Roborock Saros 20 Sonic vs Shark PowerDetect Self-Empty

Vacuum-and-mop combo against vacuum-only robot: the Roborock Saros 20 Sonic wins this pairing against the Shark PowerDetect Self-Empty on nearly every measured point, from a longer battery runtime and dual-band Wi-Fi to a larger onboard dustbin and, above all, sonic mopping with a dock that washes and dries the pads automatically. Its smart-home reach also stretches further, covering Apple HomeKit, Samsung SmartThings and Matter alongside Alexa and Google Home. The Shark PowerDetect Self-Empty holds onto one real advantage, a typically much lower price, since it skips mopping hardware and premium navigation entirely. Households that want vacuuming and mopping in one machine with the broadest smart-home support should choose the Roborock Saros 20 Sonic; buyers who only need dry vacuuming at a lower price should pick the Shark PowerDetect Self-Empty.
