Samsung POWERbot R7040 Robot Vacuum vs Roborock Q7 M5+ Robot Vacuum and Mop

The Roborock Q7 M5+ is the stronger pick for most people. It vacuums and mops, has LiDAR mapping that works in the dark, and its auto-empty dock holds dirt for weeks. The Samsung POWERbot R7040 is a simpler dry-only robot with a wider 11 3/8-inch cleaning path and a low 3.8-inch body that fits under more furniture. Owners praise the Samsung's corner blade and easy filter cleaning but report weaker suction and no mop. The Roborock wins on features and hands-off upkeep; the Samsung wins on slim clearance and simplicity.

• Choose the Samsung POWERbot R7040 if you want a low-profile dry vacuum that slides under low furniture and you don't need mopping or an auto-empty dock.
• Choose the Roborock Q7 M5+ if you want vacuum and mop in one robot with LiDAR mapping and a dock that empties itself for weeks.
