This is my first bought, brand new washer and dryer set. I have pets and a husband who gets super dirty at work. Though I wasn't needing the IQ or smart tech in my purchase it was a nice though for them to connect together and I not need to think about what setting to set the dryer to after each wash cycle. Even in just the wash, a decent amount of hair is removed from clothes and even after an hour or 2 of sitting in the washer sometimes, my clothes don't smell musty or gross like my last front load washer. I do keep it cracked when not in use to allow it to completely dry to prevent smells and I do the recommended tips for my machines.
