If the brush roller is obstructed on the Sebo ET-1 or ET-2 the power head will shut off in three seconds, the amber light located on the top of the power head will illuminate, and the brush roller will stop rotating. Sebo's overload protection system reacts quickly to shut off and protect the belt and motor if jammed. When the clogging object is removed and reset button pressed, vacuuming can resume.
Both the Sebo ET-1 and ET-2's brush height may be adjusted with a manual 4 level height adjustment. The amber light located on top of the power head will also illuminate if the height setting is too high or if the brush roller is worn. When the machine has its handle in the upright-locked position, it is designed to shut off the brush roller. The green light does not illuminate in the upright position. The green light will illuminate only in the operating position.
This fine-tuned crafted motor is so powerful and so well built it can truly last anywhere between 40 to 50 years, easily. That's what German engineering's all about. Sebo power nozzles are built so well they guarantee their belts forever and provide a 15 year motor warranty. Sebo central vacuum carpet nozzles proved years of durability and reliability for any central vacuum owner!
