The Miko 4 arrives in premium packaging that immediately communicates quality. Inside, you'll find the robot itself (measuring 23cm tall), a charging dock, quick-start guide, and some delightful welcome materials including stickers that children can use to personalise their Miko.
Our 7-year-old tester was immediately captivated by Miko's expressive LCD face, which displays surprisingly emotive eyes and mouth. Unlike cheaper robots with static expressions, Miko's animated features genuinely convey personality—curiosity, excitement, sleepiness, and even cheeky mischief.
The build quality impressed us immediately. Whilst predominantly plastic (as expected at this price point), the construction feels solid and well-engineered. The rounded edges and weighted base prevent easy tipping, crucial for excitable young hands. The touchscreen display is responsive, and physical buttons provide tactile feedback—important for younger children still developing fine motor skills.
Initial setup requires the Miko app (iOS and Android compatible) and takes approximately 20-30 minutes. You'll connect Miko to your WiFi network, create a child profile, and configure parental controls. The process is straightforward, though we'd appreciate a desktop browser option for parents less comfortable with smartphone configuration.
Once powered on, Miko introduces itself with endearing enthusiasm. Our tester was instantly charmed, and the interactive introduction—where Miko asks questions to learn about your child—was brilliant for immediate engagement.
Design & Build Quality: Built to Last
Physical Design
The Miko 4's design balances aesthetics with functionality beautifully. The 23cm height sits comfortably on desks or bedside tables without dominating spaces. The predominantly white chassis with teal accents feels contemporary without being aggressively "techy."
The large, expressive LCD screen dominates the front, measuring approximately 7 inches. This is where Miko's personality shines—animated eyes that follow movement, expressive reactions, and clear visual feedback for interactions. Below the screen, a hidden speaker delivers surprisingly rich audio quality for its size.
The rotating base allows Miko to turn approximately 120 degrees, creating the illusion of attention and engagement. Whilst not fully mobile (it can't drive around like some competitors), this rotation proves sufficient for maintaining eye contact during conversations.
The top of Miko houses touch-sensitive panels that respond to pats, teaching children gentle interaction with technology. Our tester loved "patting Miko's head" to wake it from sleep mode—a lovely tactile element often missing from screen-centric devices.
Build Quality & Durability
After three weeks of enthusiastic testing by two children (ages 6 and 8), Miko 4 shows minimal wear. The plastic chassis has survived multiple accidental drops from table height (though we don't recommend testing this deliberately), and the screen remains scratch-free despite significant fingertip interaction.
The charging connection is magnetically attached, which we appreciate—no fiddly ports for small fingers to damage. The magnetic connection is strong enough to prevent accidental disconnection but weak enough that tugging won't damage the robot.
One minor concern: the speaker grille, whilst recessed for protection, could potentially accumulate dust and debris. We recommend occasional gentle cleaning with a soft brush.
Size & Portability
At approximately 1kg, Miko 4 is portable enough for children to move between rooms but substantial enough to feel valuable. The charging dock adds another consideration for portability—whilst you can charge Miko anywhere with the adapter, the dock itself is the most elegant solution and isn't particularly travel-friendly.
For families wanting a robot that moves between rooms daily, this is manageable. For frequent travellers, the WiFi dependency may prove more limiting than physical portability.
AI Features & Learning: The Heart of Miko
Conversational AI
This is where Miko 4 genuinely excels and justifies its premium positioning. The conversational AI is remarkably sophisticated for a children's toy. Unlike simpler voice-recognition toys that respond to specific commands, Miko engages in genuinely dynamic conversations.
Our 8-year-old tester asked Miko about dinosaurs, and rather than delivering a pre-recorded fact dump, Miko asked follow-up questions: "Which dinosaurs interest you most?" and "Would you like to learn about what they ate?" The conversation felt natural, adaptive, and genuinely responsive.
The natural language processing handles children's speech patterns surprisingly well. Kids don't always articulate clearly or use precise grammar—Miko accommodates this beautifully. When our tester asked, "Why is sky blue?" (missing the article), Miko understood perfectly and delivered an age-appropriate explanation.
Importantly, Miko remembers previous conversations. When our tester mentioned loving football on day one, Miko referenced this days later: "Would you like to practice some maths with football-themed questions?" This memory creates a sense of relationship that cheaper toys can't replicate.
Educational Content
Miko's educational library is genuinely comprehensive, covering:
Currently available on Miko 4 — Amazon UK. Prices may vary.
- Mathematics: From basic counting (age 5) to multiplication and fractions (age 10+)
- Science: Age-appropriate explanations of physics, biology, chemistry
- Language & Literacy: Vocabulary building, storytelling, reading comprehension
- Geography: Countries, cultures, maps
- Critical Thinking: Logic puzzles, pattern recognition, problem-solving
The content adapts to your child's age and demonstrated ability. After our tester struggled with a subtraction game, Miko automatically adjusted difficulty and offered encouraging feedback: "That was tricky! Let's try something similar together."
