Back near the end of April Mikey noted his Shark Navigator died after 3 months of abuse.
The Shark Navigator took a dump.
3 months of solid use killed the brush/roller motor.
I got my freebie from BBB so in another 3 months I'll try that Sanitaire.
Seems like they've wet the appetite with the lower priced model and are bumping them up to a slightly bigger, better one... and slightly more expensive too. Excellent marketing. Nice picture of the lady vacuuming her filthy hardwood floors with a subliminal "S" left behind... nice touch.
