Using the sweep tool can help you save time if you'd like to sweep the floor on multiple ENS names at once in a specific collection.
A video tutorial on how to use the collection sweep tool can be found here.
To perform a collection sweep navigate to the specific ENS Collection page that you are interested in. Click the Sweep button on the ENS Collection page that you would like to offer on.
2. In the popup sweep menu slide the gray circle to the desired amount of names you would like to sweep from the floor. Once you have confirmed the names and the price press the add to cart button to continue.
3. If not done so already, you will be prompted to connect your wallet before placing a collection offer. Supported wallets currently include MetaMask, Rainbow, Coinbase Wallet, and WalletConnect.
4. Once your wallet is connected and you have added the names to your bulk checkout cart using the sweep tool press Checkout to start the transaction. A wallet interaction to complete the sweep purchase of your selected ENS names will appear after clicking checkout. Buyers are responsible for paying the Ethereum gas fee when completing a purchase.
5. A confirm transaction banner will appear and automatically refreshes the window when the transaction is processed. After the transaction is confirmed on the Ethereum Blockchain a confirmation window will display your ENS names purchased. Click the OK button to continue. Your new names will now display in your Collection tab under My Profile!
