Self-emptying robot vacuum and mop with a fully retractable mop pad that lifts onto the top of the robot on carpet.
Verdict: Clever mop retraction and good obstacle avoidance, though suction trails newer rivals.
The Roomba Combo j7+ vacuums and mops in one run, lifting its mop pad fully onto its back when it reaches carpet. It identifies and avoids obstacles like cords and pet waste, uses smart mapping and empties into a Clean Base.
