Samsung NaviBot Silencio 8895 £500
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.
