As TechRadar's Homes Editor for floorcare I've seen my fair share of unusual contraptions among the ranks of the best robot vacuums – but I've never seen anything quite like the xLean TR1. This is a robot vacuum that can also be used as a manual stick vacuum – and it can mop and vacuum in both modes.
The shapeshifting design isn't the only interesting thing about this gadget though: it's also kitted out with a 'self-evolving intelligence system' that means it learns your own cleaning techniques while it's being used in manual mode, and can then replicate them in robot mode.
