I have one and we love it, so I should know the answer to this but I don't.
We use it to clean at the same time each day via Alexa.
DS2 doesn't have Alexa,. Can you set it to start work at a regular time just using the remote control? Or WIFI?
DS1 has two of these wonderful household helpers. DS2 is very impressed with ours so I thought it a good idea for Christmas.
