Roborock Saros 20 vs Shark PowerDetect Self-Empty

A dock rated to go roughly two months between empties is just one part of the case for the Roborock Saros 20 over the Shark PowerDetect Self-Empty, which also loses out on battery runtime, dual-band Wi-Fi, onboard dustbin size and, most notably, mopping, since it is a vacuum-only machine with no washing or drying dock of its own. The Roborock Saros 20's smart-home reach goes further too, adding Apple HomeKit, Samsung SmartThings and Matter to Alexa and Google Home. The one place the Shark PowerDetect Self-Empty wins outright is price, where it typically costs considerably less. Buyers who want a full vacuum-and-mop robot with the broadest smart-home support should choose the Roborock Saros 20; anyone who only needs dry vacuuming at a lower price should pick the Shark PowerDetect Self-Empty.
