Stackable machines are ideal if you have limited space as you could stack a tumble dryer on top of a washing 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.
The device is designed a specific way so that it can be built into a cupboard.
Dot matrix displays can show important text or graphics using a matrix of lights or mechanical indicators like the display on a calculator.
With a transparent door you can look inside the machine and see what laundry is inside.
You can adjust the height of the machine which means that if the floor is uneven you can level it out.
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.
With a wider range of programs to choose from you can be more specific and choose the best, most economic program for your needs.
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.
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.
