You will also want to make sure the filter isn't clogged up. Most overheating is going to be an airflow issue. You can also look up online how to pull it apart and check components. You may also have a loose power connection somewhere. Make sure the vacuum is unplugged before you mess with it.

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!
If you know someone with an air compressor, try blowing the dust out of the motor. Check for hair wrapped around the metal shaft of the motor.
Also check for hair wrapped up around the brush (take off the bottom plate and remove the whole brush, there's usually a lot of crap around the ends where the brush spins).
There's a TV series called "The Secret Life of Machines" from the 1990s, which has a whole 30 min episode about vacuum cleaners. I think it's wonderfully presented - funny, clear, entertaining, gives a good understanding for how to grapple this sort of problem. https://youtu.be/CJlrbMHLBd4?si=G2X40txUnYn3iUA1 I think mains powered vacuum cleaners haven't changed much since, so it'll probably still be good information, although it won't get in to battery powered models, because those are newer.
That sounds good, I'll check it out. Thanks.
Check for debris and cloggs anywhere you can
Just to echo what everyone else is saying, it looks like there are a bunch of guides on how to disassemble your vacuum online. Follow one of those as far as you're comfortable to go, and clean everything along the way.
Yep you can! Just make sure you don't work on it plugged in and be careful around any capacitors if you've run it recently. They can hold charge
Good advice 👍
