The Roborock Saros 20 does all three, outpacing the Eufy 11S MAX on connectivity, mopping and smart-home integrations. The Saros 20 runs LiDAR navigation with no-go zones, vacuums and mops in the same pass, and its dock washes, dries and empties itself, while the Eufy 11S MAX has no Wi-Fi, no app and no mopping at all, relying on a simple remote instead. The 11S MAX answers back as the more affordable option with a larger onboard dustbin, so it goes longer between manual empties. Shoppers who want a genuinely hands-off, app-controlled clean should choose the Roborock Saros 20; anyone who wants a cheap, no-frills vacuum for a small space should stick with the Eufy 11S MAX.
