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.
A hot water connection means that you can provide the machine with hot water from your main hot water supply. This can be faster than an internal heater and can save money if you have a cheap and efficient water heater.
The more power per year a device consumes, the less energy efficient it is, making it more costly over time.
A direct drive motor has no belt and pulley. This means it wastes less power in friction, are less prone to breakdowns and have longer lifetimes in general. They are able to operate more quietly and with less vibration.
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.
With a transparent door you can look inside the machine and see what laundry is inside.
Dot matrix displays can show important text or graphics using a matrix of lights or mechanical indicators like the display on a calculator.
The slightly sculptured surface structure of the honeycomb drum creates a thin film of water or air which gently cushions and protects your laundry.

A faster spin speed means you can get things cleaner with a lower temperature of the water. Using a fast spin also extracts water, meaning that the clothes come out nearly dry. Generally, anything over 1,000 rpm is very good.
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.
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.
During a spin, machines can get quite noisy. With less noise the machine is not as distracting and you won't be restricted to using it at certain times.
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.
The detergent drawer is washed automatically to prevent a build up of old detergent.
A child lock enables adults to prevent or restrict children’s use of the device.
