How to choose the suitable robot vacuums? Self-empty station or big volume dustbin ?

Self-empty station robot vacuums or big volume dustbin / dust bag robot vacuums?

To free more time for the users, now have self-empty station of the robot vacuums, which the dust station can last about 2 months for the robot vacuums daily cleaning job, and then empty the dust station every 2 months, but the cost still keep high for such models. Now we develop a new model which have big volume dustbin, and can also use disposal dust bag, which can last about 30 days for the robot vacuums daily cleaning job, cost is half of the self-empty models, so which one will be better?

Let's collect some feedback from Amazon to check what we concerned mostly：

Self-empty station disadvantages：

1.high cost: product cost, transportation cost and storage cost are very high

2. loud noise，like jet

3. Secondary cleaning. Since station cannot effectively absorb hair, consumers need to clean the dustbin and station again.
