Arch right after we bought the coach Kathleen decided that the hose was a pain in the butt and it was easier to take something out of the rear closet rather than having to go underneath the coach from one of the bays and pull out 20 ft of hose and a wand. I can't say for certain but I think we bought a Dyson plug in.
We remove many built in vacuums in homes during remodels. Dyson has changed the cleaning industry with their powerful "outsize" battery vacuums. We have a V12 one in the rear closet. So much easier. Lugging a hose around seems very 1970's!
