Best Water Flosser: No.1 Choice
Looking for a cleaner, healthier mouth? Modern water flossers remove up to 50% more plaque than traditional string floss – and they do it gently and effectively. With high-pressure pulsations that reach deep between teeth and below the gumline, these devices don’t just freshen up – they elevate your oral care routine.
But not all models are created equal. Which water flosser delivers the best cleaning performance, ease of use and value for money? Our expert team tested the UK’s leading models – and one brand clearly came out on top. Below, you’ll find the top 5 water flossers in the UK for 2025 – including our number one pick.

To determine the best water flossers for everyday use, we conducted an in-depth hands-on test.

Battery Life
How long the toothbrush lasts on a full charge under regular use
Build & Design
Quality of materials, durability, and how modern the brush feels
Noise Level
How quietly the toothbrush operates during use
Included Accessories
What’s in the box – from travel cases to replacement heads and charging stations

Ultra Professional
by Waterpik
Overall Rating: Excellent (1+)
The Waterpik Ultra Professional is often regarded as a classic among stationary water flossers. However, in direct comparison, the model reveals some significant weaknesses. It does provide solid cleaning performance and easy operation, but its bulky design is neither modern nor particularly practical for daily use.
In terms of sound level and mobility, it clearly falls behind more compact models. The build quality feels outdated, and despite the high price, it lacks features such as a display or smart settings. In our tests, it failed to impress in handling and the overall package.
Overall Rating: Satisfactory (4/10)
Price: £95.00
Pros
Cons
Solid cleaning power with effective water pressure
Bulky design, takes up space in the bathroom
Large water tank capacity for longer use without frequent refills
Not portable-stationary device requiring a power socket
Adjustable pressure settings for a customizable cleaning experience
Outdated look and operation, feels less modern
High price for a mediocre performance compared to more compact options
#3
Philips Sonicare 3000
by Philips
Overall Rating: Excellent (1+)
The Philips Sonicare 3000 looks modern but fails in key areas. The cleaning performance is underwhelming, leaving areas between teeth less clean than other models. The design is awkward, with a non-adjustable nozzle and poor ergonomics. Its battery life and noise level are also drawbacks, making it less practical for everyday use. For the high price, it doesn’t deliver the value expected compared to more effective alternatives.
Overall Rating: Limited (4/10)
Price: £62.44
Pros
Cons
Cordless design for better convenience and portability
Nozzle difficult to rotate, making it awkward for precise cleaning
Four cleaning modes for tailored dental care
Slippery casing, not ideal for long usage sessions
OLED display showing modes and battery status for better control
Very loud during operation, which can be uncomfortable
Limited features for the price, especially compared to more advanced models
#4
Panasonic Series 800
by Panasonic
Overall Rating: Excellent (1+)
The Panasonic Series 800 offers modern ultrasonic technology with five adjustable water pressure levels. However, its 200ml water tank is relatively small, requiring frequent refills, which can be inconvenient. Additionally, the non-removable tank makes cleaning more difficult. Despite featuring a quick charge function, its battery life lasts only about 10 minutes, which can feel insufficient for regular use. Considering its higher price, the value for money is rather average compared to other models.
Overall Rating: Limited (5.5/10)
Price: £160.00
Pros
Cons
Compact, modern design for easy storage and use
Small water tank, requiring frequent refills
Five pressure settings for customizable cleaning

#5
Vimmk Cordless Water Flosser
by Vimmk Cordless
Overall Rating: Excellent (1+)
The Vimmk Cordless Water Flosser offers a low price with good accessories, but it falls short in key areas. The cleaning performance is underwhelming, and the water pressure doesn’t provide an effective clean. Despite having five modes, the device lacks the ergonomic design and build quality found in more premium models, making it uncomfortable to handle. The battery life is short, and it requires frequent recharges. Overall, it offers a mediocre user experience, especially considering its competitors in the same price range.
Overall Rating: Insufficient (4.5/10)
