sweeper unit. The broom rotates in a clockwise fashion when
viewed from the left side of the vehicle, and collected debris
is swept onto a conveyor belt for transfer to a hopper.
In recent times, the modern air sweepers appear to have
many advantages over mechanical broom sweepers for gener-
al sweeping use. One reason is that most mechanical sweepers
only give the illusion of leaving a clean pavement surface. Al-
though large debris is removed by mechanical broom sweep-
ers, they are virtually ineffective at removing particles 60
microns and smaller. Studies have even shown that from an
environmental standpoint mechanical broom sweepers may
actually have a negative effect on the amount of storm wa-
ter runoff pollution. This is because the action of the broom
tends to break larger particles down into smaller ones, creat-
ing more small-micron particles than there were to start with.
And, whenever debris pickup is via an elevator, rather than
involving any type of air/suction action, a large amount of
these small particles are left on the pavement’s surface.
Vacuum Sweepers
Typically, there is a suction inlet on one side of the sweeping
head, and then the ‘used’ air is constantly exhausted during
the sweeping process. Most vacuum sweepers do not have an

air blast that transfers to the vacuum opening. Instead, they
employ some type of broom system to brush debris toward
the vacuum opening in the head.
Part of the impetus for the advent of vacuum sweepers was
that the majority of debris, especially the heavy debris, col-
lected within 36 inches of the curb line. Vacuum sweepers are
designed to do an effective job of cleaning within that area.
They may well be the current top choice for ‘storm water
runoff abatement sweeping,’ in areas where the majority of
the debris is within 36” of the curbline.
