Who should choose Xiaomi Vacuum Cleaner G20 Max
Xiaomi Vacuum Cleaner G20 Max is the stronger fit when its leading dimensions match your primary use. Configuration checks: Compare like form factors such as cordless stick or wet-dry units, then verify the exact model code, floor-specific heads, suction rating method, runtime by mode, body and in-hand weight, filtration and bin, wet cleaning, dock functions, and battery or accessory count. Then ask whether the product removes a concrete problem with the device you already own. If the gap is small and there is no real pain point, waiting for a price drop or a change in workload can be more rational than upgrading for novelty alone.
Who should choose Roborock Flexi Pro
Roborock Flexi Pro is the better fit when more of its strengths overlap your priorities and its weaker dimensions remain acceptable. Switching costs: Include replacement batteries, filters, brushes or rollers, dust bags, mop pads and detergent, removal of the old mount, dock floor space, outlet and water workflow, and access to warranty service. A higher total can still deliver lower practical value when that burden is large, so compare the score lead and switching cost on the same baseline.

Scope and limits of this comparison
This comparison is a structured decision aid built from published specifications and stored representative configurations. Scope and limits: Direct suction comparison is limited by differing units and measurement points; real performance changes with floor drag, head, power mode, filter loading, battery aging, home layout, and pet hair. The scores are relative indicators for setting priorities within one category, not an absolute quality ranking. When a new configuration or verified specification becomes available, the catalog and its comparison pages are regenerated together.
