Samsung unveiled a new range of Stealth vacuum cleaners with improved performance and functionality. All new vacuums boast a noise level of only 58 dB, thanks to the whisper quiet sound technology, substantially reducing irritating noise. The dirt sensor detects dust and debris, and displays red light when there is dust and blue one after it is cleaned. What is more, the new Stealth vacuum cleaners come with improved suction brush that rotates over 40,000 per minute and features mini cyclone that collects fine particles more powerfully. Other features include Samsung patented Silver Nano Health System technology, Multi Chamber System with the dual filtration process which first isolates dust and debris from the air flow and then removes the finer particles in a second stage, remote handle control and HEPA filters.
