

After researching extensive UK and US owner feedback and comparing specs against our tested models, we can tell you which marketing claims hold up – and which bits Casa Leo (formerly Smarty Pear) glosses over.

The real question isn’t “Does the UV light work?” – it does.

It’s: “Does a UV sterilisation system justify choosing this over proven UK favourites like the Petkit or Litter-Robot?”

Let’s break down what this California-designed tech gets right, where reliability concerns emerge, and whether it’s the smart buy for UK cat owners in 2026.

Is the Leo’s Loo Too Worth It? (Quick Answers)

How Leo’s Loo Too Works (Real-World UK Overview)

The Leo’s Loo Too is a rotating-drum automatic litter box with a covered dome design. Your cat enters through the 22cm (8.5in) opening, uses the flexible rubber-lined drum, and exits. Advanced radar, weight sensors, and anti-pinch sensors detect when they leave and trigger a cleaning cycle 3–7 minutes later (adjustable).

The drum rotates slowly, sifting clean litter through a perforated screen while dropping waste into a 9.5L sealed drawer below. After waste is deposited, an EPA-approved UV-C light automatically treats the waste drawer, killing 99.9% of bacteria and reducing odours.

✓ You don’t scoop
✓ UV light sanitises automatically
✓ The Casa Leo app sends alerts when the drawer needs emptying

With one cat, most owners report emptying the drawer every 7–10 days. With two cats, expect every 5–7 days. Casa Leo’s claim of “2 weeks for multiple cats” is optimistic unless you’re using very little litter.Want to understand how UV sterilisation compares to traditional odour control? See our guide: How

What UK Owners Say About Leo’s Loo Too

Feedback from UK owners of Leo’s Loo Too is mixed but informative. Many people living in flats highlight strong odour control as one of the biggest benefits, with the sealed waste drawer and internal sanitising features helping keep smells contained between emptying.

Owners also frequently mention that setup is straightforward and that most cats adapt within a few days. The cleaning cycle is generally described as quiet enough not to disturb daily life, which is an important factor for smaller homes.

However, some users point out design limitations. The entrance size can be restrictive for certain cats, and proper positioning during use is important to avoid mess. A minority of long-term owners report mechanical reliability concerns after extended use, with warranty support experiences varying depending on the situation.

Overall, UK buyers tend to see Leo’s Loo Too as a feature-rich automatic litter box with excellent odour control, but one that requires careful consideration of space, cat size, and long-term durability expectations.

Key Features That Actually Matter

✅ 1. EPA-Approved UV-C Light Sterilisation

This is the Leo’s Loo Too’s signature feature and what sets it apart from competitors. The UV-C light automatically treats the waste drawer after every visit, intermittently throughout the day, and on-demand via the app.

What it does:

• Kills 99.9% of bacteria in the waste drawer
• Reduces odours at the source rather than just masking them
• EPA-approved technology (not just marketing claims)

Real-world impact: Owners consistently report better odour control than standard automatic litter boxes. The UV system genuinely makes a difference in small UK flats where every bit of odour reduction matters.

The catch: UV light treats the waste drawer, not the litter itself. It’s effective but not magic – you’ll still need carbon filters and regular cleaning.

✅ 2. Whisper-Quiet Operation (30dB)

The Leo’s Loo Too operates at approximately 30dB – genuinely the quietest automatic litter box we’ve researched. For context:

• Leo’s Loo Too: 30dB (whisper)
• Petkit Pura Max 2: ~35dB (very quiet)
• Litter-Robot 4: ~45dB (moderate hum)

You can run cleaning cycles at night in the same room without disturbing light sleepers. Several UK flat-dwellers specifically praise this feature.

✅ 3. Casa Leo App with Voice Control

The Casa Leo app (iOS/Android) provides:

• Real-time waste drawer level alerts
• Individual cat weight tracking (weight sensors detect cats 0.9kg+)
• Usage logs (frequency, duration, timing)
• Remote manual cleaning triggers
• Alexa and Google Assistant integration

Voice commands work well: “Alexa, ask Leo’s Loo to start cleaning” genuinely functions. This matters if your hands are full or you’re in another room.

