IPX Water Ratings: Enclosure Protection and Scope

The water digit identifies a defined enclosure test category rather than a general promise of waterproof use. IPX4 concerns splashing water, while IPX7 concerns temporary immersion under its specified conditions. These are different tests, and a higher number should not be read as permission for every pressure, temperature or cleaning method. An immersion marking does not automatically establish resistance to a high-pressure jet or detergent. The X indicates that a solid-object protection digit is not specified in that marking; it does not mean that the product has passed every dust test. The current catalog does not publish a model-level IPX rating or a matching enclosure test report, so no product receives an inferred rating here.

Washable heads do not establish water protection for the complete powered enclosure. T1 publishes four removable silicone massage heads, and its features describe those heads as washable. That is a component-care statement. The same current record does not publish a complete-device IPX rating, charging-port protection or an immersion test. Water entering a powered housing is a different question from cleaning a detached contact part. The distinction is particularly useful for scalp-category merchandising, where photographs near a bathroom can create an unintended wet-use impression. A retailer can describe the removable heads within the documented scope without adding shower-safe, submersible or dishwasher-safe wording. Care methods, reassembly and operation follow the product's supplied instructions.
