indicates that removal of a guests dust varies according to its state: being
vacant, occupied or out of order .If the guests room is vacant the housekeepers
remove dust at a percentage of 3%.If it is occupied ,and there are guests using it
,removal of dust occurs at a percentage of 55%.If the room is out of order , the dust
removal occurs at a percentage of 42%.The ideal procedure is that room dust should
be removed 100% regardless of the rooms condition: vacant ,occupied or out of
order. If not cleaned ,dust may accumulate in the room and help breed harmful
insects and cause polluted air which might cause disease.
