SEBO Power Head Cover for the AUTOMATIC X4 Boost — Complete, Graphite

Position 100 in SEBO's exploded parts diagram for the AUTOMATIC X4 Boost is the complete power head cover, and part 50799GS is the graphite version of it. The shell sits over the brush roller drive, keeping dust away from the belt and gears underneath.

When the plastic splits or a clip goes, the cover stops pulling down tight and the head loses its seal against the base. Since the part comes finished and complete, the repair is a straight exchange with nothing to recover from the damaged shell. The symptom to watch for is a head that no longer sits flat on carpet, often with a knocking sound as the loose corner lifts and drops.

Being sold complete is the useful part of this listing. The alternative on a cover is a repair that reuses the very clips and locating tabs most likely to have broken, which is why SEBO lists the shell as one item at a single diagram position rather than as a handful of separate moldings. It arrives in graphite, finished, and goes on as the factory fitted it.
