I hate mopping, but I hate mopping robots more. And I especially hate robot vacuum-mop combos. During my years reviewing robot vacuums, I can't count how many times I've had to unhook a minuscule water bin off the bottom of a robot, fill it with a thimbleful of water, and watch it laboriously drag a barely moist towel across my kitchen floor. It never seemed worth the effort when you just could grab a Swiffer. My 7-year-old had just shaken sugar off her toast all over the kitchen floor, so once she was off to school, I moved some chairs out of the way and plugged the mopping attachments onto the X1 Omni's bottom.

Narwal Robotics is a relative newcomer to the household robot market, having been founded in 2016. But you'd never know this was a rookie effort based on the company's hardware. Its first product, the Narwal T10, is a phenomenal robot vac/mop hybrid that delivers several features you won't find anywhere else. But you need to use Narwal's app to control the device, and that experience can be tear-your-hair-out frustrating. As good as the hardware is, no manufacturer should expect its customer to pay $1,199 for its product and then have to wrestle with a half-baked app to use it. This profile shot of the Narwal T10 shows one of its mopping pads in close contact with the floor underneath it.
