It has 5 pressure settings. The 2nd setting is about equal pressure to my old very expensive "waterpik" brand water flosser. The "waterpik" unit looks very similar but didn't have enough pressure on the max setting to actually get debris from between my teeth. I've used the h2ofloss unit at the 4 setting and it works perfectly. I could always crank it up another spot if it didn't work. The flosser stopped working after 5 months due to airlock. I contacted the company via their e-mail: support@h2ofloss.com and received a reply the next day and had a replacement unit on my doorstep in two days. Amazing customer support!

I am very impressed with this water flosser! It is powerful, easy to use, and leaves my teeth feeling incredibly clean after every use. The different pressure modes make it perfect for sensitive gums as well as deep cleaning. I also love the large water tank and the variety of tips included for different dental needs.

The battery lasts a long time, and its portable design makes it great for both home and travel. The pink color is beautiful and the quality feels excellent. It has helped improve my oral hygiene and makes flossing much easier than traditional dental floss.

After my last visit to the dentist (had not been in several years) I started to think about using a water-pic type device since that's what the dentists use to blast the plaque off your teeth these days - very little use of the old metal dental picks and the scraping away of the plaque.

Had never used a water-pic before but a long time user of floss. Looking on Amazon for ideas found out there are battery powered ones that incorporate a water tank and don't require any hook up to a faucet. Selected this H2O model based on reviews and price.

Amazing difference using a water jet to clean between teeth vs. floss - much, much more effective (why doesn't the dentist recommend using a water-pic)? The amount of debris that comes out while using will astound you - it did me and my wife.

This unit is very effective and easy to use; the adjustability of the nozzle direction makes it easy to accommodate access, the adjustable frequency of the water pulses lets one tune it just for your comfort (believe me, when you first use it you will need that lowest setting), and the capacity of the water tank.

At first, it would take 3-4 tanks to do the cleaning but now I can be finished after 1 1/2 tanks and the second to highest pulse setting - very quick and effective.

We took this unit on our vacation and it worked fine but make sure you have a USB 5v power supply somewhere in your travel items. Once you get used to the super clean feeling in your mouth after use you will not want to be anywhere without access to this device on a daily (bi-daily) basis.

Only negative on this product was the breakage on the two plastic tabs molded into the tank that help retain it to the water jet body. These are pretty flimsy and I knew it wouldn't be long before they broke allowing the tank to come free when loaded with water. Solved this very easily (for us) with the use of a stout rubber band going around the bottom of the tank and resting on the chrome button that releases the water nozzle. Works great, easy to do, and no waiting for the manufacturer to come up with an improved tank or a replacement.

First time user tips - 1) Use the lowest setting on the strength of pulses until your mouth/gums get a chance to adapt, 2) use warm water at first for best comfort, and 3) adjust your grip on the unit so that you don't (and you will at first) inadvertently hit the button to speed up the pulse frequency - your gums will not appreciate the increased intensity.

Final note: will never be without a water pic again for dental hygiene.

11/20/20 Update to original review

This is a further evaluation and commentary on the use and reliability of the H2o flosser (model IPX7) that I purchased in March of 2020. There have been problems, the most important one has been highly satisfactorily resolved by the H2o support team.

My first unit worked flawlessly from purchase until the first problem prevented it’s use in late August. At that time, the unit began to deliver less water flow at the nozzle – it was a mixture of air and water (compared to water only as the unit originally operated); this stream was not effective in cleansing the teeth and gums.

I contacted H2o customer service and they (specifically Lily Lange) responded immediately by sending out a replacement; I received that unit within a week of my original email describing my problem.

Unfortunately, within two weeks the replacement unit malfunctioned in that it too began delivering a weaker water and air mix and would not recharge. I tried several different USB 5v chargers with no improvement. I contacted Lily L. again and within 3 days I had another replacement flosser in my possession.

Happy to have another flosser (once you began using a water jet flosser any other means of cleaning your teeth are woefully inadequate IMHO) I astoundingly was confronted with the very same – won’t take a charge – problem within 4 days.

What gives, I asked myself...tried other chargers that I knew were effective to no avail and began to think that maybe the H2o flosser was just not going to work out. However, I had purchased another flosser when my wife and I decided we couldn’t share (going out of town apart and being without said flosser – no way). Purchased hers in late August and it has been working without any problems.

Again, got back with H2o customer support and they posited a potential problem – the power cord from the 5v charger to the flosser. Then some lights began to come on in my head; back in July when we vacationed out of town I noted that the I was having some kind of electrical connection problems in that I could not get a solid connection to the flosser with the cable. The blue light, indicating a connection, would sometimes not go on and stay on; I played with the connection until it was solid and had to sometimes lay the device a certain way to maintain the connection. Also, the unit would still be flashing that blue light even after an all-night connection and I wondered whether something was wrong with the charging circuit in the unit.

