• Vacuum cleaner that can be used for suction: floor mobile type (canister type), made in Japan (Since the shape of the nozzle is various in overseas products, the suction work cannot be done well.), suction work rate: 400 W or more is desirable, suction port dimensions: inner diameter 30 mm to 50 mm, suction method: paper pack type, cyclone type (The exhaust circulation type has an exhaust port at the suction port, and it cannot compress well because air is pumped in while sucking during compression work.)
• Auto lock valve type for easy compression by anyone.
