Our robot Eufy vacuum hates the sun. When it hits a sunny spot on the floor, it thinks it is a drop off and reverses course.

I've spoken with Eufy support and they know off this quirk. The solution seems to be "vacuum when it isn't sunny" which works for me. Yoof was under $100 and does more than its share of the dust removal.

We put googly eyes on it to anthropomorphize it like any self-respecting robot owner does. If it hates the sun then I am wondering if some vampire teeth are in order.
