Litter-Robot 5 is now the best overall automatic litter box for most households. It is the newer generation above Litter-Robot 4, with more room for large and multi-cat homes and newer waste tracking features.
But it is not the right box for every cat. Neakasa M1 Plus is easier for cats that dislike enclosed drums, PETKIT Purobot Ultra is the strongest choice for camera-based monitoring and low-touch waste handling, and PuraMax 2 remains the better value pick.

Litter-Robot 5 is the new first choice
Litter-Robot 4 was the safest default for a long time, but the newer Litter-Robot 5 now makes more sense for most buyers starting from scratch. It gives you the current Whisker platform without making you pay for the 5 Pro's camera system.
Keep Litter-Robot 4 on your shortlist when it is meaningfully cheaper. It is still a mature, proven machine with a large installed base and strong accessory support.
New Models You Should Know About
Litter-Robot 5
The current best Litter-Robot for most buyers. It is the model we would choose over LR4 when the price difference is reasonable.
Litter-Robot 5 Pro
The camera-equipped version for owners who specifically want live viewing and camera-based cat identification. Most buyers can save money with the standard LR5.
Litter-Robot EVO
A smaller, lower-priced Whisker model for one or two cats and tighter spaces. It is a better fit than LR5 when you do not need maximum capacity.
Neakasa M9
The upcoming next-generation Neakasa model adds a lower entry, larger open cabin and upgraded odor-control design. It is the model to watch if you like Neakasa but want newer hardware than M1 Plus.

A newer PETKIT flagship with AI camera monitoring, automatic waste packing and a large waste bin. It is a stronger low-touch premium alternative than Furbulous for most shoppers.
CATLINK Scoop Robot Pro
A newer camera-equipped model that is interesting, but it does not yet displace the stronger category leaders in this ranking.
PetSafe ScoopFree SmartSpin
A sensible midrange alternative from a familiar pet-care brand, especially when you want to stay below flagship pricing.

Our Top Picks in Detail
Litter-Robot 5
Litter-Robot 5 is the best choice for most buyers starting fresh in 2026. It keeps the strengths that made Litter-Robot 4 easy to recommend, then adds newer capacity and tracking features without forcing you into the more expensive 5 Pro camera model.
Who should buy it: multi-cat homes, owners of larger cats, and buyers who want the current Whisker platform.
Who should skip it: cats that strongly prefer an open box, or buyers who can get Litter-Robot 4 at a meaningfully lower price.
Compare Litter-Robot 5 vs 4 before deciding whether the upgrade matters in your home.
Neakasa M1 Plus
M1 Plus is the easiest recommendation when cat acceptance matters more than enclosure-based odor control. The open top feels more like a traditional litter box and gives larger cats more visible space.
Before buying, compare M1 Plus with the newer M9 and lower-cost M1 Lite Plus in our Neakasa Automatic Litter Boxes Compared.
Who should buy it: large cats, cautious cats and cats that dislike entering enclosed drums.
Who should skip it: homes where maximum odor containment is the first priority.
🛒 Check AmazonPETKIT Purobot Ultra
Purobot Ultra is the biggest change to this shortlist. It adds an AI camera, multi-cat recognition, automatic waste packing and automatic bag replacement, making it much more ambitious than PuraMax 2.
Who should buy it: multi-cat homes that want deeper usage tracking and owners who want less contact with the waste routine.
Who should skip it: buyers who do not want a camera, do not need the extra monitoring, or want a smaller machine.
🛒 Check AmazonPETKIT PuraMax 2
PuraMax 2 remains the more sensible PETKIT choice when you want automatic cleaning, app control and odor features without paying for Purobot Ultra's camera and waste-packing hardware.
Who should buy it: value-focused buyers who still want a full smart litter-box experience.
Who should skip it: very large cats or buyers who specifically want camera-based individual tracking.
🛒 Check AmazonPetSnowy SNOW+
SNOW+ is the specialist pick for households where smell is the reason they want to automate. Its enclosed design and automatic packing make the ownership routine feel different from a standard drawer-based machine.
Who should buy it: odor-sensitive homes and owners who want sealed waste handling.
Who should skip it: cats that dislike enclosed toilets or buyers with very limited floor space.
🛒 Check AmazonPetSafe ScoopFree SmartSpin
SmartSpin is not as feature-heavy as the premium leaders, but it is a cleaner recommendation than many lesser-known Amazon-only machines. PetSafe is a familiar pet-care brand and the current SmartSpin listing sits in a useful middle price tier.
Who should buy it: buyers who want a recognizable brand and automatic cleaning without going straight to flagship pricing.
Who should skip it: owners who want the deepest app tracking, camera monitoring or open-top design.
🛒 Check AmazonWhat Happened to Litter-Robot 4 and Furbulous?
Litter-Robot 4 is still worth buying
It is no longer our first choice simply because Litter-Robot 5 is now the current-generation model for most Whisker buyers. LR4 remains a strong purchase when it is discounted enough to make the savings meaningful.
🛒 Check AmazonFurbulous moves to “also consider”
Its self-packing idea is still useful, but PETKIT Purobot Ultra now gives buyers a more complete premium low-touch package with camera monitoring and a larger established ecosystem.
If you have one or two cats and limited floor space, EVO may make more sense than a larger LR5 even though it does not rank as the best all-around box.
