Belt on a fan creates resistance and slows the motor down. If you disconnect the belt there's no resistance and the fan spins faster with no tension from the belt. The suction is greater with no belt. The hose creates a seal around the fan so it creates a seal preventing loss of suction. The fan running at high speed max efficiency. The hose doesn't loose suction providing excellent suction.
