If you are fed up with scooping, an automatic litter tray can take one regular job off your list. It will not make the tray maintenance-free, though, and a £200-plus machine is a frustrating purchase if your cat refuses to use it.
For most homes, I would start with the Whisker Litter-Robot 4 Beginner Bundle (Ad) if you want the established premium option and have the space. If your cat prefers an open tray, look at the Neakasa M1 Plus (Ad) instead. The other picks below suit people who want a simpler machine, camera features or a rake-and-crystal system.
One useful distinction: “AI litter box” is often used loosely. Some machines simply sift litter automatically; others add an app, camera or usage tracking. Those extras can be handy, but they do not diagnose health problems or guarantee that a cat will accept a moving tray.
I have not physically tested these machines. This is a researched shortlist based on current Amazon UK listings and manufacturer information. I have linked the exact models, and left out fixed prices because they can change between visits. Check the product page for today’s price, seller, bundle and delivery details.
At a glance: which automatic litter tray fits your home?
| Model | Best for | Litter / style | Think twice if… |
|---|---|---|---|
| Whisker Litter-Robot 4 Beginner Bundle (Ad) | A premium all-round machine with app monitoring | Rotating globe; clumping litter | You have little floor space or do not want a large upfront cost |
| Neakasa M1 Plus (Ad) | Cats that prefer an open-top tray; larger cats | Open-top sifting tray; clumping litter | You need a compact or fully enclosed unit |
| CATLINK Young Version (Ad) | A simpler automatic globe without app setup | Rotating globe; check litter compatibility | You want app controls or detailed usage tracking |
| PETKIT PUROBOT MAX PRO 2 (Ad) | Camera and app-based monitoring | Enclosed automatic tray; check litter and app terms | You would not use the camera or want to avoid connected features |
| PetSafe ScoopFree, Second Generation (Ad) | A rake-style tray rather than a rotating drum | Covered tray; ScoopFree crystal litter only | You want to use your usual clumping litter |
1. Whisker Litter-Robot 4 Beginner Bundle: best premium all-rounder
Best for: someone who wants a well-established, app-connected machine and is comfortable spending more for convenience.
The Litter-Robot 4 is the pick I would compare first if the main goal is to cut down on daily scooping without switching to a crystal-litter system. It sifts clumping litter after use, then stores waste in a drawer. The Whisker app adds usage and weight information, which can help you notice changes in routine. The Amazon link here is for the Beginner Bundle, not the bare machine: it includes the tray plus a mat, fence, liners and odour-control refills.
The trade-off is size and cost. Whisker lists the machine at about 75 cm high, with a footprint around 56 by 69 cm, before allowing space to get to the drawer. Measure the actual spot, including room to open and clean it. The bundle is at the premium end, and you still need to empty the drawer and clean the globe. It is also not an instant fix for a nervous cat.
Whisker says cats should weigh at least 1.4 kg to use automatic mode. Follow the current instructions for your cat’s age and weight, and leave a familiar tray available while they get used to the new one.
2. Neakasa M1 Plus: best open-top automatic litter tray
Best for: cats that dislike enclosed trays, and owners who want more room for a larger cat.
The M1 Plus has an open top, so a cat does not have to step into a covered globe. That is a meaningful difference, not just a styling choice. Its open design may be easier for some cats to approach, and Neakasa describes it as a roomy option for larger breeds. It uses a sifting cycle to separate clumps into a waste drawer, with app controls and activity information.
It still takes up a lot of floor space, and the open top means litter can be kicked out more easily than from a covered unit. Neakasa recommends fast-clumping litter; wood pellets and non-clumping types are not a safe assumption. Check the exact instructions for the litter you already use before buying. The M1 Plus pack includes accessories that vary from the Lite version, so make sure the Amazon listing is for the Plus model if those extras matter to you.
3. CATLINK Young Version: a simpler automatic globe
Best for: buyers who want an automatic rotating tray but do not need app control.
This exact Amazon listing is the CATLINK Young Version. It has a 57-litre drum and a 13-litre waste drawer, with sensors that pause the cleaning cycle when the unit detects a cat. Unlike some CATLINK models, this version is presented as a plug-in machine without Wi-Fi or app features. That keeps setup simpler, but you will not get app alerts or cat-by-cat usage records.
