What testers say about the Dyson 360 Vis Nav
The Dyson 360 Vis Nav is a vacuum-only robot without a mop or a self-emptying station: it charges on a simple dock and you empty the bin yourself. Dyson bets on suction, with a D-shaped body and an extra-wide brush bar that combines three kinds of bristles, and navigates with a 360-degree camera instead of lidar. Vacuum Wars tested it for weeks and calls it one of the most powerful robots available today, with clear shortcomings.
The testers praised the vacuuming itself: on hard floors and carpet alike it picked up fine to coarse debris in one go, and in the test with sand embedded in carpet it scored above average. Even in its lowest setting the suction exceeds what many robots deliver at maximum, and in that setting battery use is frugal too. An extending side duct sucks right up to the baseboard where other robots use a side brush.
The criticism is about navigation and run time. The camera navigation took longer than usual to map, the map was unclear and did not improve by itself, and coverage varied from run to run. At full power the battery drains fast, giving one of the worst battery-efficiency scores Vacuum Wars has recorded; the robot then recharges and finishes later. The app covers the basics but less than the big rivals' apps. This is a robot for people who put suction above everything and do not mind emptying it themselves.
