1990 Singer (Sharp) Quantum 800 SSMC V935 Super Electronic Upright Vacuum Cleaner

This is quite the uncommon unit!
There was a canister version of this design sold alongside the uprights, and this upright was made by Sharp, hence the existence of vacuum cleaners that are labeled Sharp that look nearly identical.
As with all Sharp vacuum cleaners, this one cleans well and has stood the test of time.
It has a belt setup similar to an old Panasonic with a flat belt, a round belt, and a pulley.
This vacuum cleaner started quite the bidding war on eBay and sold for over $200, so I had something more desirable than I thought on my hands.

A oddball singer that I want so bad. The upright and the Samsung made Canister.

This looks like a competitor to Panasonic's 6200 series Jet Flo, and they're quite uncommon, more so than the Twin Energy vacuums that came later. These also look to be way better built than the Twin Energy models as well.
