The pull-out kitchen faucet works by allowing the spray head to extend down into the sink. You turn the water on using the single handle as usual. At the same time, you can mix the hot and cold water using the same handle. The water from the handle goes back down to the main controller unit under the sink. Has a longer hose than a pull-down, so you can swivel it to the side to fill pots on the countertop; a high spout works well for filling tall pots.
Three functional water flow modes: Stream, Spray, Dual Aquablade. Soft stream mode is used in regular; Spray makes sense in large area cleaning; High-Pressure Dual Aquablade comes when solve flush stuck residue. Hope you like this video and the functions of the Sanliv Pull-Out Spray Kitchen Faucet.
