What kind of mop is best for stair cleaning?

Question

Currently we use an ordinary mop with long cotton strands, quite low cost. Would like to get faster, would a flat sponge mop work better? Or a flat cotton mop? Bearing in mind there are 20 stairways so need something quite durable. Speed, effectiveness, and duarability are important. The surfaces are hard like marble.

Any ideas on how to speed up?
