Replacement Filter for Shark ION Robot Vacuum RV850 Series

Shark recommends replacing the ION Robot's filter about every 2 to 3 months with regular use. Reduced suction or a musty smell coming from the unit are both signs it's due sooner than that. This is a third-party compatible filter designed to fit the Shark ION RV850, RV851, and RV852 series robot vacuums — not an official Shark-branded filter. Always confirm your exact model number against the product listing before ordering, since Shark's robot vacuum lineup (ION, IQ, AI) uses different filter shapes across series. /out/page_art_781ac8a34f0d/B08LKNZ66B As an Amazon Associate, Replenish earns from qualifying purchases made through links on this page.
