The iRobot Roomba Combo j9+ brings iRobot's best-in-class obstacle avoidance to a vacuum-and-mop combination — and crucially, its mop arm retracts completely off the floor when the robot detects carpet, so it genuinely vacuums dry on carpet without you having to manage which mode it's in. For Canadian homes with mixed flooring, this is iRobot's smartest robot.

"The mop pad retraction is the feature that sold me. Half my house is hardwood, half is carpet — this is the first robot that handles both without leaving wet marks on the rugs."

"Expensive but it's the only combo robot I trust not to wet my rugs. Every other one I tried left damp spots on the carpet edges."

The Combo j9+'s retractable mop arm (which lifts the mop pad over carpet) is a sophisticated mechanism; r/RobotVacuums documents concerns about long-term reliability of the retraction motor and arm assembly.
Source: r/RobotVacuums, r/iRobotThe Roomba Combo J9 is the most complete robot vacuum-mop package iRobot has ever made. The retractable mop that lifts onto the robot's back when hitting carpet is the feature that makes it genuinely practical in mixed-floor Canadian homes — no wet carpet, no manual intervention. Combined with the J-series obstacle avoidance, it's the premium choice for households that need both vacuuming and mopping to just work without thinking about it.