App quality: Better than the Neakasa M1’s pushy marketing app, but not quite as polished as the Litter-Robot 4’s Whisker app. Connection is generally stable once set up.

✅ 4. Triple-Layer Safety System

Safety features include:

1. Radar Detection System – Creates a protective “wall” around the drum; stops rotation if anything approaches
2. Four Weight Sensors – Detects when cat enters/exits; won’t start cleaning with cat inside
3. Anti-Pinch Sensor – Stops rotation if waste drawer encounters resistance

Real-world performance: The radar system is impressively sensitive. Several owners report it stopping when they walk past, not just when cats approach. This is safety-first design, though it occasionally means interrupted cleaning cycles.

✅ 5. Compact Footprint (for UK Homes)

Dimensions: 61cm W × 56cm D × 70cm H (24″ × 22″ × 27.6″)

This is more compact than the Litter-Robot 4 and similar to the Petkit Pura Max 2. The round base fits well in corners, and the smaller footprint works better in UK bathrooms and utility rooms.

Entry height: 20cm from floor (similar to competitors), suitable for most cats but may need a step for seniors.

✅ 6. Larger Waste Drawer Capacity

The 9.5L waste drawer is approximately 6% larger than the Litter-Robot 4’s drawer, meaning slightly less frequent emptying. For single-cat households, expect 7–10 days; for two cats, 5–7 days.

The drawer uses custom-fit liners (£15 for 25 bags), though standard 50–60L bin liners also work if you don’t mind less precise fit.

✅ 7. Four Colour Options

Unlike most automatic litter boxes limited to white or grey, the Leo’s Loo Too comes in:

• Leo Grey
• Baby Blue
• Avocado Green
• Pretty Pink

For UK homes where the litter box lives in visible areas, colour choice matters. The softer palette blends better than stark white in modern interiors.

Pros & Cons

Problems Reported (Real Owner Experiences)

In short: Long-term reliability is the main issue — common reports include motor failures, stuck clumps, and slow customer service response times after 12 months.

Small Entrance Causes Positioning Issues

The 22cm (8.5in) entrance is smaller than competitors. Several UK and US owners report cats struggling to turn around, leading to urination at the front of the unit or outside the box entirely.

Some UK owners report that the entrance size of Leo’s Loo Too can be difficult for more cautious or skittish cats. A small number say their cats never fully adapted to turning around inside the unit, leading to inconsistent use. In comparison, those same owners sometimes find that alternatives like the Litter-Robot 4, with a wider opening, are easier for their cats to use comfortably.

Impact: Urine gets into the electronic panel, waste drawer compartment, and weight sensors – all areas not designed for liquid exposure.

Motor and Mechanical Failures After 12+ Months

Multiple owners across review platforms report motors failing, drums stopping mid-rotation, or units becoming completely non-functional after 12–18 months of use.

Common complaints:

• Grinding noises during rotation
• Unit stopping completely
• Repeated cleaning cycles (malfunctioning sensors)
• Weight sensors failing to detect cats

Example: One UK owner reports that after roughly a year of use, their Leo’s Loo stopped working and a warranty claim became a frustrating process. According to their experience, communication with the manufacturer was slow and the situation ultimately left them dissatisfied with how the warranty was handled. They describe the experience as disappointing, especially given the product’s premium price.

Customer Service Quality Varies Dramatically

Experiences range from “excellent and responsive” to “weeks-long delays and refused warranty claims.”

Positive experiences: Some owners report helpful support teams that quickly replaced faulty units.

Negative experiences: Others describe 2+ week response times, warranty disputes despite units failing within coverage period, and accusations of customer misconduct when pressing for resolution.

For UK buyers: Customer service is US-based (California), which can complicate communication and slow resolution times compared to UK-based competitors.

Difficult Monthly Deep Cleaning

The flexible rubber base, while comfortable for cats, makes deep cleaning challenging:

• Litter sticks to rubber aggressively
• Water cannot drain due to recessed lip around the drum floor
• Crevices collect litter that’s hard to reach
• Takes 20–30 minutes vs 10–15 minutes for Litter-Robot or Petkit

Example: One owner highlights cleaning as a notable downside. In their experience, rinsing the unit with water can be awkward because the internal shape makes it difficult to drain completely. They also report that the flexible rubber floor tends to attract and hold onto litter more than expected, which adds extra effort during cleaning.

