Litter-Robot 4
by Whisker · June 2022
The Litter-Robot 4 is an automatic self-cleaning litter box from Whisker that uses a patented rotating globe to sift clumps into a sealed drawer below. The OmniSense detection system uses weight sensors, a laser curtain, and capacitive sensing to detect cats and track their weight over time. The Whisker app provides usage analytics, health insights based on frequency and weight patterns, and real-time notifications.

AI, Data & Privacy
Caution - data processed in the United States
This robot sends data to cloud servers in the United States. For EU residents, this means personal data is transferred outside the EU. While some companies use Standard Contractual Clauses (SCCs) or other legal mechanisms to comply with GDPR for transatlantic transfers, the data is not under direct EU jurisdiction. EU residents should review the manufacturer's Data Processing Agreement and privacy policy carefully.
How to keep it private
The automatic self-cleaning cycle runs on-device based on the OmniSense cat detection without internet. Weight sensing and cat detection work locally. However, all analytics, health insights, notifications, and remote monitoring require the Whisker cloud service.
Available privacy controls
Core self-cleaning functionality works without the app or internet. The unit detects cat exit and runs the cleaning cycle automatically.
Review and manage stored cat weight and usage data through the Whisker app
The Litter-Robot 4 works as a basic self-cleaning litter box without any internet connection. For privacy, skip the app setup and just use the physical controls. If you want the analytics, know that Whisker stores detailed cat behavior data (visit times, weight, frequency) on US servers. This is pet data rather than personal data, but the usage patterns can reveal household routines. Whisker has no EU-specific data processing.
What this means for EU residents
Whisker stores cat usage data, weight history, cleaning cycles, and health analytics on US-based cloud servers. The app provides detailed dashboards showing each cat visit, weight trends, and usage frequency. This data is used for pet health insights and product improvement.
