Advance Floor Scrubber Troubleshooting Guide

advance floor scrubber troubleshooting

Advance floor scrubbers can handle big messes, but you can still encounter problems using them. These commercial cleaners clean large spaces in less time than other tools or even a team of cleaners. They dispense water from a clean tank to scrub the floor, then vacuum it dry using squeegees.

If you’re having trouble with your floor scrubber, you might want to know, “How do I fix my scrubbing machine?” This guide walks you through Advance floor scrubber troubleshooting.

Most Common Advance Floor Scrubber Problems & How To Solve

Because floor scrubbers combine a mop, scrub brush, and wet and dry vacuum into one appliance, many moving parts could malfunction. They use batteries to propel all the necessary components, so that’s another area that could cause problems.

These troubleshooting tips give you information on how to try and fix your Advance floor scrubber without needing repair service. The advice also works with other brands of commercial floor cleaners. For example, you can try these solutions for Global Industrial floor scrubber troubleshooting.

1. Poor Water Pick Up

If your floor scrubber leaves water behind, it’ll look like they didn’t clean the floor. The machines pick up the dirty water after scrubbing the floor. A device that’s not picking up water could have several potential causes.

Poor Water Pick Up

Possible Cause: Damaged or Worn Squeegee Blades

People who want to know, “How do you maintain a floor scrubber?” will appreciate information about the damaged or worn squeegee blades. Regarding Tennant T300 troubleshooting, checking the squeegee blades first can save you a lot of stress. These parts wear out with use because they do so much work.

Before replacing worn squeegee blades, you can turn them over and use the other side. You can also clean them as part of your regular maintenance to keep them working for longer.

Possible Cause: Recovery Tank Is Full

The floor scrubber not picking up water could mean you have a full recovery tank. If you don’t regularly empty the recovery tank, the water has no place to go. The machine could pick up water but have to leave it on the ground since there’s nowhere to put it.

Possible Cause: Vacuum System

The vacuum pickup hose might get dislodged as you use the machine. If there’s no airflow in the device, it can’t suck up the water. The vacuum hose can also have leaks that prevent proper suction. The vacuum motor needs to attach to the recovery water tank, so check these connections.

Possible Cause: Full Debris Tray

You need to clean the debris tray after every use, or else there’s insufficient suction to pull up the dirty water. If you’re wondering, “How do you clean a scrubber?” it’s not that hard. Your owner’s manual will have instructions on cleaning each part. For the debris tray, remove it and dump the contents in the trash. Rinse it and let it air dry to ensure nothing is stuck inside.

2. Poor Scrubbing Results

The machine’s purpose is to clean the floor, so if you see poor scrubbing results, you might wonder if the appliance is any good. Many people search for Tennant T16 floor scrubber troubleshooting tips due to lackluster results.

Possible Cause: Wrong Pad Pressure Settings

The pad on your floor scrubber significantly affects how it cleans. Regardless of the default pad, you can change it to best suit your floor finish. The pressure changes how aggressively the pads clean the floor, so poor scrubbing might mean they’re too gentle.

Wrong Pad Pressure Settings

Possible Cause: Improper Chemical Usage

The pads work because of the chemicals the floor scrubber sprays with water. Poor scrubbing can happen when the chemical you’re using isn’t strong enough to clean the dirt and debris on the floor. You also need to find the right chemical for your floor type, and you’ll want something different for waxed surfaces compared to concrete.

3. Brush Deck Will Not Scrub

One Tennant T500 troubleshooting tip is that the battery controls the brush deck. If you’re running low on charge, the machine will cut out certain features to prioritize other types of cleaning. Regularly charging your battery ensures the brush desk will always work.

4. Not Releasing Water

If your Tennant floor scrubber is not putting out water, it might be an issue with the mechanical system that pumps out water. A small computer in the machine regulates how much water sprays onto the floor before adding chemicals. Routine maintenance can keep your cleaner’s computer working, so you don’t need Tennant T5 troubleshooting help.

Otherwise, you want to ensure there’s water in the tank. It sounds like a silly problem, but it’s easy to overlook if you’re not using the floor scrubber often.

Not Releasing Water

Possible Cause: Clogged Solution Tank Filter

After you empty the floor scrubber, you want to leave the tank lid open to let it air dry completely. While this practice keeps mold from growing, it can allow dirt and debris into the tank. Over time, the dirt can build up and clog the tank.

Even if the tank itself isn’t clogged, the filter might be. The filter in the solution line cleans the water before it sprays. As sediment builds up in the filters, it blocks the water flow. Cleaning them as part of your regular maintenance prevents this problem.

5. Will Not Turn On

One of the biggest problems for Advance floor scrubber troubleshooting is when the machine doesn’t turn on. The root of this problem is usually a faulty battery charger. An inconsistent voltage between battery and charger can prevent the batteries from getting the power they need. The best solution is to get a new charger.

6. Poor Run Time

When you’re ready to clean your floors, you want to turn on the machine and complete the job. If you’re unable to clean everything with one charge, you’re experiencing poor run time.

Poor Run Time

Possible Cause: Batteries Are Not Charged

The batteries are often overlooked with all the daily maintenance a floor scrubber needs to clean properly. Some batteries don’t need daily charging, but it’s good to check them at least once a week to ensure you have enough to do the job.

Possible Cause: Pad Pressure Is Too High

A high pad pressure requires more work from the machine. As a result, you might not be able to clean as much of the floor as usual, but you’ll apply more pressure to the area you cover, getting it cleaner than before. You can lessen the pad pressure to prevent this problem.

Possible Cause: Old Battery

Are you wondering, “How long do floor scrubber batteries last?” Thankfully, they last a long time, but they hold less charge the older they get. So if you’re getting poor run time compared to before, you can get a new battery to solve the problem.

7. Floor Scrubber Won’t Move

If the floor scrubber brush is not spinning or the machine doesn’t move at all, double-check that you charged the battery and cleaned all the parts. If you keep up with your regular maintenance, then the most likely problem is a faulty wire. You can find out how to fix it from the owner’s manual or send it away for repairs.

How Often Should Floor Scrubbers Be Recharged?

Checking your floor scrubber’s batteries should be part of your daily maintenance. You don’t want to try and clean your business only to find the machine won’t turn on. Charging them overnight will give you a full battery each day.

Lead acid batteries deplete rapidly, so if you use them for at least 20 minutes, you’ll want to charge them afterward. However, you can’t charge them more than once within 24 hours. Putting batteries on the charger when you clean the other parts of the machine will help you stick to a good routine, so your floor scrubber works properly.

You should check the charge status weekly so you’re not unprepared. Fortunately, there’s no harm in charging lithium-ion batteries when you have the chance, so it’s better to be safe than sorry.

Why Does the Floor Scrubber Leave Streaks?

The floor scrubber leaves streaks because it’s not clean. Daily maintenance keeps your machine in good shape and prevents streaks. After use, always rinse out both the clean and dirty water tanks. The filters, debris tray, and scrubbers all need a quick wash. Let these parts air dry.

Clean the pads and brushes and wipe down the underside of the lid. This step prevents dirt from returning to the clean parts after you wash them. As a result, your floor scrubber won’t leave streaks when you perform this daily maintenance. It’ll also keep you from having to send the machine out for costly repairs.


Many common floor scrubber problems are frustrating when you want to clean your business and move on. These Advance floor scrubber troubleshooting tips help you tackle any problem you’ll face with these machines. Keep your appliance in good shape so your company’s floors shine.
