Most, if not all, of the first generation robot vacuum cleaners came in only one shape – it was circular in nature, and they generally pitter pattered around the home while making short work of dust bunnies. It then dawned upon the folks over at LG that a square shape would do a much better job at cleaning corners compared to a circle, resulting in the LG Hom-Bot robotic vacuum cleaner. We do wonder, however, why not come up with a triangle shaped robot vacuum cleaner to boot? That would also be able to cover corners effectively, and would be handy for small one-bedroom apartments.
