I’m pretty sensitive to noise(have tried a number of different vaccuums in the past.) The best I’ve had so far is a Miele(It’s easy clean as it uses a throwaway bag), great suction, low noise level, you use your foot to retract the chord, likewise, you use your foot to turn it off and on. I’m currently using the cat and dog Miele ... but there are others too for much less cost ...

I also have a Vax(noisier, but also does a wet shampoo which is great!). It too uses a disposable bag for dry vaccuuming.
