Smart 6 6000 vs Genius 9000 One of the biggest differences is that the Pro 2 2000, which is the more premium model offers an extra cleaning mode. Ultimately, all of the brushes will provide a very good clean to the teeth and gums if used correctly.

Below, is a list of models we have compared to one another, plus some that we have compared to their Sonicare equivalents. 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. Smaller and less unsightly, it is designed to sit on a worktop rather than adhere to a wall or mirror. You just need to pop your phone in it, which takes a couple of seconds compared to the tens of seconds with the Genius brush configuration. You phone then sits in portrait or landscape orientation and shows the on-screen timer.

The great number of choices you have within the Oral-B range can make it really quite difficult to decide which toothbrush is right for you.

The Oral-B Pro 2 2000 has 2 cleaning modes, the Pro 3 3000 has 3 cleaning modes, the Smart 5 5000 has 5 cleaning modes, so as you would imagine the Smart 4 has 3 cleaning modes….Yes, I know, I can’t quite figure that out either.

It is a little harsher/aggressive feeling than a Sonicare or Colgate brush. Whilst this is not exactly the best way of rating a clean of the teeth, it really feels like it has done something.
