The new bilge pumps feature an internal level sensor that activates them when the water reaches a height of 5 cm and deactivates them when it is removed (Auto Sense Intelligence). In case the level sensor becomes contaminated with debris or polluted water, the backup function prevents continuous operation of the pump, protecting the battery while maintaining automatic operation. The pumps are equipped with a check valve to prevent backflow of water, which can cause unpleasant odors.
