Why it ranks here. The Litter-Robot 4 is the box every other is measured against: near silent, sealed against smell, a support team owners praise, and millions sold without a safety incident. It ranks first for that. It costs $650 to $800, its liners and hoppers add up, and it is the wrong box for a cat that pees standing.
'Bought a LR4 last year'↗, says one owner: 'my 15 years of scooping ended'↗. An owner of five Litter-Robots says 'The LR4 is a marked upgrade, especially the noise, it's practically silent'↗, and that they 'are engineered for safety to within a nanometer'↗. Another has 'excellent smell control'↗. Owners empty the drawer weekly with two cats, and one owner calls it the best cat investment ever. Then the standing pee: 'if you have a weird cat that pees standing up (not crouching) THIS IS NOT THE LITTER BOX FOR YOU!'↗, says a three-year owner, since 'you can NOT clean the base'↗ with its 'loose wires'↗. Another with two standing cats took his apart, 'like 75 screws total'↗. A three-cat home changes the bag daily and fights 'dirty sensors that arent easy to clean'↗; others fixed sensors by switching to Arm and Hammer Slide. Liners run '$70 on a new liner every 3 years'↗.
What owners like
“Litter Robot is pricey but they are engineered for safety to within a nanometer. They are obnoxiously safe, the main complaints about them involve false positives of the safety features (which can interrupt them cycling/emptying). I've got five 4 LR3s and 1 LR4, they're all great. The LR4 is a marked upgrade, especially the noise, it's practically silent.” — Reddit comment · u/Zoethor2 · r/CatAdvice · 2025-08-23

I know nothing of the Pura Max 2, but I am very happy with my Litter Robot 4. It is very quiet & has excellent smell control. I've only had it for about 2 months, so I can't speak to long-term reliability, but it has worked perfectly so far.

If price to performance matters a lot, I would not automatically jump to the €900 Litter Robot unless budget is not a concern. The Litter Robot 4 is excellent in terms of build quality, long term reliability, and customer support. It feels very polished and is typically quiet. But you are definitely paying a premium for the brand and support structure.

First off i want to start by saying this is MY opinion i have made about this after 3 years of use. Okay so if you have a weird cat that pees standing up (not crouching) THIS IS NOT THE LITTER BOX FOR YOU! litter robot didn’t think about the weird cats and the amount of pee that gets through all the little openings is INSANE. If y’all didn’t know you can NOT clean the base like you do the other parts. there is loose wires that can’t get wet so cleaning the base is the devil in disguise. My weight doesn’t even drop down anymore and of course the warranty is out. I shouldn’t have to spend $70 on a new liner every 3 years. that’s insane.

Agree 100%, I hate this thing so much now! Only had it for a year and a half. Cats that stand to pee aren't the norm but they are pretty common. Two of my four stand when they pee. Whisker knows about the design flaws but they wont fix it. I had to completely disassembled the entire unit, globe and base. It's like 75 screws total. Had to completely remove the wire harnes, circuit boards, and motor so i could hose spray and bucket wash the base. There is dried urine everywhere in every part.

Only 70$ for replacement parts every 3 years is pretty good imo. They aren't built to last forever

I have 2 LR4s and changed them in 5 minutes yesterday before work. Both LR are at least 2-3 years old and both have litter hoppers… I feel like I save on litter too since Im only changing whats in the bag and refilling the hopper as needed... I have no regrets about my LR4s.

My wife and I have the litter robot 4. We have 3 cats and we have to change the bag everyday or if we're lucky every other day. I try to clean the sensors but its really hard despite sticking my head into the spinning dome of piss and shit... So what's the point of spending 700-800 dollars on a machine to solve your problem when you just have a new one? The new problem being dirty sensors that arent easy to clean.
-
Could be the type of litter you're using. I use Arm & Hammer platinum slide multicat and don't have an issue with the sensors... With my two cats we change the bag about once a week. I buy off brand bags from Amazon that work great and are a lot cheaper
-
We have a new LR5, but decided not to buy the ramp. Compared with the LR3 ramp, this one is a step backward... Like several other LR5 features, I can see the design idea behind this ramp—it prioritizes appearance over everyday usability.

I never knew a cat product reviewing video could be such a cinematic masterpiece. This is like a BBC show. 🙀

We love our Litter Robot 4. We bought a “refurbished” machine and the $100 saved paid for the additional 2 year warranty... Best “cat investment” ever, thankfully we are in a financial position to be able to fit it in the long term budget
-
I think the fact that whisker was willing to help solve issues with there product is a MAJOR selling point for me. Knowing I’ll have good support from them is an incredible sense of relief. Plus it really shows they stand by their product.

Bought a LR4 last year, the lead time was about 6 weeks. It delivered within the lead time window and my 15 years of scooping ended. Errors here and there, but nothing that has put the cats at risk. My cats took to the LR4 in no time, Whisker really nailed it with this device... A must for multi cat owners.

Hi, u/NectarineBrilliant65! Thank you for reaching out to us. We're sorry to hear that the globe liner weight is no longer dropping and that there has been trouble with the waste drawer. We'd like to assist. Can you send us a chat that includes your Litter-Robot 4's serial number so we can look into this further for you?
