Blade types like this and the Cen-Tec Sidewinder are much more efficient and cover a lot more ground than traditional T-bar vacuums. The Sidewinder makes better use of less airflow with a narrower profile, e.g. B. Cordless vacuum cleaners, but the connection hoses and rivets are more durable on the Problade. Combine this with a Supercoach or something that can generate >70L/s suction and you can cover half a hectare in under an hour. My only complaint is that the rear hose clogs easily and for some reason, even with our monstrous 100L/s vacuum, it won't hold an eraser, paperclips or staples for a lifetime.
