A new product on the household appliances market was the release of washing machines with two loading hatches. The models have gained recognition and popularity due to their comfortable washing mode, saving resources and time. The undisputed product leaders are the TW7000WS two-drum washing machine from the famous brand LG Electronics and DUO from the Chinese manufacturer Haier. What are the advantages of multifunctional household laundry appliances?
Loading clothes into the lower drum
Features of the “smart” unit
In 2015, at the world exhibition in Berlin, the Chinese company Haier demonstrated a fundamentally new washing machine - DUO HW120-b1558.
Washing machine DUO HW120-b1558.
Structurally, two drums are located in the machine body, one above the other, and have different laundry capacities. Main characteristics of the model:
- Freestanding washing machine with two loading hatches.
- Intelligent touch control, LED display with backlight.
- Water consumption – 54 liters per wash, electricity consumption – 0.08 kWh/kg.
- The capacity of the lower loading drum is 8 kg, the upper one is 4 kg.
- Complete protection against leaks, against children, control of balance and foam level.
Two detergent dispensers
The Haier double-drum washing machine has several programs and washing modes, which allows you to care for delicate items, wash coarse fabrics, downy items, denim, children's, silk, sportswear, and perform a pre-wash. The DUO HW120-b1558 model has a delayed start timer of up to 24 hours and has a stain removal function. The washing machine user can independently select the washing temperature and drum spin mode - a maximum of 1500 rpm. The device weighs 116 kg with dimensions of 128x60x60 cm. For equipment with two drums, the washing machine is considered compact, but requires a lot of free space for installation.
Features of the washing machine from Haier Duo
This smart gadget is a completely different unit from other washing machines. Yes, it has a number of features.
- The presence of 2 drums is the most important, distinctive feature of machines from Haier Duo, because all machines use only one loading tank.
- Touch screen. Thanks to this function, you can manage the wash without unnecessary movements. One press of a button is enough and the gadget starts working.
- Availability of device operation counters. Indicators placed on the drum doors allow you to track each stage of washing, which means you can know in advance when it is finished.
- Remote control. You can control the unit via a smartphone via WI-FI connection.
- A little noise from operation.
- Energy saving function. The machine from Haier Duo saves electricity and has a high level of performance.
- Large capacity. The lower drum can hold about 8 kilograms, and the upper one – 4.
- Compact as possible for such a device. The dimensions of the machine are 128x60x60 cm, which allows you to install it almost anywhere.
All these features once again prove that purchasing a device from Haier Duo is the best solution.
Advantages of the DUO model
The main and absolute advantage of a washing machine is the simultaneous washing of clothes from different fabrics in each drum. It is important to use a model from Haier for frequent washing.
When two drums are fully loaded, the total process time is halved. Advantages of the DUO HW120-b1558 model from Haier:
- Saving time and energy.
- Convenient touch control.
- Timers for counting down the washing process.
- Minimal noise during spinning.
- Energy saving function.
Since the two drums operate independently of each other, you can wash items in any loading chamber. It is convenient to wash delicate and capricious items in a smaller drum, and large, heavy items in a larger drum. The DUO two-drum model fully met consumer expectations in terms of functionality, has a wide range of capabilities and a variable set of options.
Disadvantages of a washing machine
Despite its versatility and omnivorous nature, the smart device from Haier Duo also has a number of disadvantages. For example, dimensions - despite its minimal size, the machine cannot be installed in a small room. The control unit is the same for both tanks: the machine has only one touch screen. If there is a breakdown or the slightest malfunction, washing will not be possible in any of the drums.
The disadvantages include the limited drying operation: the function of squeezing and drying clothes is located only in one of the drums. The cost of the unit is not affordable for everyone, and this is not surprising. At the moment, only wealthy people or those who live in Germany can buy a car.
However, all these shortcomings are insignificant and practically solvable. Thus, the inventors give a long service life of the machine - up to 10 years of continuous use. As for the cost, in a couple of years many people will be able to purchase such a machine.
Dual boot appliances from LG
LG Electronics, a well-known manufacturer of household appliances, presented its model of a washing machine with two loading drums, TW7000WS. The unit combines many useful functions and washing modes, and has an unusual design. The upper drum is angled for easy loading and holds 17 kg of laundry. The lower mini-drum LGI TW7000WS is located under the main one in a special drawer, allowing you to wash 3.5 kg of laundry.
Washing machine LG TW7000WS
The LG dual drum washing machine has the following features:
- Free-standing unit with touch control.
- Main drum LGI TW350W with steam function.
- 12 and 6 programs, including “no folds” option, timer mode.
Lower small drum
- Maximum spin speed – 1000 and 700 rpm.
- Selecting the temperature and setting the end time of the wash.
- Steam supply, extra rinse, cleaning function.
The lower drum is comfortable for washing delicate items and fine linen to give your items a fresh look. You can place outerwear, down products, blankets, and heavy textiles in the main loading hatch of the LGI. The choice of programs and the ability to set the washing temperature allows you to care for products made from various fabrics.
