This is a “hat” roughly in the shape of the iRobot Braava Jet M6. When used by itself, a child can freely push it without burning out the motors of the real thing. Tape a paper towel, wipe, Swiffer pad, or similar where the mopping pad would typically be and they may marginally help clean the floor too.

I originally designed it with this AmazonBasics RC toy car in mind. When used together, you now have a completely driveable mop – something iRobot doesn't give you themselves. Since that model appears to be discontinued, I have included the Fusion 360 sources so that you can customize the cutout for any RC car you have on hand.

Print upside-down (i.e. with the top of the “robot” on the print bed) at the thickest layer height your printer supports. Supports not required.

Spray nozzle not implemented.
