Snow-Joe now has a 100V cordless blower: https://mailchi.mp/snowjoe.com/umyzm...1?e=554c4bd77e
A friend has one of Snow-Joe's older 40V machines and I was skeptical that it was useful, but I used it on her driveway with about 8" of snow and it worked well; and longer than the manual said it should. And then I went in and swapped battery packs and finished up. I can only imagine how much better the 100V unit would do. Hopefully the battery pack cost will come down after a while.
The video is certainly impressive.
