Looking for the best Vacuum around 450 euros

Hello

I’m looking for the best robot vacuum mainly hard floor but there might be toys and cable in the ground. Also I have a carpet that is no very thick.

I just want a plug and play solution with very little maintenance, I’ve heard some models promise 100 days with no maintenance (is that even true?)

what would you recommend ?

I have to say I’m leaning toward dreame vacuums but so many models, love Romo too but it’s too expensive.

I have a budget around 450 euros

Thank you
