Professional Power with the benefits of premium cordless technology.It is air volume, not air speed that moves the debris you need to clear. The BL300 has a very high air power, up to 841 cubic metres of air/hour, measured at the nozzle (some manufacturer's measure at the body to show a higher, but unrealistic, figure, while most quote irrelevant air speed). This means the BL300 performs comparably with very large petrol commercial blowers, yet retains the compact dimensions, easy handling, light weight of a small handheld blower. With all the benefits of cordless tech like instant start, zero emissions and more, it could be  called having your cake and eating it.
