The powerhead fitted to all Felix models (Not Dart) is the ET-1 (premium) type which has a foot pedal recline similar to the X series. The ET1 features a manual 4 position height adjustment dial to suit different flooring types. LED control panel indicates brush roll monitoring at all times if height adjustment is set too high and automatic shut off of the motor if brushroll becomes obstructed, strained or jammed. The brush roll motor can be switched off manually for use on hard floors, and automatically shuts off when the machine is in the upright locked position. Like the X series, the brush roll can be easily removed for cleaning or replacement.