WiFi Connectivity Issues (Less Common)

A handful of reviewers report WiFi setup difficulties or occasional disconnections. This is less frequent than with the Petkit Pura Max 2 but still noted.

The good news: The unit works perfectly fine without WiFi in standard mode – you just lose app notifications and remote control.

Clumps Get Stuck in Drum

Several owners report waste clumps occasionally sticking to the drum wall rather than falling into the waste drawer. This requires manual intervention (usually just tapping with gloved hand) to dislodge.

Frequency: Not constant, but happens often enough that multiple reviews mention it.

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

Before Leo’s Loo Too:

📸 Scoop 2–3 times per day
📸 Persistent litter smell in the flat
📸 Litter tracking moderate
📸 Anxiety about guests noticing odours

After Leo’s Loo Too:

✅ Scoop: never
✅ Smell: 95% eliminated (UV light genuinely makes a difference)
✅ Noise: imperceptible during cleaning
✅ Maintenance: 5–10 minutes per week
✅ Mental freedom: you stop thinking about the litter box entirely

The UV sterilisation system is the real differentiator here. Several owners specifically note that the waste drawer smells significantly less than standard automatic litter boxes when they empty it weekly.

Time savings: Approximately 20 minutes per day eliminated = 122 hours per year not spent scooping.

The catch: Reliability concerns mean you might spend some of those saved hours dealing with troubleshooting or customer service after 12–18 months.

Our Take:

The Leo’s Loo Too offers the quietest operation and innovative UV sterilisation. However, reliability concerns, limited UK availability, and mixed customer service experiences make it harder to recommend over proven alternatives.

Choose Leo’s Loo Too if: UV sterilisation matters more than warranty length, and you’re comfortable with potential import logistics.

Choose Petkit Pura Max 2 if: You want excellent value, UK availability, and don’t need UV tech.

Leo’s Loo Too Dimensions (Will It Fit in a UK Home?)

One of the most common questions: “How does it compare to competitors in UK bathrooms?”

Exact dimensions:

• Width: 61 cm (24 in)
• Depth (front to back): 56 cm (22 in)
• Height: 70 cm (27.6 in)
• Entrance width: 22 cm (8.5 in)
• Entrance height from floor: ~20 cm (~8 in)
• Internal drum: 53 cm (21 in) diameter

The unit needs at least 2–3cm clearance around it for radar sensors to function properly – don’t place it flush against walls.

📌 Good rule of thumb: If the Petkit Pura Max 2 fits in your space, the Leo’s Loo Too will also fit – they’re nearly identical footprints.

For small UK flats: This is one of the more compact automatic litter boxes. The round footprint actually works better in corners than rectangular designs.

Optional Accessories for the Leo’s Loo Too

The base unit works standalone, but these add-ons improve the experience:

Leo’s Loo Too Waste Drawer Liners (25-pack) – Custom-fit bags designed for the 9.5L waste drawer. Heavy-duty 2mil thick with drawstring closure. You can use standard 50–60L bin liners, but these fit perfectly and prevent bunching. (~£15 for 25 bags)

Carbon Filter Replacement (6-pack) – Absorbs odours and moisture. Replace every 2–3 months. (~£15–£20 for 6-pack)

Colour-Matched Litter Mat – Dual-layer honeycomb design captures litter from paws. Waterproof and washable. Available in matching colours (Grey, Blue, Green, Pink). (~£30)

Extended 3-Year Warranty – Casa Leo offers an extended warranty bundle. Given reliability concerns, this might be worth considering if purchasing. (~£100–£150 additional)

Step Stool (if needed) – Some owners with smaller or senior cats add a step in front. Not sold by Casa Leo but standard pet steps work fine. (~£15–£25)

You don’t need accessories initially, but the custom liners genuinely make weekly emptying cleaner and the carbon filters are essential for optimal odour control.

