Easy to use Intelligent electric suction cup, one-k start, lightning adsorption, simple operation, easy to use. * Powerful brushless motor, strong vacuum suction, more stable load-bearing adsorption. The matte surface can absorb both smooth and uneven surfaces, such as the back of ceramic tiles. The suction force for absorbing smooth surfaces is 220KG. If the matte surface absorbs uneven surfaces, the suction force is 130KG. * Strong battery life, with removable lithium battery, longer service life, higher power, high temperature resistance and low temperature resistance. * Anti-leakage sensor, automatic air replenishment. Electronic self-priming system maintains effective suction at all times. * Pressure gauge displays in real time. Upgrade the pressure gauge device to display real-time air pressure during operation.
