If the yellow caution tape is visible, it indicates that the tank is not correctly installed, which may result in low or no suction. ![SW DWT](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/SW%20DWT.png?width=121&height=216&name=SW%20DWT.png) ### Follow these steps if the *unit* has low/ no suction: **NOTE:** Once the dirty water tank gets filled, the automatic shut-off is engaged and suction is lost. 1. Turn your unit off and remove the dirty water tank. Release the tank lid and make sure is empty. 2. After emptying the dirty water tank, it is recommended to inspect the filter for any debris. ![Dirty tank 2-1](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Dirty%20tank%202-1.png?width=201&height=248&name=Dirty%20tank%202-1.png)![Dirty Tank 3](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Dirty%20Tank%203.png?width=425&height=217&name=Dirty%20Tank%203.png) 3. Once the tank and filter have been cleaned, remove the nozzle from the unit by pulling up on the latch and pulling forward.![The nozzle](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/The%20nozzle.png?width=392&height=233&name=The%20nozzle.png) 4. Check the suction opening and clear any clogs or debris. It is recommended to clean the nozzle to maintain optimal suction power. 5. To replace the nozzle, line up the two tabs on the base of the nozzle with those on the unit and rock the nozzle back into place. ![Nozz3](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Nozz3.png?width=180&height=222&name=Nozz3.png)![Nozz2](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Nozz2.png?width=184&height=222&name=Nozz2.png)![Nozz4](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Nozz4.png?width=180&height=222&name=Nozz4.png) 6. Ensure the empty dirty water tank is properly installed on the unit. There should be no gaps between the unit and the tanks. ![Dirty Tank 1](https://knowledgelibrary.ttifloorcare.com/hs-fs/hubfs/Dirty%20Tank%201.png?width=230&height=285&name=Dirty%20Tank%201.png)   **NOTE:** When the SmartWash is picked up or the ***Nozzle*** is not attached properly, it trips the ***Dirty Water Tank Float*** and stops the suction. Please reset the float by turning your unit off and emptying the dirty water, the float should go back to its normal position. --- ### If the *hose attachment* has low/ no suction 1. Remove the hose by pulling it away from the unit 2. Remove the attachment tool from the hose and clear out any debris. 3. Once both the hose and the attachment tool have been cleared of any debris, reattach them back together and plug the hose firmly into the unit. **CAUTION**: Do not pull the hose sideways or at an angle, it can cause the solution port to break. **TIP:** You can drop a coin through the hose to check for clogs, then use a non-sharp stick to rid                the hose of those clogs. **NOTE:** If you have tried to troubleshoot and need to fill a warranty claim, please visit our **[Warranty Information](https://hoover.com/pages/warranty-information)** page for more information on how to do so. ---   -
