I don't have a cleaner, but I am a cleaner.
I clean two bedroom homes in about two hours. A 3/4 bedroom home can be three hours. If a home had four bedrooms, three baths, a large kitchen, two receptions, and pets, I guess we'd be looking at four hours.
I do what the client wants me to do, but that's almost always:
Clean the kitchen exterior surfaces (plus inside microwave)
Clean the bathrooms, making everything lovely and shiney
Dust the rest of the house
Hoover the house
Damp-mop hard floors. High-traffic areas cleaned by hand (scrub brush, microfibre, whatever is appropriate to the type of floor.)
That's typical of regular cleaning. Some other things get done once in a while, such as cleaning the woodwork around doors or using a brush to get dust out of radiators. Furniture that can be moved without hurting my back or scratching the floor will be moved for hoovering.
