Customers are saying

Customers praise the Power Flosser & Toothbrush System 7000, HX3921 for its multiple cleaning modes and intensity levels, long battery life, ease of use, and overall design. The water pressure is adequate for most, and the SoniCare app is comparable to the Oral-B app. However, some customers have expressed concern over the fact that only one brush head is provided with the system.

    I recommend this power flosser for the best hygiene! You can set the flossing modes that will best suit your needs. Our annual dental visits have even better results from using this flosser with our Sonicare toothbrush! Saves time and money on dental visits. Worth the expense and highly recommend this for your household.

    A great 2-1 combo as it not only charges your toothbrush but also has a decently sized resivor for the water floss. I do wish the floss was more powerful though as there are times which I end up flossing afterwards.

    Doesn't take much space on the counter and definitely better than a regular toothbrush. Has a lot of features i probably wont use anytime soon but worth having just in case. Been using for about a month now can't say anything negative so far.

    Excellent Water Floss and Toothbrush Combo!

    I am a first time user of any type of water flossing device and I have to say, I’m kind of hooked. I really wish I would have begun using something like this years ago. I’ll say there was a bit of a learning curve. My first few uses I felt like I was spraying more water outside my mouth than in. So if this is you, don’t give up. With a few uses I figured out the proper mechanics and it has been a breeze since. There are several settings and tips, each designed for a particular use. If you are a novice such as myself, I would suggest starting out on the lower intensity first, otherwise you may find yourself covering the sink, floor, and mirror with water. Ask me how I know. Once you figure out how to use it, definitely increase the intensity. The handle is held magnetically to the base which is super convenient, and the cord automatically curls back into a recessed storage area. They’ve really thought of everything and the design is amazing. It actually looks great on our sink and I’ve had a few positive comments about it from friends. This is actually kind of fun to use, and as crazy as it sounds, I look forward to using it. My teeth and gums feel clean and refreshed. I was really surprised at how well this works, and how much more it cleans around the gum line. I have rather sensitive teeth and even on the most intense settings there was no discomfort. The interchangeable heads are easy to switch, and there is a nice hard shell case to store them in. Also included is a very nice hard shell travel case for the rechargeable toothbrush. As for the toothbrush, hands down the best I’ve ever used. The first charge took several hours, in fact I wasn’t sure it was charging at first. Once the initial charge was complete I’ve had no issues with charging. The battery is solid and there is an indicator on the brush that displays the charge level. There is also a very small flashing indicator light for charging which I missed at first. Also included is a brush cover that clips onto the brush head when not in use. Like I said, they’ve really thought of everything. The toothbrush is super comfortable, powerful, and really cleans. The brush heads can be easily changed, but are solidly connected to the handle. When you are done brushing, it sits nicely on the charging stand which is connected to the water floss base. And just like the water floss, this is a really nice looking toothbrush. Overall everything is well designed, with a solid build and great aesthetics. Performance is amazing, and the thought out into both the water flosser, and the toothbrush shows. I would highly recommend this to anyone in the market.

    This product helps to remove food particles trapped between teeth . The results will be less plaque if any buildup, and fresher smelling breath!

    This set was nice while it was working, i bought it under totaltech and thought id be alright just for the base to start leaking a month out of the total tech coverage and the toothbrush itself to outright die and refuse to charge or turn on a few months later. Stay away and go with oral B

