Back on target here...
I have an empty house in front, that we use as a guest house. Minimal furniture, hardwood throughout, no thresholds...but a random accumulation of dustbunnies and spider webs since it only gets used every few weeks.
Would the cheapest Roomba or other brand name work to keep this tamed? Can they be scheduled to run different rooms on different days, or do you need to pick it and the base station up and move them around? It's a 2 bedroom, 1 bath, basic 50's ranch home.
