Rechargeable Vacuum Cleaner is also a Handheld Vacuum Cleaner. Some rechargeable Vacuum Cleaner has charger base with multifunction,so we can store easier. Although it is basic configuration,it has complete accessories. So you can use in any places. Its basic configuration's battery is NI-CD(1200MAH),but if you want to change,it is allowed. You can change to NI-HI battery or battery pack. If the battery is Replaced,the unit price will change,too. So please consider clearly. Now I will show you some pictures about rechargeable vacuum cleaner.

Market prospects
As the world's most populous country and the fastest growing economy, China's LED lighting applications have huge market potential. The data shows that the domestic market demand for incandescent lamps and energy-saving lamps in 2012 reached 1.176 billion and 1.269 billion, respectively, the market demand for straight fluorescent lamps is 830 million, and the market demand for circular fluorescent lamps is 800 million. The demand is 755 million. These traditional lighting sources and lamps are the target replacement market for LED lighting fixtures. With the improvement of cost performance, LED lighting fixtures will gradually enter these market areas, bringing huge market development space.
It is reported that the consumption of lighting fixtures in China is mainly provided by domestic enterprises. The share of imported products in China is less than 5%, while nearly 70% of domestic production is used for export. The good lighting industry foundation not only provides a reliable product supply for the domestic LED lighting market application, but also provides a very good support for the domestic LED lighting industry to improve the cost performance of LED lighting through scale effect.
In May 2012, the State Council proposed subsidies for energy-saving appliances in the “12th Five-Year Plan†of the National Basic Service System.
On February 17, 2013, the National Development and Reform Commission issued the “Energy Saving Plan for Semiconductor Lighting Industryâ€. The plan clearly stated that the output value of LED lighting energy-saving industry will increase by about 30% annually. By 2015, the industrial scale will reach 450 billion yuan; the localization rate of LED chips More than 80%; the luminous efficiency of the core devices and the quality of the applied products have reached the international advanced level. There are indications that the LED lighting market has broad prospects and is full of opportunities.
Complete industrial chain
According to relevant sources of the Economic Development Bureau of the Development Zone, the semiconductor lighting industry in Yangzhou Economic and Technological Development Zone has formed a complete industrial chain of “substrate-epitaxial chip-chip-package-applicationâ€.
Upstream epitaxial wafers and chip manufacturers represented by Yanyang Optoelectronics currently have sufficient orders. It is understood that 37 MOCVD equipments in the No. 1 workshop of Shengyang Optoelectronics Co., Ltd. are fully produced, with an annual production capacity of 100,000 pieces, an increase of 50% over the same period of last year. Orders have been placed in June. The company is planning to establish a research and development center, and is ready to use the No. 2 workshop to expand production scale. It is estimated that the annual output value will be 500 million yuan, a year-on-year increase of 48%.
In the field of midstream packaging, the development zone Yuli Electronics has sufficient orders throughout the year. The person in charge of the company told the reporter that Yuli Electronics has added 7 packaging equipments this year and 6 SMT production lines are fully loaded. It is estimated that the annual output value will be 1 billion yuan, a year-on-year increase of 75%.
“Development LED downstream application companies are mainly concentrated in the field of lighting.†According to relevant persons from the Economic Development Bureau of the Development Zone, the district has gathered core lighting, Futai Lighting, Haohua Optoelectronics, CNPC Tiangong, and new generation lighting. Jinbei Optoelectronics, Radix Optoelectronics and other enterprises. However, because the pre-lighting market has not yet started, and the national and industry standards have not yet been formulated, the competition of enterprises is fierce, the overall quality of products is not high, and market development is difficult.
Independent research and development capabilities
With the increasing emphasis on the promotion of LEDs in China, foreign LED giants have also entered the Chinese market, especially the introduction of the "Semiconductor Lighting Industry Energy Conservation Plan" at the beginning of the year, further accelerating the pace of investment by foreign companies. "The development zone can take this opportunity to increase the introduction of LED lighting terminal enterprises, thereby driving the release of upstream enterprises' production capacity and making the scale of the LED industry in the region." Relevant sources revealed.
"We should make full use of the advantages of the national semiconductor lighting industry base, and actively appeal to the industry leading enterprises in the region to participate in the formulation of national and industry standards." According to relevant sources, such as Radix Optoelectronics, which accounts for 45% of the global optical lens market share, praise Optoelectronics is located in the first square array in China in the field of LED epitaxy and chip. The dry-light photoelectric quaternary red-yellow LED epitaxy and chips account for more than 45% of the domestic market. By participating in standards development and gaining the right to speak in the industry, enterprises can quickly enter the fast lane in the future development and market development.
"Enhance the independent research and development capabilities of enterprises to take the initiative in the industry competition." The relevant person of the Economic Development Bureau of the Development Zone believes that enterprises should be actively guided to increase investment in research and development, set up product research and development centers, improve the technological content of products, and enhance the competitiveness of enterprises. It is understood that Zhongke Semiconductor is actively applying for a national-level lighting engineering technology research and development center, and Yangyang Optoelectronics plans to build a research and development center by the end of this year. 
Strengthening independent research and development capabilities, building a complete LED industry chain in Yangzhou Economic Development Zone
In recent years, the LED industry has been growing at a high speed under the pull of the backlight market. According to the statistics of the High-tech LED Industry Research Institute, the total output value of China's LED industry in 2012 reached 205.9 billion yuan, a year-on-year increase of 32%. Among them, the output value of LED upstream epitaxial chips, midstream packaging and downstream applications were 7.2 billion yuan, 39.7 billion yuan, and 1590 respectively. 100 million yuan, an increase of 20%, 24%, 37% respectively. Under this background, how is the development of the LED industry in Yangzhou Economic and Technological Development Zone?
