Comparison Xiaomi MiJia T700 vs Xiaomi MiJia T500

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.

The number of operating 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.

The mode in this case means the general format of operation, as explained in more detail in the "Modes" section below. It's important not to confuse this parameter with the number of power settings, which are discussed separately in the "Power modes" section. These characteristics are generally distinct from each other. For instance, a toothbrush with one operating mode may have multiple power settings, and conversely, there can be just one power level with several operating formats.

Anyway, the presence of several modes significantly expands the functionality of the brush/irrigator, allowing the device to be used for different procedures (or for several users with different needs in terms of oral hygiene). The flip side of this versatility is the increased cost. In addition, note that with the same number of modes, a specific set of these modes in different models may be different; so before buying, be sure to clarify how the capabilities of the selected model meet your requirements.

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.

Modes of operation supported by the device.

Toothbrushes nowadays offer a wide range of modes beyond the traditional daily cleaning (often referred to as "2D" mode). You can find toothbrushes with options like the advanced 3D mode, as well as programs for gentle and deep cleaning, polishing, whitening, gum massage and tongue cleaning. On the other hand, irrigators typically offer different modes in addition to the standard continuous water jet. These additional modes often include pulsation and spray options.

Here is a detailed description of the most popular options found in brushes:

— Daily cleaning (2D). The "2D" mode of operation in toothbrushes closely resembles the traditional manual toothbrush experience. In this mode, the bristles of the brush move in a single plane, and the exact movement pattern may vary depending on the cleaning technology used. The intensity of brushing is typically medium to high, making it suitable for individuals with relatively healthy and not overly sensitive teeth. The recommended daily brushing time is 2 minutes, with 30 seconds allocated to each quadrant of the mouth. These corresponding settings are usually available in the timer function, if the to...othbrush is equipped with one. While "2D" brushing is somewhat less effective than "3D" (as mentioned below), it's a feature that can even be found in more affordable toothbrush models.

— Daily cleaning (3D). This feature, available in brushes with reciprocating-rotating and reciprocating-sweeping technology, involves bristle pulsation in addition to the standard cleaning motion. The pulsating movement, which goes deep into the brush head and back, enables cleaning in three dimensions simultaneously. This greatly enhances efficiency compared to the 2D cleaning mentioned earlier. These bristles not only address the outer tooth surfaces but also reach the sides and interdental spaces to some extent (though it's not a complete replacement for dental floss). However, it's worth noting that this advanced functionality typically comes at a higher cost.

— Gentle cleaning. The gentle treatment program, typically used for sensitive teeth and gums prone to bleeding, is common in brushes with reciprocating-rotating and reciprocating-brushing technologies. In these brushes, the gentle mode often involves reducing the nozzle's rotation or vibration speed. In sonic and ultrasonic models, gentler treatment is achieved by reducing vibration intensity. Regardless of the technology, this mode aims to minimize discomfort during brushing and the risk of gum damage, even when using standard nozzles. For the gentlest effect, it's advisable to use this function with a nozzle designed for sensitive teeth.

— Deep cleaning. Most often, this name means cleaning with a standard intensity, but an increased duration — for example, 3 minutes instead of the usual 2 minutes (45 seconds for each quadrant of the mouth instead of the traditional 30 seconds). This mode allows you to effectively clean your teeth and remove dirt, for which normal daily brushing is not enough.

— Polishing. A mode for treating relatively clean teeth that do not require a full-length cleaning. Usually, polishing is carried out at a reduced frequency of vibrations (rotations) and takes noticeably less time than conventional processing (for example, 1 minute instead of the traditional 2 minutes).

— Whitening. A special mode for whitening tooth enamel and removing stains, especially from the front teeth, is often an extended version of the regular brushing mode. For example, in a whitening mode, the brush might operate normally for 2 minutes and then switch to increased intensity for 30 seconds. Specific details about this mode, including any contraindications (especially for individuals with sensitive teeth or gum issues), should be checked separately.

— Massage gums. Gum treatment can be offered either as a separate program or as an add-on to the regular brushing routine. In the latter case, it typically involves a standard 2-minute toothbrushing program followed by activating an additional mode. This function not only ensures effective cleaning but also contributes to gum strengthening. It can be beneficial for addressing issues like inflammation and bleeding gums, although consulting a dentist is advisable in such cases.

— Cleaning the tongue. A separate mode for tongue cleaning is available in many electric toothbrushes. Brushing the tongue with an electric toothbrush can often cause discomfort due to tickling, so this mode typically offers a brief cleaning session lasting about 20 seconds. If needed, you can perform multiple sessions. It's important to note that the presence of a tongue cleaning mode doesn't necessarily mean that a specialized nozzle for tongue cleaning is included in the kit (as discussed in the "Nozzles" section), although it's commonly included.

It should be noted that in some toothbrushes, the mode change is carried out due to “smart” nozzles: when such a nozzle is installed, the device recognizes it by the built-in chip and automatically switches to the appropriate programme.

In turn, in irrigators, the features of the main modes are as follows:

— Jet (monoflow). The classic, most popular working format: a constant jet with a constant pressure. Provides sufficient efficiency for most tasks for which irrigators are used, while being extremely simple to implement and can be provided even in the most inexpensive models.

— Pulsating. Water supply with variable pressure. This mode is especially effective for removing dirt from the interdental space, under braces and in other hard-to-reach places.

— Spray. In this mode, a mixture of water and air is fed through the nozzle, due to which, instead of the usual jet, a cloud of small droplets flying at high speed is obtained at the exit. This mode is great for massaging the gums and general cleaning of the mouth.

