My household vacuum cleaners have almost always been corded (with the exception of a couple battery powered ones I had 5 or 10 years ago). Granted, I didn't shell out several hundred dollars for the cordless ones, but dead batteries and replacements got old after the first round so I've stuck to corded ever since. It's just not something I ever really had a problem with. The cords are typically quite long and I never have to worry about battery capacity or lifespan.
I was referencing GP's Festool comment - Festool does make great stuff, but in the vacuum space they mostly make dust collectors for woodshops and shop-vac style shop vacs -- not the household-style vacs we're talking about.
