It was not entirely clear which Orek brush to order for my vacuum cleaner. I needed a more expensive one with a magnet. Cheaper wasn't right. You must check by model number before ordering. If you just pick and brush Orek, you'll see a cheaper option. I didn't see much of a difference between a cheaper brush and a more expensive one, other than a magnet. Not sure what value the magnet offers.
