QEP Xtreme 8 in. Electric Suction Cup is expertly manufactured to lift, move and position non-porous materials including large format tile, slabs, and glass. It features a powerful grab with 264 lb. lifting capacity and steady suction, and is designed with a non-return valve that ensures the machine does not leak air. It has a 48-hour non-stop running capacity and a digital display to show battery power, indicating 99 when battery is fully charged, and a flashing red light to indicate when battery is lower than 15 and needs to be charged. It includes a 3.7VDC 5000mAh Li-ion rechargeable lithium battery with charging time of 6-8 hours. Hand-held and portable, it includes a USB-C charging cable, plus a durable carrying case for easy transportation and storage. For best results, wipe the tile surface clean before applying, and ensure the suction cup underside is clean and dust-free.
