As far as I know, there is no mechanical difference between Eureka AS1104A and AS1104AX. The AS1104A is a general version while the AS1104AX is a BestBuy exclusive version. I contacted Eureka customer support, they told me that the “AX” comes with an extra part, like an extra wand, or filter, or belt, etc. And I chatted with a BestBuy customer service person online, and the person I contacted told me that the AS1104AX comes with both a PET Power Paw and a stair and upholstery brush. These 2 tools are turbo driven upholstery nozzles, the PET Power Paw is built with pet in mind. It has Plastic Teeth to loose the hair and a rubber strip and bristles pick up the hair. It seems that the Stair & Upholstery Brush (part number 81295-2) does not have the plastic teeth and rubber strip. Product info on Eureka.com shows that the AS1104A only has the PET Power Paw. So, I think the AS1104AX comes with the extra upholstery nozzles – a Stair and Upholstery Brush.
These two both feature cord retractor, brush roller On/Off switch, manual pile height adjustment and HEPA charcoal filter for cleaner air.
