There are some bypass units like Cyclovac where not only they use suppressors to help keep the noise down but they can also catch some carbon dust that would leak out of the brushes, they also use a carbon filter to catch whatever else it would collect. I don't see heat being a huge issue with bypass motors, especially since they're designed to help cool the motor down. And there are some bypass motors like the MD SilentMaster S900r/r2 (Dual Motor) where all of the exhaust exits out of the motor completely, also more powerful and just as quiet as my uncle's MD Flo-Master F650t. I don't believe all thru-flow motors are quieter than bypass motors. But yes they are inexpensive to replace.
The Eureka is the unit we have over in our storage shed, it doesn't get used much. If someone used that vacuum while the exhaust is blocked, they would for sure stress the motor and possibly melt some of the piping. I could put a vent cap in if I wanted to but I have found that they can break overtime so it wouldn't really make much sense for me to put one in if we're not going to use it very much.
And there are few companies like Sebo that sells cloth bags using some recycle material, I also don't see how that is not environmental friendly.
