The Sensor Flush uses infrared sensors to detect motion above the cistern and flush the toilet in response. This automatic function reduces the need for physical contact, which is not only more hygienic for the user but is also considerably easier for those with limited dexterity to operate. Available separately, the sensor flush is compatible with Navlin and Livenza Plus cisterns with the raised push-button flush operation and can be easily installed in place of the push-button mechanism.
