What do you think of them.

SWMBO bought $1,000 worth of them, and I need a good argument when
she tells me I don't need any more tools.

Are they worth that much $$$ ? They sit idle 99% of the time, full
of dirt. Must work some kind of good, they're always clogged. But I
live on a sand dune, so around here, the coffee pot is even a good
dirt collector.

An electrostatic air cleaner on your forced air furnace would actually clean the
air, and maybe be cheaper.
