A:Answer Washer buying guides advise that to properly wash a queen-size comforter, you'll need a high-efficiency washing machine (no agitator) with 3.5 cubic feet or more, depending on its fluffy factor (it should fit snugly but without cramming). Jumping up to 5.2 cubic feet will let you wash a king-size comforter and the sheet set all in one load. Although the ENERGY STAR® Qualified LG 4.9 cu.ft. MEGA Capacity High Efficiency Top Load Washer, Model # WT5270CW does not have agitator, it does have an impeller which takes up less room than an agitator. It will handle some King Size Comforters depending on their fluffiness...^IFV
