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.

Just buy it. This vacuum/mop robot has saved me so much time. It was easy to set up, learned its route correctly and the mopping capabilities are exceptional.

Great deal

For all these replacement parts its not a bad deal. I love having the extra mips so I can exchange them and wash and still have extra. Ive already had to replace the sweeping brush bc a cat toy got tangled in it.

Great product

Worth every penny. Have used everything in the kit. The smell pod for the dump station only comes out when the robot is dumping
