Machines with a load sensor can weigh the load and adjust settings accordingly. This means you don't have to feel as guilty about doing a smaller load as the machine will use less water.

2. maximum spin speed
A faster spin speed means you can get things cleaner with a lower temperature of water. Using a fast spin also extracts water, meaning that the clothes come out nearly dry. Generally, anything over 1000 rpm is very good.
Asko W6884ECO: 1800rpm
3. has top energy efficiency rating
The appliance is either Energy Star Certified, or has an EU energy efficiency rating of A++ or A+++. This means it consumes around 20-30% less energy than is required by the minimum local standards for energy efficiency.

Hoover OPH 716DF: 60mm
9. laundry capacity
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.
Samsung WF405ATPASU: 17kg
10. drum volume
With a bigger drum you can fit in larger items such as duvets, or do a big load at once.

11. front loading machine
Front loading machines are good as you can use the space above and sometimes stack a dryer on top. In general front loading machines use less energy, using less water by only partly filling the drum and obtaining higher spin speeds which clean without requiring as much heat.