When we got home the problem persisted and I, thinking that water in the charging port might be a problem, consistently put the little white plug back in the port during usage to discourage this potential problem. But, as I mentioned, that first flosser finally exhibited a problem I couldn’t work around when it began to deliver a weaker stream of water at the nozzle and requested a replacement unit (back in Sept.)

Now, with a first and then second replacement flosser not getting charged properly and H2o support suggesting that the cable might be the problem I used my wife’s cable to charge (again, hers had been working fine since Aug.); lo and behold the intermittent charging light problem was gone AND the unit fully recharged in less than 5 hours (H2o notes that a completely discharged unit may take up to 5 hours to recharge).

What further adds to the “strangeness” of my problem was that I also tried a “new” never been used charging cable that came with the replacement unit and it too exhibited the same problem. However, comparing the “bad” cables to my wife’s “good” cable showed a subtle difference that indicates some processing or design change was made to “said” cable. The photo shows the only obvious difference in the two – the “strain relief” feature on the two cables is different, the longer strain relief is on the “good” cable.

All normal indications for the recharge function appeared correct – the blue charging light was flashing indicating a solid connection. However, it appears that the “bad” cable could not deliver enough juice or power to recharge the batteries – only enough to energize the recharge circuit status (blue) light and therein lay the problem. This weak or partial connection also explains why the flashing blue light never went off even after being left on the 5v charger overnight.

Thus, as of this note, the 2nd replacement unit is working flawlessly AND the 1st replacement unit’s problem (weak and low volume water flow) was also corrected by a complete recharge courtesy of the “good” power cable.

As a final note, H2o send me another charging cable and I did not have to send back the defective first flosser or the faulty cables even though I would willing have done so.

I think the flosser is a great product for oral hygiene and H2o is very customer-oriented in standing behind their product(s) with excellent customer service.

works GREAT. has good speed settings! it's so high powered i use it on a speed 2 out of 5 setting. It gets very powerful if you need it! Used it probably 10 times still haven't had to recharge it

I've been a buyer on Amazon for over 25 years and I have to say---the seller of this H20Floss is the best I've ever encountered! First off, the flosser is amazing! It works 10000x better than I expected--I really feel the cleanliness and freshness of my teeth after using it, much more so than regular floss--and it keeps its charge for nearly 3-4 weeks of twice daily use! This flosser also comes with a regular wall socket adapter so one can charge it easily in the wall rather than just via USB port!!! That is a VERY good thing! It charges in about 3-5 hours and after that, lasts for 3-4 weeks! WOW! It has several 'speeds' in which you can choose how strong you want the water floss to hit your teeth/gums and several different tips to reach in any area of your mouth! It even comes with a travel bag!!! :faints: And all for an incredibly unbeatable price!!!!! I truly can't say enough good things about this item--it works above and beyond what I expected and I expected a lot. :)

Now, the customer service! After 6 months, I received a kind email from the seller (H20floss) asking how the product was and if I had any questions or needed any help with the flosser!!! That is amazing on its own---that the seller cared enough AFTER SIX MONTHS to contact me, to make sure all was well!! Have you EVER had a seller do that for you? WOW! I didn't really have any issues at the time, but about 2 months later, (8 months after purchase), the flosser started to have a MINOR problem in that the tips were a bit difficult to get to remain in the unit. I thought I had the tip in securely but it would fly up when I turned on the flosser and spurt water everywhere. It wasn't a HUGE issue, but a bit annoying and I'd have to then make SURE the tips were inside the unit's head super securely to make sure this didn't happen often. So I remembered that email the seller sent me a couple months back and replied, explaining the minor problem but also that I loved their product and its results on my teeth/gums! Instantly, I mean within hours, the seller replied asking some questions to clarify the issue and then when I explained a bit more, they offered a refund or replacement!!!!!! :faints: I clearly love the item so I opted for the replacement, which arrived in 24 HOURS! :faints again: Finally, just yesterday, the seller emailed again, letting me know the item was delivered safely and that they hope I was satisfied with their product and customer service aftercare!!! Oh boy, am I ever! I still can't believe how incredibly generous, fast and kind this seller is! They really stand behind their product--which is amazing in itself, truly one of the best purchases I've made on Amazon, or anywhere---and they really care about their customers! In a scale of 1 - 10 stars, I give them a 15!!! Bravo, H20Floss!!! Your product and your care are both above and beyond!!!!!! AAAAAAAAAAAAAAAA+++++++++++ God bless you!!!!

