LG CordZero ThinQ

The LG CordZero ThinQ uses dual cameras to build detailed maps rather than relying on single-sensor navigation, giving it better accuracy across large floor plans. The auto-empty base holds 60 days of dust before needing attention, a genuine convenience for bigger homes where the robot collects more debris between manual empties. LG's app sets room-specific cleaning strengths and no-go zones, so you control which areas get deep cleaning and which get a quick pass.

Large homes benefit from the CordZero's ability to sustain suction throughout multi-floor runs without losing power as the bin fills. The independent floor mapping prevents wasted coverage, since the robot won't vacuum the hallway twice when moving between levels. Battery endurance on sprawling layouts means fewer recharge cycles during a full cleaning.
