@waiinleong3782 It varies between series. The models up to and including the 4100 series have brush speeds up to 31000 brush strokes per minute. The models above that offer up to 62000 brush strokes per minute.
I just got the 7900, but I don't see much about it online. Is it just the 7300 but with the extra whitening mode? It did come with 4 heads that all seem to be whitening, with a "W" on them, so it seems to be focused on whitening..
@JoeBob79569 It looks like the 7900 series may be exclusive to the UK. We're located in the US so we don't have access to that one, however, it looks like the 7900 comes with the 4 whitening heads you mentioned, the extra brushing mode of White+, and a toothbrush stand.
@@abtelectronics Yea, that sounds right. I got it from the UK, but I live in Ireland, and the 7900 isn't even shown on the Irish website, only the 7100 and 7300, so it seems to be _very_ specific to the UK.
Great comparison, especially the conclusion! Thank you!
Do they have the same brushing speed?
