The Dyson V15 Detect (SV45) is a powerful cordless stick vacuum designed for intelligent, whole-home deep cleaning. It is most famous for its Fluffy Optic™ cleaner head, which uses a precisely angled beam of light to reveal microscopic dust on hard floors that is otherwise invisible. The machine features a Piezo sensor that continuously sizes and counts dust particles, automatically increasing suction power when it detects higher volumes of debris. With its Dyson Hyperdymium™ motor spinning at up to 125,000rpm, it delivers 230AW to 240AW of suction, making it one of the most capable cordless models for both carpets and hard surfaces.
