We have a Kenmore (I think it's actually a Whirlpool) front loader. We do whites, light darks, and dark darks separately. 2 adults, a baby, and a toddler, whites once a week and the others 2 times. We use All or Tide "free" stuff labelled as appropriate for use with front loaders, in a huge container from Costco. The whites also get bleach. It's comical how little detergent you're actually supposed to use, about 1/2" worth in the provided cup. Lasts forever even doing 5+ loads per week.
Our laundry machines are located on the same floor as the bedrooms, love it that way. No trudging up and down to the basement.
