5 of the best robot vacuums

iRobot Roomba 770 £420
Looking like R2-D2's plasticky girlfriend, the iRobot's highly evolved sensors mean you don't have to fret about it crashing into anything. Quiet, powerful and long-lasting, the Roomba's one spinning brush sweeps up all your debris and its whopping battery means it keeps going until the floor is spotless. The lord of the future-vacs.
