eufy Omni S2
Eufy's most powerful flagship — 30,000Pa AeroTurbo, HydroJet 2.0 roller mop with 60°C hot water sterilization, and a 12-in-1 dock with built-in fragrance.
iRobot Roomba Plus 405 Combo
A solid mid-tier Roomba that finally brings LiDAR navigation and a self-washing dock under $500. But weak deep-carpet performance and zero obstacle avoidance make it hard to recommend over the Roborock Q Revo or Dreame L40 Ultra at the same price.
