Roborock S8 Pro Ultra vs Roborock Qrevo

The Roborock S8 Pro Ultra is marginally better than the Roborock Qrevo. However, the latter is still a fantastic deal and will provide a pretty similar ownership experience outside of a few use cases. The S8 Pro Ultra is the better option for pet owners: its twin roller head is much better at dealing with pet hair, and its brush head lifting system prevents the rollers from getting dirty as it mops. Its Reactive 3D hazard avoidance system is also better at identifying hazards, and the vacuum is less likely to get stuck on obstacles. Meanwhile, the Qrevo's mopping system is better at dealing with dried-on stains. Both vacuums have multi-function docks with similar feature sets, but the Qrevo's dock is taller and narrower, making it easier to fit in a nook between bookshelves or chairs.
