Brush strokes per minute

As one of Sonicare’s most advanced electric toothbrushes, the DiamondClean uses up to 31,000 brush strokes per minute to maximize cleaning. As a result, the brush drives fluid between the teeth—known as “non-contact” brushing. This means that the Sonicare DiamondClean can efficiently target all areas of the mouth.

Brushing mode

Like many Sonicare models, the DiamondClean toothbrush has multiple settings. These include: Clean, Deep Clean, Whiten, Gum Care, and Sensitive. Importantly, this brush appeals to a wide market due to its adaptability to a range of dental problem areas.


In contrast to manual brushes, the Sonicare DiamondClean has a Smartimer, which times your brushing routine for the recommended 2 minutes. With most Americans brushing for 45 seconds on average, the Smartimer ensures that users reach the advised cleaning time to improve overall dental hygiene.


Along with the Smartimer, the Sonicare DiamondClean toothbrush also pauses in 30-second intervals to remind users to move on to the next section—or quadrant—of the mouth. Significantly, this ensures an even clean and helps users to maintain a consistent brushing routine.

The quadrant of the mouth are as follows:

  1. Top teeth: back left to center
  2. Top teeth: back right to center
  3. Bottom teeth: back left to center
  4. Bottom teeth back right to center

Battery life

Because of its 3-week battery life, this Sonicare DiamondClean is ideal for people on-the-go and is more eco-friendly than many other models. In contrast to competitors such as Oral-B (whose brushes have a battery life of around 10 days), the DiamondClean is a long-lasting and reliable toothbrush model that minimizes the necessary charging time.


A unique selling point of the Sonicare DiamondClean is its specially-designed travel charger which acts as a travel case. The case comes with a USB port so you can charge your toothbrush on the go and store it safely. Helpfully, this eliminates unnecessary packaging and has been designed with your busy lifestyle in mind.

Brush head replacements

The Sonicare DiamondClean toothbrush includes 3 brush heads: the DiamondClean, InterCare, and the AdaptiveClean. The DiamondClean is highly rated for its ability to whiten teeth (and therefore works well on the “whitening” mode) while the AdaptiveClean is best used for everyday and deep cleaning as it closely targets the tooth surface and gum line.

How does the Sonicare DiamondClean compare?

Who is the Sonicare DiamondClean suitable for?

  • People seeking advanced brushing modes.
  • Those used to electric toothbrushes.
  • Those with particular problem areas that would benefit from the DiamondClean.

With this in mind, this product is less suitable for people looking for everyday cleaning without additional settings. This is because the DiamondClean is a larger investment than most other models, and a toothbrush with a one-mode setting, such as EasyClean, would likely be more cost-effective. Along with this, the DiamondClean is less suited to those who are new to electric brushes.

Reliability and long term use

Although Sonicare has a good short term battery life, its long-term efficiency is criticized because most brushes tend to last 2 years maximum. Despite this, many still use Sonicare products because of its reputable status amongst dental professionals.

It is important to remember that using Sonicare products properly is crucial for long-lasting brushes. In fact, Sonicare suggests charging the brush for 24 hours prior to first using, and to also avoid charging the brush constantly afterwards.


As an advanced Sonicare brush model, the DiamondClean offers a range of brushing modes that are suited to those with sensitivity or other problem areas. Along with this, the brush heads can effectively remove up to 10x more plaque than a manual brush. So, for those seeking customizable brushing, the DiamondClean is a great investment.
