I have a robot vacuum that I haven't used in several years (once I started living with another person and several cats, it became impractical to keep the floors clear enough for it to work well). So I took her down to the basement to see how she'd handle sawdust and metal chips.
Results so far are... not promising, because I *also* leave shit all over the floor down here :D
(also she found a dead spider and flung it at me)