Which companies produce
In 2015, the world was rocked by a wave of serial production of washing machines equipped with an additional drum. The pioneers were such market giants as LG, Samsung and Haier - two South Korean and Chinese companies. Asia does not lose its leadership position, and therefore is ahead of the rest in terms of innovations.
On a note! The Asian company Daewoo presents a wide range of wall-mounted washing machines. But, unfortunately, I haven’t released the two-reel version yet.
In the domestic market, double drums are offered mainly by the two companies mentioned above: LG and Haier. If the country of origin is important to you, be interested in the place of assembly, because the first and second companies have branch plants in the Russian Federation. Thus, it is located in the Moscow region near Ruza, and Haier is based in the city of Naberezhnye Chelny. Unfortunately, domestically produced cars are sometimes inferior in quality even to their Chinese counterparts, so be careful.

Advantages of the model with the TWINWash option
The LGI washing machine with two drums is a leader among household appliances, since the total capacity of the unit is 20.5 kg. By running two wash cycles simultaneously, you can reduce wash time and reduce energy costs. The LG TW7000WS model is equipped with a direct drive inverter motor, which reduces vibration and noise levels.
Advantages of the TW7000WS/TW350W washing machine:
- Smart features and wash cycle tracking.
- During the washing process, you can add steam for heavy soiling.
- The "6 movements of care" technology selects a delicate stroke of the drum.
- LGI's intensive TurboWash mode leaves no traces of powder on clothes.
- The TW350W machine operates almost silently and washes things well.
The manufacturer LG Electronics guarantees 10 years of uninterrupted operation of the motor, which indicates a long service life of household appliances. The unit weighs almost 150 kg, which eliminates strong vibration of the device during the spin cycle.
Machines with two drums are an ideal solution for frequent washing and for large families. Combined with resource and time savings, consumers have the perfect technology for performing double wash cycles.
Washing machines with two drums: features and popular models
- Design features
- Principle of operation
- Advantages and disadvantages
- Model range of popular manufacturers
Washing machines with two drums are much less common than conventional models. But it’s difficult to immediately say whether they are good or not - for this you need to carefully study the features of the system. It is also worth paying attention to the specifics and capabilities of popular models.
Design features
The creators of household appliances seem to be trying in every possible way to “surprise” consumers with their developments. Another result of such efforts was the appearance of washing machines with two drums. The earliest companies to present such developments were concerns from South Korea.
In the domestic market, dual-loading machines are most often represented by LG and Haier. Interestingly, both companies have branches in our country.
Advanced models of this kind:
- equipped with touch screens;
- have special counters that track work as efficiently as possible;
- almost no noise.
But the most important specificity is how their work goes. In conventional machines, washing is carried out sequentially, from one stage to another, and this sequence cannot be disrupted. But in double-drum models, you can use one compartment for washing one item or bookmark, regardless of the other sector. The difference between these parts is usually due to the fact that they do not have the same capacity and performance. Experts believe that such a solution has very great prospects.
Principle of operation
A two-chamber washing machine, like a regular one, has a motor that spins the drum. And even the fact that there are not 1, but 2 reels, does not greatly affect the essence of the work. A heating element is installed in each compartment, which allows you to heat water autonomously and eliminate dependence on heating in one compartment. A huge role is played by the control unit, which now almost always operates on the basis of microcircuits and microchips. Without such a device, the automatic washing machine either stops completely or begins to operate intermittently.
Automation receives information from special sensors. The most commonly used sensors are:
- pressure switch (monitoring water flow);
- heating meter;
- drain indicator;
- tachometer;
- thermometer.
Users can obtain the necessary information through the display. Information about installed programs is also displayed there. In simpler washing machines, programmers are used, on which the current stage of the program is indicated by light indicators. Sometimes sound notification of events is used. Buttons and switches help you set the necessary parameters, and in advanced versions, touch screens.
In addition to the listed blocks, a dual-circuit washing machine will definitely have:
- water drain and inlet hoses;
- appropriate pumps;
- electrical cables providing communication between parts of the device;
- external door with a lock (located in the frontal plane or on top).
Advantages and disadvantages
Machines with 2 reels appeared relatively recently - they were first presented at the exhibition in 2015. But there are already a number of facts that allow us to judge the advantages and disadvantages of such technology. It provides an increased load volume compared to traditional models, and, importantly, it guarantees two washes at the same time. There is less hassle with sorting colored, black and white linen, and sorting by type of fabric. One of the tanks is provided by default for bulky items, and the other for relatively small items.
If you only need to wash a small number of things, this is also not a problem. You can load a smaller drum, thereby using the machine as efficiently as possible, also extending its overall life. Users note that modern two-chamber units perform their function very well. They will be able to remove even the most difficult stains in a short time. It is worth mentioning about saving water.
It is easy to understand that with this combination of properties, a device with two compartments is perfect for large families.
The disadvantages are less obvious, but they also exist. Thus, controlling both reels from one board increases the risk - if it fails, you will not be able to use the machine at all. If this is critical, it is better to immediately buy two separate devices. If you can save space using a two-chamber model, then only a little; it is more than two separate machines . Finally, the cost of such high-tech household equipment can be an unpleasant surprise.
