The Genius X in Context
The Oral-B Genius X was a groundbreaking product when it launched in 2019 — it was the first electric toothbrush to incorporate artificial intelligence for brushing guidance. Using built-in motion sensors and AI algorithms, the Genius X could detect which area of your mouth you were brushing and provide real-time feedback through the Oral-B app, showing you which zones you had covered and which you had missed.
In 2025, however, the landscape has shifted dramatically. The iO series has taken over as Oral-B's premium lineup, offering the same AI capabilities along with a fundamentally better motor technology (linear magnetic drive vs. mechanical gears), quieter operation, and modern display screens. The Genius X's mechanical motor, while proven and effective, now feels like a previous generation product — because it is.
What It Does Well
The Genius X is still a genuinely good electric toothbrush. Its oscillating-rotating-pulsating action is the same proven technology used in the Pro 1000 and countless clinical studies. Six cleaning modes give you more options than any traditional-motor Oral-B model. The SmartRing is an elegant pressure indicator — a color-changing LED ring around the brush neck that shifts from green to yellow to red based on your pressure level. You can even customize the SmartRing color through the app.
The AI brushing recognition works well in practice. When you open the app and start brushing, it shows a real-time diagram of your mouth, highlighting each zone as you clean it. Over time, the AI learns your habits and provides personalized coaching suggestions. The travel case includes a USB charging port, which was innovative when launched and remains useful for travelers.
Battery life at 12 days is strong — longer than most iO models except the Series 8, 9, and 10. And because the Genius X uses standard Oral-B brush heads, replacement costs are significantly lower at $4-7 per head versus $8-12 for iO heads.
Why the iO Series 5 Is the Better Buy
At $119, the iO Series 5 costs $30 less than the Genius X at full price and delivers a superior experience in most ways. The linear magnetic drive is noticeably smoother and quieter than the Genius X's mechanical motor. The iO Series 5 has an LED display that shows your mode and battery level — the Genius X has no display, only the SmartRing. The overall feel of the iO handle is more modern and refined.
The Genius X does have advantages: six modes versus five, longer battery life, cheaper brush heads, and the included USB-charging travel case. But the iO Series 5's superior driving technology and more modern design make it the stronger recommendation for anyone buying new in 2026.
Where the Genius X becomes compelling is on sale. It frequently drops to $99-129, and at those prices it represents solid value — especially if the lower brush head costs matter to your budget over time.

Frequently Asked Questions
The iO Series 5 at $119 is the better buy. It uses the newer, quieter magnetic drive, has a display, and feels more modern. The Genius X's advantages — 6 modes, 12-day battery, cheaper heads — are outweighed by the iO Series 5's superior technology.
No. The Genius X uses standard Oral-B heads, which are cheaper ($4-7 each) and more widely available. It is not compatible with iO-specific heads.
The SmartRing is a color-changing LED ring that indicates brushing pressure: green for ideal, yellow for caution, red for too hard. The color is customizable through the app.
