Dependsnon what it is and what value it can bring

I have xiaomi robot vacuum bought at nearly 500$

Between $200 to $500 depends on the function

Why not! There are super hi tech ones now.

I love Dyson. But it's so expensive

Depends on what function/load eased

Anything to help around the house.

If value for money absolutely yes

I'd love a Dyson vacuum cleaner!

Definitely. Love technology
