Stop Scooping and Start Knowing: A Smart Litter Box That Tracks Each Cat

By Editorial Team | April 2026

Intro

If you live with multiple cats, the question isn’t whether you want a self‑cleaning box — it’s whether you want one that tells you which cat used it and flags health changes. Our pick is the PUROBOT Max Pro 2 because it stops the daily scooping and turns toileting into usable, per‑cat health data.

Our pick: PUROBOT Max Pro 2

PUROBOT Max Pro 2 — £599.99

This unit makes the litter box routine nearly invisible: it recognises individual cats, logs urine and stool events, seals waste in an 8L drawer and keeps odours down so you don’t have to empty or sniff the tray every day. It’s our top choice for multi‑cat homes that want actionable health signals, not just automated scooping. (Score: 8.2)

Why it works:

• Facial recognition + 1080p AI camera (210° wide + IR) ties each toileting event to the right cat so you stop guessing who’s straining or going less often.
• Weight sensors and event logs produce trend data for urine and stool frequency — actual signs you can show your vet.
• A 43% larger entry and 25cm low step‑in make the Max Pro 2 genuinely usable for big, nervous or older cats; fewer refused visits equals more reliable data.

The honest trade‑off: It costs significantly more than basic automatic boxes and the camera/app will bother owners who refuse any connected devices.

If you want this level of monitoring and sealed, low‑odour disposal, grab the PUROBOT Max Pro 2 here: PUROBOT Max Pro 2.

Best upgrade: Litter‑Robot 4

Litter‑Robot 4 — ~£739

Paying more gets you a widely proven platform: larger waste drawer options, a very mature app/ecosystem, and a long service history with accessories and parts easy to find. It doesn’t have facial recognition, but it handles multi‑cat litter volumes reliably and has strong odour control on par with premium units.

Worth it if: you want the most established, well‑supported automatic box and prefer hardware longevity over per‑cat health imaging.

Best budget pick: PetSafe ScoopFree Ultra

PetSafe ScoopFree Ultra — ~£119.99

This is a raking, disposable‑tray system that removes daily scooping without a big upfront spend. It keeps odours down using crystal litter and is easy to set up — the trade‑offs are recurring cost for disposable trays and far less intelligence: no per‑cat data, no weight sensing, no camera.

Worth it if: you want a cheap, reliable scooping replacement and don’t care about health tracking.

How we chose

We prioritised features that actually matter to multi‑cat owners: accurate per‑cat attribution, meaningful toileting metrics (frequency, weight), odour containment, waste capacity and real‑world usability for larger or older cats. We cross‑checked manufacturer claims, current UK prices and recent reviewer notes about app reliability and face‑recognition performance.

Frequently asked questions

Will the camera invade my privacy or my cat’s? The camera is used for cat identification and event images; images and alerts are handled through the app. If you’re uncomfortable with a connected camera, this isn’t the unit for you — the Max Pro 2 is a smart device and relies on that feed for its core features.

Is £599.99 worth it compared with cheaper boxes? If you have two or more cats and want per‑cat toileting data that can spot early urinary or stool issues, the Max Pro 2’s combination of camera, weight sensors and sealed 8L bin justifies the premium. If you only want automatic scooping, lower‑cost options (PetSafe ScoopFree) deliver the main benefit for a fraction of the price.

How often will I need to empty or replace parts? Manufacturer figures say the 8L sealed waste drawer can last roughly 17 days per cat; deodoriser capsules are replaceable (N50/N60) and the unit has a high‑efficiency fan. Expect predictable consumables: deodoriser capsules, occasional waste‑bag replacements, and normal app/firmware updates.

Verdict

If you live with multiple cats and want to stop guessing who’s using the box — while getting early signs of urinary or stool problems — PUROBOT Max Pro 2 earns that use. If you only need a cheaper scooping replacement and object to cameras, choose the ScoopFree style systems instead.
