Unlike upright vacuums with HEPA filtration, most robot vacuums have basic filtration that captures large particles but exhausts fine PM2.5 and allergens back into room air. Lithium-ion batteries pose fire risk if damaged or improperly disposed. Sweeping action resuspends settled floor dust into the breathing zone.","synthesis":{"derived_risk_level":"extreme","synthesis_confidence":0.744,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.265,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
