I find the idea more stressful than anything else. My mother had a cleaning lady twice while we were growing up and both times the cleaning lady caused problems (one was stuffing paper towels in the toilet and causing a flood!). My grandparents got cleaning help as they got older and the cleaning help always stole from them (including a USED lipstick – how gross).
You need to supervise them! So if I am going to supervise someone cleaning, I might as well do it myself.
So, my house is not as clean as some because no, I dont have time to clean under the beds too often. Thats ok with me.
