DOUBLE SCRUBBING
Double scrubbing is the process of making two or more
passes over a heavily soiled area. The first pass is
made with the squeegee raised off the floor (Figure
37). This allows the solution to penetrate the soiled
area for an extended period (3-5 minutes). The second
pass is made with the squeegee lowered.
FOR SAFETY: When operating machine, wear
closed-toe, non-slip shoes and go slowly on
inclines and slippery surfaces.
FOR SAFETY: When operating machine, follow site
safety guidelines concerning wet floors.
1st pass - squeegee up 2nd pass - squeegee down

finish.
FOR SAFETY: When operating machine, the
machine may only be operated on gradients up to
2%.
3. Raise scrub head when approaching bumps such
as floor transitions and thresholds. If bump height
exceeds a half inch (1.27cm) remove scrub disks
from machine.
4. Reduce speed around turns, near crossings, and
approaching tight areas, etc.
5. Avoid bumping the machine into posts and walls.
6. Wipe squeegee blades with a cloth if blades leave
streaks.
7. Pour a recommended foam control solution into the
recovery tank if excessive foam appears.
ATTENTION: Foam buildup will not activate the
float shut-off screen, vacuum motor damage will
result.
8. Use the double scrubbing method for heavily soiled
areas. First scrub the area with the squeegee up,
let solution set for 3-5 minutes, then scrub the area
a second time with squeegee down.
