I bought a Roborock Q8 MAX which arrived defective, I plugged it in to charge and it wouldn't charge. I spoke with the seller, I spoke with the company itself, they sent me instructions and I sent them back videos of its failure. In short, we concluded that it is defective and I am sending it back for warranty.

A couple of months of waiting!!!!!!!! Two months without a vacuum and minus 300 euros!!!!! While I was emailing the company every other day, they didn't even know where my vacuum was, the seller had to push them and we got a refund. Thankfully, the seller was interested and took action on the issue, he lost the sale but justified me, his customer.

However, I don't know if the others will be so lucky. The guys are so clueless that they had taken the vacuum for repair and a month later, while I was in communication with them, they told me to ask my seller to tell me where the vacuum is.

I do not recommend either the vacuum or the company
