Comparison B.Well PRO-911 vs B.Well WI-911

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 alter the water delivery and allow the irrigator to adapt to gum sensitivity or specific care tasks.

— Gentle. Utilizes reduced pressure or a softer pulse pattern for sensitive gums and gradual adjustment to the irrigator. Also suitable for initial procedures after the installation of braces or orthopedic structures.

— Deep Cleaning. Enhances jet impact or cyclically varies its intensity for more thorough processing of interdental spaces and the gum line. Unlike the regular mode, the program may include pauses for sequential transition between areas.

— Gum Massage. Alternates pulse strength or frequency, creating a gentle pulsating effect along the gum line. This mode is mainly intended for additional gum care rather than replacing the primary interdental cleaning.

— Whitening. A special program for removing surface pigmented stains, usually used in conjunction with an appropriate nozzle or proprietary product. It can refresh the appearance of teeth but does not change their natural color and does not replace professional whitening.

— Pulse Mode. A switchable mode with pronounced alternation of water pulse strength, designed for gum massage or more dynamic cleaning. It should not be confused with the regular pulsating water delivery,...which is used continuously by many irrigators and cannot be turned off.

The number of pulsations per minute indicates the rhythm of the water jet's impact on teeth and gums. Frequent impulses sequentially loosen and wash away impurities, and the flow feels more continuous and gentle. However, for example, 1800 pulsations per minute are not necessarily more effective than 1200, as the result also depends on the water jet's strength, the nozzle, and the irrigator's design.

The pressure of an irrigator characterizes the force of the water jet and directly affects the intensity of cleaning. Values around 20 – 40 PSI are suitable for acclimation and gentle care, whereas 70 – 100 PSI provides more thorough rinsing of hard-to-reach areas. The wide range allows you to select a comfortable flow strength for gums, implants, braces, and various attachments.

Removable water tank makes servicing the irrigator more convenient and hygienic. The reservoir can be filled separately under the tap, thoroughly rinsed, and left to dry without having to turn the entire device over. This design is especially useful when frequently using rinses or solutions, after which the tank should ideally be cleaned immediately.

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.

The timer helps maintain the recommended duration of the irrigator's operation and systematically treat all areas of the oral cavity. The timer can emit short signals at equal intervals or stop the water flow after the program ends. It is especially useful for beginners and children who find it difficult to independently control the procedure's duration.

The full charge time indicates how long it takes to recharge the irrigator's battery from the minimum level to 100%. This parameter is especially important for models with limited battery life that need to be charged more frequently.

USB connectivity makes charging the irrigator more versatile and frees the user from being tied to a specific power adapter. The device can be charged from an outlet using a USB adapter, from a computer, or an external battery, which is especially convenient during travel.
