Requirement of entryway system

I am currently working on a residential building. For LEED V2009, the requirement of the permanent entryway system should have 3m long in the primary direction of travel. Also, pedimat must comprise at least 1 metre (3 feet) of the 3 metre (10 feet) requirement. Roll-out mats are acceptable for the remainder of the length only when maintained on a weekly basis by a contracted service. However, the "credit language" only mentioned “Acceptable entryway systems include permanently installed grates, grill s and slotted systems that allow for cleaning underneath. Roll-out mats are acceptable only when maintained on a weekly basis by a contracted service organization.” So, is it indicates that the project can employ Roll-Out mat only if the Roll-Out mat maintained weekly?
