The Smart Pressure Sensor helps to keep you from brushing too hard to protect your gums and enamel. 3D Teeth Tracking and AI Recognition use an interactive color display to help guide you to your best clean for all areas of the mouth. A 2-minute quadrant timer comes built-in that pulsates every 30 seconds, ensuring a complete clean. The frictionless, smooth magnetic drive system transfers energy to the bristle tips for a clean that wows. Replace your Oral-B iO Series Replacement Brush Heads every 3 months for best results.

Review: Oral-B iO Series 6 is Solid Brush, but the iO Series 9 is in a Class of Its Own - If you're debating between the Oral-B iO Series 6 and Series 9, I get it—I was in your shoes not too long ago! As someone who travels frequently for work, I invested in both, hoping to streamline my packing routine. I thought I’d just be dealing with a few tweaks here and there, but wow, was I wrong. First, let’s talk brushing performance. Both models use Oral-B's "magnetic iO technology," which combines oscillating-rotating and micro-vibrations for an experience that feels more like ultrasonic brushing than the older Oral-B series. After each session, I’m left with that fresh-from-the-dentist smoothness, and yes, both models deliver equally in that department. If the actual brushing is what matters most to you, the Series 6 holds up well. But once you start looking at the extras, the Series 9 really starts to shine. Let's talk about the charging setup. The Series 6 has a basic charger—functional, but nothing to write home about. In contrast, the Series 9’s charger feels like it could double as a paperweight in a windstorm; it’s sturdy and, dare I say, elegant. And for those constantly on the go, here’s where the Series 9 really scores big: its case isn’t just a case; it's practically a mini power station! The travel case for the Series 6 feels flimsy, like something you’d get in a happy meal, but the Series 9’s case could probably survive a fall down a mountain (though I’m not volunteering to test that). Battery life is where the Series 9 once again pulls ahead. I can usually go about two weeks without recharging with both models, but the extended battery life with the Series 9 means I could probably escape into the wilderness and brush my teeth for a month with power to spare. (Hello, camper toothbrush!) And let’s get to the tracking tech, my fellow data nerds. The Series 6 offers decent tracking with six zones, which is enough to keep tabs on each part of your mouth. But the Series 9? We're talking 16 zones of tracking, folks. This means you’re not just getting feedback on the upper and lower quadrants but the front, back, sides, and—let’s be honest—probably nooks and crannies I didn’t even know existed. The 16-zone tracking is almost like having a dental assistant saying, “You missed a spot… and another one.” If you’re someone who thrives on that level of accountability, the Series 9 is your holy grail. Yes, the iO Series 9 is significantly more expensive than the Series 6, and if you’re mostly after a good brush, the Series 6 will serve you well. But if you're looking for a tech-packed marvel with all the trimmings—like precise brushing analytics and top-notch travel accessories—the Series 9 is worth the investment. So which one am I tossing into my suitcase? The Series 9. Because sometimes, your teeth deserve the VIP treatment.
Review: It's absolutely amazing 👏! What a game changer! - I actually purchased the io 9 series on desertcart almost a month ago. I'm not happy I purchased it day's before it went on sale. It's whatever.. Honestly I have to say this toothbrush is absolutely no joke and worth every dollar I paid. The io series is great I went with the io9 series because it comes with 4 brush heads that's good for around a year or more depending on how you use them . Also the lcd screen Honestly not necessary but I love it.. Most important the performance. This toothbrush cleans better than my dentist has ... My teeth get whiter on every use even while I'm using mouth freshener paste. I can only imagine if I try out some heavy grit whitner paste. Also I'm using it on daily clean not the highest level. It's an amazing toothbrush. If the battery dies it has a 2 year warranty or you can just buy a better 14500 battery Oral-B built this unit to be easy to service. As far as mold building up that's not happening with me. I use warm water to rinse out the brush head and main unit. I almost didn't purchase this because of people talking about mold build up! Smh . Honestly rinse it off as you would any tooth brush and dry it off and also let it air out & charge in a dry area. Please do not stick sharp things like picks in the top of the brush handle. There is a rubber seal that protects water from getting into the electronics and if you poke at it black stuff will come out because the seal is made out of black rubber! I will update this review if there are any issue's. If this is all your seeing know I'm a very happy customer and it's working 💪! I do not like I paid much more than the current sale price is but it's whatever...

### ⭐⭐⭐⭐⭐ Excellent clean and great build quality!
*by R***S on October 15, 2025*

I have always used Sonicare electric toothbrushes, and have had many models over the years. I've owned several of the DiamondClean models and most recently the Prestige 9900. I have enjoyed them overall but have been frustrated with how quickly they wear out and break. Most recently when my Prestige broke, I wasn't looking forward to buying the same model twice. I decided to try out the Oral B iO Series 9 instead, and am very happy with the change! It doesn't feel as drastically different from the Sonicare as I expected. The round head is easy to use and comfortable. The sonic vibration is strong but quiet. I feel a very deep, thorough, and refreshing clean with this brush. To me it is as good as the best of Sonicare, but probably not significantly better. The only thing I prefer about the Sonicare so far is the aesthetic and hand feel. Sonicare premium models look and feel luxurious. The Oral B is well-made, but a little bulky and utilitarian. Not a big deal, it's a toothbrush. Time will tell if it lasts any longer than Sonicares do! So far so good.
