The first improvement I experienced over my previous machine was how quiet this Samsung washing machine runs even when I'm running two loads at the same time. You see I'm able to run my wife's unmentionables in the top smaller washer,  with a full load of towels in the main front loader. Everything I have washed comes out so fresh and clean without looking beat up.
The top features of this machine are the optional steam clean and most of all would be the wifi connectivity where you get to choose how you want your clothes to be cleaned and monitor the time and progress your load is doing.
I would definitely recommend the Samsung washer to a friend because of how quiet it runs, dual washing, and its wifi connectivity that brings a boatload of features.
