what is the difference between the XV 11 and the XV 21
carol k. asked on Mar 24, 2013
The XV-21 is the pet and allergy model in the box you get the pet and allergy filter. The normal XV-11 does not include the pet filter/brushes. However you are in luck, because in this Groupon deal you get the XV-11 with the Pet and Allergy upgrade kit which includes the filter and the brush! So the XV-11 being sold on Groupon with the bundle feature is identical to the XV-21, the only difference is the XV-21 comes with the filter+brush in the retail box and the Goupon sale comes with the filter+brush in a bonus package included in the shipping box with the retail boxed XV-11.
