If you’re looking for a replacement filter for the **Xiaomi Robot Vacuum S10T**, be careful — a lot of Xiaomi robot vacuum filters look very similar, but that doesn’t mean they will fit the S10T.

The safest way is to check a few details before buying.

**Correct S10T model information:**

* Xiaomi Robot Vacuum **S10T**
* Model: **STFCR01SZ**
* EU version: **BHR5887EU**
* Filter part reference: **C015550042000**

From the replacement filter shown in the photos, the dimensions are approximately:

**142 × 40 × 18 mm**

**Net weight: about 30 g**

Also pay attention to the physical design. The S10T-style filter has a **clear plastic frame, black sealing border, pleated filter material, and a small round metal/magnetic-looking insert on the side**. That side detail is especially useful when comparing listings that otherwise look almost identical.

Xiaomi officially states that the S10T uses a **Hall-effect sensor to detect the dustbin**, so the S10T has magnetic sensing hardware in this area, although Xiaomi does not explicitly state that the round insert on the filter itself is the trigger.

**Don’t buy a filter just because the listing says “Xiaomi S10.”**

My suggestion before ordering:

**Check the model number → compare the 142 × 40 × 18 mm size → compare the side round insert → compare the black seal and plastic frame.**

If one of these details is different, I’d double-check with the seller before ordering.

It’s much easier than finding out the filter doesn’t fit after it arrives.
