For the Roborock Qrevo Curv 2 Flow, the DuoDivide brush rollers last 12-18 months, and the mop roller similarly lasts 6-12 months. Both robots notify you via the app when replacement parts are due.3. Do these robots work with voice assistants like Alexa or Google Home?

Absolutely. Both the eufy OMNI S2 and Roborock Qrevo Curv 2 Flow support Amazon Alexa and Google Assistant.
