If your floor scrubber isn’t vacuuming up water, don’t panic — this is one of the most common issues with automatic scrubbers, and in most cases, it’s fixable with a quick inspection and a few simple steps.

At Wisconsin Scrub & Sweep, we repair and service all major brands of floor scrubbers — including Factory Cat, Kodiak, and more — and we’re here to help you troubleshoot the problem fast.

Here’s what to check if your scrubber is leaving streaks or puddles behind.

🔍 Step 1: Check the Squeegee Blades.

Worn or damaged squeegee blades are the #1 reason floor scrubbers fail to recover water. If the rubber is torn, warped, or coated in debris, it won’t make proper contact with the floor.

✅ Inspect both front and rear squeegee blades.

✅ Remove and rinse them thoroughly.

✅ Replace them if they show signs of wear or curling.

💡 Pro Tip: If your floors are uneven or textured, a worn squeegee blade will lose its seal faster.

🔌 Step 2: Make Sure the Vacuum Motor is Working.

If the vacuum motor isn’t running, your machine won’t be able to suction water into the recovery tank.

✅ Listen for the vacuum motor when you activate the suction.

✅ Check your control panel or settings to make sure it’s turned on.

✅ Inspect the circuit breaker or fuses if the vacuum is completely silent.

🧰 Step 3: Look for Clogs in the Recovery System.

Clogged hoses or debris blocking the suction path can prevent proper recovery, even if your motor is running.

✅ Check the vacuum hose for clogs, cracks, or disconnected fittings.

✅ Clear the recovery tank drain hose if it’s slow to empty.

✅ Empty and rinse your recovery tank — sludge buildup can interfere with suction.

🔋 Step 4: Inspect Battery Power.

Low battery voltage can cause the vacuum motor to run weakly or not at all.

✅ Confirm that your battery is fully charged.

✅ Look for any warning lights or fault codes on the display.

✅ If possible, test your battery with a voltmeter.

Weak batteries = weak vacuum performance. If you’re seeing this issue frequently, it might be time to service or replace the battery.