It is still a large enclosed box, and its Amazon rating sample is much smaller than the long-established premium models in this guide. CATLINK says automatic use is for cats from about 1.6 kg and advises manual mode for smaller kittens. Its support information also rules out several non-clumping and pellet-style litters. Check the manufacturer’s current compatibility list, measure the entrance and do not assume that every litter labelled “natural” will work.
4. PETKIT PUROBOT MAX PRO 2: best if you will use the camera features
Best for: owners who genuinely want camera-based activity features and app monitoring.
This is the most feature-heavy option here. The exact Amazon model is the PUROBOT MAX PRO 2 with camera, not the similarly named PuraMax 2. It connects to the PETKIT app and is sold around camera-based pet identification and monitoring. That could be useful in a multi-cat home if you want to see which cat is using the tray. If you only want waste sifted automatically, most of those extras may not earn their keep.
Before ordering, check the current app terms, what is available without a subscription, how recordings are stored, and whether the size suits your cat. The camera and app provide observations, not a veterinary diagnosis. If you notice a change in urination, toileting or behaviour, contact your vet rather than relying on a litter-box notification.
5. PetSafe ScoopFree Second Generation: best for a rake-and-tray system
Best for: someone who prefers a familiar tray shape and is happy to use crystal litter.
This works differently from the rotating machines above. A rake moves waste into a covered compartment, while the crystal litter absorbs moisture. It may feel like a less dramatic change from a standard covered tray, and the rake is easy to understand. The Amazon listing is the covered Second Generation version, which has a simple counter for rake cycles.
The important catch is the ongoing system cost. PetSafe’s support guidance says to use ScoopFree crystal litter with this model. You are not just buying the tray; you are choosing replacement crystal litter trays or the compatible reusable setup. Check the refill price and replacement frequency for your household before deciding. If you want to keep your usual clumping litter, pick one of the sifting machines instead.
Before you buy an automatic litter box
Will your cat use a covered or moving tray?
There is no guarantee. Keep the old litter tray in place while your cat investigates the new one. Let them approach it in their own time, and follow the manufacturer’s transition advice. Do not switch on automatic cleaning for a kitten or cat that falls below the model’s stated weight or age limit.
What litter does it accept?
This can decide the purchase. The rotating and open sifting machines generally depend on litter forming firm clumps that fit through their screens. ScoopFree Second Generation is the exception here: PetSafe says to use its crystal litter. If changing litter would upset your cat or add a regular cost you do not want, choose a machine that suits the litter you already buy.
How much room will it really need?
Do not measure only the machine. Leave room to enter, remove the waste drawer, lift parts for cleaning and reach a socket. Check the height and entry opening too, especially for an older or less mobile cat. The Litter-Robot 4 and Neakasa M1 Plus are both larger than their product photos make them look.
Does it remove all the work?
No. You still empty waste, top up litter and wash the unit. Bags, filters, odour-control refills and crystal trays can add to the cost. Before ordering, look at the price and availability of the parts you expect to replace, not just the machine itself.
So, which one would I choose?
If I wanted one premium machine for a home that has the space, I would choose the Litter-Robot 4 bundle. It is a clear product, the Amazon listing is for the full bundle, and it does not force you into a crystal litter system. I would choose the Neakasa M1 Plus instead for a cat that is more likely to accept an open tray. For a camera or an app, the PETKIT is the specialist pick, but I would not pay extra for those features unless I expected to use them.
If none of these feels like a clear fit, keep the normal tray. A machine that your cat avoids is not a time-saver. Compare today’s price, exact model and running costs before you decide.
Sources and how we chose
Product names and model matches were checked against the linked Amazon UK listings. For specifications and limitations, see the manufacturers’ Litter-Robot 4 guide, Neakasa M1 comparison, CATLINK Young product page, PETKIT PUROBOT MAX PRO 2 manual and PetSafe ScoopFree Second Generation guidance. We compared the use case, litter requirements, space and ongoing upkeep; we have not tested these machines in a home.
