What to know before buying

Listing details to confirm

The listing's area figures conflict: the title and feature text say 600 ft², while the technical details say 600 square_meters. The listing also describes 80 hours as continuous runtime without stating the operating settings, and its control details list app and touch while voice-assistant support appears only in feature text. Confirm room coverage, runtime conditions and smart-home compatibility for the selected listing before purchase. The claimed performance figures are not independently verified.
