The Pro 3 3000 has a slightly revised design. It looks a little cleaner. Unlike the 2000, it does not have a rubber grip that runs the length of the brush handle. Instead, the only grip on the front is the panel that contains the power button. The Smart 6’s brush head holder is a moulded piece of plastic that clips around the charging stand and offers up 2 prongs. The brush heads then sit on these. It keeps them upright and they do not touch, but they are not covered like they are with the compartment with the 9000, which can accommodate up to 4 brush heads. If you feel you won’t use it, you may want to consider if the Pro 3 3000 is for you, you will be paying for a feature you won’t necessarily use otherwise. With the Smart Coaching you get from Oral-B Smart 4, you will improve your brushing habits and your oral health.

There is no battery in the case, to charge the brush and anything connected via the USB cable the case has to be connected to mains power. A smaller, but relevant difference relating to the cleaning modes is that the motor in the Pro 2 2000 is a bit more powerful and actually offers more movements than the Pro 600.

The next big difference is the battery life. The Pro 2 2000 has over twice the usage time. The Pro 600 will operate for 28 minutes, which is 7 days of cleaning based on one user. However the Pro 2 will last for 66 minutes which is 16 days of usage time. Up to 100% more plaque removal and gently whitens your teeth starting from day 1 by removing surface stains Some Sonicare and Colgate models do actually achieve up to 3 weeks, but Oral-B are now much much closer in their capabilities.

This price does exclude the cost of water, toothpaste and electric to charge it. This price also works on some assumptions, but you get a rough idea. The Pro 3 3500 offers the features we regard as essential (a pressure sensor and a timer) at an affordable price. When you brush, sensors within the brush detect if you are applying too much force to your teeth. When it detects this, it activates the pressure sensor. On the subject of cleaning modes, the Genius 9000 has an extra brushing mode known as ‘Tongue Cleaning’ mode. This is a cycle that lasts for 20 seconds with 7300 oscillations and 30,000 pulsations and designed for as the name suggests, cleaning the tongue.Ideally, a way of selecting the mode prior to actually turning the brush on would be the solution. This is not available, not even on the premium Genius 9000 model. Oral-B Smart 4 4000 Electric Toothbrush Powered by Braun is clinically proven to remove 100% more plaque*. Its round head cleans better* for healthier gums. Oral-B is the #1 Toothbrush brand used by dentists worldwide. Aside from the aforementioned 2 brush heads, the Smart 4 comes with a brush head stand included in the box. This is a moulded piece of plastic that clips around the charging stand that is also provided.

In our testing, we were able to get 66 minutes of usage time from the rush, which equates to 16 days use. I am confident that the Genius X motor is more powerful. I think the Pro 5000 you might have has something in the region of 8,800 oscillations and either 20,000 or 40,000 pulsations. Put these two brushes side by side and the differences between them are much harder to tell, they look almost identical, however there are some subtle differences.

It does too come with a premium travel case, similar to that of the Genius X, which allows the brush to be charged whilst inside. However, like the X, this requires a separate proprietary power adapter.

For 99.9% of users there will be years of hassle free brushing, but should you be one of the 0.01% where inevitably something does go wrong, Oral-B do not leave you high and dry. However, for those who require more detail, we do have a number of comprehensive written comparisons. The very nature of being an electronic item with moving parts does indeed make the brush susceptible to failure. However, the reliability of Oral-B products tend to be very good. So, both models come with a place to store brush heads, but the compartment with the 9000 is better than the stand offered with the Smart 6.The idea behind this connectivity is to essentially be a little like having a dentist or hygienist looking over your shoulder saying good, bad, brush for longer, you missed a bit. It is about education for better cleaning rather than telling you that you have got it all wrong.
