Roborock Q5 Pro vs Roomba j7+: Save $150 without sacrificing cleaning power

The Q5 Pro wins on value — stronger suction, LiDAR navigation, and a larger dustbin for about $150 less. The j7+ has the P.O.O.P. Promise and brand cachet, but the Q5 Pro maps faster and works in the dark. Most buyers should go Roborock unless object avoidance is a must.
