Hi thanks for reaching out, I'm Arlene an Independent Advisor.
I understand you're having trouble finding the Power Cleaning option for your Epson ET-1810.
Can you confirm if you've installed the full Epson driver from their official site—not just what Windows installed by default?
To access the Maintenance tab with Power Cleaning, download and install the full Epson Printer Driver and Utilities Combo Package for Windows 11 from the disclaimer: Epson Australia support page. After installing, go to Control Panel > Devices and Printers, right-click your printer > Printing Preferences, then check for the Maintenance tab.
Hope it helps. Please let me know for further assistance.
Thank you,
Arlene D.
