The Oral-B Genius Pro 8000 earned the highest score out of all the models we looked at, earning it an Editors' Choice award. This model has superior cleaning power and is very easy to use. In addition, this model can connect to your smartphone to help you track your brushing trends and ensure you aren't missing anywhere while you brush. Unfortunately, this model wasn't the most comfortable — especially for those with smaller mouths or sensitive gums — and we weren't enamored with the position sensing aspect of the mobile app. All in all, this is a great electric toothbrush for those that want the best cleaning performance, and don't mind the premium price tag and more aggressive brush head.

Our Analysis and Test Results
The Pro 8000 received the highest score in our cleaning and ease of use tests, propelling this model to win it Editors' Choice Award. This model has a rotation-oscillation style toothbrush head, similar to the other Oral-B models. This style of brush has always scored very well in our cleaning test, but it can be a little rough on your gums and isn't very comfortable. Some of our testers that have more sensitive gums declined to continue using this model after the first go, citing too much gum discomfort.
We spent over 120 hours testing these products to determine which ones were worthy of awards. The Pro 8000 was the top performer overall, but you can see how the rest of the models ranked in the chart below:
We split our testing process into four weighted metrics, conducting over a dozen individual tests to determine scores. Each model received a score for each metric, which was then aggregated into the overall score. We detail how the Pro 8000 did in each metric in the following sections, looking at what it did well and where it fell a little flat.
Our highest weighted metric and the one that comes to mind first and foremost when thinking of these products is cleaning performance. This metric made up 45% of the total score and consisted of two separate tests: plaque removal and whitening. The Oral-B Pro 8000 did very well in this test, tying for the top score with a 9 out of 10. You can see how the other models ranked in the chart below.
Our plaque removal test consisted of having a panel of testers wait at least 12 hours since they last brushed their pearly whites, consuming as much sugary food as they could over that span of time. Each tester then used a plaque disclosing tablets per the manufacturer's instructions, nicely staining the accumulated plaque from eating all of those donuts bright pink. They then brushed with the Pro 8000 for two minutes, and we compared the results with before and after photos.
This model removed almost all the visible stained plaque for every single one of our testers and was either the most effective toothbrush, or second-most effective toothbrush for each of them. Our panel had mixed genders and ages, and the only common issue with this brush was the difficulty to reach the molars furthest back for those that had more petite mouths. These scores were all based on the first or second time for each of the panel using this brush, meaning that it was exceptionally easy to clean all of your teeth, as they had no experience with this brush and no preconceived plan to pay attention to trouble spots.
To test the surface stain removal ability, we stained eggshells in coffee for four days and then ran the toothbrush over a tooth-sized area for a full, 120-second cycle. This is roughly equivalent to the amount of brushing that a single tooth would see over a four week period. This model scored the same as the other Oral-B's, unsurprising, as they all have practically identical brush heads.
Comfort can be almost as significant of a metric as cleaning performance, as an uncomfortable toothbrush can make your teeth cleaning experience so unpleasant that you won't want to use it. Regardless of how well your electric toothbrush cleans, it won't make a shred of difference to your dental hygiene if you don't use it. We rated these products on how comfortable they were to hold, how comfortable they were to brush with, and how loud each model was. The Oral-B Pro 8000 didn't so the best in the metric, earning one of the lower scores with a 4 out of 10. You can see how this model compared to the other models in the graphic below.
This model felt great to hold in your hand but had some severe drawbacks when it came to brushing. The rotation-oscillation brush head does a fantastic job of cleaning, but it was exceptionally rough on the gums. One of our testers with more sensitive gums had to quit using it, as his gums were in excruciating pain — even using the brush in its most sensitive mode. Other testers, especially those with smaller mouths noticed that this brush head was much more uncomfortable when brushing the back molars, mainly due to it being approximately 33% deeper than the side-to-side style brush head.
This model was also on the noisier side, measuring in at 78 dBa taken 2" away from the mouth when brushing. Testers also noted that this brush sounded louder and more mechanical when being used, compared to the softer buzzing from the side-to-side models.
Ease of Use
The technology behind electric toothbrushes has improved to the point where these products are packed full of various features and functions. We assessed how easy it was to use these products, basing our scores on their visual appeal, their interface, on and off-base stability, how easy it was to clean the brush, and the number of brushing modes available. The Pro 8000 scored exceptionally well, tying for the top score in this metric with a 7 out of 10. The following chart shows how the other models stacked up.
This model was well-received by our panel when it came to aesthetic appeal, appreciating the sleek exterior and the easy to understand icons on the front of the brush.
These icons show the different brushing modes, which this brush has six — Daily Clean, Pro Clean, Sensitive, 3D White, Gum Care, and Tongue Clean. This also made it very clear which brushing mode you were using, and the interface to switch between them was very easy to operate. The Pro 8000 also has a two-minute timer, buzzing every 30 seconds to alert you to move onto the next quadrant of your teeth.
This toothbrush was very stable off of its base, with almost every other toothbrush toppling before this one. However, it was much less stable on the base — the larger toothbrush on the small base made it top heavy and easily tumbled. This model also includes a charging travel case.
This drastically changed when the extra brush holder was installed on the base, making it almost impossible to tip over. One of our only issues with this model in terms of ease of use was the new position sensing feature.
We didn't find this to be the most accurate, with the app mistaking what section of the mouth we were brushing at the time on a frequent basis. We did like that the app still had all of the features of the Pro 5000 — like the progress badges and brushing personalization.
Our final metric was a battery test, where we compared how long each brush lasted on a full charge, the quality of the battery indicator, and whether or not it had any sort of low battery warning. The Pro 8000 had an average battery life, earning it a 5 out of 10. This model lasted for 70 minutes of brushing — equivalent to 17 days of normal use for a single person. You can see how this compares to the other models in the chart below.
This model had a typical battery indicator, similar to the Pro 5000. It consists of a battery silhouette with three bars inside to signify the charge level. This model also has a flashing red light to indicate when the battery is critically low.
This model is a little on the pricey side but it received the top score out of all the models we tested. In this case, you need to pay to get the best!
The Pro 8000 tied for the best cleaning performance of the group and was very easy to use. This model can even be too much cleaning power for those with sensitive gums and can be a little awkward to brush with for those with more petite mouths, but all in all, this is a fantastic toothbrush.
