The Bosch Group was founded in 1886 as part of BSH Appliances, a joint venture with Siemens. BSH is the number one manufacturer of major appliances in Europe and the third largest in the world. In 2014, Bosch acquired a 50 percent stake in BSH and BSH became a wholly owned subsidiary of the Bosch Group.
 
Bosch washing machines are divided into 2 series, 4 series, 6 series, 8 series, and flagship imported models Zhen "quality" series, which basically correspond to the iQ100, iQ300, iQ500, iQ700 and iQ800 series of Siemens, the same brand of BSH, and are basically the same in terms of functions, key technologies and components.
 
Bosch front-loading washing machines have all adopted BLCD brushless DC motors with a 10-year warranty, which are not inferior to DD motors in terms of efficiency, driving performance, noise and vibration control. The limit dehydration speed of the 2 series, 4 series, 6 series and 8 series is 1000, 1200 and 1400 rpm respectively, and the imported model is 1600 rpm.
 
Most drum washing machines rely on the drum to rotate a few times, and the amount of clothing and water volume is judged by the motor weighing, and the water absorption of the clothes will seriously affect the measurement accuracy, and the control of the washing water volume is mostly sloppy. Almost all Bosch models are equipped with Precision Water Inlet Technology as standard, which uses a load sensor to determine the amount of laundry and finely adjusts the amount of water through a flow sensor to achieve higher energy efficiency and washing performance. Most models are equipped with electromagnetic straight-pull door locks, so you don't have to wait to add clothes halfway; BSH washing machines have unique ring-shaped water-rippled side panels, which are said to reduce vibration and noise. 2 series is an entry-level model, also known as the F12 series on the e-commerce platform, priced at about 3000 yuan, although the laundry program is less, but the functions of daily use are basically there, adding night washing, baby washing, down jacket washing function.
 
Compared with the 2 series, the performance of the 4 series motor has been improved, and the inner barrel has been upgraded to a more gentle water rhyme inner barrel, which supports more fabric washing programs, such as plush toys, jackets, etc., and has added professional sterilization liquid washing programs; The precision control water intake technology on the 2 Series has been upgraded to a smart sensing system that supports more sensors, which is the same as Siemens' iSensoric technology. The stiffeners of the outer barrel are placed externally, and the inner side becomes smooth and not easy to hide dirt and dirt, and the hygiene is greatly improved, and the price is also about 3000 to 4000 yuan, which is more worth buying than the 2 series.
 
The 6 series motor has been upgraded to 1400 rpm, and the counterweight of the whole machine has been increased, and the weight has also reached more than 80 kg, with better stability, and an intimate built-in lighting function has been added. When it comes to Bosch's signature black technology, we must not mention the i-Dos intelligent delivery technology, which is not new today, but most i-Dos imitators find it difficult to achieve the maturity of i-Dos. The i-DOS can not only dispense detergent according to the amount of laundry, but also judge the degree of dirtiness of the laundry through the turbidity sensor, and adjust the amount as fine as 1 ml. In addition, i-DOS can also be set to different base dosages to ensure that detergents with different concentrations can have a consistent effect; One dosing is enough for a month, and the dispensing trough can be taken out separately for cleaning to avoid clogging of detergent clumps.
 
Only a few models of the 6 Series have added the i-DOS function, which is not standard, and some models also add functions such as OZONE sterilization, OZONE freshening, and home connectivity. OZONE sterilization is suitable for sterilizing clothes that cannot be washed at high temperatures, this function takes about 30 minutes, and the water mist in the sterilization process contains a certain concentration of ozone, and the structure of the microbial membrane is destroyed by the oxidation of oxygen atoms to achieve sterilization and deodorization. It is worth mentioning that ozone has a certain toxicity before it decomposes, and Bosch only has this function on high-end models, and the hatch is locked when running the program, and the whole machine has special sealing measures, which is far safer than other brands of ozone sterilization function. The home interconnection function is to use APP remote control to set up the washing machine, which has limited practical value. In terms of the most practical features, the i-DOS is also available.
 
The 8 series is upgraded to a full-touch color LCD screen on the basis of the 6 series, with a 360° door ring light that can display the washing angle, creating a high-end atmosphere, but the price is also more than eight or nine thousand yuan, and the function and performance are not much different from the 6 series. The price of the imported model Zhen "quality" series exceeded 10,000 yuan, and the motor speed was higher. However, consumers do not need to worry about imported or domestic when buying Bosch washing machines, the core components of washing machines are from first-line suppliers, and the performance and reliability of domestic models are not inferior.
 
It is worth complaining that the appearance of the Bosch drum washing machine can be described as mediocre, with a strong sense of plastic, especially the white model, the texture and the price do not match much, and the gap is not small compared with the Japanese and Korean brands of the same level.
 
In terms of washing and drying machines, the models are concentrated in the 4 series and 6 series, but unfortunately the models with drying function do not have i-DOS intelligent delivery technology. Bosch washer-dryer adopts air condensation technology, which is relatively rare on the market, and the common water condensing machine needs to consume a lot of water to dry clothes, while air condensation does not need to consume water, but the use effect is greatly affected by the ambient temperature, if the ambient temperature is high, the drying time will be extended, and it is not suitable for indoor with poor ventilation environment. Bosch washer-dryer models are also equipped with a hot air sterilization function, which is practical for clothes that are not suitable for washing at high water temperatures.
 
Bosch and Siemens home appliances have very similar models due to their special origins, and consumers can choose between two similar models after looking at specific functions. In terms of warranty, the two are also consistent, taking a one-year warranty for the whole machine, a three-year warranty for the main components, and a ten-year warranty policy for BLDC motors.
