Our take on the LG WM3420CW 4.5 Cu. Ft. Smart Front Load Washer

The LG WM3420CW is a 4.5 cu. ft. front-load washer with a stainless steel drum, steam cleaning, and a 1300 rpm spin. It works with Google Assistant and Alexa, and it can be stacked with a matching dryer to save floor space. It sits in LG's mainstream line: it skips the TurboWash and auto-dispense features of the higher-end models but keeps the core wash programs and smart controls. Owners rate it well for cleaning and capacity, though some mention cycle length and vibration on spin.
