I wanted to post a video of the base unit when it empties the dust cup. I have also posted a video of the sound level when the mop head is cleaned. I think it's important to a lot of people to know how loud the unit is when it is doing its empty process. You'll be able to hear it on the video and then I explained a little bit but the base unit sits right up against the opposite side from my bed wall. I always run the unit at night when I go to bed. Typically I'm asleep by the time the unit has finished cleaning the floor and is ready to empty. I have not been awakened by the vacuum base emptying at all in the time I've had it. With that being said I've also used a mova P10 in the past that would sit in the same spot and it did not wake me either. I think that's a big attribute to mova and the product that they are putting out. I have had other brands of robotic vacuums and I would never have placed the base for the unit right on the opposite side of wall from where my head is sleeping.
