Dyson's holiday promotions begin on Friday, November 21, and run through December 20, covering both Black Friday and Cyber Monday. Additional retailer-specific deals may start earlier or end sooner, but Dyson's own promo window typically stays consistent through that period.

Once the holiday window ends, major deals on Dyson items are few and far between.
