Alison Keenan was just on with that annoying little man that chucks dirt on the floor. They were demonstrating some sort of round robot automatic vacuum cleaner. The idea is that you leave it while you go out and it goes round and round, vacuuming the floor. I quite like the idea of this device and it looks fun. Has anybody used them? Are they any good? I saw something similar a couple of years ago but it was expensive. It looks like it might be good for my laminate floors. Thank you for any information.
