Product placement
(a) Shark Navigator Lift-Away Deluxe: its interface is operated (dust cup removed), its suction power is demonstrated, and its features are explained. This is the subject of the video. (b) TikTok Shop: appears as a marketplace/platform for the purchase. Removing the Shark vacuum would remove the entire point of the video; removing the mention of TikTok Shop would change the purchasing advice but not the product demonstration.
