11,000 Pa robot vacuum and mop bundled with a handheld vacuum that empties into the same all-in-one hub.
Verdict: Great if you want a robot and a handheld that share one dock.
The DEEBOT T30S Combo pairs an 11,000 Pa robot with ZeroTangle, TruEdge adaptive edge mopping and auto mop lifting, plus a cordless handheld vacuum; both self-empty into the shared station, which also washes mops with hot water.
