When choosing a wireless vacuum cleaner for the budget segment, many users face a dilemma: take a time-tested model or overpay for a new product with improved performance. The Deerma line, which is a sub-brand of the Xiaomi ecosystem, offers two flagship solutions that are often confused due to the external similarity. The DX700 and DX700S models do have a lot in common in design, but their internal content and functionality differ significantly.
In this article, we will take a closer look at the technical details so you can make a smart decision. Understanding the difference between these devices will save you money or avoid the frustration of not having enough cleaning power. It is worth noting that the letter "S" in the title often indicates an improved version (Super or Special), but this does not always mean a radical change in design.
Both are vertical wireless vacuum cleaners, making them ideal for quick daily cleaning in apartments and homes. But it's the details of engineering that determine how comfortable you'll be using the device every day. Let's dive into a comparative analysis to determine the winner in this technological duel.
Body design and ergonomics
Visually, the Xiaomi Deerma DX700 and its updated version of the DX700S are almost identical, which often confuses buyers. Engineers have retained a recognizable minimalist matte-coated silhouette that fits perfectly into modern interiors. The weight of the devices is also comparable, at about 1.5 kg in the basic configuration, allowing you to comfortably clean even with one hand without experiencing fatigue in the wrist.
But if you look closely, you can see differences in the position of the buttons and the texture of the plastic. The DX700S uses a higher-quality polymer that is less prone to scratching and better able to resist scuffling over time. The handle is ergonomically placed in the palm of your hand, and the center of gravity is balanced closer to the operator's hand, making it easier to control weight.
The main mounting is a click-through mechanism that allows quick assembly and disassembly without the use of tools, especially when it comes to emptying the container or cleaning the filter. Despite the similarity, the internal layout of the engine compartment in the S version has undergone changes to improve heat sink.
⚠️ Note: Despite the appearance of similarities, accessories from DX700 may not come close DX700S Always check the compatibility of the attachments before buying additional sets.
The build quality of both devices is high for its price segment: plastic does not creak, the gaps between the parts are minimal and uniform. For storage, there is a wall stand that comes with a kit that allows you to compactly place the vacuum cleaner and all the nozzles in one place.
Suction power and operating modes
The main technical difference, which many are willing to pay for, is the suction power. The DX700S is equipped with a more advanced engine that generates pressures of up to 23,000 Pascals. For comparison, the basic version of the DX700 offers 19,000 Pa. At first glance, the difference seems small, but in practice it affects the quality of carpet cleaning and collection of large debris.
Both vacuum cleaners support two main operating modes, switching between them with a button on the handle: in standard mode, the devices work quieter and consume more battery power, which is suitable for daily maintenance cleaning. Turbo mode is turned on to combat severe pollution, but significantly reduces battery life.
The cyclone filtration system is both effective, but the DX700S has improved air channel aerodynamics, allowing for high suction strength even when the container is filled, while the older model may experience a performance decline.
It is important to remember that the actual power depends not only on the engine, but also on the condition of the filters, and regular cleaning of the cyclone system is the key to stable operation.
- 🌪️ DX700S: Up to 23,000 Pa, ideal for carpets with pile and animal hair.
- 💨 DX700: Up to 19,000 Pa, it copes well with hard floors and light dust.
- 🔋 Autonomy: In Turbo mode, both vacuum cleaners operate near the 15-20 minutes, in economy, until 45-50 minute.
Filtration and hygiene system
One of the key aspects of choosing a modern vacuum cleaner is the quality of the outlet air. Both Xiaomi devices in question use a multi-stage filtration system, but with important nuances.
Model DX700S received an update HEPA-This allows the smallest particles of dust, pollen and allergens up to 0.3 microns to be trapped with an efficiency of 99.97%. DX700 also established HEPA-filter, but its life and efficiency at high loads is slightly lower.
The dust collector design is designed to be cleaned, which is a big plus for hygiene, but the filters themselves require careful handling, cannot be twisted or rubbed heavily, rinsed with enough water and thoroughly dried for 24 hours before re-installing.
