We know, we know — the original Roomba saves children from peril , plays real-life Pacman , and steals its owners’ hearts away , but let’s give LG’s refreshed autonomous robovac a chance, shall we? Now equipped with two cameras (claimed to be an industry first) and lowering operational noise to a more bearable 50dB, the RoboKing is back in town and pining for your attention. It’s more compact than its previous iteration, stretching up to only 90mm, and it’s also said to be 30 percent faster on the job.