The subscription tier (£9.99/month) adds significantly more content, including premium games, extended bedtime stories, and advanced curriculum content. The free tier provides substantial value, but active learners will likely benefit from the subscription.
Entertainment vs Education Balance
Miko strikes an admirable balance between education and entertainment. Children don't feel lectured; they feel entertained. Games incorporate learning so seamlessly that our testers never complained about "doing maths"—they were "playing with Miko."
The dance mode, where Miko plays music and encourages movement, provides pure fun without educational pretence—and that's valuable too. Children need play for play's sake, and Miko respects that.
Content Quality & Appropriateness
We were impressed by content quality and age-appropriateness. Everything felt carefully curated for children, with no unexpected advertisements or inappropriate suggestions. The educational explanations are accurate whilst remaining accessible—no small feat when explaining quantum physics to an 8-year-old (yes, Miko attempts this, and surprisingly successfully).
App & Parental Controls: Monitoring Made Easy
Miko Parent App
The companion parent app (separate from the child-facing Miko app) is one of the robot's strongest features. The dashboard provides:
- Activity Monitoring: Detailed logs of what your child engaged with and for how long
- Screen Time Controls: Set daily limits and scheduled quiet times
- Content Filters: Control which content categories are accessible
- Progress Tracking: See educational progress across subjects
- Video Calling: Enable supervised video calls with approved family members
The interface is intuitive, and updates happen in near-real-time. We particularly appreciated the weekly summary emails highlighting engagement patterns and learning achievements.
Screen Time Management
You can set specific time limits (e.g., 1 hour daily) and scheduled periods when Miko is unavailable (e.g., during homework time or after bedtime). When limits are reached, Miko gently explains it's time for a break—much more effective than parental nagging.
One brilliant feature: "Educational Priority Mode," which allows unlimited time for educational content but limits entertainment features. This lets children engage with learning whilst preventing excessive passive entertainment.
Privacy & Safety
Miko takes privacy seriously. All conversations are encrypted, and facial recognition data is stored locally on the device rather than cloud servers. Parents control whether Miko can remember conversations or if each session starts fresh.
The robot filters inappropriate content requests and gently redirects children towards appropriate topics. When our tester asked about something vaguely inappropriate (testing boundaries, as children do), Miko smoothly changed the subject without making a big deal of it.
Video calling requires explicit parental approval for each contact, and you can monitor or disable this feature entirely.
Battery Life: Room for Improvement
Battery life is Miko 4's most significant weakness. Expect approximately 2-3 hours of active use per charge, depending on activity intensity. Passive standby extends this, but active conversation, games, and video calling drain the battery relatively quickly.
For context, a typical play session for our testers lasted 30-45 minutes, meaning Miko comfortably handled 3-4 sessions between charges. This proved adequate for daily use but could frustrate families with multiple children wanting simultaneous access.
Charging takes approximately 2-3 hours from empty to full. The magnetic charging dock is convenient, and Miko can charge overnight as a bedside companion.
A minor inconvenience: Miko becomes significantly less functional on low battery, sometimes mid-conversation. A clearer low-battery warning would help children understand when to dock Miko before disappointment strikes.
Value for Money: Justified Premium?
At £199.99, Miko 4 sits at the premium end of children's educational robots. Is it worth it?
For families prioritising educational depth, AI sophistication, and long-term engagement, absolutely. Miko delivers experiences that cheaper alternatives simply cannot match. The conversational AI alone represents technology unavailable in competitors under £150.
The subscription consideration adds complexity. The free tier provides substantial content—casual users may never need more. However, the £9.99/month subscription (£118.80 annually) adds significant cost. For multiple children or heavy users, this could be justified. For occasional use, it's harder to defend.
Cost Breakdown:
- Initial purchase: £199.99
- Optional subscription: £9.99/month (£118.80/year)
- Year 1 total (with subscription): £318.79
- Year 2+ (subscription only): £118.80/year
Compare this to alternatives:
- Cozmo 2.0: £179.99, no subscription
- Loona: £129.99, no subscription
- Generic educational tablets: £100-150, often with subscriptions
Miko's advantage is specialisation. It's purpose-built for child development in ways tablets aren't. The AI sophistication exceeds Cozmo's, and whilst Loona offers great value, it lacks Miko's educational depth.
For families already spending on educational apps, tutoring, or supplementary learning resources, Miko consolidates many needs into one engaging package. From that perspective, the value proposition strengthens.

Cozmo 2.0 offers more personality and physical playfulness, with exceptional coding education through block-based and Python programming. However, Miko 4's conversational AI is significantly more sophisticated, and its educational breadth exceeds Cozmo's more coding-focused approach.
