There's no doubt that its unique UV stain detection and meticulous scrubbing capabilities earn it lots of points in the sanitation department. But the Shark UV Reveal's mop doesn't rinse itself in real time, while the roller mops I've been testing do. Its frequency for returning to the dock to wash the mop can be toggled to as low as 15 minutes, but that's plenty of time to spread something sticky or smelly across my entire kitchen. At $1,299, it's valid to expect a mop monitoring system that automatically sends the robot back to wash the mop if it gets too dirty. Not that your UV Reveal will have the opportunity to smear large spills around, anyway — it's not really built for soaking up messes larger than a few droplets. (The instruction booklet specifically notes to avoid "liquids.")

“The past five to seven years have been very hard on us personally,” Darrel Larson, a vice-president of operations, told me. Larson, who grew up on a farm in North Dakota, has a rangy frame and a folksy manner. We were standing on the floor of the building where the 777 is constructed—the largest factory in the world by volume. It’s a vast, open hangar, two-thirds of a mile long and a third of a mile wide, subdivided by rows of glass-walled offices. A system of tunnels runs beneath it, and a network of rails above, hung with gantry cranes that can lug an eight-ton engine across the floor. The factory runs around the clock, yet it was eerily quiet. The planes are mostly assembled from modules made at other sites nearby, and pieced together in a strictly orchestrated sequence. Shrink-wrapped airplane lavatories were clustered along the perimeter, next to carts full of bins with numbered parts. It was the world’s most sophisticated Lego set.
