Is the Shark UV Reveal good at mopping?The Shark UV Reveal has provided solid scrubbing so far in my testing, and that's all due to the fact that the mop doesn't just drag across the ground. Shark's HyperSonic mopping vibrates more than 100 times per minute while the vac is in motion, similar to the speedy back-and-forth motion you'd use to chip away at something sticky or dried on with a cloth. (We've seen sonic mopping from Shark plenty of times before, but not this intense.)
