We gave them their own code to the door so they clean when we are gone. One time while we were gone the code wouldn’t work, they came, couldn’t clean, and we paid them anyway. I view it as kinda a friendly check in on the house while we are gone and it’s nice to come home to a clean house. I always try to reschedule vs cancel so they still get paid and the house still gets cleaned.
ETA. We also paid during Covid and I think they’ve done better since. They come every other week.
