SwitchBot S10
Only one whitelisted outlet, TechRadar, has hands-on coverage of the exact SwitchBot S10, and it is an IFA 2023 demo preview, not a full lab test. It calls the plumbed water system impressively effective but flags a narrow vacuum roller, feeble side brush, and untested carpet-wetting. No whitelisted source measured cleaning performance for the S10. (1 sourced review.)
Praised: Plumbed-in dual-dock water station worked and looked impressively effective in a live demo; Self-refilling/self-emptying automation seen as an exciting, future-facing smart-home integration.
Flagged: Narrow anti-tangle vacuum roller and feeble side brush may limit thoroughness of the clean; Self-drying roller's claim of not wetting carpets was unverified by the tester; Requires retrofit plumbing connection and setup is not the slickest.
