SEBO Brush Roller Release S...

Product details
Sold one at a time for a single repair, part 20121 is the spring sitting behind the brush roller release on a SEBO 370 COMFORT. It supplies the tension that returns the release to its seated position each time it has been used.
When that tension goes, the release stops snapping back. The roller becomes awkward to free and awkward to reseat, and a task that should take seconds turns into a fight every time hair needs clearing off the brush. It is one of the smallest items in the entire machine and one of the easiest to overlook, because the symptom feels like a problem with the button rather than with the spring behind it.
One spring, one machine: it is listed for the 370 COMFORT. Buying singly suits a household fixing its own vacuum, while a workshop turning machines around regularly is better served by the ten pack under 20121ER. The spring itself is identical either way. It is small enough to be worth handling over a tray rather than over a carpet, because a release spring dropped into pile is a release spring gone. Anyone searching for a SEBO 370 brush roller release spring or a 370 COMFORT roller spring is in the right place.

Fit it while the roller is out and clear any wound thread off the shaft and the bearing seats at the same time. A spring that has been stretched back into shape rather than replaced loses its tension again quickly, so it is worth putting a new one in while the machine is open. A genuine SEBO service spring, out the door in 2-5 business days.
