eufy Omni S2 review: robot vacuum with roller mop and all-in-one dock

The eufy Omni S2 is a premium robot vacuum with a roller mop and the successor to the eufy S1 Pro. Its all-in-one dock empties the dustbin into a dustbag, refills and drains water, washes the mop with hot water and dries it with hot air, while also making a disinfecting solution and diffusing fragrance. It maps with a 3D time-of-flight sensor instead of LiDAR and spots obstacles with an RGB-D depth camera.

• Dock washes the mop with hot water and dries it with hot air
• Disinfecting cleaning solution is made from tap water
• Built-in fragrance diffuser scents the room during cleaning
• 3D ToF mapping plus RGB-D depth camera for obstacle detection