    Best Flosser on the market + ideal toothbrush

    I've been using Philips Sonicare toothbrushes for a number of years now, and I won't spend a ton of time in my review on the toothbrush itself. This product is set up just like I would expect from any other Sonicare product. The integration of the base for the flosser and the toothbrush charger is a nice feature, and it saves space on the counter. I mention this because you won't have any choice but to put it on the counter - it takes up some substantial room! After having previously used a Waterpik flosser that was a little messy, this is a nice change of pace. Philips has applied the same idea with the changeable toothbrush heads to their flossing system, and the tips are replaceable. The handle of the flosser is the same form factor as the tooth brushes and the water tube is self retracting nicely into the base. It's also long enough to give you some working room when you want to floss, even though you won't want to wander far from the sink anyway while you're using one of these. Multiple cleaning modes and pulsing to the water stream serve similar functions as the toothbrushing letting you know when it's time to change sides. Of course refilling the tank is dependant upon how often and for how long you use the flosser, but during my first few weeks I got at least 3 days out of each fill before I had to refill it. None of the modes are painful on my gums, and the deep clean feels like it is making a difference on my teeth and gums. The added inclusion of the Sonicare toothbrush as well really tops this one off. The included brush has the 3 modes - Clean, Deep Clean and Gums, and it's compatible with the wide range of Sonicare heads as well. This is the brush that I had already replaced most of my family's with (or one similar) and I loved that there is a charger for it on the base of the flosser. Overall this is well made, and garners the room that it takes up on the counter. I love being able to answer "YES!" when the hygienist asks me if I've finally gotten around to flossing...

    I’ve been using Phillips toothbrushes for several years now. Their electric toothbrushes are modernly stylish, easy to use, travel easy, and most importantly, make my mouth feel clean. With the addition of the power flosser I’m more inclined to floss after I brush instead of using my normal disposable single use floss picks. The toothbrush has 3 different cleaning modes. Clean, deep clean+, and gum health. Each brush mode has gyrates at a different pace and length of time to clean your teeth and gums. The brush head that came with the brush along with the different modes, do a really good job at leaving your mouth feeling clean and refreshed. You can also adjust the intensity but based on your brush and cleaning mode, it will automatically select the best mode for you. I brushed mostly on the high intensity for the best clean. As for the brush head it did a really good job at making my mouth and teeth feel clean when I was done brushing. No complaints with the brush or the function. While we’re on the topic of the brush, in the box you get a stand alone charger as well as a travel case. The case and charger color match your brush color and the white brush looks very “crisp” and modern. The power flosser also includes a spot for the brush to sit so you can keep it all together. I just threw my standalone charger in my travel bag just in case, but using a previous version of Sonicare, I’ve spent 3-4 days without needing to charge my brush. I would expect the same from this one. Finally you can use the Sonicare app and connect to the toothbrush to give feedback on statistics such as how often you brush, how long you brush and you can connect it to your apple health app if your into that stuff. I’m don’t expect myself to use this information that often but It’s good to know I have it. The power flosser is the real selling point of this kit. I admittingly do not floss as much as I know I should, and my dentist knows that too. The power flosser makes me want to floss right after brushing. Setup is easy. Place the water reservoir on the base, fill the reservoir up with warm water. If your teeth are sensitive, keep in mind that you’ll be blasting them with whatever temperature water you put in the reservoir. Next select the floss head you want to use. The Philips website speaks highly of the “+” pattern head but the regular floss head was my preference. The head snaps in one way. Hit the power button on the base unit and use the switch on the wand to start/stop the flow of water. Upon first use you want to start with low intensity and work your way up. If your gums are sensitive or you haven’t flossed in a while, higher intensities will likely make your gums bleed. I have pretty sensitive gums so I started low and worked my way up. Working the pick around and between my teeth, I found that getting too close stalls the pump so it took a bit of trial and error to find the perfect distance. I can also tell you accidently taking it out of your mouth without turning it off first will blast water at high speeds everywhere! I didn’t have any issues running out of water. In fact, I usually empty mine and use fresh warm water every time because my teeth are a bit sensitive to temperature. The hose is plenty long enough for my setup and the magnetic holder is a nice touch. I felt like the power flosser did a good job at removing debris and cleaning between my teeth. I do have my wisdom teeth and it is a bit harder to get between them but then again, so is food. I know that I’m going to floss more often just because of the convenience and ease of use and how available it is right next to my toothbrush. If I could throw a few recommendations at the next version it would be to increase the height a bit and reduce the length. I find that for my sink real estate, it takes up just a bit too much room. This may not be an issue for most but I had to make room. Small price to pay for healthy oral hygiene.