Total Cost of Ownership (Year 1)

Understanding the full cost helps you compare properly to alternatives:

Leo’s Loo Too:

• Unit: £550–£679 (depending on bundle and import costs)
• Waste drawer liners: ~£60/year (4 packs of 25 bags @ £15 each)
• Carbon filters: ~£40/year (3 replacement 6-packs @ £13 each)
• Potential import/shipping: £30–£80 (if not buying from UK stock)
• Total Year 1: £680–£859

Comparison:

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

The Leo’s Loo Too sits in the middle, though potential import costs can push it closer to Litter-Robot pricing without the 2-year warranty benefit.

Year 3 total (estimated):

• Leo’s Loo Too: £800–£1,000
• Petkit Pura Max 2: £900–£1,100
• Litter-Robot 4: £1,020

Hidden consideration: If the unit fails after 12–18 months and warranty disputes arise, the Leo’s Loo Too could become significantly more expensive than alternatives.

Who Should Buy the Leo’s Loo Too?

✓ Cat owners prioritising whisper-quiet operation above all else
✓ Those fascinated by UV sterilisation technology
✓ Tech enthusiasts wanting voice control integration
✓ Multi-cat homes (2–3 cats) in small UK flats
✓ Owners comfortable navigating potential import logistics
✓ People valuing compact footprint and colour choice
✓ Those with budget flexibility for potential extended warranty

Who Should Skip It

✘ UK buyers wanting easy returns and local support
✘ Anyone requiring absolute reliability beyond 18 months
✘ Those preferring eco-friendly litters (clay-only requirement)
✘ Owners of anxious cats that need larger entrances
✘ Budget-conscious buyers under £550
✘ People wanting the longest possible warranty (Litter-Robot’s 2 years better)
✘ Cat owners with very skittish cats that refuse enclosed boxes

Leo’s Loo Too FAQ (UK Buyers)

Where can I buy the Leo’s Loo Too in the UK?

The Leo’s Loo Too is available on Amazon UK, though stock fluctuates and you may encounter import listings with longer delivery times (2–4 weeks). Some UK buyers import directly from Casa Leo’s US website or US Amazon with forwarding services.

Check current UK availability:

• Amazon UK (search “Leo’s Loo Too”)
• Casa Leo official website (ships to UK but may incur customs)
• Occasional listings on eBay UK (check seller ratings carefully)

Always verify:

• UK plug included or adapter needed
• Delivery timeline (UK stock vs US import)
• Return policy (UK rights vs US returns)
• Warranty coverage (some imports void UK consumer protection)

Does the Leo’s Loo Too work without WiFi?

Yes – automatic cleaning works perfectly without WiFi. You’ll just lose app notifications, remote control, and health tracking until reconnected. The unit functions in standalone mode indefinitely.

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. Your cat can still enter and use the box during an outage, though it won’t self-clean until power is restored.

Is the UV light actually effective?

Yes – the UV-C light is EPA-approved and genuinely kills 99.9% of bacteria in the waste drawer. Multiple owners report significantly less odour when emptying compared to standard automatic litter boxes. It’s not marketing hype – UV-C sterilisation is proven technology.

Important: UV treats the waste drawer, not the litter itself. It reduces bacterial growth in collected waste, improving overall odour control.

Can I use eco-friendly litters like tofu or wood pellets?

No – Casa Leo requires clay-clumping litter only, and using alternatives voids your warranty. This is stricter than competitors:

• Petkit Pura Max 2: Works with most clumping litters (two sifter options)
• Litter-Robot 4: Works with all clumping litters

Recommended brands: Dr. Elsey’s Ultra (Casa Leo’s suggestion), World’s Best Cat Litter, Cat’s Best Original, or standard UK supermarket clay-clumping litters.

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 the drawer reaches 90% capacity.

Will anxious cats use it?

Results vary. The enclosed dome design (similar to Litter-Robot) means anxious or claustrophobic cats may refuse it. The 22cm (8.5in) entrance is smaller than open-top alternatives like the Neakasa M1 (43cm/17in opening).

