The X9 Pro has a dustbin capacity of 410ml, which is sufficient to clean the whole house once for most households. However, the actual frequency of cleaning the dustbin will depend on the size of the rooms in your home and whether you have pets. If you have a larger home or pets that shed a lot of hair, you may need to clean the dustbin more frequently. 

In addition, the eufy Clean app allows you to easily control and monitor the real-time cleaning process of the X9 Pro. The app also has a feature that reminds you to clean the dustbin after 10 hours of cleaning. According to our test data, this setting is a
recommended time to clean the dustbin, according to our test data. However, if you have a lot of debris or pet hair in your home, you may need to clean the dustbin more frequently than every 10 hours. If possible, you can clean the dustbin after each cleaning cycle. Below is a video link to show you how to clean it.
