Model of replaceable nozzle
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.
Additional modes
Additional operating modes change the water flow pattern and allow the irrigator to be adapted to gum sensitivity or a specific care task.
— Delicate. Uses lower pressure or a gentler pulse pattern for sensitive gums and gradual adaptation to the irrigator. Also suitable for the first procedures after fitting braces or orthodontic appliances.
— Deep cleaning. Enhances the jet effect or cyclically changes its intensity for more thorough treatment of interdental spaces and the gumline. Unlike the standard mode, the program may include pauses for sequential movement between areas.
— Gum massage. Alternates the strength or frequency of pulses, creating a gentle pulsating effect along the gumline. The mode is mainly intended for additional gum care rather than replacing the main cleaning of interdental spaces.
— Whitening. A special program for removing surface pigmented stains, usually used together with a suitable nozzle or branded product. It can refresh the appearance of teeth but does not change their natural color and does not replace professional whitening.
— Pulse. A switchable mode with pronounced alternation in water pulse strength, designed for gum massage or more dynamic cleaning. It should not be confused with the regular pulsating water flow..., which is used continuously in many irrigators and cannot be switched off.

Irrigator pressure
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.
Wall mount
The ability to fix the body, base, or holder of the irrigator on a vertical surface frees up space near the sink. Wall mounting is particularly convenient for stationary models, as the handle and hose remain within reach and the device is less obstructive on the countertop.
