Model of the replacement head
Models of replacement heads supplied with the device.
This information is valuable for assessing the capabilities of a specific model and for sourcing additional, spare, or replacement nozzles, particularly for toothbrushes and dental centers that naturally use such devices (as indicated in "Type"). Firstly, it's advisable to replace the heads in these devices every 3-6 months, similar to regular toothbrushes. Secondly, if each user purchases their own nozzle while sharing a single handle, it's a cost-effective alternative to buying a separate brush for each individual, although it may be less convenient. Regardless, knowing the model of the interchangeable nozzle will save you time and effort when searching for compatible accessories.
Power / intensity modes
The number of power modes provided in the device. For flossing systems (see "Type"), this paragraph takes into account the characteristics of the irrigator; data on the toothbrush (if they differ) are indicated in the note.
It's important to distinguish between the number of power settings and the number of operating modes, as these are distinct parameters. Refer to the "Operating modes" section for details on the various modes. In this context, we emphasize that
power adjustment, if available, may not be accessible in all modes. For example, in an irrigator offering two modes of operation—continuous jet and pulsation—power adjustment might only be available in the continuous jet mode.
Having multiple power settings enhances the versatility of the device. Even if a device technically offers only one operating mode, the ability to adjust the intensity of the treatment allows users to tailor the device for various tasks. For instance, in many toothbrushes, the traditional 2D brushing mode at its lowest power setting effectively serves as a gentle treatment option. However, it's worth noting that the capability to adjust power levels can somewhat increase the device's cost.
Max. operating time
This refers to the maximum duration a device can run continuously when powered by a fully charged battery or fresh batteries. It's worth noting that this metric may also apply to models designed for mains power, such as flossing systems that include rechargeable toothbrushes, in which case we're referring to the battery life of these toothbrushes.
It's important to note that device specifications typically indicate the maximum runtime under ideal conditions, often in the most energy-efficient mode of operation (and for models with replaceable batteries, using high-quality batteries). The actual battery life can vary depending on specific usage conditions. However, this parameter still serves as a valuable basis for comparing different models. Generally, differences in the claimed operating time correspond proportionally to the real differences in battery life. For example, if one toothbrush has a stated operating time of 20 minutes and another boasts 40 minutes, in practice, their battery life (under similar conditions) will likely differ by approximately two times.
It's important to consider that, for toothbrushes, this parameter can help estimate the number of brushing sessions you can expect on a single charge. Typically, the recommended daily brushing duration is 2 minutes. So, if a toothbrush has an operating time of 30 minutes, it's sufficient for approximately 15 cleaning sessions (or more realistically, around 14 or 13).
