Xiaomi offers high-quality vacuum cleaners. This Xiaomi Mi Cordless Vacuum Cleaner is designed to provide deep cleaning for your home. Thanks to its 100,000-revolutions-per-minute rate and its 9 cyclones, it offers a great suction power that can filter dirt particles up to 0.3 microns in size and it also can vacuum up to 99.7% of sand and dust particles. What is the secret to a high-performance vacuum cleaner? Engineers have discovered that high levels of suction can invite micro-particles of dust to clog up a vacuum, causing suction to slow down with use. Mi Handheld Vacuum Cleaner uses an aerodynamic structure that uses a 9-cyclone engine, effectively separating dust particles as they pass through. The result is lasting high-powered suction that does not decline as you use this Xiaomi Mi Handheld Vacuum Cleaner, the best cordless vacuum on the market.
