With a delay start option you can schedule the machine to begin at a later time. You can also set the machine to wash at night if your electricity is cheaper outside of peak times.
With a lower noise level for drying there is less disruption and you could use the dryer at night.
More weight capacity helps if you want to wash something heavy like curtains. A traditional household machine can hold around 6kg, so with a machine much bigger you may waste energy using it when only half full.
4.has anti crease setting
With an anti crease spin the machine gently rotates to shake out creases.
5.has a drying rack option
Some things are too delicate for mechanical drying, so with this shelf you can dry things like sports shoes.
6.has a temperature selector
You can select the temperature manually if you want more precision and override the preset programmes.
