Roborock Onyx3 Peristaltic Pump for S7 MaxV Ultra / S7 Pro Ultra Robot Vacuum
- Original Roborock Onyx3 peristaltic pump for S7 MaxV Ultra and S7 Pro Ultra robot vacuum systems. Precision liquid drainage component designed for reliable water flow, stable operation, and seamless replacement in compatible cleaning stations.

The Roborock Onyx3 Peristaltic Pump is a dedicated robot vacuum accessory designed for selected Roborock S7 series models, including S7 MaxV Ultra, S7 Pro Ultra, and S7 Max Ultra variants. As a key drainage and liquid transfer component, it supports the proper operation of the docking and water management system, helping your cleaning setup maintain dependable performance. Built as an original-style replacement part, this peristaltic pump is engineered for precise fluid movement and controlled flow.
Its compact motorized construction combines durable housing, integrated tubing connections, and electrical leads for stable installation and consistent compatibility with supported Roborock units. The peristaltic pumping principle reduces direct contact between moving mechanical parts and the transferred liquid, supporting cleaner operation and accurate pumping performance in automated cleaning environments. In practical use, the pump plays an important role in maintaining water circulation or drainage processes required by advanced robot vacuum stations.
Reliable liquid transport helps the system perform routine cleaning functions efficiently, while proper replacement of a worn pump can restore smooth station operation and reduce interruptions. This makes it a valuable spare part for users who want to keep their Roborock cleaning system functioning at the level expected from a premium automated floor care device.
