The Roborock Q5 Pro and Roomba j7+ battle — save $150 without sacrificing cleaning power

The Roborock Q5 Pro compares pretty directly with the Roomba j7+, and the headline number is that you can save about $150 without losing cleaning power. The j7+ has the famous P.O.O.P. Promise and iRobot’s brand cachet, but the Q5 Pro brings stronger suction, LiDAR navigation (faster and works in the dark), and a larger dustbin. Your call depends on whether you’re paying for brand trust and object avoidance (Roomba) or raw specs and mapping speed (Roborock). For most buyers, the Q5 Pro wins on value — more features at a lower price.
