Cordless Upright Vacuum Cleaner

I have a built in central vac, and a dyson cordless vac. I can count on one hand the times that we used the central vac. The dyson does an excellent job, and the runtime is long enough to do the entire coach. I have the charging base permanently installed in the closet. It is a simple 1,2,3 to unhook and use and then put back on the charger. The central vac hose is a pain to hook up use and put back. The hose is heavy and ungainly to get back into the storage bag. The only con to the dyson, is that you can't leave it in the coach if the temps go below 40, as the battery is extremely susceptible to cold. I had one fail, which they replaced with much coaxing. It is now on the winterization checklist.
