Xiaomi Mijia Trimmer 2 Review: Precision Grooming, Now Waterproof

Xiaomi Mijia Trimmer 2 has 100,000+ reviews on JD.com with a 4.4/5 rating at ¥99 ($14). Users love the IPX7 waterproof design that allows easy rinsing, the precision stainless steel blade that trims nose and ear hair without pulling, and the compact size for travel. The main complaints are the battery life being about 30 days (shorter than the original model’s 45 days), the blade head being stiff to remove for thorough cleaning, and the lack of a travel lock. Conclusion: ✅ Worth Buying — the best budget nose/ear trimmer with genuine waterproof convenience.

Introduction

Xiaomi’s Mijia brand continues its tradition of high-value personal care products with the Trimmer 2, the successor to the popular original Mijia Trimmer. The key upgrade is IPX7 waterproofing, enabling wet cleaning and use in the shower.

At ¥99 ($14), the Trimmer 2 targets the basic grooming market — nose hair, ear hair, eyebrows, and detail work. It competes with the Flyco Trimmer and Philips Norelco at significantly lower prices, while offering waterproofing that many budget alternatives lack.

Design and Build Quality

The Trimmer 2 features Xiaomi’s signature minimalist design — an all-white cylindrical body with a single button on the side. The body is made from matte-finish plastic that feels clean and smooth. The device is compact at roughly the size of a lipstick tube, making it ideal for travel or bathroom storage.

The three interchangeable heads are stored in a clear plastic tray: a round nose hair cutter, a detail trimmer for eyebrows, and a precision trimmer for ear hair. The heads click onto the motor unit magnetically — satisfying and secure.

The IPX7 waterproofing means the entire device can be rinsed under running water. This is the biggest upgrade from the original model (which was only IPX5). The AAA battery compartment is sealed with a silicone gasket to prevent water ingress.

“The original Mijia Trimmer was already good. The Trimmer 2’s waterproofing is the killer upgrade — I rinse it under the tap after each use and it’s spotless. The blade doesn’t pull nose hair at all. Three head types cover everything I need. Best ¥99 I spend on grooming.” — JD.com verified buyer

Performance

The stainless steel rotary blade cuts nose hair cleanly without pulling. The rounded tip of the nose trimmer head prevents nicks. For ear hair, the precision head is small enough to maneuver safely. The detail trimmer works well for eyebrows, sideburns, and small facial hair areas.

The AAA battery makes it easy to keep running — no waiting for charging. A single alkaline AAA battery lasts about 30 days of daily nose hair maintenance (10-15 seconds per use). Rechargeable NiMH AAA batteries work fine.

The motor is quiet and well-balanced — it doesn’t vibrate uncomfortably. The magnetic head attachment is secure during use; no accidental detachment issues.

“The blade is sharp and precise. No pulling on nose hair at all. I use it weekly and one AAA battery lasts about 2 months. The waterproof body means I just rinse it under the faucet after use and it’s clean in seconds. The head removal for deep cleaning is my only complaint — it’s stiff.” — JD.com verified buyer

User Reviews by Theme

Waterproof Convenience

“The IPX7 cleaning is a game-changer. With my old non-waterproof trimmer, cleaning involved taking it apart and brushing — annoying. Now I just rinse under the tap and it’s done. This alone makes the Trimmer 2 worth the upgrade from the original.” — JD.com verified buyer

💡 Summary: Waterproof cleaning is the standout feature. Makes maintenance effortless.

Cutting Comfort

“Zero pulling. I have thick, coarse nose hairs and previous trimmers pulled painfully. The Trimmer 2’s blade is sharp enough to cut cleanly. The rounded tip prevents nicks. Best nose trimmer I’ve owned.” — JD.com verified buyer

💡 Summary: Cutting comfort is excellent across all head types. No pulling or tugging reported.

Battery Life

“The AAA battery is both a pro and con. I like that I can just replace it when dead instead of waiting for charging. But the 30-day life is shorter than the original’s 45 days. I use rechargeable Eneloop batteries to keep costs down.” — JD.com verified buyer

💡 Summary: Battery life is adequate but shorter than the previous generation. AAA format allows easy replacement.

Head Switching

“The magnetic head attachment is convenient — just swap heads for different grooming tasks. The storage tray keeps everything organized. The heads are getting harder to find as individual replacements though.” — JD.com verified buyer

💡 Summary: Quick-change magnetic heads are convenient. Replacement head availability is a concern.

Purchase Recommendations

✅ Worth Buying (¥99)

💰 Premium Pick

At ¥199, the Panasonic ER-GN30 offers longer battery life (60 days), easier blade removal, and a travel lock. Best for frequent international travelers who need the extra features.

⚠️ Budget Warning

FAQ

Q: Xiaomi Mijia Trimmer 2 vs original Mijia Trimmer — what’s new? A: The Trimmer 2 upgrades from IPX5 (splash-proof) to IPX7 (fully washable/rinseable), adds magnetic head attachment (replacing clip-on), and has a redesigned blade for smoother cutting. The trade-off is slightly shorter battery life.

Q: Can the Trimmer 2 be used for beard trimming? A: The detail trimmer head works for beard line definition, mustache trimming, and sideburn shaping. For full beard trimming, a dedicated beard trimmer with adjustable guards is more practical.

Q: How do I clean the Trimmer 2 properly? A: After use, rinse the entire device under running water while running the motor. For deeper cleaning, the blade head can be removed (it’s stiff at first). Dry thoroughly before storage. Use the included brush for stubborn debris.

Q: What battery does the Trimmer 2 use? A: A single AAA battery. The device works with alkaline, lithium, or rechargeable NiMH (1.2V) AAA batteries. A fresh alkaline battery lasts about 30 days of daily use.

Q: Are replacement heads available for the Trimmer 2? A: Yes, sold in packs of 2 on Xiaomi’s JD flagship store for about ¥39. Each replacement head contains all three attachments. Users recommend replacing the blades every 6-12 months for optimal cutting performance.
