Waterpik Anmeldelser 

It is clumsy to hold. Difficult to fill the water tank. The brushes are too soft. I am better at wishing dental oral wash vigorously in my mouth. I wouldn't recommend it, a waste of money.

Title: Failed twice in months – warranty process a nightmare

Two units failed in quick succession — first within 3 months, second within 6 months.

While within Amazon’s return window, the return was easy and efficient.

Once outside Amazon’s period and dealing directly with Waterpik (Church & Dwight), the warranty process became a months-long ordeal. I was told a replacement had been shipped and “returned to sender,” yet no tracking number, carrier details, or evidence of delivery attempt were ever provided — despite repeated requests and confirmed address details.

If you are outside Amazon’s return window, be aware: the warranty process is extremely frustrating and unresolved in my case after nearly 4 months of weekly emails.

I recently reached out to Waterpik regarding the end-of-life disposal of my device, specifically looking for a manufacturer reclamation program. In 2025, it is standard practice for competent electronics manufacturers to take responsibility for the hazardous materials (lithium-ion batteries) and precious metals they introduce into the market.

I was shocked when Waterpik customer support informed me that the company has no reclamation program and expects customers to simply offload this hazardous electronic waste onto their local municipalities.

This policy—or lack thereof—is not just disappointing; it is negligent. It signals a profound incompetence and ignorance at the senior leadership level regarding the circular economy and modern sustainability standards. While other companies (like Panasonic) are actively reclaiming materials to close the loop on production, Waterpik is operating on an outdated, lazy "take-make-waste" model that externalizes their pollution costs onto the public.

A water flosser may clean your teeth, but a company that refuses to clean up its own mess does not deserve your money. I urge consumers to withhold financial support from Waterpik until they take the consumer product lifecycle seriously and implement a responsible reclamation program.

Do not buy Waterpik flossers
They do not last long - maybe a year even with limited use . Motor fails.
Had experience and with more than one, after second and third you learn it’s no

$200+ flosser that is disposable outside of its 2yr warranty?

Hard to imagine that such devices that could easily be made with screws and water seals would instead be glued and plastic-welded closed. Contacted support, they ghosted me the moment I mentioned the model and the time I'd had it.

Avoid at all costs. Buy something actually cheap from China instead.

A première vue, malgré le prix vraiment exagéré de mon appareil Hydropulseur Ultra Plus WP-160, il faisait le travail : nettoyer les interstices entre les dents.
Mais le tuyau s'est percé et compte tenu que le tuyau est solidaire de la poignée, il fallait racheter l'ensemble de la pièce.
- la pièce n'est pas accessible sur le site de waterpik, malgré ce qui est écrit sur la notice relativement aux pièces détachées ;
- sur d'autres sites, elle coûte 33 €, soit 1 tiers du prix d'achat ce qui est vraiment exagéré ;
- ce n'est pas du tout conforme aux principes de réparabilité et de durabilité ;
- j'ai acheté la poignée du modèle antérieur sur un site, mais ça fuit également.
En conclusion, j'ai un appareil très cher que je ne peux utiliser car je ne trouve pas les pièces détachées et tout ça pour 100 €!!
et le service après-vente que j'ai contacté n'a été d'aucun utilité.

Waterpik Flosser Cordless unit - tip clicks in but then pops out under water pressure. Tried to contact customer service and went through all the options to press numbers. Ended up sitting on hold and finally gave up waiting.

I bought The Sonic 2.0 Waterpik less than 3 years ago. The brush stopped recharging and I reached out to the Waterpik company, as it is supposed to be under warranty as noted in the registration warranty I purchased less than 3 years ago. I was told the warranty does not apply because I don't have the original recipe, even though I have proof of registration with the date of purchase as confirmed by the Waterpik. This is unacceptable and unethical.

So sad, I bet I’ve had 4 or 5 over a five year period, all have failed in less than 6 months. I baby the unit, keep it clean, etc. just stops, either the brush or water flosser.

Ich habe mir bei Amazon die waterpik cordless "waterflosser"-Munddusche bestellt. Trotz intensivster Recherche (youtube-videos!!) und dem richtigen Equipment ist es mir nicht gelungen, den Akku aufzuladen. Ein Anruf beim Kundenservice waterpik Deutschland war absolut desaströs. Keine Infos, keine Ratschläge. Nur eine Aussage wurde übermittelt. Ich soll mich an Amazon wenden.

