The variant with the case is primarily sold via Shaver Shop for the same price as the one without a case. When using the Bluetooth connectivity, the app will show the cleaning mode. I will explain the connectivity option in more detail shortly. Using a free app available for Android and iOS you can connect the 4000 wirelessly to your smartphone. The idea being, launch the Oral-B app, sit the phone in the stand and you can now see the timer and how well you are cleaning, plus all the useful advice. It has not been designed to be easily repaired by yourself. Trying to replace parts like the battery will likely break the brush. This makes it more likely to be discarded rather than repaired if broken.

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. There is the reality that most of us don’t need over a weeks battery life, but there is something to be said for having the ability to take a brush away on holiday and not having to worry about charging it!Each of the 3 cleaning modes work slightly differently, with differing levels of oscillations, rotations and pulsations to achieve different cleaning effects on the teeth. You should spend 30 seconds cleaning each section. The pacer helps you keep an even brushing time on these 4 sections. I think this is a big oversight and even if it meant a few extra pounds being added to the price, I think it would have been a worthwhile addition. Some Sonicare and Colgate models do actually achieve up to 3 weeks, but Oral-B are now much much closer in their capabilities.

Just relieve the pressure and the light will go out and the motor power up again. Just remember to let the bristles essentially glide across the tooth surfaces. The first and most obvious difference between these 2 brushes is the handle design. They are similar, but different.

Prices will vary from store to store. Quite often online retailers will have the best price, but promotions run by high street stores at certain times of the year will see them come inline or cheaper than other retailers. At the same time as the LED pressure sensor illuminates, you should also notice that the speed of the brush head will decrease and the sound of the motor will change. This is nothing to worry about. It is programmed to do this, until such time as the pressure is relieved. 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.
