While there is a certain level of innate technical mindedness that people have… Being willing to try to fix it, and the lessons you’ll learn from either fixing it or not is huge. Regardless of outcome hopefully the experience will be somewhat fun and pay dividends in terms of being able to recognize where vacuums get bound up with clogs, hair, etc. Occasional deep cleaning will make all the vacuums in your future live longer and suck harder.
Projects that are ‘either it gets fixed or tossed’ are great, there’s so little pressure, and so much you can learn.
Feel free to ask more specific questions if you get deep inside it and come up with them!
