Manual sweeping removes large percentages of debris but in the process allow residual dust to become airborne usually settling where least wanted. The process also requires double handling as once a manageable quantity of debris has been assembled removal is still a manual and messy procedure. Productivity has and will remain a grey area in terms of projecting efficiencies as it is seldom constant with little guarantee of 99% removal of debris from given area. To quantify the cost of this process one needs to include all the costs including reliability , consumables and personal protection equipment in order to compare accurately with a mechanised operation.
Filtered dust control, up to 4 microns, ensures that the dust created by the rotating broom is removed during the process whereby ensuring collected and removal from the area being swept. Productivity and costs are directly related to quality, maintenance and operator skills. These aspects being controlled through choice and management. Based on various Tennant sweeper models, cost effectiveness is as economical as manual sweeping with the advantage being the enhanced results.
