Gold Tested
Dyson rolled out firmware v3.2 for the V15 Detect, adding a new Auto+ mode that adjusts suction based on dust particle count in real time. We tested the update immediately — it extends runtime by up to 15% on carpeted homes.

We re-ran our standard vacuum test protocol with the new firmware. We measured suction power in Auto+ mode across three floor types and compared runtime to the previous Auto mode.
