One of the best parts of owning a clip-on companion robot is moving it across your wardrobe—from a structured Monday-through-Friday work tote to a weekend crossbody bag or travel backpack. Because Yukai Engineering's Mirumi houses a motorized neck actuator and touch/sound sensors inside a 155 g body, using the right hand placement when unwrapping and re-wrapping its arms keeps the mechanism working smoothly for years.

1. Correct vs. Incorrect Handling When Swapping Bags
According to Yukai Engineering's official US specifications (source) and US FAQ (source), Mirumi measures 100 × 110 × 140 mm, weighs approximately 155 g, and is designed for straps of 10–15 mm diameter.
| Swapping Step | Correct Technique (Protects Actuator) | What to Avoid |
|---|---|---|
| 1. Holding the Body | Support the lower torso/base in one palm while unwrapping the plush arms with your other hand | Never pull by the head: Pulling on the head puts torque on the internal rotary neck mechanism |
| 2. Checking the Next Bag's Strap | Confirm the new handle or auxiliary loop is approximately 10–15 mm in diameter | Avoid forcing the arms around wide 40 mm flat webbing where they cannot close securely |
| 3. Checking Hand Cleanliness | Swap with clean, dry hands away from hand lotion or rain | Remember Mirumi's custom fur is not washable and non-removable (source) |
2. Rotating Bags vs. Pairing Colorways
Whether you move one companion across every bag or keep Mirumi Robot Gray on your dark weekday tote and Mirumi Robot Ivory or Mirumi Robot Pink on your weekend handbag, supporting the torso during every strap swap protects its expressive head-turning motion.
