Irrigator - what is it, how does it work

An irrigator is an electric device for oral hygiene, the device cleans the teeth from plaque and rinses the gaps between the teeth, gums, taking out pieces of food from there. This happens by supplying a jet of water or other liquid.

The irrigator has a special motor that pumps water / liquid and is powered by an accumulator or battery (power supply if it is a stationary device). Liquid is poured into the tank of the irrigator - filtered water, disinfectants, deodorants or therapeutic agents for the oral cavity. The motor pumps it up and feeds it into the handle hose. The handle has a working head through which the jet flies out. The fluid is supplied either continuously or at intervals. It is possible to adjust the power, speed and pressure of the jet. The tool penetrates into the gaps between the teeth, gums and washes away all the dirt from there.

User reviews about the irrigator WI-911 from B.Well

67% of users in their reviews on Yandex. Market and Rozetka positively evaluate this irrigator. The main complaints of 33% of the remaining users are related to poor build quality / materials, frequent defects, marriages and battery problems (it burns out after a month of use, and service centers refuse to accept devices under warranty, the seller also does nothing).

Consultants respond to such reviews that the battery can “burn out” if water gets on the board. This is usually due to you holding the irrigator too close to your teeth. Because of this, part of the water jet returns inside the device and hits the board, so it shorts out, and the device fails. Since such a breakdown is classified as misuse of the equipment, it is not covered by the warranty. If you replace the battery, but do not clean the board, it can turn on / off on its own.
