I have a new Kenmore Progressive canister vacuum. Apparently my wive vacuumed up a purple marker the other day that is stuck in the flexible tube. The bend at the end of the tube (where it connects to the canister) is preventing it from coming out. Something else was sucked up behind the marker and now the whole thing is clogged up. Is there any way to remove the ends of the flexible tube to clear the blockage. I haven't had any success.

Thanks for your help.

Frustrated new vacuum owner.
