ROBERTS Dual Air Glider with Case can lift up to 800lbs, allowing a single user to be able to move heavy items like appliances, furniture, equipment, and machinery. Built with a powerful 1.75 HP blower and designed to use hovercraft-lifting principles, it allows heavy items to smoothly glide across flooring. An optional air vent helps control the air flow depending upon weight load, or reduce the lift in tight spaces. It includes a robust soft-sided case with a stronger carrying strap and soft shoulder pad to make transport easy.
