Squeegee System

Functional Description

The squeegee suction hose draws air/water
from the squeegee assembly. The squeegee
consists of two squeegee blades: a forward,
notched blade, and a rear scraping blade.
The notched blade permits water to pass into
the space between the two blades, where it is
drawn into the suction hose.

Troubleshooting

Floor Streaks

Generally, floor streaks are caused by a problem with the squeegee. However, they can also be caused by
weak suction (see Weak Suction
• During normal operation, debris can get trapped under the squeegee blades. Periodically raise the
squeegee blade to clear debris.
• Clean and inspect the squeegee blades.
• If the streaks consistently appear at the center
or outside edges of the squeegee, check the
Squeegee Trim Adjustment
58.
• If streaks are consistently occurring at specific
locations on the squeegee blade, check to make
sure the blade is flat and without waves (N).
• If the waves (N) keep reappearing after being
corrected, it is an indication that the retaining
strap (I) is not tightened enough to hold the
squeegee blade from slipping.
