Ok so I have a Robbie Jr and thought it was too small to mod. I'm looking for ideas but I just saw irobot scooba and realized its so simple I could for sure do something better! I.have every bit of confidence. A scooba has a spray bar , stationary brush and squeegee vac. Im already looking at motorized brushes 4 to 5 inches to fit in him. Any suggestions welcome.

Welp welcome to the club, bout time you decided to mod him. Didn't feel like uploading your robie pic, or they just look the same lol?
I already took the robie apart and it felt right to have a pic of.little guy together lol.
