Some of the products we link to are partners who may pay us when you buy through them. This doesn't change which ones we recommend. How this works.
No. A Litter-Robot works as a self-cleaning litter box with no subscription of any kind, and Whisker says outright that the app itself "is not required for Litter-Robot to function," it'll keep cycling even without WiFi. What costs money is Whisker+, a $7.99/month (or $79.90/year) membership that unlocks longer video history and deeper behavior analytics on the Litter-Robot 4, 5, 5 Pro, and EVO. Separately, Whisker also sells a cat litter delivery subscription, an autoship service for buying litter and waste-drawer liners on a schedule. That one has nothing to do with data or cameras, it's just recurring shipping, and it's entirely optional too. A lot of the confusion about "does Litter-Robot need a subscription" comes from these two unrelated things sharing the word "subscription."
What’s Always Free, Permanently
The core function, self-cleaning after each use, works with no account, no app, and no WiFi connection. Whisker’s own FAQ states it plainly: the box keeps cycling as a standalone appliance even if you never connect it.
Connect it to the free Whisker app and, per Whisker’s own feature list for the Litter-Robot 4, you get real-time alerts when a cleaning cycle starts, pauses, or the waste drawer needs emptying; litter level and waste drawer status at a glance; general usage trend tracking; remote controls for cycle delay, control panel lock, night light, and sleep mode scheduling; and support for managing multiple units in one app. None of that requires Whisker+. You also get SmartScale weight tracking and cat identification on compatible models at no charge, that’s part of the base hardware and app, not a paid add-on.
- What’s free: cycling, remote control, alerts, waste/litter status, basic usage trends, weight tracking, multi-cat identification.
- What isn’t: extended video history and the deeper behavior-pattern analysis covered below.
Whisker+: The Subscription That Unlocks Cameras and Long-Term History
Whisker+ costs $7.99/month, or $79.90 billed annually (about $6.66/month, marketed as “2 free months” versus paying monthly), and comes with a 30-day free trial. It’s compatible with the Litter-Robot 4, Litter-Robot 5, Litter-Robot 5 Pro, and Litter-Robot EVO. It is not available at all for the older, still-sold Litter-Robot 3 Connect, that model simply isn’t part of the Whisker+ program, so there’s no upsell to weigh on it either way.
Without Whisker+

- Behavior pattern trackingNot included
- Live video streamingNot included
Whisker+
- Video/event history30 days
- Behavior pattern trackingBathroom habits, frequency, timing, up to 2 years of activity history
- Live video streamingUnlimited
- Who should NOT pay for Whisker+: anyone who just wants to know the box is cycling and the drawer isn’t full. That’s free, permanently, with no time limit on the alerts or status features themselves.
- Who it’s right for: multi-cat households trying to catch which cat is using the box unusually often (an early symptom of illness in cats), or anyone who’s ever wanted to check what actually happened overnight and found only 2 days of history available for free.
The Other “Subscription”: Litter and Supply Delivery
Separately from Whisker+, Whisker sells cat litter, waste-drawer liners, and OdorTrap refills through an autoship subscription: choose a quantity and a delivery frequency (monthly, every two months, or quarterly) and it ships and charges automatically on that schedule. This is a standard recurring-commerce subscription, not a data or software feature, and it has no connection to Whisker+ at all; you can run a Litter-Robot on either, both, or neither.
Per Whisker’s own subscription terms, there are no membership fees, adjustment fees, or cancellation fees attached to it, and you can pause a delivery, skip the next shipment, or cancel outright by logging into your account, provided you do it at least five business days before the next scheduled shipment. It’s worth comparing the autoship price against buying litter locally or through a general retailer before assuming the convenience discount is automatically the better deal, particularly for households that don’t use Litter-Robot’s own branded litter exclusively.
- Who should NOT bother with litter autoship: anyone whose local pet store or regular retailer already beats the delivered price, or who uses a litter brand other than what Whisker sells.
- Who it’s right for: anyone who wants to stop thinking about running out of litter or liners and is fine with Whisker’s own litter as the default.
Litter-Robot 4
Self-cleaning litter box, WiFi app included at no charge; camera history and behavior analytics only if you add Whisker+. ~$699 official price.
Who Should NOT Buy a Litter-Robot At All Over the Subscription Question
If the appeal of a self-cleaning litter box is specifically the idea of remote camera monitoring and health-trend alerts, and you’re not willing to pay $7.99/month for it, a Litter-Robot won’t deliver that experience for free, the 2-day history and lack of behavior-pattern tracking on the free tier is a real limitation, not just a teaser. Anyone in that position should budget for Whisker+ from the start rather than assume the free app tier will feel equivalent. Conversely, anyone who wants a self-cleaning box purely for the physical convenience of not scooping, with no interest in data or video at all, is fully served by the free tier and should ignore the Whisker+ upsell entirely.
This is the same shape as other hardware-plus-data-subscription products this site has covered: the box itself works, and the recurring fee is for a layer of insight on top, not the appliance’s core job. See our myQ garage door guide and our Garmin Connect+ guide for the same pattern in a different device category.
FAQ
Does the Litter-Robot app cost money? No. The Whisker app itself is free, and Whisker’s own FAQ states the app isn’t required at all for the litter box to function, it will keep self-cleaning even without a WiFi connection. Whisker+ is an optional paid tier inside the same app.
What does Whisker+ actually unlock? Extended video and event history (30 days instead of 2), unlimited live video streaming, deeper behavior-pattern tracking (frequency, timing, and changes in bathroom habits), and up to 2 years of stored activity history. It costs $7.99/month or $79.90/year, with a 30-day free trial.
Is the litter delivery subscription the same thing as Whisker+? No, they’re unrelated. Whisker+ is a data and camera subscription inside the app. The litter/supply autoship is a standard recurring-shipping subscription for buying litter, liners, and filters on a schedule. You can use either, both, or neither.
Does the Litter-Robot 3 Connect support Whisker+? No. Whisker+ is only offered for the Litter-Robot 4, 5, 5 Pro, and EVO. The Litter-Robot 3 Connect, still sold as a lower-priced option, isn’t part of the Whisker+ program at all.
Can I cancel the litter autoship subscription anytime? Yes. According to Whisker’s own subscription terms, there are no cancellation or adjustment fees. You can pause, skip a shipment, or cancel from your account, as long as you do it at least five business days before the next scheduled charge.
Bottom Line
- Just want a self-cleaning litter box with basic remote monitoring: skip every Whisker subscription. Cycling, alerts, waste status, and weight tracking are free, permanently, and the box works even offline.
- Want camera playback or to track behavior changes over time: Whisker+ at $7.99/month (or $79.90/year) is the only way to get more than 2 days of history; there’s no cheaper tier that includes it.
- Own a Litter-Robot 3 Connect: Whisker+ isn’t offered for your model either way, so this isn’t a decision you need to make.
- Considering the litter autoship: it’s a separate, unrelated subscription with no cancellation fees; compare its price against your usual litter source before assuming it’s the better deal.