Recommendation: If your cat has already refused enclosed automatic litter boxes, consider the Neakasa M1 instead. If they’re comfortable with covered manual litter boxes, the Leo’s Loo Too should be fine.

How reliable is the Leo’s Loo Too long-term?

This is the biggest concern. While many owners report trouble-free operation, there are enough reports of motor failures, sensor malfunctions, and units stopping after 12–18 months to warrant caution.

What we know:

• Positive: Many owners use it successfully for 12+ months
• Concern: Multiple reports of failures just after warranty expires
• Mixed: Customer service experiences vary dramatically

Our advice: If purchasing, strongly consider the extended 3-year warranty. Given reliability concerns, the extra coverage provides peace of mind.

What’s the warranty like?

1-year manufacturer warranty covering mechanical failures and defects. Casa Leo also offers an extended 3-year warranty bundle (additional cost).

Compared to competitors:

• Litter-Robot 4: 2 years (best in class)
• Petkit Pura Max 2: 1 year
• Leo’s Loo Too: 1 year (extended 3-year available)

Important for UK buyers: Warranty is handled by Casa Leo (US-based). This can complicate claims and slow resolution times compared to UK-based competitors.

Can kittens use the Leo’s Loo Too?

Not until they weigh at least 0.9kg (2 lbs) – roughly 3–4 months old. The weight sensors won’t reliably detect lighter cats. If you have both kittens and adults, keep a manual box available until kittens reach minimum weight.

How difficult is monthly cleaning?

More involved than competitors. The flexible rubber base holds litter stubbornly, and the recessed lip design makes it difficult to drain water after washing. Expect 20–30 minutes for a thorough deep clean vs 10–15 minutes for Litter-Robot or Petkit.

Does the entrance size matter?

Yes – the 22cm (8.5in) entrance is smaller than most competitors. Some cats (particularly larger breeds or those who don’t like turning around in tight spaces) may struggle or refuse to use it properly.

One UK reviewer noted: “Despite having the Leo’s Loo for two years, she never once learned to turn around because of the small opening. Comparatively, the very first time she used the Litter-Robot, she turned around and used it like normal.”

If your cat is nervous or large (5kg+), consider models with larger entrances.

Is it worth the money compared to cheaper alternatives?

Possibly – if UV sterilisation and 30dB quiet operation are priorities. However, reliability concerns and potential import costs make value proposition less clear than UK-available alternatives like the Petkit Pura Max 2 (£479–£679) or even the Litter-Robot 4 (£749) with its 2-year warranty.

Value depends on:

• Whether you can buy from UK stock (avoiding import costs)
• How much you value UV tech over proven reliability
• Your risk tolerance for potential 12-month+ failures
• Whether you purchase extended warranty

Final Verdict

The Leo’s Loo Too delivers where it promises: genuinely whisper-quiet operation, innovative UV-C sterilisation, and excellent app integration with voice control. At 30dB, it’s the quietest automatic litter box we’ve researched, and the UV light genuinely improves odour control in the waste drawer.

However, the combination of limited UK availability, reliability concerns after 12–18 months, and inconsistent customer service experiences makes it harder to recommend over proven UK alternatives. The Petkit Pura Max 2 offers similar features at £479 (£100–£200 cheaper), and the Litter-Robot 4 provides superior warranty and customer support for £70–£200 more.

If you choose the Leo’s Loo Too: Buy from UK stock when possible, strongly consider the extended 3-year warranty, and keep your receipt/documentation organised in case warranty claims are needed.

If you want guaranteed reliability: Spend extra on the Litter-Robot 4’s 2-year warranty and UK support network.

If you want better UK value: The Petkit Pura Max 2 is £100–£200 cheaper with excellent UK availability and nearly identical features (minus UV light).

For our situation, the UV sterilisation technology is genuinely impressive, but the reliability concerns and import logistics make it a riskier choice than competitors with stronger UK presence. The Leo’s Loo Too is an innovative product let down by execution and support infrastructure for UK buyers.

⭐⭐⭐⭐ – Innovative UV tech and whisper-quiet, but reliability and UK logistics concerns prevent a higher rating
