Q: How many brush strokes a minute does it have? 62000 or 31000?

A: 1 brush STROKE (an up and down motion) = 2 brush MOVEMENTS (one up, one down) And that means … 31,000 brush-STROKES-per-minute = 62,000 brush-MOVEMENTS-per-minute. They describe the same rate of speed (frequency). So, there’s nothing new and improved here. Both brushing action descriptions are equivalents.

Q: I purchased the 4100 in Jan. -6months ago. I’m seeing black oily substance underneath the brush head, it seems louder recently, & brushing strength seems less now. Could oil be coming from inside base & am I covered for replacement?

A: Hi there. Thank you for bringing this to our attention. We'd like to assist you further regarding this matter. Please leave us a private message on Facebook or call us at 1-800-682-7664. We are open from Monday - Sunday 9:00 AM - 6:00 PM EST. Talk to you soon!

Q: What size replacement brushes work with this model? Will C1 work?

A: Actually, the former answer "it uses a C3 head" is belied by the company provided photo showing a C2 head. What the little "radar" symbol means, sort of like my computers WiFi presence symbol, is not stated. Looking further, that seems to be the Brush Sync chip symbol, to activate the LED light that it's time to change the brush head. Your handle may not have that capacity, but all brush heads C1, C2, and C3 will work in the handle

Q: How many replacement heads do you get?

A: It only comes with one, but replacements are not expensive and you need them every six months or as needed.

Q: Can I purchase new brush heads for this toothbrush ?

A: Hello! Yes, the Sonicare brush heads for Sonicare Series 4100 Toothbrush are available to purchase. Also, here are the brush heads that are compatible with the toothbrush HX3681/24: W/W2 HX6062/65, W3 HX9064/65, C1 HX6015/03, C2 HX9023/65, C3 HX9044/65, G2 HX9033/65, G3 HX9054/65, and S HX6053/64.

Q: Is this product dual voltage?

A: Hello! Kindly charge the Philips Sonicare 4100 Toothbrush HX3681/24 only with Philips WAA1001, WAA2001, UL or equivalent safety approved adapters with input ratings (100 - 240V~; 50/60Hz; 3.5W) and output ratings (5Vdc; 2.5W).
