As far as I know, they are almost the same except for the color , the accessory, and the price.
DC39 animal is in PURPLE while DC39 is in YELLOW.
And the DC39 animal comes with a mini turbine head for picking up pet hair from tight areas while DC39 doesn’t have this tool. And DC39 Animal is more expensive than DC39 Multi Floor canister vacuum.
Otherwise, they are the same.
Contact Dyson customer service to make sure if you want.
