The body is small and can be drilled into the base, and the bottom can also be sucked. With a diameter of only 8.2CM, it can easily go deep under seats, door gaps, cup holders, etc. to professionally clean gaps and clean more thoroughly 30 minutes of uninterrupted use. Wireless is more energy-saving and can be used even when the engine is turned off. Once , the entire car is cleaned in 30 minutes. No need to the car, so it can be used uninterrupted. Intelligent power display saves energy while protecting the battery DC digital motor - hurricane-type large suction power, 33000 rpm or MIN DC digital motor, 120W high rated power, and smooth power output curve to provide continuous and stable power achieve strong motor performance through analysis and simulation calculations To achieve 4000PA high vacuum and 60mm diameter turbine maple leaf, through multiple numerical simulations, the number of blades, curve, impeller outer diameter, air inlet diameter, impeller aspect ratio, impeller inner and outer diameter ratio, inlet vortex, and outlet turbulence After more than 10 pieces of data, the design was optimized for 2 months and by real sample testing, resulting in a vacuum degree of more than 4000pa (tested under 12V state) and a high flow rate of 500L or min, ensuring a small body and large suction power The wind energy conversion rate is as high as 98percent . Two engineers continuously simulated and tested the air duct design through fluid mechanics for more than a month. Through continuous optimization of the air inlet cavity, air outlet cavity, and air outlet holes, the temperature, softness and flow of the air were further reduced. The energy loss is controlled below 2percent , thereby indirectly improving the suction power Equipped With 3 Types of Conversion Heads for Blowing Air And Dust for Different Purposes Working Temperature: -10-45 Charging : Type-C Charging Time: About 3 Hours Colour:Green Material:ABSandPCandMetal Package Contents: 1x Turbo Jet Fan 1x Brush 3x Different Air Nozzles 1x Power Cord 1x Comes with instructions in Chinese and English Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm.
