Note:   The ATO requires at least 1 float switch, and 2 other sensors to function, another optional sensor can be added to monitor the reservoir or used as additional protection for the ATO. The sensors displayed below are readily available and all compatible with the system however the Optical Water Level Sensors are recommended for the ATO feature and the Non-Contact Water Sensor is great for monitoring the reservoir. The sensors available do have short cables so you will likely need to extend them.

2 Year Warranty

Like the industry leading competitors you can be at ease with your Robo-Tank ATO System as its comes with a 2 year warranty, if the ATO module fails simply contact us and ship it back and it'll be repaired or replaced in a timely fashion. Please note the warranty doesn't cover abuse or water damage and the water pump, power supply and sensors are only covered for 3 months.
