I was of a similar attitude to you until I tried and failed to get a decent cordless vacuum cleaner that has a proper wall holster (i.e. putting it in/out of the holster also plugs/unplugs the charger)

I went through several other brands (both well known and no-name things from china) and then returning them to amazon because they were either just crap at cleaning, and/or the wall holster was a glorified hook that required you to put it in the holster and then still plug it in too as a separate step.

I finally gave in and paid a little bit more for a dyson cordless stick vacuum and it has been really quite excellent and I cannot fault it. It always gets a lot more "out" of the carpets than our previous vacuum, and the usability of the wall holster means it is super-fast and easy to just grab and go without faffing with cables (vital for me with a small kid - we're vacuuming multiple times a day)
