Give her the gift that sucks year round.
Seriously, mid-century man, were you even trying? I guarantee you that no 1950s woman got down on the floor and gently stroked her new Hoover. She may have been grateful to get rid of the old canister vac that belched a huge cloud of dust every time she stomped on the foot switch, but that’s a long way from “just what I wanted, honey.”
That being said, my Roomba just died, so yeah. I’d be pretty jazzed to get a new vacuum for Christmas.
