#2
Ultra Professional
by Waterpik
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.

Overall Rating: 4.0/10
Price: £108.99
Pros
Solid cleaning power with effective water pressure
Large water tank capacity for longer use without frequent refills
Adjustable pressure settings for a customizable cleaning experience
Cons
Bulky design, takes up space in the bathroom
Outdated look and operation, feels less modern
Not portable – stationary device requiring a power socket
High price for mediocre performance compared to more compact options
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 The build quality feels outdated, and despite the high price, it lacks features such as a display or smart settings.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.
#3
Philips Sonicare 3000
by Philips
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.

#4
Panasonic Series 800
by Panasonic
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.

#5
Vimmk Cordless Water Flosser
by Vimmk Cordless
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.
