Prepare before first use: After unpacking, let the mop head fully expand for absorption. Airdry for 1–2 days or use a blow dryer to fluff it up, then attach to the mop base. Secure fit and improved reach: The replacement head uses a special triangular design that locks tightly to the mop base and resists falling off. It swivels 180° so you can clean along edges and into tight, sanitary dead corners without bending or crouching. Easy care: These replacement heads are machine washable — simply launder and dry in the washing machine for quick reuse. This reduces the need for handscrubbing and keeps maintenance simple. Versatile cleaning performance: Designed for sealed hard floors such as wood, tile, laminate and marble. Also suitable for tasks like car washing and glass cleaning. Compatibility and function: Intended as a spin mop replacement head that fits the corresponding mop base and rotation mechanism. Triangular shape and 180° rotation improve contact with floor surfaces and access under furniture or along baseboards. Practical use scenarios: 1) Kitchen spills and daily floor care: Quickly pick up liquids and dust from tile or laminate without frequent head changes. 2) Under and behind furniture: Rotate the head into corners and lowclearance areas to clean without bending. 3) Car or window washing: Use the same head to gently wash vehicle surfaces or glass for streak results. Care tips: Allow full expansion before first use for maximum absorbency. Machine wash and tumble dry or airdry between uses to maintain performance.
