I agree with you, I think 4 hours is pretty realistic. KK didn't have to do many tasks that cleaners typically do such as dust the baseboards, dust ceiling fans and light fixtures, dust blinds, make beds, scrub soap scum from shower walls, Scrub calcium deposits in toilets, clean burned on food in ovens, polish wood furniture, polish appliances, vacuum carpets, etc. She was only trying to get rid of all appearance of blood so that the house looked "normal". She pretty much only cleaned where she saw blood. And she missed spots in the bathroom which were seen by KB's family members. A professional cleaner would have wiped the outside of the toilet down-- that's pretty basic cleaning bathrooms 101. When there was blood on things she couldn't clean such as fabric on pillows, curtains, or toys she simply removed those items and threw them away in a trash bag. I think she threw away the bath mat too. She left several spots of blood that she was able to point out to LE later. If she had been cleaning as a paying job she would have been fired. She took short cuts that normal house cleaners wouldn't dream of doing. Between the short cuts, the poor cleaning job and the small size of the home I can easily see her getting it done in 3 or 4 hours. MOO.
