I picked up a slightly used SEBO D4 yesterday. It is amazing. If Porsche built vacuums, this would be it. All of the accessories are really easy to use, and the hose is long, tapered, and free to rotate at the handle end. 40' cord, and no tools required to remove and clean the rotating brush. The hose, handle and powerhead are much lighter than my Kenmore. It is just much better engineered than my Kenmore or Hoover vacuums. the only downside is the cost, but I got mine for just a little over 1/2 the price of a new one, and it does not have many hours on it. Still looks new.
There are lots of vacuum cleaner. People buy and use them according to their needs. But it's hard to find out the reliable and cheap one. I recently bought a new one https://devices4home.com/best-upright-vacuum/ Looks good and effective with cheap price as well.
