Roborock S8 Pro Ultra vs Roborock Qrevo Pro

The Roborock S8 Pro Ultra is marginally better than the Roborock Qrevo Pro, though the latter is a good choice if you're looking to spend less without skimping on features. The S8 Pro Ultra's twin roller head is much better in clearing away pet hair, and its brush head lifting system prevents the rollers from getting dirty as it mops. It also does a better job of dealing with solid debris on most surfaces. Its Reactive 3D hazard avoidance system is also marginally better at identifying hazards, though neither vacuum is especially good in this regard. That said, the Qrevo Pro's mopping system is better at dealing with dried-on stains, and its FlexiArm design allows it to clean far more effectively along walls and in corners. Both vacuums have multi-function docks with similar feature sets, but the Qrevo Pro's dock is taller and narrower.