The frequency of sound vibrations provided by a brush with a sonic or ultrasonic principle of operation (see "Cleaning technology").

A high oscillation frequency (from 40 000/min and above), ositively impacts the efficiency and quality of oral processing. In fact, brushes that generate more than 40,000 oscillations per minute are often referred to as ultrasonic brushes, although true ultrasound starts at much higher frequencies. However, it's important to note that these high-speed brushes tend to come with a higher price tag. It's also worth mentioning that for specific tasks, such as delicate treatment of sensitive teeth, relatively lower frequencies may be more suitable. Therefore, when choosing an oral care device, it's essential not to prioritize the maximum oscillation frequency but rather consider the individual needs of the user(s). Consulting a dentist for personalized recommendations is a prudent approach.

It's important to clarify that in this context, a full cycle of bristle movement is defined as one complete oscillation, which includes both the forward and backward motion. Some manufacturers employ a marketing tactic where they list their brush's operating frequency not in terms of complete oscillations but as the number of movements per minute, counting only half of the cycle — either the forward or backward motion. This can lead to impressive-sounding numbers in product specifications since the count...of movements is double the count of oscillations. However, the primary performance metric remains the number of complete cycles or oscillations, and that's the value provided in this section of our catalog.

The presence of a timer in the design of the device. All types of dental hygiene appliances can be equipped with this function (see "Type").

The timer function counts down and provides alerts, often at specific intervals, to help users monitor the time spent on brushing their teeth and mouth. This ensures that the oral care routine is effective without unnecessary prolongation. The timer settings can vary depending on the selected brushing program (as discussed in the "Modes" section). Following the standard recommendations of dentists, a typical daily brushing session should last at least 2 minutes, with 30 seconds allocated for each quadrant of the teeth. Consequently, when using this mode, the timer typically counts down from 2 minutes and signals every 30 seconds to prompt the user to move the brush to another section of the mouth.

The timer function can vary in its operation, depending on the specific model of the toothbrush or irrigator. The simplest approach involves fixed time settings for each mode, accompanied by audible and/or visual signals. Models equipped with smartphone synchronization (as discussed in the "Synchronization with a smartphone" section) often display timer data on the smartphone screen and allow users to customize the countdown duration to their preferences. In some children's brushes (as mentioned earlier), a musical timer is used, where the countdown continues until a melody finishes pla...ying. There are also other unique features related to this function. Regardless of the specific implementation, the timer simplifies the use of the toothbrush or irrigator, eliminating the need for users to manually track the time themselves.

The presence of its own display in the design of the device.

These displays are typically small due to the compact size of the toothbrush or irrigator body. They usually offer basic functionality, capable of displaying one color and a limited set of characters. However, even with such constraints, they can convey various operational information, such as the selected mode, timer countdown, battery status, error messages, and more. As a result, these displays enhance overall convenience and visibility when using the device.

On the other hand, it's important to acknowledge that there's a growing number of models without displays, especially in the mid to high-end range. This shift is primarily driven by the widespread adoption of smartphone synchronization (as mentioned earlier), which offers several advantages over built-in screens. Firstly, the Bluetooth module required for synchronization is smaller and more cost-effective than a dedicated display. Secondly, smartphone screens and other control gadgets tend to be larger, more versatile, and easier to read compared to the small screens on toothbrush or irrigator handles. Additionally, the display on the device's handle is not visible during use, whereas a smartphone can be positioned in front of your eyes. As a result, it's worthwhile to seek out a model with this function if the ability to access data from a display is a crucial factor for you, regardless of whether...you have a smartphone or another additional device at hand.

Additional items supplied with the device (in addition to the base and attachment set).

The most popular types of such items nowadays are charging stand, accessory stand, UV sanitizer and case ; Here is a more detailed description of each option:

— Charging stand. A battery charging device designed as a stand serves the dual purpose of recharging the battery and offering added convenience for storing the device. It's worth noting that this function can apply to dental centers, even if they primarily operate on mains power (as indicated in the "Type of power" section). In such cases, the toothbrush included with the dental center typically runs on batteries, and the charging stand is typically integrated directly into the main unit of the dental center for ease of use.

— Stand for accessories. A device designed to hold various accessories, primarily interchangeable nozzles, can come in different designs. For example, in toothbrushes and portable irrigators, this device is often integrated into a charging stand, which includes both a charging socket and open compartments for accessories. In irrigators and fixed-layout dental centers, these compartments are usually built into the main unit or the lid of the water tank. In this case, the compartments are typically covered with lids for hygiene reason...s, making it a more hygienic option. Regardless of the design, having a dedicated stand for accessories enhances the convenience of storing them.

— UV sanitizer. A device that uses ultraviolet (UV) radiation for disinfecting the device, particularly replaceable nozzles, is typically designed as a distinctive container. In some models, this container also serves as a cover or case. The disinfection process effectively eliminates the majority of pathogenic bacteria and viruses, all without the need for additional chemicals and ensuring safety as the radiation remains confined within the container. However, it's important to note that UV disinfection is not effective against regular dirt and debris, so having this function doesn't eliminate the need to clean the nozzle through washing.

— Case / cover. The device comes with a storage and carrying container, which can be either a hard case or a soft cover. Hard cases offer better protection, while soft covers are more compact and can be rolled up when not in use. Regardless, both of these accessories are highly convenient for storage and transportation. They safeguard the contents from dirt and damage, and in many cases, provide space to store additional accessories, reducing the risk of losing them. While you could use makeshift packaging for the same purpose, the provided container is typically more practical.

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).