I have the WP-100 Waterpik, countertop flosser. Never again. The reservoir drips/pours water when removing from machine for refilling and replacing. A new 'valve' (sent from Waterpik) fixes it, for a couple of weeks. then have to keep calling to get new valvies. Waterpik evidently knows its a problem since their instructions say to call for free replacements when it fails. (How about designing a valve that doesn't fail?) I have replaced the valve and 2 weeks later it is dripping again. Over and over. Waterpik has a list of things to accuse the user of doing to escape responsibility for bad design (hard water?not cleaning with vinegar solution every few weeks? not emptying reservoir after every use (and then waiting for unit to re-prime itself after filling)? cleaning in dishwasher?, etc. etc.) I had an older version of this Waterpik for years without having this issue. No more Waterpik for me.

I have had 2 waterpik cordless in the past 2 years. I dropped the first - on a carpet! - a fall of about 3 feet and it stopped working. Yesterday the replacement rolled from the side of a sink into the sink basin - and promptly stopped working. Pretty shoddy and not what i would expect for the kind of money each cost. I did not retain receipts (who does after 6 months?) and so can not claim. But twice bitten,. definitely now shy and will look elsewhere for a different brand

I got this as a promo from my dentist (Deep clean special with this waterpik brush and cleaning set). It was DOA and waterpik would not honor their warranty saying I must have an invoice showing the purchase with the serial number. I do have a dentist invoice showing it was a recent promo but I guess it’s not good enough for waterpik. I asked my dentist whether they make the receipt but she said it was part of a joint promotion so these are directly from waterpik. I guess waterpik wanted to promote their product with the dentists, but surely they got what they wanted. THE WORST REPUTATION.

I bought a Waterpik Complete Care 5.0 in 8/24 and the toothbrush recently stopped working despite having a full charge. After submitting my sales receipt to customer service I was told the warranty would not be honored because I did not buy the unit from one of their approved sellers.

Sad to see the poor reviews here -

My experience is, that their water jet flosser is excellent and has made a day and night improvement to my oral health, especially the gums. But also that my unit had a fault.. and I know that these type of products regardless of brand tend to die.. likely due to electricity and water - but after only a few back and forth emails on trying to fix it, Waterpik sent me a brand new unit for next day shipping. Customer service were not only very friendly and polite, but clear and reasonable - this was all months after my original purchase.. I didn’t expect a good experience with after-sales. The new unit has been going strong for months and am extremely happy. Couldn’t be happier.

After only 10 months, my Waterpik Cordless Advanced Waterflosser is already defective. (Pump no longer works) The German support is a disaster.

MATERIALE SCARSISSIMO.
DOPO ANNI DI UTILIZZO DELL'IDROPULSORE BRAUN, CON BUONI RISULTATI, MI DECIDO PER
UN PRODOTTO APPARENTEMENTE MIGLIORE.
L' idropulsore "Waterpik Dental Water" acquistato a fine giugno 2024, si è rilevato un autentico "bidone"
l'interruttore di accensione è già rotto e il serbatoio perde acqua per la mancata tenuta della guarnizione.
Inoltre, la dotazione degli spazzolini non è adeguata al lavoro che deve svolgere.
IN QUESTI GIORNI STO SCOPRENDO CHE NON ESISTE UN'ASSISTENZA IN EUROPA MA OCCOREREBBE INVIARE IL PRODOTTO NEGLI STATI UNITI!!!!
UN VERO DISASTRO. DA NON COMPRARE ASSOLUTAMENTE

Ich habe mir die Waterpik WP-100 Ultra bei einer Apotheke bestellt und heute bekommen. Bin gar nicht damit zufrieden. Selbst in der höchsten Einstellung 10 spürt man kaum den Wasserdruck. Da ist ja das hin- und herspülen im Mund stärker. Dieses Gerät kann ich nicht empfehlen.

Ich habe eine kabellose Waterpik Munddusche vor 4 Jahren gekauft. Nach 23 Monaten war sie defekt und wurde von Waterpik im Rahmen der Garantie ersetzt. Das gelieferte gleiche Ersatzmodell war nach 25 Monaten jetzt defekt. Garantie ein Monat abgelaufen. Meine Erfahrung: Die Funktion der Geräte ist gut, die Qualität das Gegenteil.

I now have 2 water flossers and each cannot charge as connection has corroded.
