🥈 Best value: Roborock Q7 L5 Robot Vacuum and Mop Combo

🐶 Best for pet hair: Shark Navigator Robot Vacuum with Self-Empty Base

My picks by situation

Best overall: Roborock Q10 series

Best under ~$250: Roborock Q7 L5

Best for pets: Shark Navigator Self-Empty

Best “just works” option: iRobot Roomba 104

Best cheap but decent: eufy Clean L50 Robot Vacuum (good if you mainly need daily dust pickup and don’t need advanced features)

For most people spending $200–$300, I’d choose Roborock Q10/Q7 over Roomba or Shark because the mapping and cleaning efficiency are usually the biggest quality-of-life improvements.

If you tell me your floor type (hardwood/carpet), pets/no pets, and apartment vs house, I can narrow it to one model.
