Today I finally got my Dyson V15 Detect. I ordered a week ago on the Dyson site and even received a present, free parts and a storage bag for the Dyson V15.
The Dyson V15 is a new design. A laser reveals microscopic dust. This new technique is called "Laser Dust Technology". This new technology is aimed at people who are having problems finding dust in their homes.
The Dyson V15 is the most powerful, intelligent cordless vacuum¹ with a laser that reveals microscopic dust. Even when you don't see any dust in your home, this vacuum cleaner will find the dust for you. Engineered for whole-home, deep cleaning it has suction power, run time and tools designed to deep clean your whole home. In Auto mode the Dyson V15 Detect intelligently optimizes suction and run time based on dust level and floor type. A piezo sensor and Dyson DLS™ technology automatically sense debris level and floor type to adapt suction for the right balance of power and run time when you need it. The Laser Slim Fluffy™ cleaner head reveals hidden dust on hard floors and the High torque cleaner head with anti-tangle comb adapts to all floor types. The Dyson V15 Detect calculates and categorizes picked-up particles, showing you on-screen as you clean. It also, displays run time countdown, power mode, and maintenance alerts.
