Roborock S7 MaxV vs Roborock S8 Pro Ultra

The Roborock S8 Pro Ultra is a slight improvement on the Roborock S7 MaxV, though the latter is still a good option. The S8 Pro Ultra's brushroll lifting system prevents its rollers from getting dirty as it mops, though the mopping system isn't quite as effective as that of the S7 MaxV. The S8's twin brushrolls also make it far more effective in dealing with pet hair, and its fast-charging system means that it can replenish its battery much faster than the older S7. Meanwhile, the S7 MaxV has a color camera instead of an infrared system, and you can use it as a roving security camera by looking through its camera in its companion app. The S7 MaxV also has a removable water tank instead of the built-in component found on the S8 Pro Ultra, making it easier to check and clear out blockages. Lastly, while we didn't test it in this configuration, it's worth noting that you can bundle the S7 MaxV with a multi-function dock that's similar to the one bundled with the S8 Pro Ultra.
