Roborock Q5 vs Roomba 694: Lidar navigation wins for mapping, but both are only good on low-pile carpets

The Roborock Q5 has lidar navigation for smart mapping, while the Roomba 694 uses random bump navigation. Both have decent suction and rubber brushrolls that resist tangling, but neither handles high-pile or shag carpets well — they’re best on low to medium-pile carpets for daily dirt and pet hair.
