  If your American-Lincoln Scrubber isn't picking up water well, several factors could be at play. Here's what to check: * Inspect the side or rear squeegee blades for wear or damage, and replace them if needed. * Examine the seal on the recovery tank for air leaks. * Flush the suction hose and pick-up tool to clear any clogs. * Ensure all hose connections are tight and undamaged. * Verify the hydraulic motor is working. * Clean the vacuum float cage. * Check the recovery tank for excessive solution or foam buildup, and consider changing the cleaning chemical mixture to an A-L approved material.

  If your American-Lincoln Scrubber isn't scrubbing effectively, consider these potential causes: 1. Inspect the scrubbing brushes for wear. Replace all three if they're worn to 1/2" (1.3cm) or less. 2. Review your scrubbing procedures, brush pressure, brush type, solution flow, and cleaning chemical. Double scrubbing might be needed for tough conditions. 3. Ensure you're using the correct cleaning agent or mixture, and that it's A-L recommended. 4. Clean the distribution tube and metering holes to the brushes. Also, check the feed hoses and valve and cable control system.
