Real Customer Support Cases & Troubleshooting Guide
Maintenance & Common Problems & Solutions
Most customers contact us only after the machine stops working properly.
After handling a large number of support requests from different countries and working closely with customers through photos and videos, we noticed something consistent:
Most issues come from a few common and repeatable causes.
This page is a collection of real troubleshooting situations we’ve seen during after-sales support. It is not a technical manual. It is simply a set of practical notes that may help you identify the problem before replacing parts or stopping operation.

Real Customer Support Cases
Every machine tells a different story, but many problems turn out to have surprisingly simple solutions. Here are some of the support cases we’ve handled over the years. We’ll continue adding new ones as they come in.
Vacuum Motor Making Loud Noise
📷 Customer Photo
Machine: Ride-on Floor Scrubber
Reported issue: The vacuum motor suddenly became very noisy, and the machine was no longer picking up dirty water properly.
What we found:
Water had entered the vacuum motor. The customer used detergent in the solution tank without adding defoamer to the recovery tank. Excessive foam entered the vacuum system and caused damage to the motor.
Solution: Replaced the vacuum motor.
Prevention tip:
Always use low-foam neutral detergent and add proper defoamer to the recovery tank to prevent foam from entering the vacuum system.

Sweeper Stopped Working After Outdoor Storage
📷 Customer Photo
Machine: CYS140 Sweeper
Reported issue: The machine stopped working after being stored outdoors for a long period.
What we found: The machine had been exposed to rain and outdoor conditions for an extended time. Moisture entered the electrical system and damaged the control board.
Solution: We arranged an original replacement control board and shipped it to the customer by express delivery. After replacing the control board, the machine returned to normal operation.
Prevention tip:
Avoid leaving the machine outdoors for long periods. Store it in a dry and covered area to protect electrical components from moisture and weather damage.

No Filter Shaking Led to Poor Sweeping Performance
📷 Customer Photo
Machine: CYS175 Sweeper
Reported issue: The customer noticed the machine was collecting much less dust than before after long-term use.
What we found: The dust filter had not been cleaned or shaken for a long time. A large amount of dust, sand, and debris had built up inside the dust collection system, reducing cleaning performance.
Solution: We guided the customer through cleaning the dust collection system and removing the accumulated debris. After cleaning, the machine returned to normal sweeping performance.
Prevention tip:
Regularly activate the filter shaker and clean the dust collection system to prevent dust and sand from building up. Routine maintenance helps maintain strong sweeping performance and extends the service life of the filter.

Common Problems & How We Fix Them
Before You Start Troubleshooting
A floor scrubber is a combination of three main systems:
- Water system (clean water supply)
- Scrubbing system (brush or pad)
- Recovery system (suction and water pickup)
Most problems come from the recovery system, especially the squeegee and vacuum airflow.
In many cases, what looks like an electrical failure is actually a simple mechanical blockage or worn part.
When the Machine Won’t Start
This is one of the most common issues we receive.
Before assuming there is a major electrical fault, we usually ask customers to check a few basic points first.
1. Emergency Stop Button
Make sure the emergency stop is fully released.
A partially pressed emergency stop is one of the most common reasons the machine appears completely dead.

2. Battery Connection
Check whether the battery connector is loose.
During transport or long use, the connector may slightly loosen and interrupt power supply.

3. Main Fuse
If the fuse is blown, the control panel will not light up at all.

This often happens after voltage fluctuation or incorrect charging.

4. Battery Voltage
If the machine has not been used for a long time, the battery may be too low.
At this stage, measuring voltage is more useful than guessing.
Support Note
In many cases, what looks like a serious electrical issue is actually a simple connection or fuse problem. We rarely recommend replacing the battery first without checking these points.
When the Machine Leaves Water on the Floor
This is probably the most frequently reported issue.
Most customers tell us:
“The machine is working, but the floor is still wet after cleaning.”
When this happens, we usually check the recovery system first.
Step 1: Rear Squeegee
📷 Insert image: worn squeegee blade
If the rubber blade is worn, cracked, or uneven, it cannot fully contact the floor surface.
This is the most common cause.
Step 2: Vacuum Hose
📷 Insert image: blocked vacuum hose
Sometimes dust, paper, or plastic film blocks the airflow inside the hose.
The vacuum motor may still sound normal, but suction performance drops significantly.
Step 3: Recovery Tank
📷 Insert image: recovery tank float system
If the float inside the tank is stuck, the suction system may stop working properly.
Support Note
In most cases, we find that the vacuum motor itself is not the problem. The issue is usually airflow restriction or a worn squeegee blade.
When There Is No Water Coming Out
Some customers report that the machine is running normally, but no water is coming from the solution tank.
Before checking the pump, we usually start with the simplest point:
Water Filter Blockage
This is one of the most common causes. Over time, small particles can block water flow.
Cleaning or replacing the filter often restores normal operation immediately.
📷 Clean the clogged filter
Solenoid Valve
If the valve is stuck, water cannot pass through even if the pump is working.
Solution:
Unscrew the screws and clean the white pipe.
📷 Dual-coil solenoid valve
📷 Single-solenoid valve
Support Note
In many cases, the pump is still working normally. The blockage usually happens earlier in the water path.
When the Brush Is Not Spinning
If the machine is running but the brush does not rotate:
Check Belt or Coupling
📷 Insert image: broken belt
A loose or broken belt is a common cause, especially after long-term use.
Motor Protection
Sometimes the motor stops automatically due to overload protection.
Let the machine cool down and restart.
When the Machine Leaves Streaks
If the floor looks clean but there are streaks or lines:
The issue is usually not cleaning performance, but uneven water recovery.
Most of the time, this is related to:
- Worn squeegee edges
- Incorrect pressure adjustment
- Dirty blade surface

Maintenance & Parts Guide
Preventive Maintenance
Most problems can be avoided with simple regular checks.
Daily
- Empty recovery tank
- Clean squeegee
- Check water level
Weekly
- Inspect filter
- Check vacuum hose
- Clean brush
Monthly
- Check battery condition
- Inspect cables and connectors
Replacement Parts Guide
Some parts naturally wear over time.
Brush
Usually replaced after long-term use depending on floor condition.
Squeegee Blade
One of the most frequently replaced parts.
If streaks or water trails appear, check this first.
Filter
Should be cleaned regularly to avoid water blockage.
Battery
Performance decreases gradually over time.
Vacuum Hose
Should be checked regularly for cracks or blockage.
Frequently Asked Questions
Why does my machine leave water even after replacing the squeegee?
Check the vacuum hose and recovery tank before assuming the squeegee is the only issue.
Why does the brush stop after a few minutes?
This is often caused by overload protection or belt slippage.
Why is there no suction even though the motor is running?
Airflow blockage is more common than motor failure.
Why does the battery run out quickly?
Battery aging or incomplete charging cycle is usually the reason.
Why is water not coming out even when the tank is full?
Check filter and solenoid valve first.

Closing Note
Most floor scrubber problems are easier to solve than they first appear.
In many cases, the issue is not a major component failure, but a small part that has worn out or become blocked over time.
