The beater bar found and ingested a remarkably long strip of carpet yarn, resulting in a sudden stop and an acute need for disassembly. In the unlikely event that happens again:
- Remove hose
- Release latch to lay hose fitting flat
- Remove two obvious screws
- Pry rear latches adjacent to hose fitting to release rear of top cover
- Pry side latches to release middle of top cover
- Pull rear of top cover away from base
- Disengage latches along front of beater bar
Those places, neatly marked for future reference, with the top cover against the floor:
With the cover off, the beater bar lifts out and you can easily unwind the mess.
