The Brushless motor is small but very much you can (130,000 RPM and flow over 52 m/s). The air jet at maximum power (third level) is very powerful and allows you to blow the dust well from model cars or other objects such as monitors, keyboards and PCs. The drums is very large from 3000 milliamperes and is equipped with a cooling system through air sockets that exploit the cyclonic flow of the fan and also cool motor and electronics (warms up after a while that is used). There is a security check system anti overheating of the device and can recharge 2 Amps via charger with door USB Type C. The nozzle is also available, which concentrates the puff and attaches with a very comfortable magnetic support. Convenient to hold at maximum speed the drums will take about 15 minutes.
