A:Answer Hi there, this is Kelly with Dyson. Without knowing your exact older model Dyson, we cannot be 100% certain. However, there hasn't been too much redesign with upright/canister machine attachments in recent years, so you should be fine using the extra attachments you have purchased. Feel free to contact us at askdysonUS@dyson.com for confirmation.
Best wishes,
Kelly
