Worse performance of the carpet mode function

VANT 509 4 0 

On latest fw i noticed worse performance of the carpet mode function. 
The vacuum cleaner start the maximum power after entering the carpet, but immediately back to notmal power, and again.....
On the previous fw, it worked correctly. 
I have short hair carpet.
Maybe a good solution would be to add sensitivity levels for this function? Something like wet mop levels.

    Hi, thanks for reaching out.


    Carpet boost mode means device will auto increase suction strength to max when it is on carpet to vacuum stuff better. The brush could recognize carpet by feeling its resistance increased, comparing to hardwood or tile. The suction strength will recover to normal on hard floor when resistance decreases.

    If the hair of main brush is worn, the carpet mode may not work any more as the robot could not feel resistance change.


    Please show us some pictures of the main brush. And you can send us a video of this abnormal behavior.


    Could you tell us where did you purchase the product?

    If it was from amazon, you could send us the amazon order number like 306-2905359-6881234.

    If it was not from amazon, you could send us product link and file or screenshot of receipt.

    Thanks for your reply.


    You can disable the carpet mode and change the cleaning mode to Max to give it a shot.

    If this issue still persists, you can hard reset it.

    Step 1. Hold the recharge button for 3-5 seconds.

    Step 2. Use a pin to press the reset button next to wifi LED just once，and power button, home button and spot cleaning button's light will be out. When you are doing this, please make sure home button is still under your finger's holding without moving.

    Step 3. Keep holding recharge button for 5 seconds after you press reset button until power button blinks again and you hear the tone "Restoring the initial version. It will take about five minutes. Please wait patient", and then you could remove the finger.


    Notice:

    1. Factory default restore will disconnect RoboVac from wifi. Please re-add it after factory default restore.

    2. Factory default restore will also make RoboVac's firmware version come back to original one when it was made in factory.

    3. Factory default restore will delete all your setting on device like scheduled cleaning.

    4. Factory default restore will delete every single cleaning's log including every cleaning's duration, size and map. But the total duration, total times of cleaning and total size will be still kept there.
