This expensive yet useful backpack laser is kind of a life saver for all those women and men who are ever willing to risk their lives to restore old buildings. The laser mechanism cleans without chemicals with the help of a 20 watt beam to vaporize pollutants like grease, paint and rust. It can safely be used on any surface and does not leave a residue. Using this backpack is convenient enough except that a protective eyewear is required. It costs a huge $53,700 but is worth the purchase.
