This generic 35mm Floor Brush will fit the Hoover Duros and Maytag canisters in their S3590 series. It is 12" wide and 2.5" deep, having natural hair brush strips with long bristles along the front and back edges of the nozzle. Wheels on the sides between the brush strips carry the weight and downward pressure on the nozzle, allowing the bristles to glide on the floor without being flattened. Notches in the front brush strip allow dirt to easily enter the nozzle.
The wands and floor nozzles on the Hoover canisters this floor brush fits typically fit over the wand and have release buttons on them since they lock on. This nozzle simply friction fits over the wand without a locking device.
