## Description

Achieve better plaque removal than with a manual toothbrush thanks to the Philips Sonicare 1100 Series sonic toothbrush paired with the C1 Simply Clean electric toothbrush head. Enjoy a powerful yet gentle clean, even in those hard-to-reach areas. The Advanced Sonic Technology provides gentle yet effective cleaning, pulsing fluid between teeth and along the gumline. To help you get used to the Sonicare experience, the EasyStart feature adjusts the power level of the toothbrush over the first 14 uses. Improve your brushing technique with QuadPacer, which reminds you to brush each section of your mouth for 30 seconds, and reach your recommended brushing time of 2 minutes with SmarTimer. Experience up to 14 days of regular brushing after a single charge, bringing a new level of convenience to your brushing routine (based on two periods of two-minute brushings per day on standard mode). Dental professionals recommend changing brush heads every 3 months.

Review: Good quality, affordable leice - Really good and doing the work so far. I’ve got it around 3 months ago and it’s still going great. The price is very affordable and the quality is good.
Review: Very good toothbrush. - It's just good, plain and simple. Not gonna rant in this one like I do in other reviews, it's a toothbrush, you know what it does. This has great battery life, I charge it maybe once every two weeks, it cleans good, replacement heads are a bit expensive but you don't need to replace them often, so. Wish it was a bit wider at the base, as if it's not on the charging stand it falls over from a mosquito fart.

## Questions & Answers

**Q: This 1100 model has a single intensity.  Is the intensity of the 1100 equivalent to the higher or lower intensity of the 2100?**
A: I'm not 100% sure, but I have had 2 other Sonicare higher end models before the 1100 and the 1100 is just as intense as far as I can tell.  It is my favorite one so far because it does the job, is lighter and smaller in diameter and costs much less.

**Q: I was sent model hx364w3 not ‎HX3641/02. mine is very weak. does it get as strong as older models after beginners mode?**
A: You can disable the beginner's mode by placing it on the charger then holding the Power button until it beeps.  (See manual for explanation)

**Q: Does this take the same head pieces as aquasonic black series ultra whitening toothbrush?**
A: I'm not too sure. I bought OralClass Replacement Toothbrush Heads for Philips Sonicare, Medium to Soft Electric Brush Head Refills for Sonic Care DiamondClean C1 C2 C3 G2 G3 W2 W3 4100 5100 6100 HX6250 etc, 8 Pack. If yours is not listed I'm not too sure of purchasing these.

**Q: Do you not brush hard like a manual?**
A: I find that I do not brush as hard as with  a manual.

### ⭐⭐⭐⭐⭐ Very good toothbrush.

### ⭐⭐⭐⭐⭐ Thumbs Up Results, Easy for Travel
*by S***S on January 4, 2026*

I replaced a Sonicare from 2009 with this one and it’s A++. After I got this toothbrush, my dentist complimented my gums. It holds a charge for what feels like forever, but it probably at least a month. It’s streamlined and I can travel easily with it. Especially for the price, it was well worth it.
