Evidence ledger
This ledger explains the evidence boundaries for UK Shortlists robot-vacuum routes. It covers consumer route choice by layout, floor type, maintenance burden and automation caveats; it does not claim direct home testing or guaranteed cleaning outcomes.
Coverage is limited to existing shortlist routes. This ledger does not create routes, change product choices or change rankings.
Main route for broad robot-vacuum shortlisting before branching by budget, floor type, pet hair, mop use or dock automation.
Budget-first route where navigation limits, suction claims, app friction and consumables need careful checking.
Automation route for buyers prioritising lower day-to-day emptying burden and dock space fit.
Specialist route for pet-hair ownership caveats, brush maintenance and floor-mix trade-offs.
Micro-Proof signals are public-safe summaries of evidence support, freshness and caveats. For robot vacuums, treat a signal as route guidance only: it is not a home-test badge, cleaning guarantee, hygiene proof or live merchant-state check.
For claim boundaries across all clusters, use Claims We Do Not Make.
