Consider these other flossers
If you are looking for a countertop water flosser, then truthfully I think there is little reason to really consider any others, because the Ultra Professional is so good.
In fact, this water flosser is the one we recommend as the best overall water flosser.
Unless you have a specific need for a cordless flosser, or want a feature not available on the Ultra Professional should you consider something else.
Design, usability, clean & general use
This is not the most exciting product you will ever unbox, the packaging is fairly standard for this type of product.
The outer box has lots of strong marketing messages and product features highlighted. While this can be overbearing at times, at least it is well laid out and easy to distinguish.
Some packaging is so basic you really can’t get much info about a product before you buy it.
There are 4 versions of this flosser. The difference is the colour of the units. Technically they are all the same.
The colours and their model numbers are:
- White – WP-660
- Black – WP-662
- Blue – WP-663
- Grey – WP-667
I’m testing out the WP-662UK here for this review, the box was colour matched which is nice to see.
Once unboxed you will notice the unit is not small but actually nicely sized and well designed given that there is a 600ml tank built into it.
On the top is a lid which lifts up and locks into place to allow the clear water tank (complete with ml and Oz markings) be lifted out and filled.
The tank has a valve which seals closed until it is firmly pressed back into the unit at which point the seal opens to allows water to flow into the pipework ready for pumping out of the nozzle.
7 different tips come supplied with the Ultra Professional as you will see in the box contents listing.
The nozzles that are provided are:
- 3 x JT-100E – Waterpik Classic Water Flosser Tips (view on Amazon)
- 1 x OD-100E – Waterpik Orthodontic Tips (view on Amazon)
- 1 x PS-100E – Waterpik Plaque Seeker Tips (view on Amazon)
- 1 x PP-100E – Waterpik Pik Pocket Tips (view on Amazon)
- 1 x TB-100E – Waterpik Water Flosser Toothbrush Tips (view on Amazon)
There only other nozzle that is not supplied is the:
- TC-100E – Waterpik Water Flosser Tongue Cleaner (view on Amazon)
It is worth noting that the likes of the toothbrush tip actually came in black colour to match the unit I am using. Other variants come with white coloured tips. Sourcing a black coloured toothbrush tip as a separate accessory is very difficult.
Each tip works best in different scenarios.
The classic tip and toothbrush is best for most everyday use.
If you have braces, the orthodontic tip is ideal.
Pik pocket tip is suited to those with periodontal pockets and furcations.
Those with implants, crowns, retainers and bridges will likely see best results from the plaque seeker tip.
The left hand side of the unit has a plastic panel that leads up to the hinging for the lid. When opened and the tank removed, just inside are 2 holes into which your most used tips can be stored.
This is a neat solution, but does not give a home to all 7 tips. A 3rd could remain fitted to the handle.
Waterpiks other model, the Ultra, is better equipped to store multiple heads.
For most, users there will be favoured heads and not all will need and want all so you will have to make your decision as to what is most suitable for you.
Under the water tank is the main body of the unit that houses the pump and electrics. This is encased in the smooth to touch plastic.
There are 5 rubber feet on the flosser slightly raised off the worktop.
Sitting at the front of the unit (slightly off centre to the right) is the main nozzle/handle.
Docked into a little holder the length of hose coils into a recess within the body of the flosser. You have about 100cm of length from the tip of the nozzle to the hose running into the flosser. That is enough length for most.
The hose is colour matched too and the handle is accented with nice silver/grey switches. The blue and grey variants have white hoses, so these are not colour matched to the unit.
On the side is a sliding switch to release the nozzle which on the front is a much larger and clearly market On/Off slider. This controls the water flow.
The handle is rounded and tapered and fits nicely in the hand. Although smooth there is a contour to the plastic that helps with grip and there are 3 ridges on the water control slider switch.
At the top of the handle is where the detachable nozzle fits and the upper section of the handle can be rotated a full 360 degrees to position the nozzle tip precisely.
The ridged texture to this rotating dial is very useful to help the fingertip grip onto and control the tip rotation whilst in use.
