What do you call a vacuum cleaner that works perfectly in the store demo but clogs on the first bedroom carpet?

We tested three models at the big-box store. Watched the salesperson glide it across that little patch of fake living-room rug like it was a hovercraft.

Brought it home, plugged it in, rolled it six feet down the hallway.

Punchline

A sock magnet with a warranty.

The clog-release hatch is now our most-opened drawer.
