Choosing a budget wired vacuum cleaner often turns into finding a needle in a haystack, especially when two almost identical models from the same manufacturer are on the shelf. Xiaomi Deerma DX700 and its updated version of Xiaomi Deerma DX700S look like copies, but the devil lies in the details of the design. It is these nuances that determine how convenient it will be for you to clean the apartment after six months of active use.
Both models are classified as cyclone vacuum cleaners, meaning no dust bags and use the vortex to separate debris from the air. However, Deerma engineers have taken into account the complaints of users of the first version and made a number of design changes to the DX700S. Understanding these differences will help avoid disappointment from the purchase.
In this article, we will discuss the specifications, ergonomics and maintenance of both devices, why the new version may cost more and whether it is worth overpaying for your use case, the main difference lies in the filtration system and the mechanism for mounting the dust container.
Body design and ergonomics
Visually, the Xiaomi Deerma DX700 and Xiaomi Deerma DX700S are virtually indistinguishable from each other at arm's length. Both devices are made in their signature white with orange or gray accents typical of the Mijia ecosystem. The weight of the devices is also comparable, and is about 1.5 kg in the basic configuration, which allows you to comfortably remove curtains and ceilings.
However, on closer inspection, you can see changes in the geometry of the handle and the location of the buttons. In the DX700S, the switch is more tactile and has a slightly larger stroke, which reduces the risk of accidental pressing, and improved balancing of the center of gravity, so that the hand was less tired during prolonged cleaning.
⚠️ Note: Despite the similarity, the plastic mounting elements may differ from the models. Do not try to use accessories or adapters from the old version on the new version without checking compatibility.
The body materials in both models are made of impact-resistant plastic, but in the S version, the build quality is slightly higher, the gaps between the parts are minimized, which prevents fine dust from entering the engine compartment, which is especially important for the durability of the engine.
- 🔹 DX700: Classic handle shape, standard start button, weight 1.5 kg.
- 🔹 DX700S: Improved grip ergonomics, modified button, optimized weighting.
- 🔹 General: Compact design, wall mounting, minimalist style.
Suction power and productivity
The heart of any vacuum cleaner is its motor, and here lies one of the most important differences: the base model Xiaomi Deerma DX700 is equipped with a 15,000 Pa engine, which is enough to collect dust from hard coatings and surface cleaning of carpets with low pile.
The Xiaomi Deerma DX700S has a more efficient engine, delivering up to 17,000 Pa (in some regions specifications can range to 19,000 Pa at peak) and increased suction power allows more efficient pulling of dirt from the depths of carpeting and collecting heavier particles such as crumbs or filler from the tray.
Importantly, the power increase has not led to a critical increase in power consumption: Both models remain fuel efficient, consuming about 600 watts of electricity, but the DX700S is slightly quieter due to improved airway aerodynamics inside the enclosure.
To assess the real-world efficiency, consider not only the numbers in the passport, but also the design of the cyclone system. In the new version, Deerma optimized the angle of curling the airflow, which allows you to maintain a high suction force even when filling the container by 70-80%.
Filtration and air purification system
One of the main arguments in favor of buying a model DX700S It is an upgraded filtration system. DX700 Uses a standard set of cyclone filter and one HEPA-The filter version S has an improved multi-stage barrier.
In the updated system, a denser HEPA-filter E12, This is a very important factor for allergic people and families with young children, because the air coming out of the vacuum cleaner becomes almost sterile.
The DX700S’s filter design also provides a more convenient extraction system, so you don’t have to touch the dirty inside of the container when you change or clean the filter, which was a little more time-consuming and dirty in the old model.
💡
Wash it. HEPA-filter with cold water only without brushes and dry for at least 24 hours.
Regular maintenance of the filtration system is the key to a long life of the engine. If the filter is clogged, the load on the engine will increase, which will lead to overheating and loss of suction power. In the DX700S, the indication of filter contamination is more clearly implemented.
Dust container and ease of emptying
The volume of the dust container in both models is 0.8 liters, which is the standard for compact wired vacuum cleaners, enough to clean a two-bedroom apartment without the need for intermediate cleaning, but the mechanism of emptying has changed.
In the Xiaomi Deerma DX700, the container is removed completely, and only then the garbage release valve opens. In the DX700S model, engineers have implemented a rapid reset system that allows you to empty the container at the touch of a button without removing the container from the main unit (depending on the regional version).
Also worth noting is the transparency of plastic, which uses a material with a lower tendency to static electricity, which makes fine dust stick less to the walls, making it easier to visually control filling and reduces the frequency of washing.
| Characteristics | Xiaomi Deerma DX700 | Xiaomi Deerma DX700S |
|---|---|---|
| Suction power | 15,000 Pa | 17000-19000 Papa |
| Container volume | 0.8 l | 0.8 l |
| Type of filter | Cyclone + HEPA | Cyclone + Improved HEPA E12 |
| Discharge mechanism | Removable container | Quick reset button |
| Noise level | ~78 dB | ~75 dB |
Set and set of nozzles
Both vacuum cleaners are standard with a main engine unit, a telescopic tube, a basic floor nozzle and a slit nozzle, but the DX700S version often features an extended suite of accessories that includes a special turbobrush to collect animal hair.
The main nozzle in the new model features a softer pile and improved air intake geometry, which prevents large debris from scattering as it moves forward.The telescopic tube in the DX700S has a more robust length latch that doesn't weaken over time.
☑️ Checking the completeness when buying
The attachment is made to a standard compatible with many accessories of the Xiaomi ecosystem, which allows you to buy additional specialized tools, such as a mattress nozzle for dust mites, separately.
Maintenance and durability
The durability of Deerma's wired vacuum cleaners depends on filter cleaning in a timely manner. As with any type of technology, ignoring this rule leads to a drop in performance. The DX700S makes the filter element more convenient to access, encouraging users to monitor its condition more often.
The engine compartment in both models is protected by an additional grid, but in the new version the seals sit tighter, which reduces the risk of fine dispersed dust hitting the windings of the engine, which is the main reason for failure of such devices after 1-2 years of operation.
⚠️ Warning: Never turn on a vacuum cleaner without a filter installed.Dust entering the engine turbine will cause permanent damage and loss of warranty.
To clean the cyclone block, it is recommended to use only a dry cloth or soft brush.Using aggressive chemicals can damage the plastic and disrupt cyclone balancing.Regular prevention will extend the life of the device to 5-7 years.
Summary comparison and recommendations
To sum up, the Xiaomi Deerma DX700S is an evolutionary development of the base model. It corrects the main "childhood diseases" of its predecessor, offering higher power, better filtering and improved comfort of use. The price difference between models is often minimal, making the S version more attractive.
However, if the budget is tight and the apartment is small with mostly hard coatings, the base DX700 is still a decent option, and it will cope with daily cleanliness support, but will require a little more attention when maintaining filters.
Should I pay more for the S version?
The choice between these two models is between basic functionality and optimized comfort, both of which are great examples of what a modern, budget cleaning appliance should look like.
💡
The DX700S benefits from improved ergonomics and a more efficient filtration system, making it the best choice for most users in 2026-2026.
