The SpeedScrub SS 17-20 Floor Scrubbing machine gathers very little solution in the collection chamber. Also, it leaves enough solution behind that these dry into visible dirty streaks. These may be two issues which need checked:
1. Clog or other issue effecting suction system
2. Worn squeegee allowing streaks.
If 1. doesn’t resolve problem and new squeegee is ordered, component information should be added to the KB page.
