Because of carpet"s size smaller, using of vacuum cleaner for large carpet is decresed and increased the using of Air Turbine for domestic vacuum cleaner for small size carpet. Also Air turbine is essential part to clean the car seat, small carpet for stairs. Besides the Air turebine, there are vacuum cleaner which using similar way to use kinetic energy for rotating the fan. Exising cleaner is blanket brush which is that have bigger agitator than Air turbine, but it use same way to rotating agitator. However, the blanket"s friction is lower than carpet"s friction, it doesn"t need higher torque than Air turbine. So result of studiying the Air turbine contribute improvement of performance for other cleaner.
