😓Reason #1: DWT May Be Blocked/Full

Dwt may be Blocked or Full

When your vacuum cleaner’s dirty water tank (DWT) is full or blocked, it will reduce the suction power of the Tineco iFloor 3.

It mostly happens due to no maintenance or irregular cleaning. To fix this issue, clean the DWT of your Tineco iFloor vacuum cleaner and remove clogs from the inlet. 

Follow these steps:

🤔How To Fix 

  • Turn off the Tineco iFloor 3 and unplug it from the power source. 
  • Remove the dirty water tank and empty it.
  • Rinse the dirty tank with running water to remove dirt or debris. Use the 3-in-one cleaning tool provided by Tineco. 
  • Check the dirty water tank inlet for clogs and remove them with a small brush or a toothbrush.
  • Ensure the clean and empty dirty water tank of the Tineco iFloor vacuum cleaner is installed correctly.

🤐Reason #2: The Brush Roller Has Debris

If the brush roller of your Tineco iFloor 3 vacuum cleaner is clogged with hair or debris, it can lose suction power. Unfortunately, this is a common issue, especially in households with pets or people with long hair. 

To fix this issue, you can follow these steps:

🤔How To Fix 

  • Turn off the Tineco iFloor 3 and unplug it from the power source.
  • Remove the brush roller cover by pressing the release button and pulling it off.

  • Wash the Tineco iFloor brush roller cover under running water. 
  • Wash the brush roller cover in warm water with mild detergent to remove any remaining hair or debris.

🤮Reason #3: The Pre-Filter Is Dirty

Hepa filter is dirty

The pre-filter is an essential component of the Tineco iFloor 3 that helps to trap dust, dirt, and other small particles from the air.

Over time, the prefilter can become dirty and clogged, reducing the vacuum’s suction power. If you are experiencing a loss of suction power in your Tineco iFloor 3 vacuum cleaner, it may be time to clean or replace the pre-filter.

Follow these steps to fix this issue: 

🤔How To Fix 

  • Turn off the Tineco iFloor 3 and unplug it from the power source.
  • Remove the HEPA filter from the vacuum cleaner. Unclog the brush chamber with a fine needle carefully. 
  • Rinse the HEPA filter with cold water and let it air dry for at least 24 hours.
  • Ensure the clean and dry HEPA filter is installed correctly in the Tineco iFloor 3 vacuum cleaner.

🤢Reason #4: Motor Air Inlet is clogged

If your Tineco iFloor 3 vacuum cleaner is shutting off or losing suction power, it could be due to a clogged motor air inlet.

The motor air inlet is where the vacuum draws in air to power the motor, and any blockages can prevent proper airflow and cause the vacuum cleaner to shut off or lose suction power.

To fix this issue, follow the steps:

🤔How To Fix 

  • Turn off the Tineco iFloor 3 and unplug it from the power source.
  • Use a screwdriver or brush to remove the blockages from the motor air inlet of the vacuum cleaner. 
  • Reinstall the cleaned motor air inlet correctly. 


Do not let water or any foreign liquid enter the motor or the battery of the vacuum cleaner.

🤯Reason #5: DWT/Brush Roll Cover Is Incorrectly Installed

Dwt Brush roll cover is incorrectly installed

If you’re experiencing suction power issues with your vacuum cleaner, one possible cause could be that the DWT (dirt, dust, and debris container) or brush roll cover is not installed correctly.

The good news is that this is a relatively easy fix and can be done in a few simple steps. Here’s how:

🤔How To Fix 

  • Turn off and unplug your Tineco iFloor 3 vacuum cleaner to avoid any risk of electric shock.
  • Locate the DWT and brush roll cover. The DWT is usually located at the bottom or rear of the vacuum cleaner. It is connected to the debris channel to trap and hold all the suctioned dirt.
  • Check the DWT and brush roll cover. Carefully inspect the DWT and brush roll cover to ensure they are installed correctly. Look for signs of blockages, damage, or wear and tear, like cracks or chips, which may be causing the issue.
  • Reinstall the DWT and brush roll cover. If you find that the DWT or brush roll cover is not installed correctly, remove and reinstall them until they’re installed properly. 


Remember to charge your Tineco iFloor vacuum’s battery regularly before use to retain its battery life and proper performance. If the same issue persists even after trying all the steps mentioned above, contact Tineco customer support or avail of the warranty.
