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.
Max. spin speed
Maximum drum rotation speed in spin mode. The higher it is, the more intense the spin. However, note that not all types of fabric normally tolerate high speeds — a speed
of 1000 rpm or more should be used only for especially durable fabrics, and delicate ones need to be wrung out at low speeds, so the best choice is a machine that allows you to choose the spin speed.
The maximum spin speed (
1200 rpm,
1400 rpm), in particular, determines its efficiency (see Spin class), but this parameter is not decisive — the duration of the spin cycle and the diameter of the drum also play an important role. Therefore, for machines with the same spin speed, their efficiency class may differ.
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.
Drying capacity
The maximum amount of laundry that can be loaded into the washer to dry.
For more information about this mode, see "Dryer". Here it is worth mentioning that the weight of dry laundry is indicated in the specifications, and the maximum load for this mode is usually 1.5 – 2 times lower than for washing — this is due to the peculiarities of the process. In other words, you should be prepared for the fact that after washing with a full or almost full capacity, you will have to dry the laundry in two stages. However, the need to completely dry so many things at a time arises relatively infrequently — in most cases, part of the laundry can be dried traditionally.
Inverter motor
Washing machine with an
inverter electric motor.
Such motors are also called brushless because they do not have commutator brushes. Thanks to this feature, the noise level, heating and wear are significantly reduced, which has a positive impact on efficiency, reliability and durability. In addition, the accuracy of rotation speed control is increased. The reverse side of the coin is the rather high price of such machines.
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.
Energy class (new)
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. This was originally conceived until more energy-efficient models pulled up to class A, which eventually received the marking A+, A++, and A+++. Further development of technology has made it possible to go even further, and in order not to produce pluses in energy efficiency labelling, in March 2021, manufacturers returned to the previous indices from G to A, where A is the most energy efficient washing machine. Accordingly, the 2021 models will have modern markings, while older models will be marked in the same way.
Noise class
This indicator allows customers to decipher the values of the noise level in decibels. It is marked, like other classes, in Latin letters, where A is the quietest class of washing machines.
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.