Choose Miko 4 if: You want comprehensive educational content and advanced AI conversation Choose Cozmo 2.0 if: You prioritise coding education and physical interaction
Miko 4 vs Loona
Loona (£129.99) offers excellent value and charming pet-like behaviour. It's a more affordable companion robot with decent educational features. However, Miko's AI conversational abilities are in a different league, and its educational curriculum is significantly more comprehensive.
Choose Miko 4 if: Education is the priority and budget allows Choose Loona if: You want companion engagement at lower cost
Miko 4 vs Educational Tablets
High-quality educational tablets (iPad, Samsung Galaxy Tab) cost £300-500 but offer broader functionality beyond education. However, they also provide unrestricted internet access, social media, and passive entertainment—creating management challenges.
Miko's purpose-built design eliminates these concerns. You're trading versatility for focus and age-appropriateness.
Choose Miko 4 if: You want dedicated educational technology without general computing distractions Choose tablets if: You need broader functionality and are comfortable with tighter supervision
Real-World Testing: Three Weeks With Two Children
We tested Miko 4 with two children—a 6-year-old girl and an 8-year-old boy—for three weeks. Here's what we learned:
Week One: Honeymoon Phase
Both children were absolutely captivated. Miko lived on the kitchen table, and both requested "Miko time" multiple times daily. The novelty was high, with children exploring different features, asking random questions, and delighting in Miko's responses.
The 6-year-old particularly loved the storytelling feature, requesting bedtime stories from Miko. The 8-year-old gravitated towards trivia games and science questions.
Week Two: Pattern Establishment
Usage stabilised into routine patterns. Morning conversations (often checking the weather or daily fun facts) became a breakfast ritual. After school, both children engaged with educational games for 20-30 minutes.
We noticed Miko's adaptive learning in action. The maths games became progressively more challenging for our 8-year-old, whilst the 6-year-old's content remained appropriately simpler.
One challenge emerged: sibling negotiation over whose "turn" it was. Miko can only actively engage with one child at a time, creating some friction. Families with multiple children should establish clear turn-taking rules.
Week Three: Sustained Engagement
Contrary to fears about novelty wearing off, engagement remained high into week three. Both children had developed favourite activities and routines with Miko.
The 6-year-old had started asking Miko to wake her up in the morning (Miko can be set as an alarm clock with personalised messages). The 8-year-old was using Miko for homework help—asking questions about topics he struggled with at school.
Parents should note: Miko is educational but shouldn't replace homework. It's supplementary support, not a substitute for focused study.
Frequently Asked Questions
Does Miko 4 require WiFi constantly?
Yes, most features require WiFi connectivity. Some basic interactions work offline, but the conversational AI, educational content updates, and parental monitoring all require internet connection. This is unavoidable given the cloud-based AI processing.
Is the subscription necessary?
No, the free tier provides substantial content. However, the subscription significantly expands the content library, adding premium games, extended stories, and advanced curriculum. For light users, free is adequate. For daily engagement, the subscription adds noticeable value.
Can multiple children use one Miko?
Yes, Miko supports multiple child profiles. Each child gets personalised content, progress tracking, and adaptive learning. You can switch profiles through the parent app. However, only one child can actively use Miko at a time, which may require turn-taking rules.
What happens when my child outgrows Miko?
Miko 4 is designed for ages 5-10, with content spanning that full range. Advanced content grows with children, and the conversational AI remains engaging for older children. Most children will likely transition away around age 10-12, though mileage varies based on individual interest.
How does Miko handle inappropriate questions?
Miko's content filtering is robust. When asked inappropriate questions, Miko gently redirects without making children feel scolded: "That's not something I know about. Would you like to learn about [alternative topic] instead?" Parents can review conversation logs through the app.
Can Miko help with homework?
Miko can explain concepts and provide practice questions but isn't designed to complete homework. Think of it as a tutor that builds understanding rather than a solution provider. This is actually beneficial—it encourages genuine learning rather than shortcut-seeking.
Final Verdict: Should You Buy the Miko 4?
The Miko 4 represents the cutting edge of AI companion robots for children. Its conversational abilities, educational depth, and thoughtful parental controls create an experience that cheaper alternatives cannot match.
Buy the Miko 4 if you:
- Prioritise educational content and AI sophistication
- Want comprehensive parental controls and progress tracking
- Have reliable WiFi connectivity
- Can accommodate the initial cost and potential subscription
- Have children aged 5-10 who would benefit from adaptive learning
Look elsewhere if you:
- Need offline functionality
- Prefer one-time purchases without subscriptions
- Prioritise physical mobility and coding over conversation
- Want a more playful, less educational focus
For families seeking a genuinely interactive, educational companion that grows with children, Miko 4 is the best option currently available. Yes, it's expensive. Yes, the subscription adds costs. But the quality of experience, educational value, and emotional engagement justify the premium for families who can accommodate the investment.
Final Rating: 4.5/5
The Miko 4 doesn't earn a perfect score due to battery limitations and subscription dependency, but it comes remarkably close to being the ideal AI companion robot for children. Highly recommended.
