Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Disappointing

I saw all the positive reviews on Amazon and picked this piece 'o junk up. Turns out it's just about useless. The brush has the torque of a clock's second hand - it literally stops as soon as you put any pressure on the carpet. The suction is pitiful and doesn't pick up what the crappy sprayer put down. It sits collecting dust in my basement.
