Clean Water Sensor (Two Detection Points) - HiZero F803 Bionic Mop Attachments The housing forms the bodyMonitoring the fresh water tank on the HiZero F803 Bionic Mop, this replacement clean water sensor (part #3400002401) uses two detection points to track the water level. It tells the machine when clean water is present and when the tank runs low. A sensor that fails can misread the level, so the machine may stop feeding water, run dry, or report an empty tank that is actually full. Fitting the correct two point sensor restores accurate level detection
