If you’re looking for a more formal or elegant way to refer to a cleaning lady, here are a few options that sound more professional and refined…

• Housekeeper
• Cleaning Specialist
• Residential Caretaker
• Sanitation Expert
• Facility Maintenance Professional
• Cleaning Technician
• Domestic Assistant
• Custodial Manager (for higher-level roles)
• Environmental Services Coordinator (common in hospitals or large facilities)
• Household Manager (if duties extend beyond cleaning)

These alternatives convey the same idea but in a more polished or professional way, and some may reflect a broader range of duties beyond just cleaning.
