Pride. Pride in figuring out that the vacuum cleaner is not broken, it just has a clogged lower tube. (Who knew that they even had a lower tube? Vacuum surgeons? Certainly not me, until in an act of desperation, I Googled for help.)
A Moment of Silence. A moment of silence for all of our previous vacuums that probably died from a clogged lower tube, but were misdiagnosed.
A Lesson to You. A lesson to you to always check that lower tube.
