GARBAGE!!
Buyer beware. I paid $749.99 for a brand-new Roborock S8 MaxV Ultra with Refill & Drainage System, and it was defective from the very first use. It would not power on or charge normally. I completed all troubleshooting, provided photos, videos, and the serial number, and Roborock ultimately confirmed the unit needed repair. I requested a refund because I paid for a brand-new product, not a repaired one before I ever got to use it. Roborock denied the refund and also said a replacement was no longer available because the 30-day period had passed. Their only solution was repair. What concerns me even more is that I found multiple customer reviews describing the same situation as mine — brand-new units failing from the beginning — and other reviews describing problems returning again after repair. I understand companies have policies, but relying on a 30-day policy when a premium product was defective from its very first use does not give me confidence in the brand or the resolution being offered. For a product at this price, I expected much better quality control and customer support. Brand-new should mean working from day one. In my experience, this was a waste of money.
