iRobot Scooba And Heinlein's 'Hired Girl' Robot

iRobot's new Scooba floor-cleaning robot is a great idea - Robert Heinlein's! He specified what was needed in his 1956 novel The Door Into Summer. It only took humanity fifty years to go from the Hired Girl robot idea to reality:

What Hired Girl would do... was clean floors . . . any floor, all day long and without supervision... It swept, or mopped, or vacuum-cleaned, or polished, consulting tapes in its idiot memory to decide which. Anything larger than a BB shot it picked up and placed in a tray on its upper surface, for someone brighter to decide whether to keep or throw away. It went quietly looking for dirt all day long, in search curves that could miss nothing, passing over clean floors in its endless search for dirty floors... Around dinnertime it would go to its stall and soak up a quick charge...

The iRobot Scooba cleaning methods are a pretty close match to Heinlein's Hired Girl, performing these actions in a single pass:

  1. Preps - picks up loose crumbs, sand and dirt
  2. Washes - fresh clean solution applied
  3. Scrubs - scrubs while it roams
  4. Dries - picks up the dirty solution, leaving the floor clean and dry.
Scooba's appearance is a pretty close match for its robot vacuum cleaner cousin Roomba.
