The numerous shortcomings of the dustpan principle made an improvement inevitable. Thus, the roller throw principle – especially for larger sweepers – was developed to compensate for these difficulties.
Further development in the world of sweeper technology opened the gates to the future of efficient cleaning, but was far from the last word on the subject.
Front-mounted in the direction of travel, the brush rollers rotating counter-clockwise sweep the garbage, which has passed the rubber lip (problem area 1), via the head and into the rear-mounted dirt container. Therefore this is filled from above, which increases the effective usable volume significantly, but does not resolve all problems however.
As before, a rubber skirt is required in order to close the sweeping chamber forward and avoid garbage being ejected. Therefore the lighter parts such as in the roller dustpan principle are pushed in front of the rubber skirt and cannot be taken in by the sweeper.
If the roller brush has a reduced diameter due to wear, it no longer touches the brush tunnel in the upper right quarter, which makes the transportation of dirt impossible. The maximum size of the debris to be swept up is determined by a conflict of objectives:
On the one hand, the skirt requires some stability and therefore a low ceiling so that the dirt thrown against it does not exit out of the front of the machine again. On the other hand, a large ceiling for the rubber skirt is desirable so that larger particles may pass below it.
