The Vacuum Cleaner
The ability to program those round, robotic vacuums to clean when you're not at home already exists. But that hasn't stopped vacuum manufacturers from creating mobile apps to program cleaning on the fly. LG Electronics' latest Smart Hom-Bot Square adds a smartphone app to control the little cleaner when you just can't find the remote that came with it. One true added benefit of an app-controlled vacuum? Diagnosing mechanical difficulties and upgrading its software.
