Automatic vacuum cleaners, like the Roomba, can't usually do stairs. But the Slinky Roomba can! Simply set it on the top step and go make yourself a cup of tea.
Looking like a hinged L-shape, the Slinky Roomba sidles left-to-right until the step is clean, whereupon the motorized hinge unfolds and the entire contraption journeys, slinky-style, to the step below.
Once the cleaning is done, Slinky Roomba can be set to walk aimlessly around the house in an inching, caterpillar-like motion to entertain young children.-- mitxela, Oct 28 2015 Skirting_20Board_20Vacuum_20Roomba here's its best friend [xenzag, Oct 29 2015] Brilliant!-- blissmiss, Oct 28 2015 I'd like one to slink hand-to-hand when there are no automatic handwashing breasts in the toilet.-- 4and20, Oct 29 2015 Totally impractical - (that's a big compliment from me) Here's a piece of a croissant - rem to eat on the stairs, to give your new apparatus the opportunity for an outing!
