Common Themes Across Home Appliances

Battery-powered appliances share the same fate: Lithium-ion degradation means cordless vacuums, like TWS earbuds, lose 40-60% capacity within 2 years.
Warranty as a revenue model: Premium appliance brands often structure warranty terms and replacement part pricing to make repair uneconomical vs. replacement.
After-sales service is the product: For appliances, the customer service experience IS the product experience. A broken vacuum with good support is less painful than a broken vacuum with denied warranty.

For Product Teams

Key Signals: The Dyson V15 case illustrates a pattern: premium-priced appliances with non-replaceable batteries create a "planned obsolescence" perception that is now being litigated. International competitors (Dreame, Roborock, Tineco) offer user-replaceable batteries at lower price points, changing consumer expectations globally.
