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.
The more power per year a device consumes, the less energy efficient it is, making it more costly over time.

Dot matrix displays can show important text or graphics using a matrix of lights or mechanical indicators like the display on a calculator.
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.
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 lower noise level for washing you can worry less about disruption and may be able to do a wash at night or while reading.
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.
With an eco wash option, you can help the environment while saving on water heating costs. With this option, the machine utilizes cold water and a fast spin for effective cleaning.
