We haven’t tested the Litter-Robot 5 ourselves. This review draws on WIRED, whose tester Kat Merck used one with two cats for several months, plus Whisker’s specs and the Amazon listing.
The Litter-Robot 5 is Whisker’s newest globe. It keeps the Litter-Robot 4’s large entry, raises the limits to five cats from 3 to 30 lb, and adds WasteID, which tells urine visits from stool visits. Whisker sells the robot for $799. On Amazon it comes only as the Protection & Insights Bundle, which first appeared on October 16, 2026, and we couldn’t capture that bundle’s price. Check the price and compare it with Whisker’s.
Who it’s for (and who should skip it)
It’s for large-cat and multi-cat households. A 25 lb-plus Maine Coon, or a home with five cats, is outside what the Litter-Robot 4 is rated for and inside what the LR5 covers. It also suits owners who want health data on top of hands-off scooping and don’t mind a subscription to get it.
Skip it if you have one to three average-size cats. The LR4 does the same core job for about $100 less at Whisker, and the Litter-Robot EVO costs $200 less if your cats stay under 19 lb. We set all three side by side in Litter-Robot 5 vs Litter-Robot 4 vs EVO. Skip it as well if you don’t want to pay yearly for features the box advertises.
How it cleans, and how safe it is
The LR5 is a rotating globe that sifts clumps into a sealed drawer, like the LR4. Whisker’s SafeCat system with OmniSense uses multiple lasers plus weight sensors and anti-obstruction detection to spot a cat and stop the cycle.
Does the entry stay open through a full cycle? That’s not confirmed. Neither Whisker’s page nor a named review in our sources says so for the LR5, and it isn’t one of WIRED’s picks, which are the boxes WIRED confirms stay open. We’d expect it to behave like the LR4, but we won’t state it as fact.
The minimum is 3 lb for automatic mode. Under that, Whisker says to keep it powered off and cycle it by hand. The cat safety checker compares your cat’s weight, age and length with the LR5’s limits. For the wider picture, read are self-cleaning litter boxes safe?.
Living with it
WasteID and the app
WasteID times cycles differently for urine and stool and logs which is which. In WIRED’s testing, WasteID and weight-based cat identification worked only intermittently for the first four months, then improved markedly after firmware updates. Both need Whisker+ (about $80 a year, per WIRED). Without it, you still get a capable cleaning robot.
WIRED found the touchscreen finicky and preferred the LR4’s physical buttons. If you want cameras too, the LR5 Pro costs $999 at Whisker and has dual AI cameras, and WIRED says it needs Whisker+ for reliable AI.
Litter, emptying and odor
Whisker recommends clumping clay. The drawer is sealed and uses a carbon filter. In WIRED’s testing it held about 10 days of waste from two cats. See best litter for self-cleaning litter boxes for specific picks.
Size
The LR5 uses the same 22 × 27 in footprint as the LR4 but stands 29.9 in tall and weighs 28.7 lb. Inside, there’s 17.5 in of headroom, about an inch more than the LR4.
Running costs
The LR5 takes the same liners, carbon filters and OdorTrap packs as the LR4. Our cost model uses Whisker’s prices: liners at $25 for 25 (about four per cat per month, our assumption from Whisker’s 8-day emptying figure) and carbon filters at $30 for 6 (one per cat per month). Litter is Dr. Elsey’s Ultra at $22.99 for 40 lb from Chewy, at 10 lb per cat per month.
That’s about $14.75 a month for one cat. Over five years, with the robot at $799, we estimate about $1,684 for one cat and about $2,569 for two. Whisker+ is extra: about $80 a year, or roughly $400 over five years, minus the six months included in the Amazon bundle. Change any of these numbers in the cost calculator.
What you’ll need beyond the box
- Litter: Dr. Elsey’s Ultra unscented, 40 lb.
- Liners: Litter-Robot drawer liners, 25-pack.
- Cleaning and odor: Whisker’s cleaning supply kit (about $85 in a listing snapshot) includes wipes, 25 liners, spray and six OdorTrap refills. The carbon-filter packs on Amazon are listed for the LR4, so check Whisker’s site for the right LR5 pack before you buy in bulk.
- Ramp and mat: WIRED recommends adding a ramp (about $75) and a mat (about $50). A Gorilla Grip 40 × 28 in mat is a cheaper way to cover the floor in front of the entry.
On warranty, the robot alone comes with one year of WhiskerCare. The Amazon bundle extends that to three years. Whisker’s holiday banner on November 12, 2026 advertised $150 off select Litter-Robot bundles, so compare our Black Friday deals roundup before you pay full price.
Bottom line
The Litter-Robot 5 has the highest cat count of any box we cover and the highest weight limit of any hooded one, on top of Whisker’s laser-and-weight safety system. It’s the right call for very large cats and five-cat homes. WasteID is a genuinely new health tool, but it needs a subscription, and it took months of firmware updates to settle down in WIRED’s testing.
If your cats are under 25 lb and you have four or fewer, the LR4 is the better value. If you’re unsure, see our best self-cleaning litter box for large cats and multi-cat guides, or check the Litter-Robot 5 bundle price.
