Once the upright vacuum is securely positioned, extend the vacuum's hose attachment. The video shows a person using what appears to be a small power brush or upholstery tool attached to the hose. Systematically vacuum each carpeted stair tread and riser. For effective allergen reduction, make slow, overlapping passes (at least two to three) over all carpeted surfaces. Pay special attention to the edges of the stairs, the corners, and the crease where the tread meets the riser, as these areas tend to accumulate a significant amount of pet dander, hair, and dust. The hose attachment allows for flexible movement and precision cleaning in tight spaces that the main vacuum head cannot reach. Work your way up or down the stairs, depending on the length of your hose and your preference, ensuring no carpeted area is missed.
