Number of nozzles

The number of working nozzles that are standardly supplied with the device. Nowadays, options are quite common with both one and two or three nozzles in the kit; and in the most extensive sets, this number can be four or five or even more.

In many sets, several nozzles may have different purposes. For instance, an irrigator, in addition to its standard nozzle, might include orthodontic and periodontal nozzles. However, it's important to note that models with the same number of accessories in the kit can have different specific specializations. So, when making a choice, it's wise to consider not just the quantity but also the types of nozzles available. Additionally, there's an option where several identical interchangeable heads come with one handle. This configuration is particularly common in toothbrushes. It enables multiple individuals, such as family members, to use a single device, and such a set is usually more cost-effective than purchasing individual toothbrushes for each person.

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).

Full charge time

The time required to charge the battery from zero to 100% in a device with the appropriate power type (see above). This parameter can vary from 1 – 3 hours in relatively simple and low-power devices to a day in advanced models with capacious batteries. At the same time, the longer the maximum operating time on a charge (see above), the longer, usually, the time required for charging, although there is no hard dependence here.

In general, having fast charging capabilities improves the convenience of a device by reducing interruptions in its operation. However, there is a trade-off to consider: fast charging often means either a smaller battery capacity or a higher price due to the use of specialized technologies to speed up the charging process. When evaluating this parameter, it's essential to think about how you intend to use the device. For instance, if a toothbrush or irrigator is solely used at home by one person and comes with a charging stand, fast charging may not be a critical factor. The device remains consistently charged as it's constantly on the charger, and its battery doesn't deplete significantly during one use. The time between sessions, usually around 8 to 12 hours, is more than enough to maintain a charged battery, even for devices with slower charging. However, if you plan to use the device while traveling, where access to power outlets is sporadic, it's preferable to have minima...l charging time to ensure you can recharge quickly during your trips.
