The toothbrush itself does not directly indicate when the brush head needs to be changed. However, there are two ways to recognise a change in good time: Firstly, the brush head has indicator bristles that fade over time, making wear visible. Secondly, when using the Oral-B app, a notification can be sent when the brush head needs to be replaced. The recommendation is to replace the brush head approximately every three months or sooner if it is worn out.

The Oral-B Genius X is compatible with most previous Oral-B brushes, with the exception of those in the iO and Pulsonic ranges. The following brushes are compatible with the Genius X: - CrossAction - FlossAction - Precision Clean - 3D White - Sensitive Gum Care - Ortho - Dual Clean - Interproximal Clean - Precision Clean - TriZone - Interspace. These brushes fit all Oral-B rechargeable rotating/oscillating toothbrush handles, except for the iO and Pulsonic models.

Hello Vers0, unfortunately, the charger that came with mine is only specified for voltages of 200-240 Vac. Best regards, Beat

Hi - according to OralB, you can use it in countries with 110v (resp. it works with 110-240v) - so, you won't need a converter (only found in german on a quick google search:https://www.oralb.de/de-de/mundhygiene/warum-oral-b/fragen-antworten/nutzung-elektrische-zahnbuerste-im-ausland) ...but you will need a travel adapter, if you go to country with different than CH-plugs, i think. hope that helps and BR, have a good trip ;)
