Need to clean kitchen, dining room, living room, 2 bedrooms, office and bathroom. Everything is on the first floor. May need deep cleaning the first time, then just maintenance after that. Cleaning products can be supplied. This would be for my 90-year-old mother, who is in great shape, but some things are getting more difficult for her to do herself. I'm thinking the first cleaning session may be a deep, heavy duty cleaning, and then just maintenance once or twice a month after that.
