Maybe this is an interesting problem for you to work on...I think Dyson made it a touch point. Sound. I spent $1,000 on my robot vacuum and I think it does good enough cleaning but I can't stand to run it because it runs for hours and makes a droning noise that drives me crazy.

Related, I spent $400 on a Dyson hair dryer for me wife only because it is so much more quiet. Maybe their is enough value add in less noise. I don't need it to be any more clean and I don't think I need any more automation.

They track Covid outbreaks this way. Seems like a smart alert and invasion of privacy simultaneously.

Along with a closing door, a nice loud exhaust fan is appreciated.
