Bubble wash
Machines with this technology create small air bubbles in the drum during washing. According to the manufacturers, this significantly increases the efficiency of washing, including old dirt, and at the same time reduces friction both between laundry and between laundry and the drum, which ensures better preservation of delicate fabrics. In some models of machines, during
an air-bubble wash, the drum may not rotate at all. Technically, in machines with this function, it is possible to wash without the use of powder at all. However, the effectiveness of such washing, of course, will be lower. Note that soft water is needed for air-bubble washing — bubbles form difficult in hard water, and the effect drops.
Leak protection
An automatic safety system that controls the integrity of the system for supplying and draining water to the washing machine and stops the water supply in the event of a leak. The protection can be installed on the hoses, on the body, or both (full protection).
Leak-proof hoses are equipped with special sensors and solenoid valves at both ends that shut off the water supply in the event of a breach in the hose. They can be used for both sampling and draining water. It is worth noting that for most washing machines, leak-proof hoses can be purchased separately, even if they are not included in the original package.
Protection of the body of the washing machine is carried out using sensors installed on the bottom of the device isolated from water. When water enters the bottom, its supply to the machine is turned off. The presence of leak protection allows you to avoid troubles like a short circuit or a flood in the house. However,
leak-proof machines are more expensive than conventional machines, all other things being equal.
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.
Country of origin
The country in which the washing machine was manufactured (according to the manufacturer's statement). Despite the fact that production facilities in
China are often used to assemble household appliances, specifically among washing machines there are many products assembled in Europe (
Germany,
Italy,
Poland,
Romania,
Slovakia,
Slovenia, Turkey) or in the post-Soviet space (
Belarus,
Russia,
Ukraine).
There are many stereotypes about how the build quality depends on the specific "homeland" of the device. However, most of them are not justified: the thoroughness of quality control does not depend directly on the location of production. And within individual brands, the situations in this regard can be completely opposite: relatively speaking, for one company, Polish-assembled machines can be considered more reliable than Romanian ones, and for another, vice versa. In addition, such information (about which plant a given brand has is better) often turns out to be unconfirmed rumours. In light of all this, it makes sense to pay attention to the country of production. Especially if you fundamentally want (or do
...not want) to support a certain state by purchasing products manufactured in it.
