We recently purchased a combination washer/dryer unit. We throw the dirty clothes every night before bed, set the timer (electricity prices here are lower over night), and the clothes are all washed, dried, and ready to be folded when we wake up in the morning. The only manual part of the process is folding/putting clothes away - but those tasks aren't really parallelizable anyway - so I fail to see how adding in a trip to a laundromat could yield better efficiencies. Admittedly we don't really bother to separate anything (everything gets cold water, dry on low heat) - so you may be getting better results than us. :)
