Great customer service.
Glad I bought the protection. The vaccume worked great for a while then quit holding a charge. They refunded my purchase price (Amazon gift card).

Really good to have
Size: for Q S5V
After owning a wireless vacuum mop I knew it was good to have extra parts like this on hand so I ordered these when I ordered the robot vacuum. Oh boy... when my vacuum did the dreaded run through dog poop I was very happy to be able to just throw the other parts away and replace them on the spot.

Great Value and Perfect Fit for My Qrevo
Size: for Q S5V
This 34‑piece replacement set has been a great buy for my Roborock Qrevo. All the parts fit perfectly, install easily, and work just like the originals. The brushes and filters snapped right into place, and the mop pads feel thick and durable. After replacing everything, my vacuum immediately picked up more dust and debris.
One thing to note: the kit didn’t include any instructions for the scent packs, so I placed them in the dust bag—hopefully that’s the correct spot. It would’ve been helpful to have a quick guide included.
Overall, the amount of pieces you get for the price is a fantastic value, and it’s great having plenty of backups on hand.
