Make sure you have:
- set the profile of the housekeeper to enabled.
- set the availability of the housekeeper in their profile.
- allocated the housekeeper to the property.
- set the correct average housekeeping times in your unit types.
The system will try to auto-allocate the housekeeping tasks to your housekeepers based on the above, as well as check-in and check-out times, and travel time between properties to try and achieve the highest optimisation possible. You can override the allocation set by the system in Operations -> Housekeeping -> Upcoming Housekeeping Schedule
