Strengths: The lighter weight made it so easy to maneuver around furniture & other obstacles, especially stairs! I had my own housecleaning company & the Oreck got the job done without my arms feeling like I'd just gone 10 rounds in the boxing ring.

Weaknesses: Didn't have any, as far as I experienced.

Strengths: Has great pick up, even 'pricks' up the nap of most carpet...takes ALL pet hair off furniture and carpet( so light, its EASY to pick up and run on sofas)

Weaknesses: no 'hand tools'....the high pitched noise, most pets dont like

What You Wanted to Know Before You Bought It: Has weakness for disconnects on switch to get loose..stick to OEM parts...found a cheaper agitator brush, but wore it out in a year...the genuine roller by Oreck is WOOD

What Would You Tell the Maker of This Tool: Quieter motor
