My Phillips sonicare diamond clean has a charging cup and travel case! I’ve had it a few years now and I love it (it’s [this one](https://www.target.com/p/philips-sonicare-diamondclean-smart-9300-electric-toothbrush/-/A-91735623?preselect=89376318#lnk=sametab), I got mine at Costco). I have a similar problem bathroom and my personal rec would be to put the charger in another room (bedroom on a dresser works well!). This keeps it away from the toilet but removes the possibility of mold growth from keeping it in an enclosed space. The cup is dishwasher safe and I find it keeps any drips contained well!

I love the deep clean mode they have on the 9300 models and above. That said, the 7500 series has the same deep clean but they only trigger it for the last 30 seconds of a 2 minute brush cycle, it's literally a paywall. For that reason, I do really like the DiamondClean series, but heavy asterisk!

go for [Philips Sonicare ](https://www.reddit.com/r/recsmatter/comments/1pswa4s/philips_sonicare_diamondclean_smart_9300_premium/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)rather than Oral-B many people prefer philips sonicare over oral b because the sonic vibration action feels gentler on gums while still removing more plaque than a manual brush sonicare tends to be better on the gums and generally more thorough, while oral b sometimes feels more intense but isnt always as comfortable for daily use.

näin necrobump niin io sarjasta 6 on se kultainen keskitie hinnan ja ominaisuuksien näkökulmasta, saat suurimmanosan lippulaivamallin ominaisuuksista mutta ilman isoa hintaa. isoin hyöty jos hyppää 9 on että saat 3d seurannan harjaamiseen 6 vyöhykkeen sijaan.

Oral B makes a good option too. I personally use the cheapest sonicare Diamond clean, mostly because the higher end models just have additional settings I never use. The cheapest model comes with 2 speeds (I use the higher speed) and some other shit I don't care about.

I had the Rolls Royce Sonicare that was like $200 and it broke just like you said within a couple years. Replaced it with the $60 version and it’s lasted way longer. Dentist said those super expensive ones are just so rich people can feel like they’re doing a better job than most.  I also changed how I brush. I used to press down pretty hard and go back and forth super fast like I would with a manual toothbrush. Started just moving slowly over the teeth with medium pressure at most, and I think that has contributed to the longevity as well.
