CLEANING PROWESS Average. It picked up less coffee powder than the LG, Neato and Irobot machines. It comes with two side brushes but these were hit-and-miss – they swept some crumbs into its path and brushed others aside.
SENSITIVITY TO OBSTACLES It avoided walls well but hit low furniture lightly.
EASE OF USE The remote control and the LED touch screen were intuitive – it was the only machine that I could use straight out of the box, without having to refer to its manual. But there were minor inconveniences like having to plug the cable directly into the vacuum cleaner to charge it and a less convenient slide-out dust bin. NOISE The second-quietest.
VERDICT A relatively muted and fast-charging robot that is easy to operate. *All the vacuum cleaners come with boundary markers – magnetic strips or small lighthouse-shaped tools to confine them to an area.
