Your sweeper will be scheduled for a day and time at your request. If your job is scheduled as the first of the day, the sweeper will arrive within five minutes of the scheduled time. If your job is scheduled later in the day, these times are more flexible. The sweeper’s arrival time is dependent upon the day’s earlier jobs. For jobs other than the first of the day, it is possible that the sweeper might arrive earlier or later than the estimated time but we always do our best to arrive on time. Some jobs might take more time than originally scheduled because it’s extremely important to us that each and every client receives the best possible service.
