With an anti crease spin the machine gently rotates to shake out creases.
With a bigger drum you can fit in larger items such as duvets, or do a big load at once.
With a lower noise level for drying there is less disruption and you could use the dryer at night.
Vented dryers are cheaper and can be more efficient than condenser dryers. The damp air extracted travels through a long plastic hose and is discharged outside the home, either through a window or hole in the wall. You don't have to empty a water container like you do with some condenser dryers.
The machine will analyse how much heat is needed in order to dry each specific load, therefore increasing efficiency and saving energy.
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.
With a wider range of programs to choose from you can be more specific and choose the best, most economic program for your needs.
A two way tumbler spins in two directions. This is good for efficient drying and for untangling the load.
