our cleaner comes once a week for 4 hrs straight
she irons all my Dh's work shirts (between 4 and 8)
she washes the floors of 2 bathrooms, kitchen, living room and our bedroom (wooden). She vaccums these rooms plus the stairs (2 lots), hall, office, children's bedroom. she scrubs the shower, bath, 2 loos, 2 bathroom sinks, wipes mirrors, dusts furniture (does not move or tidy objects)
she changes the sheets on our bed (started when I was heavily preg and couldn't manage it)
she cleans the kitchen, scrubs the cooker, the sink, the table, the worksurfaces
and she'll do the odd thing if you ask, like clean out the fridge and wipe it down, or shake out rugs or clean cupboard shelves.
she has plenty of time to do this all in 4 hrs and takes personal calls and has a coffee with me and interacts with my children. She helps with the children in so much as picking one up if he or she cries when I'm dealing with the other one. AT first this freaked me out and now its great, and they like her a lot.
