"I have three cats and this has completely changed my life. I scooped litter every single day for years. Now I empty a drawer once a week and that's it. Worth every penny."

"The health monitoring caught my cat's kidney disease early. His visit frequency spiked and the app flagged it. The vet confirmed an issue. I credit this machine with probably adding years to his life."

"My husband refused to get it at $700. One month in he admitted it was the best purchase we've made for our cats. No smell, no scooping, no mess."

"I've had mine for four years and it's never missed a cleaning. The build quality is genuinely excellent for a product with moving parts that runs multiple times a day."

My cat refused to use it for two weeks…
My cat refused to use it for two weeks — she'd sniff it and walk away. I had to put treats inside every day and remove her old box entirely before she finally committed. Worth it now, but the transition was stressful.
Source: Amazon reviewerExpensive and the consumables add up…
The drawer liners and filters aren't optional and they cost real money. After a year the total cost is way more than the $700 purchase price. I love the unit but I wasn't prepared for the ongoing expense.
Source: RedditHad a motor issue after 14 months…
The globe stopped rotating after 14 months — just past the warranty. Litter-Robot support was helpful and sold me a replacement motor at cost, but having to repair a $700 appliance in year two wasn't what I expected.
Source: Amazon reviewerTakes up a lot of space…
It's much larger than I expected. With the cover on it's almost 30 inches tall and nearly 2 feet wide. In my apartment bathroom there was no way to fit it — I had to put it in the bedroom which is less than ideal.
Source: Amazon reviewerThe Litter-Robot 4 is the best automatic litter box you can buy — the automation is genuinely reliable, the odor control is exceptional, and the app health-monitoring is a real bonus for attentive cat owners. The $699 CAD price is hard to swallow, and the unit only makes sense if you have cats that will accept an enclosed globe and you're committed to clumping litter. For multi-cat households that hate scooping, there is no better option at any price.
