Capacity
The maximum amount of dry laundry at which the washing machine provides normal washing quality and does not experience overload. For two people, a machine with a capacity of up to
5 kg is enough, for more — accordingly, more. The optimal value for families are
models for 6 and
7 kg. For large families,
washing machines for 8 kg,
9 kg and even
10+ kg will be appropriate. For small apartments, it is worth noting
narrow washing machines that have a depth of up to 40 cm, but at the same time capacity like in full-size machines.
Note that for different work programmes the allowable capacity can also be different. For example, for a quick wash, this number is most often noticeably less than the maximum stated in the specifications. These details should be specified in the instructions for the unit.
Water consumption per cycle
The volume of water used by the washing machine during a standard wash cycle. It is measured while washing the maximum amount of cotton underwear for this model with a normal programme and a temperature of 60 degrees.
When evaluating efficiency, one should consider not only the actual water consumption but also the maximum load. So, for example, a model with a load of 7 kg and a consumption of 49 litres per kilogram of laundry will be more economical than a model of 5 kg with a consumption of 40 litres: the first consumes 49/7 = 7 litres per 1 kg of laundry, the second 40/5 = 8 litres per kilogram. This moment is important, first of all, if a large amount of washing is expected.
Many modern automatic washing machines are equipped with intelligent systems that can adjust the water consumption to the actual load and avoid overspending.
Steam wash
A special washing mode. Instead of water, hot steam is supplied to the drum of the machine. Steam penetrates better between the fibres of the fabric, which makes washing more effective than washing with hot water. At the same time, due to the high temperature of the steam — above 100 degrees — the best antibacterial effect is achieved since water in the liquid state rarely heats up above 95 degrees in washing machines. In addition,
steam wash saves water and electricity, but such machines themselves are quite expensive.
Surge protection
Power surge protection automatically turns off the washing machine in case of power surges. It protects the device's electronic circuits from hazardous loads and prolongs their service life. In this case, the programme running at the time of shutdown is remembered. And when the power is restored washing cycle continues from the point at which it stopped.
Energy class
This parameter characterizes the efficiency of electricity consumption by the washing machine. Classes are designated in Latin letters from A to G, in ascending order of energy consumption. At the same time, in class
A there are subclasses "A+", "
A++ " and "A+++"; more pluses means less energy consumption, and the most economical option to date —
A +++ — outperforms class A by almost a third.
Machines of classes
A + and above are today considered economical, class A — medium, lower classes — high consumption. However, indicators below A are typical for semiautomatic low-cost models. As well as for units with dryers (see above) in which high energy consumption is simply inevitable.
Smartphone control
The ability to control the washing machine from a smartphone, tablet or other similar gadget. To do this, you need to install a special application on your gadget. In this case, the connection can be made via
Bluetooth or
Wi-Fi. The advantages and disadvantages of each method are obvious - the operating distance. So Wi-Fi allows you to control the device from anywhere in the world, while Bluetooth allows you to control it in close proximity. Control from a smartphone often turns out to be more convenient, understandable and intuitive to use than the unit’s own control panel. Another advantage is that the control gadget can receive various messages from the machine: about the start, end and overall progress of washing, about failures and malfunctions, etc.
Noise level (spin)
The maximum noise level produced by the machine during operation. Most often indicated for spinning — this is the noisiest mode of operation; for units without spinning (such as semiautomatic devices), this paragraph indicates the overall volume or the volume in the noisiest mode.
The
quieter the machine works, the more comfortable it is for others. This moment is especially critical if there are small children in the house. However, the decibel used to measure loudness is a non-linear unit, and the actual noise level is best estimated from comparative tables in special sources.
