How Do We Refurbish a Floor Scrubber?
Last Updated: 07/31/2017
Buying a used, refurbished floor scrubber can feel a little bit like buying a used car. If you are going to invest in a used machine, you want to feel confident that you are making a good investment. We want to give you that confidence, so let us explain what we do to a floor scrubber when we refurbish it.

1) Unload/Inspect

For the used scrubbers that we purchase, their journey begins when they arrive at our warehouse in Vinton, Iowa. We remove the scrubber from the pallet and make sure it wasn't damaged during transit. Then, we unhook the battery cables and take out the batteries. The old batteries are set aside to be recycled. All of our scrubbers are sold with BRAND NEW BATTERIES. Then it's time for an inspection. One of our experienced technicians evaluates the machine. If it meets a list of requirements, it qualifies to be refurbished. If it doesn't, we use it for parts.

The point is, a scrubber that you as the customer would consider to be "JUNK," would be put into that same category during this step. We NEVER SELL YOU JUNK.

2) Time For a Bath

It isn't uncommon for people to neglect their scrubber. Dirt and wax build up over time on a machines components, so before we can make any necessary repairs or replacements, the scrubber needs a good bath! First, the tank is filled with water to check for leaks. If a leak is found, we try to repair it. If we can't repair it, that scrubber's journey ends.

After looking for leaks, all of the electrical components including the computer board, control panels, and the charger are removed. Then, the deck and squeegee bar are removed. They will be washed separately, because they usually need more TLC. To clean the machine itself a detergent and hot pressure washer are used. If a tank has lime buildup, an acid bath is used to remove it. Wax is usually a problem, so we work hard to get it all off by scraping or even using a torch to burn it off. The idea is to get everything as clean as possible so that the technicians can do their job at the next step.

3) Evaluation Part II

The scrubber is now clean, but is it complete? It is time for a second evaluation and technician does an even more detailed examination to see if the scrubber can be restored to its previous scrubber glory (if there is such a thing).

First, our technician checks the electrical components. He turns on the machine and asks himself:

- What is the condition of the transaxle? Do the wheels turn?
- Do the brushes turn?
- Does the controller (the computer that runs everything) function properly?
- What is the condition of the vac motor?
- Does the potentiometer work?

Next, he moves on to the mechanical parts of the machine:

- How are the castor wheels, the squeegee assembly, and the drive wheels? While one tech is focusing on the function of the machine, another one is working on step 4.

4) Evaluation Part III

While one technician focuses on the body, transaxle, and electrical aspects of the scrubber, another one is focused solely on the squeegee bar, the pad drive motor, the scrub head deck, and the charger.

First, he looks at the squeegee bar. The squeegee rubber is replaced as well as any little wheels it may need. Then he cleans it again, and may even repaint it if it needs it. Second, he checks the pad driver motors. They are carefully tested to make sure they function. If they don't meet our standard, they are taken apart. Any worn out parts are replaced with new ones. If the motor is beyond repair, he may use a motor from another machine that has already been restored or may just order a new one. Next, new skirts are installed on the scrub head deck. The tech checks the pad drivers and the pads themselves. He then cleans the deck AGAIN and may be repainted.

After these evaluations are done, the machine is reassembled and is ready to be tested. New batteries go in and the scrubber is used around the shop to see how it works. Our techs may make minor tweaks at this point to get it to perform exactly like they would want it to work if they were going to clean a floor. All of our technicians are currently, or have used scrubbers to clean floors professionally in the janitorial world, so believe us, they know what to look for! Once they are satisfied, the scrubber is ready for the next step in its journey.

5) Detailing

After the floor scrubber is CLEAN and COMPLETE, they are given some cosmetic attention. As we discussed earlier, most people don't give a lot of attention to how their scrubber looks, so this step is an important one. Our goal isn't to hide defects, mainly we try to enhance and restore. Okay.... maybe hide a little! A variety of chemical cleaners are used to tediously spot clean everything. Once clean, our detail man gives a new coat of paint to any parts that are lacking in that department. The last part of the machine that receives attention is the plastic body. This is where you really can see if a scrubber has been mistreated or neglected and our goal is to erase that. Using some pretty cool methods, scrapes, scratches and gouges are made to disappear and new decals are stuck on.

At this point, the floor scrubber works well, looks great, and even smells good. It is sent from the shop back to the warehouse where it will wait to be sold. But before it goes to its new home, there is one more step we take to ensure our customers get exactly what they pay for.

6) Final Testing

As you can see, our refurbishing process is very thorough. However, when a customer purchases one of our scrubbers we do one final test to MAKE SURE that nothing has changed from the time it left the shop and sat in the warehouse, to the day it goes home with its new owner.

One of the technicians goes to the warehouse and does a test scrub with the machine on the concrete floor. Using the scrubber on this rough surface is an excellent way to gauge the scrubbers performance. The test lasts 20 minutes.

Following that, another technician will test the machine AGAIN in order to get a fresh pair of eyes and ears on how well the scrubber does it's job. Once both techs are satisfied, the new batteries are fully charged with the charger that will go with the machine.

So there you have it, that is our process. We have put a lot of thought and energy into it so that we can have peace of mind, and so that our customers can as well.
