KAMNIK Xiaomi Mijia 1C 2C Mi Robot Mop 2 Spare Parts Kit

KAMNIK Replacement Accessories for Xiaomi Mijia and Mi Robot Vacuum Mop 2 Series

Regular maintenance is the single most effective way to preserve the cleaning performance of any robot vacuum, and KAMNIK has built a reputation for producing reliable replacement accessories tailored to popular Xiaomi robot vacuum models. This accessory kit is compatible with the Xiaomi Mijia 1C, Mijia 2C, and Mi Robot Vacuum Mop 2 (model STYTJ03ZHM) — a family of well-regarded robot vacuums known for their combination of laser navigation, efficient suction, and simultaneous mopping capability. Whether you need to replace worn side brushes, a clogged HEPA filter, or a saturated mop cloth, KAMNIK offers the individual components needed to restore your robot to like-new cleaning condition.

This listing is available in multiple variants, with one of the most commonly selected options being the four-side-brush pack. Side brushes are among the highest-wear components on any robot vacuum, as they are in constant contact with floor surfaces and room edges during every cleaning cycle. Replacing them on a regular schedule is one of the most impactful maintenance steps you can take to maintain edge-cleaning coverage and overall debris pickup efficiency.

Compatible Xiaomi Robot Vacuum Models

Xiaomi Mijia 1C

The Xiaomi Mijia 1C is one of Xiaomi's entry-level 2-in-1 robot vacuums, combining suction and mopping in a compact form factor. It uses LDS laser navigation for systematic room coverage and features a large dustbin. The side brushes used on the Mijia 1C are responsible for sweeping debris from room edges and corners into the suction path of the main brush, making them critical for thorough edge and corner cleaning performance.

Xiaomi Mijia 2C

An upgrade over the 1C, the Mijia 2C features stronger suction and improved filtration. It shares a similar accessory architecture with the 1C, using compatible side brushes, filters, and mop cloths. The HEPA filter on the 2C plays an important role in maintaining indoor air quality, capturing fine dust and allergen particles before they can be exhausted back into the room.

Mi Robot Vacuum Mop 2 (STYTJ03ZHM)

The Mi Robot Vacuum Mop 2 represents a step up in Xiaomi's consumer robot lineup, featuring precision LDS navigation, real-time mapping, and strong simultaneous vacuuming and mopping performance. Keeping the side brushes, filter, and mop cloth in good condition on this model directly affects how well it maintains its mapped cleaning routes and how thoroughly it cleans across all floor surface types.

Key Replacement Components

Side Brushes (4-Pack Option)

The side brushes are spinning spiral-bristle components mounted on the underside of the robot at the front corners. During operation, they rotate outward to sweep dust, debris, and pet hair from along walls, baseboards, and room edges into the central cleaning path where the main suction inlet can capture them. Over time, the bristles become bent, worn, or broken from repeated contact with floor surfaces and furniture legs. Replacing them restores the sweeping radius and ensures full edge coverage during cleaning cycles. The four-brush pack provides enough replacements to last through multiple maintenance cycles.

HEPA Filter

The HEPA filter is positioned within the dustbin assembly and acts as the final barrier between the collected debris and the air exhausted by the vacuum motor. A clean, unclogged HEPA filter maintains strong airflow through the machine, which directly supports consistent suction power. As the filter accumulates fine dust and particulate matter, airflow resistance increases and suction performance drops. Regular filter replacement — typically every one to three months depending on usage and household conditions — keeps suction power at its designed level and helps maintain healthy indoor air quality.

Mop Cloth

The mop cloth attaches to the water tank module on the underside of the robot and provides the wet-cleaning function during mopping cycles. As the robot navigates across hard floor surfaces, the mop cloth distributes water from the reservoir and physically wipes the floor surface clean. Mop cloths accumulate dirt, oils, and grime over time and become less effective as their microfiber structure becomes saturated. Replacing the mop cloth restores the robot's ability to leave floors genuinely clean rather than simply redistributing surface moisture.

Maintenance Schedule and Best Practices

For households running their Xiaomi robot vacuum daily, KAMNIK recommends a regular maintenance schedule to get the most from replacement accessories. Side brushes typically last one to two months before bristle wear becomes noticeable. HEPA filters should be tapped clean weekly and replaced monthly to bi-monthly depending on dust levels in the home. Mop cloths are best replaced every two to three months, or more frequently in households with pets or high foot traffic. Following this schedule ensures that every cleaning cycle delivers the full performance that the Xiaomi Mijia platform is designed to provide.
