Whisker Litter-Robot 4
What the marketing price hides
The Litter-Robot 4 is marketed at $699, which is 62% of what you'll actually spend over three years. Honestly? Not much. There's no subscription, and the only recurring cost is $12/mo in non-proprietary consumables (any clumping litter + optional liners/filters) you can buy anywhere.
One more thing the listing won't emphasize: the core function works without the cloud. If the app is discontinued or your Wi-Fi drops, the device keeps doing its job. See the full Litter-Robot 4 verdict for the score breakdown, or compare it inside its category on the device database.
