💡Tineco Keeps Saying Clean Dirty Water Tank FAQs

What does CWT empty mean on Tineco?

As mentioned, the Tineco vacuum has a dual tank system for separating clean and dirty water. 

CWT empty means you need to fill up the Tineco Clean Water Tank. An indicator light or a voice message will ask you to fill up the Clean Water Tank of the vacuum cleaner.

Why tineco keeps saying dirty water tanks are full?

Tineco keeps saying the Dirty Water tank is full when the air channel is clogged, or the dirty water tank has reached full capacity. 

Give your tineco vacuum cleaner a deep-cleaning cycle. Clean the brush roll, dirty water tank, filter, and floater of the vacuum cleaner.

Can you use a Tineco Floor without water?

Yes, you can do dry cleaning with tineco iFloor, but the results will be less satisfying. Using a water vacuum with a clean water solution sucks and traps the dust and debris inside the vacuum cleaner’s water tank. As a result, the dust can’t escape further into the house’s atmosphere. Thus, water cleaning is always better than dry cleaning.

How do I get my Tineco to self-clean?

To switch on the self-cleaning mode, follow the given steps.

1. Plug in the floor Washer and place it on the storage tray.
2. Dump the content of the dirty water tank into the shower drainage.
3. Fill 1/3 water in the clean water tank.
4. Switch on the Self-Cleaning Mode at the top of the handle. The brush roll and floor washer will start to move.
5. It will take approx 40 seconds to complete the self-cleaning cycle.
