One day they'll enslave us all, but these robot dust-munchers have carpets to clean first.
iRobot Roomba 770
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.
OK so it's not quite a robot vac but the Litter-Robot can cosy up nicely in your 'bot cupbaord. This automated litter cleaning pod means that you'll never again have to deal with your cat's litter tray – all you need to do is swap the waste bag every few days.
Samsung NaviBot Silencio 8895
So smooth you could slim it across a lake like a stone, the NaviBot Silencio – as its name suggests – is all about being quiet while still offering sufficient cleaning power. It has 39 sensors and a Visionary Mapping System which shoots 30 snaps a second to map a room. Just watch out for tangled cables.
The Neato's military design and big suspended wheels would be just as at home on rocky terrain. But the Neato is pretty clever – it uses a laser system to accurately map out the room to avoid table legs and other obstacles. There's a top-loading dust tray and it's smart enough to find its way back home to recharge when it's running low on juice.
So you've sucked up all the dust inside, turn your attention to messy lawns with the Robomow RL2000. This mower-bot is ideal for lazy landowners – peg down a perimeter wire and it'll trundle around, making the lawn look pristine before returning to its charging base.
