How to use Cloud SprayUpdated an hour ago
Once set up, you have two ways to use it:
Manual: Press the Cloud Spray button on your remote to dispense foam on demand.
Automatic: Hold the Cloud Spray button for 5 seconds to toggle auto-activation. When enabled, the toilet beeps once and foam is dispensed automatically after each use. Hold again to turn it off (two beeps).