To the left are more controls. A raised power button actually turns the unit on and off.
A concave button below switches between ‘Floss’ and ‘Massage’ mode.
Below this is a largish knob that can be rotated to match up with the 10 pressure settings available.
The rear of the unit has the power outlet cable that stretches to about 140cm.
A 2 pin connector is found on the end to connect to the sockets found in most UK bathrooms.
If you do not have a socket in the bathroom (like me) you can buy adapters to connect it to a 3 pin UK mains supply but be aware of the complications with trailing cables and positioning and using a unit safely.
When it comes to actually using the steps you need to take are outlined earlier in this review.
However, there are some things to note and be aware of that help you and improve your use.
It is not essential, but recommended to use lukewarm water. This is because it is more pleasant on your gums when flossing.
You can use mouthwash but it would be expensive and wasteful and if you want an extra shot of freshness or flavour to the flossing add a capful or two to the water tank.
The tank has measurements for 600ml/21 ounces, but filled to the brim can hold 22 ounces/651ml.
Set to the highest pressure setting of 10, the tank will drain in about 90 seconds (1 minute and 30 seconds).
Set to the lowest setting, it lasted for around 4 minutes and 45 seconds.
Subject to how you use it you will likely get 2 flossing sessions out of it.
And when in use, it is quite quiet, producing a noise in the region of 72 decibels.
For the best results, you should start with the back teeth and work forward. Direct the jet at a 90 degree angle, working along the gumline with a brief pause between teeth. The rotatable tip will aid with this. As you get more proficient you will be able to twist the nozzle without having to stop the water flow.
When in use the unit will pause very briefly at 30 seconds to remind you to move onto the other arch of your mouth. If you have an electric toothbrush with a built–in timer it is a similar principle.
At 60 seconds it will pause again to let you know you have reached the recommended usage time.
It need take no longer than a minute to floss your mouth. You do not need to spend 2 minutes like you do with a toothbrush.
You should not use the flosser for more than 5 minutes in any 2 hour period and it will automatically shut off if used for 5 continuous minutes as a safety precaution.
Selecting the ‘Floss’ mode and changing the pressure setting is most common, but this model does too have a Hydro-Pulse Massage.
Essentially a unique pattern of water exits from the nozzle and can be used on the gums to stimulate them. This is ideal for those with sensitive gums and suffering from periodontal disease.
Now make no mistakes if you are new to this, it is more messy than regular flossing and it will take some getting used to. Don’t be surprised by a lot of dribbling and maybe a big of spray (it’s only water). But soon it will be easier and more enjoyable.
You can’t pop this in your bag or pocket for a quick freshen up on the go, but the water reaches deep into the mouth and really does remove bacteria and food stuffs you didn’t even realise were there.
You won’t be struggling to get to your back teeth like you do with regular floss due to the long nozzle and easy reach.
The power/pressure setting choice will be personal, most I believe will hover from about 5-7, that feels like a nice comfortable mid ground. There are 10 settings to choose from ranging from 10 to 100 PSI. 10 is very powerful.
With any pressure setting, you can feel the water flosser working. The cleaning results are impressive. You can certainly feel and in some cases see the debris being cleaned from between the teeth.
How often you use this is up to use. Once a day is the minimum you should use it really.
It can be used perhaps after a meal to quickly freshen up as an alternative to brushing the teeth.
Many of us suffer with red, swollen or bleeding gums and that is believe it or not as a result of not flossing or brushing correctly. It is the bacteria buildup that causes the gums to react.
Regular use will lead to healthier gums as the bacteria is removed and the gums begin to recover. So confident are Waterpik that they offer a 14 day money back guarantee as well as a 2 year warranty.
If you purchase a Waterpik Water Flosser and don’t feel it’s improved your gum health, they will refund your money – no questions asked. What have you got to lose?
I think this is as close to perfect as you can get for a water flosser…unless there is one that can help master the technique better.

Price & where to buy
I have included links to buying options here at the start of the review.
In the section below, I discuss the price more generally and in relation to similar products.
