I have a good idea on these,
It's likely like this:
That bottom portion appears to come apart in 2, with the latch on the front. the motor is on the base, with the suction on one end, exhaust on the bottom (Hence, "Easy Glide"?). No wheels, "Glides" on carpet. the upper portion is nothing more than a cord rewind. the rest of the bottom shell's space is devoted to the bag (And, of course, the brush-roll).
I'm fairly sure that's how this cleaner functions.
