LG washing machines like T80SKSF1Z, T80AJMB1Z, THD10NWM, etc. are suitable for washing blankets and bed sheets. A 7 kg drum can wash a double duvet, towels, and sheets for a small family. An 8 kg drum can wash a queen or a lightweight-size duvet. It is suitable for a medium size family. A 9 kg machine can wash a king-size duvet and is the best option for large families. You should also check the label of the duvet/blanket before tossing it in the washing machine. The fabric care label usually mentions if you can wash that particular duvet/blanket in the washing machine.
