Likely need to return it, the spinning nature of the mop head is prone to such failures. I'd take a soft wire brush or tooth brush to the fittings before as a last ditch effort.

Hi,

We apologize for any inconvenience caused.Please follow these steps to try and resolve the issue:

1. **Check Mop Pad Holder Installation:**- Ensure the mop pad holder was not installed while the robot was turned off. It is recommended to install the mop pad holder after turning on the robot, as it may not attach magnetically otherwise.

2. **Preventing Mop Pad Holder from Falling:**- When the robot climbs over carpets, thresholds, or small steps, the mop pad holder may get stuck and fall. Set up a mopping restricted area to prevent the robot from entering such areas with the mop pad holder.- Tidy up any power cords on the floor before cleaning to prevent the mop pad holder from falling due to entanglement.

3. **Check Magnetic Attraction:**- Manually install the mop pad holder to ensure it attaches magnetically.

4. **Restart the Robot:**- Restart the robot and try the installation again.If the problem persists, please feel free to contact us(support.na@dreame.tech) again. Thank you for your understanding.

The mop pads holders that are actually attached to the vacuum are fine.. its the mop pads that keep coming off of the holder...like the velcro that holds them on isn't good.

Im having this same issue.  The mop pads keep wrinkling when it goes home or washes the pads.  I've bought replacements thinking that was my issue as well but the new ones did the same

I am having the same issue on a brand new machine after two weeks. Customer service isn’t helping. Just want a refund.

The Velcro that the mops attach to is what has failed.  You need the new mop disks.  I had to get new ones too.
