Hi Pamela, it's Jack at Dyson.
Underneath the clear bin is the exhaust outlet, where clean, filtered air is returned to the room after passing through the machine. This is totally normal and part of the machine's design.
I hope this clears things up, but if you do have any further questions please email [email protected]
with your contact details, and one of our experts will be in touch as soon as possible. You can also find help online by visiting www.dyson.com/support