How often do you change filters?
Using a vacuum cleaner without a filter is strictly prohibited, as it can cause dust to enter the engine and break it. The engine protection system in the DX700S is more advanced and better sealed against fine fractional dust.
| Characteristics | Xiaomi Deerma DX700 | Xiaomi Deerma DX700S |
|---|---|---|
| Suction power | 19,000 Pa | 23 Pa. |
| Type of filter | HEPA (standard) | HEPA (enhanced) |
| Container volume | 0.8 l | 0.8 l |
| Noise level | 75 dB | 72 dB |
Complementation and nozzles
The packages can vary depending on the delivery region and the particular store, but the basic set is usually standard.Both vacuum cleaners come with a basic motorized brush that effectively knocks dust out of carpets thanks to a rotating roller with bristles.
The kit also includes a narrow slotted nozzle for hard-to-reach areas, a brush for furniture and textiles with soft bristles, and an extension tube. In the DX700S version, you can sometimes find additional accessories, such as a special nozzle for collecting wool or an improved holder for wall mounting.
The main brush of both models is equipped with LED lighting, which allows you to see dust under the bed or sofa. The 180-degree rotation mechanism of the head provides excellent maneuverability around the legs of the furniture.
☑️ Checking the completeness when buying
The newer DX700S often uses an antistatic pile that is less electrified and does not scatter fine dust back into the air.
Autonomy and charging process
Battery life is a critical parameter for wireless devices, both of which are equipped with lithium-ion batteries with a capacity of about 2200-2500 mAh. In economical mode, they can work up to 45-50 minutes, which is enough to clean an apartment of 60-80 square meters.
At maximum power, the operating time is reduced to 15-20 minutes, which is usually enough for express cleaning or cleaning of carpets in individual rooms, and it is important to note that the actual operating time depends on the type of coating and the degree of contamination.
The charging process takes about 3.5-4 hours. The indicator on the body signals status: flashing red means low charge or charging process, constant green is full charge. The power supply is compact and does not take up much space at the outlet.
⚠️ Warning: Do not leave the vacuum cleaner on charge for longer than 24 hours after full charge, although the system BMS (Battery Management System) and protects against overcharging, it can reduce the total battery life in the long run.
To extend the battery life, it is recommended not to discharge the device "to zero" regularly, but it is optimal to put it on charge when the indicator shows about 20% of the residual charge.
Maintenance and durability
The durability of a vacuum cleaner depends on proper care, and the focus should be on cleaning the container and washing the filters in a timely manner, and if you ignore these procedures, the suction power will begin to fall and the engine will work with increased load.
The DX700S simplifies access to the pre-cleaning filter, which encourages users to do more often.The cyclone design makes it easy to extract compressed dust in one motion, minimizing hand-to-hand contact with dirt.
Regularly check the rotating brush of the main nozzle for wound hair and threads, removing them will prevent jamming of the brush motor and break of the drive belt. The kit often comes with a special device or knife for easy cleaning of the roller.
💡
Regular cleaning of the cyclone filter and the lack of contact with water in the engine compartment are the main conditions for the long service of your Deerma vacuum cleaner.
If there is extraneous noise or vibration, you should immediately stop using and check the integrity of the fan blades and engine bearings. Self-repair of complex components is not recommended, it is better to contact an authorized service.
Summary comparison and recommendations
To sum up, the Xiaomi Deerma DX700S is an evolutionary development of the base model, offering better power, quieter performance and improved filtering. If budget allows, opting for the DX700S version looks more rational in the long run.
But the DX700 is not worth writing off either: For small flats with predominantly hard coatings (laminate flooring, tiles), its 19,000 Pa capacity is more than enough. The price difference between the models is often small, but on stocks, the basic version can be bought very profitably.
Both devices represent a great entry-level option to the world of wireless cleaning from the Xiaomi ecosystem.They are lightweight, maneuverable and easy to maintain, making them popular with users around the world.
