Some nice features but wimpy performance
on May 2, 2012
The variable speed switch is very smooth and easy to operate with one hand, and provides a very nice linear variation over its operating range. It also has a two position adjuster on the nozzle tip, which converts it from normal high flow (cfm) blowing to high speed (mph) blasting without the need to install and remove any attachments.
Unfortunately, the highest setting with the switch set on 5 and the tip set on high does not produce sufficient blast to budge almost any stuck debris or wet leaves. In fact, my 20 volt lithium 2-speed blower produces more blasting power on its high setting, even though it is only rated at 125 mph maximum, whereas the Greenworks 40 volt lithium blower is rated at 150 mph. I did notice that the impellers on both blowers are the same size and that the 40 volt blower produces a noticeably lower and quieter tone than the 20 volt blower on its high setting, which suggests that the motor speed is slower. Given that the 40 volt (146Wh) battery has nearly 3 times the capacity of the 20 volt (52Wh) battery, I would think that the maximum motor speed could be increased to produce more velocity and flow without significantly reducing battery run time.
Another consideration for taller people is that the single blower tube is very short and there is no extension provided, such that taller people may need to bend over or crouch in order to obtain the desired position and angle of the outlet. It is significantly shorter than the 2-piece tube on my 20 volt blower. This is great for me, since I'm only 5'-3" tall, but anyone over 5'-9" may find it uncomfortable.
This blower costs nearly twice as much as the 20 volt model, mostly because of the higher cost of the battery and charger, so I have to wonder if it's really worth it for the longer run time and variable speed switch.
