Your dishwasher is a good way to clean many things you normally wouldn't get to. Examples: hairbrushes, sponges, plastic toys, dish drainers. More a listed here: http://www.goodhousekeeping.com/home/cleaning/tips/a21598/things-you-can-wash-in-dishwasher/
The other important development in the early 2000's was a switching of emphasis from merely cleaning to hygiene. This was prompted by some scientific studies that documented the rise of superbugs. So competent cleaners are now doing double duty: creating a clean appearance and healthy conditions for your home.
House cleaning had it's own professional organization starting in 2003, the Association of Residential Cleaning Professionals (changed two years later to Association of Residential Cleaning Services International). This has been a great source of information and training for myself. www.arcsi.org
In the 1980s, house cleaning companies proliferated around the country. And the industry professionalized. One of the key developments was the working out of efficient cleaning methods by Jeff Campbell and his Clean Team company in San Francisco which they turned into a very influential book, Speed Cleaning, in 1985. It has influenced my own cleaning methods.
