Thank you for your question. The Esque faucet 9181-DST didn't always have ShieldSpray Technology. If the faucet was manufactured before October 21, 2017, it will not have the ShieldSpray Technology. You can purchase the sprayer assembly that includes ShieldSpray Technology. The sprayer assembly is RP90840. Here is a link to the part:
If the faucet was manufactured after October 21, 2017, it should include the ShieldSpray Technology. There is an extra button on the sprayer assembly that will engage this spray.
The manufacture's date should be labeled on the faucet's box or the tag labeled with the model number on the supply line under the sink, on the faucet.
