Xiaomi Mijia 1S – Plus.Parts® Replacement Parts Set

The Xiaomi Mijia 1S represents a meaningful step forward from the original Mi Robot platform. Built on Roborock hardware with an updated LiDAR sensor and enhanced suction, the Mijia 1S maps rooms with greater precision and handles carpet more effectively than its predecessors, a mid-range robot that earns its position in the Xiaomi lineup through genuinely improved daily cleaning performance. Its brush and filter system carries that performance across every session: the main brush works the floor surface with each pass, side brushes extend cleaning coverage to edges, and the filter captures fine particulate in the airstream before exhaust. The 1S runs its consumables through their wear cycle across daily use, the main brush accumulates fibre, side brushes lose sweep radius, the filter restricts airflow as it fills. Addressing all three together keeps the robot performing at the level that makes the Mijia 1S worth running daily.

This maintenance pack provides a direct-fit replacement set for each consumable. It contains Plus.Parts® components selected for compatibility with the Xiaomi Mijia 1S: main brush, side brushes, and filters, six parts in total. Every item matches the robot’s original mounting points and dimensions, and covering the complete service interval in one order avoids the disruption of partial replacement.

Brush compound and filter media matched to the robot’s airflow and daily-use requirements, the set is built to perform across the replacement cycle. If a question comes up about your specific Mijia 1S variant or anything else about your order, our team responds personally.