There is a physical cost to this flosser and that recommended retail price is £79.99.
The good news is that without much shopping around you can save about £10-15, with the average selling price being around the £65.
Shop smart and you may save another £5, but often the sale price is not too far from the retail price, because the RRP is not over inflated like it is with some other dental products.
Assuming one user, using this over a 3 year period, the cost of ownership would work out at approximately £77 which is 7p per day.
This does include the cost of replacement nozzles.
Classic jet tips come in a pack of 2 and retail at £8.99. That makes each jet tip £4.50.
Prices of course do vary, but without much shopping around you can pick up a pack for £8, making each nozzle £4.
It is fair to say these are not ‘cheap’. The recommendation is to replace them every 6 months. They don’t need replacing all that regularly.
Other nozzle styles require replacement every 3 months.
No denying that good old string floss is as much as 7 times cheaper, but what price do you pay for convenience.
I reckon each flossing session you save yourself about a minute (not a scientific study).
Not only is there the time saved, there is the ease with which water flossing is completed in comparison.
What price can you put on the convenience that comes as a result?
Yes cheaper options exist, but they do not have all the same features, you are getting a very good option for less than 10p per day and the benefit will be your oral health.
Get more members of your family using it and there are only further savings to be made by sharing the cost between more users.
Please note that all prices quoted are approximates and will vary based on location, supplier and time of purchase. These figures were correct at the time of writing and should not be relied upon as hard fact, but used as a guide during your decision process.
Summary of price & where to buy
- Recommended retail price of £79.99
- Average selling price £65, can be under £60
- Replacement nozzles retail for £4 each
- Daily cost around £0.07 over 3 years
- Expensive but arguable benefits
Reliability & long term use
To suggest that this would never go wrong I cannot.
However, there are few complaints of Waterpik products being inherently faulty.
Compared to the Freedom Cordless flosser I have used from Waterpik this looks and feels more premium.
In the few weeks I have tested all has worked fine and I see little in the way of obvious weaknesses. Buttons are fairly resistive, the pressure control knob is not loose and other fitments solid.
There are not lots of parts to go wrong, but electrical products can fail, particularly when near water like this is. However, it is backed by 2 year warranty.
I suspect you will get good value from this unit.
It is arguably a slightly expensive luxury, when flossing the old fashioned way is cheaper.
However, there is a lot to be said for the convenience and the way in which you will be more encouraged to use this and I believe floss more regularly than you would otherwise.
It is not small, it does require mains power but it has been well designed and comes with a good selection of tips that makes this work particularly well in a family environment.
The adjustable pressure caters to different users needs and timers help prevent over flossing but also encourage better routines.
Convenience and the comfort in flossing with the Waterpik are the biggest draws.
The 2 year warranty is a bonus and offers a nice extra peace of mind to this investment.
This is the best corded water flosser available today in my opinion.
- Height – 29cm
- Width – 15cm
- Thickness – 13cm
- Weight (without water) – 813g
All are approximates

I’ve had this model for just over a couple of years now. I find it great. But…
It has now started to “let go” of the tips mid floss. Is there an adjustment I can do, or is it a case of biting the bullet and forking out for a replacement handle (Which have been out of stock for some time at waterpik UK )
Sorry to read about this issue Dominic. Have you spoken to Waterpij directly about this issue? It may well be covered under warranty and as such no charge to yourself.
In UK warranty is only 2 years and not 3 years
Thank you for bringing this error to our attention Brian. The review has been updated.
Can the flosser be used on the inside of the teeth, in particular on the lower jaw?
Yes it can be.
Does the toothbrush have automatic brushing motion like regular electric toothbrushes, or is it a manual brush that issues a simultaneous water jet?
This water flosser does come with a toothbrush tip, however this has no brushing motion, it is up to you as the user to move the tip to perform the brushing action, like you might a regular manual brush.
Whilst the toothbrush tip is included, we would always advise using a regular manual or electric toothbrush after using the water flosser.
Using the toothbrush tip from Waterpik in our opinion is not really a replacement to regular toothvbrushing.
