Long story, but our concrete balcony was pitched incorrectly. Not an easy or cheap fix, so living with it for now.

I would love a robot wet/dry vac that could vacuum up the water into its tank. I'm not aware of any that I could find.

I think there might be several cordless wet-vacs that I could use, but just like inside the house, I'd love for an autonomous robot to do the work.

Any suggestions?
