With the launch of The Sqair, we’ve retired the Cannon. We’re sad to see it go after 4 years of dedicated pollution-busting service. However, we retired it because The Sqair is more powerful, quieter, and much much better looking than the Cannon. We developed The Sqair over 3 years with an eye to improving on the shortcomings with the Cannon. We’re happy with the final product! We think you’ll like it too.
