[L40 Ultra] Dust bag box is very stinky

I bought this robot about a month ago. Despite all those problems I have encountered, it roughly works and I don’t have high expectations because it’s just a machine. But the new problem is really seriously bad. Days ago I used an automatic cleaning mode that stupidly chose “ mopping while vacuuming “ and I believe it caused the disaster.  I found the machine is very stinky, specially the dust bag box. It must be the mopping while vacuuming method made the dust bag wet. Then it becomes stinky. I have thrown the bag away, totally cleaned up every part from the robot to the base including the dust bag box and dried them. An hour later, I opened the box that holding a new unused dust bag and it’s as stinky as there were a rotten mice. I took the bag out and put some napkins in. Half hour later the napkins are very stinky too. Anybody know how to fix this? Thank you

Forgot to mention that the dust bag was  found wet and very noticeable amount of water in the box. I think the dust bag is designed stay dry.

Hi,

Is the odor coming from the base station? If so, clean the wastewater tank and the base station floor.

Is the dust bag wet?

Considering the dust bag was dumped and the odor is still there, I think the stinky smell comes from the dust collection pipe because it’s quite noticeable when the robot empty the dust.
