$40
An older Roomba 981 that still cleans well. It connects to the app, which you can use to set a schedule for cleaning.
I've replaced the battery once and regularly replace its parts (rollers, spinning brush). It is older, so the charging pads and dust sensors need regular cleaning.
Pickup at the California Ave Caltrain station parking lot.
$40 OBO.
