PSA: I taped a $1 fridge magnet to my Roomba and now it hauls my lost earrings back home
Sounds dumb, but my $18 gray one kept vanishing under the couch in my Austin apartment, so I zip-tied a magnet to the bumper as a joke and it dragged three earrings and a bobby pin into the open after one run. What weird stuff have you strapped to a vacuum to make it useful?
