Two additional tips that may be helpful:
1. I used a dryer lint brush (long, small diameter, and somewhat flexible) to clean/clear several of the passages that were too deep or long to dislodge items that were potentially causing my Dyson to loose suction.
2. My filter had gotten a lot of buildup underneath the blue mesh top. I'm ordering a new filter but in the meantime I cut the mesh open, cleared the buildup, and stitched the mesh back together so I could use it.
Successful return to full vacuum suction.
Thanks for everyone's advice
