Why stair carpet is different from room carpet
Stair carpet takes pressure and friction at specific points: the edge of every tread and the walking line down the middle. Much of it is held by metal grippers or rods and wraps around the nosing, so it cannot be treated like a rug you lift and shake.
A staircase is also a safety area. Looseness, moisture or slipping is a direct risk for children and older people, so care here means cleanliness and safety together.
Check the fixing before any cleaning. Carpet that is not well secured should not be pulled or dragged while you clean.