Last waterpik stop working, it was excellent but this is the BEST waterpik flosser I’ve ever had. Worth the cost and does amazing for me as a person who must take care of my teeth. 100/100 The best money I’ve spent; also comes with several heads and a bag to put it in to travel with!!!! 🤗🤗🤗

Works good, but could be better.

I had an older one that was fantastic and lasted years, but it needed replacing. Got this new one and immediately NOT a fan of the slow ramp up. I get some people probably like it, but I wish there was a way to turn off the ramp up. I was willing to deal with it because the flosser does a great job, but then it died after 4 months. My old one lasted years, but this one stopped pumping. I hear the motor spin, no water comes out.

Minus one star for the ramp up, minus one star for only lasting 4 months.

I bought this product in December 2025. It is now June 2026 and I had decided to come on here and explain that the product had stopped working. I gave it a two out of five stars because of how long it lasted. Then Customer Service from this company saw my review and immediately responded and gave me a replacement. This is a great water pick and I use it every single day. It’s easy to use an easy to charge. I would highly recommend this company for its excellent customer service and excellent product.

Sehr geehrte Leserinnen und Leser,

heute möchte ich über meine Erfahrungen mit dem HF-6 Irrigator berichten. Als jemand, der großen Wert auf die Mundhygiene legt, habe ich mich für diesen Irrigator entschieden, um meine tägliche Zahnpflege zu verbessern. Obwohl der HF-6 Irrigator einige positive Merkmale aufweist, gibt es auch einige rutschige Eigenschaften, die ich erwähnen möchte.

Positiv anzumerken ist die Effektivität dieses Irrigators. Er bietet eine leistungsstarke Wasserstrahlung, die Plaque und Speisereste effektiv entfernt. Ich konnte ein deutliches Gefühl der Reinigung und Frische in meinem Mund spüren. Die verschiedenen Einstellungen erlauben eine Anpassung der Wasserintensität, um den individuellen Bedürfnissen gerecht zu werden.

Darüber hinaus ist der HF-6 Irrigator sehr vielseitig einsetzbar. Neben der Zahnreinigung kann er auch zur Reinigung von Zahnspangen oder Implantaten verwendet werden. Dies macht ihn zu einem praktischen Werkzeug für Menschen mit speziellen dentalen Bedürfnissen.

Jedoch gibt es auch einige rutschige Eigenschaften, die beachtet werden sollten. Erstens ist der HF-6 Irrigator relativ groß und sperrig. Dies kann beim Reisen oder bei begrenztem Stauraum ein Hindernis darstellen. Zweitens besteht das Risiko, dass der Wasserstrahl beim Gebrauch aus dem Mund spritzt und den umliegenden Bereich durchnässt. Eine gewisse Übung ist erforderlich, um dies zu vermeiden.

Ein weiteres rutschiges Merkmal betrifft die Qualität des Produkts. In einigen Fällen habe ich von Benutzern gehört, dass der Irrigator nach längerem Gebrauch an Leistung verliert oder undicht wird. Obwohl ich persönlich keine solchen Probleme hatte, ist es wichtig, die Haltbarkeit des HF-6 Irrigators im Auge zu behalten.

Zusammenfassend lässt sich sagen, dass der HF-6 Irrigator eine effektive und vielseitige Option für die Mundhygiene bietet. Er ermöglicht eine gründliche Reinigung und ist für verschiedene Bedürfnisse anpassbar. Jedoch sollte man sich der rutschigen Eigenschaften bewusst sein, wie der sperrigen Größe und der Möglichkeit von Spritzern. Darüber hinaus ist es wichtig, die Produktqualität im Auge zu behalten, um mögliche Probleme mit der Leistung oder Undichtigkeiten zu vermeiden.

Ich hoffe, dass dieser Erfahrungsbericht Ihnen bei Ihrer Entscheidung weiterhilft. Vielen Dank für Ihre Aufmerksamkeit.

Such a good purchase as it works really well.

Kötü yorum yapanları anlamış değilim dişeti hastalığımın tedavisini görüyorum yeniden diştaşı oluşmasını önlemek için aldım ip ve arayüz fırçası kullanmayı sevmiyorum ürün gayet başarılı bilindik markaları mı alsam diye düşünmüş ve tereddüt etmiştim bu üründen başta ama basınç kuvveti gayet yeterli 3den yukarı çıkamadım fiyat olarak umarım çok fazla yükseltmezler çünkü fiyat performans bir ürün ben çok memnunum düşünmeden alın ve dişlerinize iyi bakın.

Good item, fit for purpose.

Stopped working in about 2 months after the purchase, I do not recommend.
