Great customer service is the cleaning industry is, in general, similar to great customer service anywhere else. Employees should smile, make eye contact, and practice active listening (repeat what the client said, and ask questions to clarify). Clients need to feel heard and respected. 

Janitorial staff should be respectful to the clients. They should be responsive to what the client needs. Treat clients with dignity and empathy above all else, no matter how difficult the situation is. Tasks should be performed as requested by the client. Finally, treat the client's space or belongings with upmost care.
