In the '90s Electrolux Corp. experimented with different sales lines besides its door-to-door one. Going by memory, they were premium store, catalog, QVC, and fair/trade show. I'm guessing that the Xtreme and Xtreme Plus were sold through one of the indirect lines as household cleaners.

Just skimmed the XP manual and didn't see the word 'commercial' used at all. Interestingly, though, the illustrations showed a 3-prong plug, and the warranty for the motors and belt was 2 years--which was standard for commercial cleaners (standard household ones were typically covered for 5 years since the Super J. I know more recent ones such as the Lux Guardian Ultra & Lux Guardian Platinum were longer still.
