Comparison B.Well WI-922 vs Waterpulse V660

No translation necessary.

The model designation helps you find the right replacement tip without the risk of incompatibility with the irrigator handle. Unlike the tip type, which describes its purpose, the model indicates the specific series or item number of the product. This parameter is especially useful when purchasing additional standard, orthodontic, or periodontal tips.

The number of intensity levels indicates how precisely the water pressure can be adjusted to match gum sensitivity and specific tasks. Low values are suitable for getting used to the irrigator and gentle treatment, while high values are for more intensive cleaning of food residues from between teeth. Intensity should not be confused with cleaning modes, which alter the nature of pulsations or the water delivery algorithm.

Additional operating modes change the way water is delivered and make it possible to adapt the water flosser to gum sensitivity or a specific care task.

— Gentle. Uses lower pressure or a softer pulsation pattern for sensitive gums and gradual acclimatization to the water flosser. It is also suitable for the first procedures after braces or orthodontic appliances have been fitted.

— Deep cleaning. Increases the intensity of the water jet or cyclically changes its intensity for more thorough cleaning of interdental spaces and the gumline. Unlike the standard mode, the program may include pauses for sequentially moving between areas.

— Gum massage. Alternates the strength or frequency of the pulses, creating a gentle pulsating effect along the gumline. The mode is intended primarily for additional gum care rather than as a replacement for basic interdental cleaning.

— Whitening. A special program for removing surface pigmented deposits, usually used together with a suitable nozzle or branded product. It may refresh the appearance of the teeth, but it does not change their natural color and does not replace professional whitening.

— Point. In Point mode, the water flosser alternates brief water delivery with pauses, making it easier to target selected a...reas. Its main difference from the standard mode is not the width of the jet but the intermittent operating cycle. During a pause, the nozzle can be moved from one interdental space to another. This format is convenient for caring for braces, crowns, implants, and hard-to-reach areas.

— Custom. A user-configurable water flosser program that is saved and accessed using a separate button. Simply select a comfortable water-jet intensity once to use it during subsequent cleanings without readjusting it. This is convenient, for example, for regular care of braces, implants, or sensitive gums. Unlike preset programs, this mode uses a individually set water-delivery intensity.

— Pulse. A selectable mode with pronounced alternation in the strength of the water pulses, designed for gum massage or more dynamic cleaning. It should not be confused with the regular pulsating water delivery that many water flossers use continuously and cannot disable.

The irrigator pressure determines the force of the water jet and directly affects cleaning intensity. Values around 20–40 PSI are suitable for getting used to the device and gentle care, while 70–100 PSI provides more powerful rinsing of hard-to-reach areas. A wide range allows you to select a comfortable flow strength for gums, implants, braces, and different nozzles.

The reservoir capacity directly affects the duration of irrigation without refilling. About 200 ml is usually sufficient for a short daily procedure, 300-400 ml for a more thorough cleaning of the entire oral cavity, and a capacity of 500 ml is convenient for braces, extended care, or use by multiple family members. The actual consumption also depends on the pressure, selected nozzle, and jet speed.

360° nozzle rotation allows you to turn it around its axis and direct the stream at the desired angle without changing the position of the irrigator handle. This makes it easier to clean the inner sides of teeth, distant molars, the gum line, and areas around braces or implants. The user needs to bend their wrist and reposition the device less, making cleaning more precise and comfortable.

Cable length affects the convenience of connecting a stationary irrigator to the power outlet and the choice of installation location. A longer cord allows the device to be placed further from the power source, while a shorter one may require the use of an extension cord.

A case or cover is designed for storing and transporting a portable irrigator together with attachments and a charging cable. It protects the device from dust, scratches, and accidental damage in luggage, and helps keep the set in one place. A hard case withstands impacts better, while a soft cover is lighter and takes up less space.
