The sensor must be blocked for at least 10 seconds while your cat uses the litter box. As your cat exits the box, the sensor becomes unblocked and initiates the Cleaning cycle.
Once initiated the Cleaning cycle will officially begin after 10 minutes to ensure your cat is no longer in the box.
Note: If you cat re-enters the box during the wait time, the sensor will trigger again and the 10 minutes will start over.
During the Cleaning cycle, the automatic rake will move forward and back to scoop waste clumps into the waste receptacle, which will then keep waste and odors contained until it is time to replace it.
CAUTION: Not intended for use with kittens or cats less than 6 months or weighing less than 5 lbs. If your kitten or cat is under 6 months of age, leave the unit UNPLUGGED and scoop waste until the kitten or cat is 6 months old.
