I've been looking at the budget end of the Robot vacuum market and came across both these units. EUFY (Anker) 30% for one day only on the EUFY Robovac 35c and EUFY Robovac 11s. Both units seem to get good review, with the 35c offering slightly more power and WIFI connection/Alex voice control.
Thanks
From my initial research apparently Xiaomi is a better option
