So many people talking like cleaning services don't exist
I've used on in the past, but I found that I was routinely dissatisfied with how they were doing things and I felt I needed to maintain a certain level of tidiness to allow them to clean properly. I think there is an intrinsic cost to having hired staff in one's home that most consumers would be factoring in, consciously or not.
Probably $80/day for someone to do everything I want done. 20 days a month.
$1,600/month.
It'd take two years, and the robot has paid for itself.
