Reliability! I no longer have to worry if my cleaning person will call in absent. I do a lot of event entertaining and when that would happen, I would have to squeeze in time to clean myself on top of the food purchasing and preparation. It is not ideal and now I no longer need to worry about this happening.
We recently sold our home after years of service and moved overseas. Not only did we voluntarily provide the new owner with Molly Maid info, The guy who we contracted to deep clean the carpets asked who did our final clean specifically. They did a way better gob than most companies he has come in after.
We both work full time and have kids. It is so nice coming home to a clean house. This takes a huge burden off of us. I am always impressed with the job that is done. Sometimes I almost walk into the shower door because it is so clean.
