Why is the green indicator light flashing?
The green indicator light flashes for two reasons: Rapid flashing indicates the sensors are blocked, which occurs when the cat is inside the litter box. If the indicator light is flashing rapidly and your cat isn’t inside the litter box, it’s possible urine or other debris is blocking the sensors. To clean the sensors, dip a cotton swab in isopropyl rubbing alcohol and gently swipe inside the sensor holes on both sides of the litter box. After cleaning, unplug the litter box then plug it back in. The indicator light should return to a steady green. Slow flashing indicates the litter box is in countdown mode, which occurs after your cat uses the litter box. The rake will sweep 20 minutes after your cat uses the litter box (or 5, 15, or 20 minutes after your cat uses the litter box if you have ScoopFree Ultra). The indicator light will return to a steady green once the rake is back in its home position.
