Pivot on motor bar doesn't move freely.

Picture showing the part I'm specifically talking about.

Just got a V11. Vacuumed a few rugs and now the pivot point on the cleaning head doesn't move freely. If you extend the vacuum away from you, the head stays tipped up a t a 90 degree angle. I tried to blow dust out of there with an air compressor but it still feels like a plastic-on-plastic rub.

Anyone else dealt with this? Clean it more? Lube it with dry lube? Support/warranty?
