Comparison of vacuum cleaners Deerma DX700 and DX700S: key differences

The modern cleaning market is full of models that seem to be identical at first glance. The Deerma brand, part of the Xiaomi ecosystem, produces many devices whose names differ only by one letter or number. This is the situation with the popular vertical models DX700 and DX700S. It can be extremely difficult for a consumer who is not immersed in technical details to understand whether it makes sense to overpay for a more expensive version or just a marketing ploy.

Both are wired vertical vacuum cleaners, which already implies certain limitations and advantages over battery-powered ones. The main advantage here is a stable suction power that does not fall over time, as happens with battery discharge. However, it is the design features and filtration systems that become the watershed that separates these two modifications. In this article, we will examine in detail what lies behind the prefix "S".

Choosing between these models is often a dilemma for buyers looking for a balance between price and functionality. DX700S Uses a cyclone filter with HEPA-protection, while the basic model DX700 It relies on a simple foam sponge, and it's not just a formality, it's a factor that directly affects the quality of cleaning and, more importantly, the health of allergy users.

Design features and ergonomics

The externally-recognisable Deerma DX700 and its modification DX700S are virtually indistinguishable to the untrained eye. Both vacuum cleaners are made in a recognizable white body with characteristic controls on the handle. The weight of the devices is about 2.5 kg, which is the average for this segment. However, on closer inspection, you can see nuances in the assembly and materials used.

The ergonomics of the handle on both models are well thought out, allowing you to easily hold the device even during long cleaning. The switch is located in the thumb access area. It is important to note that the mechanism of attachment of the extension tube and nozzles is identical, which makes it easier to find accessories in the event of a breakage or loss of components.

Some users have noted that the plastic in the DX700S feels slightly better, although the manufacturer has not officially announced a change in the supplier of materials, probably due to the tighter fit of parts in the improved model.

• 🎯 Both vacuum cleaners have a swivel head, providing maneuverability around the furniture.
• 🎯 The length of the power cord is 5 meters, which allows you to clean a room with an area of up to 20 square meters without reconnecting.
• 🎯 The design provides the possibility of using manually for cleaning furniture.

Filtration system: cyclone versus sponge

This is perhaps the most important section for those who choose between the DX700 and the DX700S. The base model DX700 uses a simplified air purification system. Inside the dust container, a conventional foam sponge is installed, and its task is to trap large dust, allowing air to pass further, but fine particles can seep through such protection and return to the room.

Model DX700S It's equipped with a full cyclone filtration system, where the air is swirled into a vortex, whereby the dust is separated from the airstream by centrifugal force and deposited in the container. HEPA-A filter that traps microscopic particles, allergens and pollen, and it changes the quality of the air that comes out.

If you have asthma or allergies in your home, the DX700S is a clear choice, and using a simple sponge in the conventional version can cause a cloud of fine dust to rise in the air while the vacuum cleaner is running, which is not only unpleasant, but also harmful to the airways.

💡

Wash it. HEPA-filter with cold water only without brushes and dry it completely within 24 hours before installing it back.

It's also worth mentioning about Maintenance. DX700 It should be washed regularly, but it quickly loses its properties and requires replacement. HEPA-filter DX700S This is a longer service, although it also requires periodic cleaning. Cyclone technology allows the container to retain suction power longer, since the filter pores do not clog instantly.

Suction power and cleaning efficiency

Both models are claimed to have a power consumption of about 600 watts, but the actual cleaning efficiency may differ due to different aerodynamics inside the body. In the DX700S model, thanks to cyclone technology, airflow is less resistant, which theoretically should give slightly better suction performance at the same engine power.

In practice, both vacuum cleaners are excellent at handling animal hair, hair and large debris on hard coatings (laminate, tile, linoleum). For long-pile carpets, the power may be too low, as these are not specialized carpet extractors. However, the suction power of both models is more than sufficient to maintain cleanliness on a daily basis.

An important aspect is to maintain power while working. In the DX700, as the container fills and the sponge is contaminated, the thrust can drop markedly. The DX700S cyclone system is more resistant to loss of performance when filling the dust collector, making cleaning more predictable and faster.

• 🧹 Perfectly collect wool from smooth surfaces thanks to a turbobrush (depending on the configuration).
• 🧹 Effective for cleaning in hard-to-reach places thanks to a narrow nozzle in the kit.
• 🧹 Not designed to collect liquids, which is the standard for dry vacuum cleaners.

⚠️ Warning: Never turn on a vacuum cleaner without a filter or sponge installed, this will cause dust to enter the engine directly and it will quickly fail.

Noise level and energy consumption

Since both are wired, the issue of autonomy is off the table. However, power consumption and noise levels remain important characteristics. The engines in the DX700 and DX700S run at high revs, which inevitably creates noise. Sound pressure levels are around 75-78 dB.

It's quite loud, comparable to a normal vacuum cleaner, and it's going to be difficult to talk on the phone while the device is running. Some users have noted that the engine sound in the DX700S version feels a little softer because of the better aerodynamics of the airflow, but it's a subjective feeling.

In terms of energy efficiency, both devices consume standard 600 watts per hour in their class – not much compared to high-powered full-size models that can consume 2,000 watts or more – and they are justified in saving power.

Comparative Characteristics Table

For ease of perception, we'll put the basic parameters in a single table, which will help you quickly navigate the differences and make an informed decision.

As you can see from the table, the engine's technical parameters and the volume of the dust collector are identical, and the difference lies in the air purification technology, and it is this parameter that determines the target audience of each model.

Services and supplies

The care of both vacuum cleaners is minimal, but it has its own characteristics. In the DX700, the main consumable is a foam sponge. It is cheap, but you have to change it quite often, especially if the vacuum cleaner is used actively. It is more difficult to find original sponges than filters for more popular models.

V DX700S The expended are HEPA-They last longer (usually) 6-12 But, given the improvement in cleaning and health, this overpayment seems negligible. Regular dust cleaning is mandatory for both models.

To extend the service life of the engine, it is recommended to check the condition of the filter elements after each 2-3 If you see that the sponge or HEPA-filter blackened, they must be either washed (if the design allows), or replaced.

• 💡 Always disconnect the device from the network before maintenance.
• 💡 Do not use a vacuum cleaner without a dust container.
• 💡 Keep the device in a dry place, away from heat sources.

⚠️ Warning: Cleaning agents are prohibited when filters are washed, and chemicals can destroy the structure of the filter material and cause an allergic reaction when the next cleaning is done.

Final verdict: what to choose?

Comparison of Deerma DX700 and DX700S, So the conclusion is that the difference between the models is significant, despite the similarities, and if you're choosing a vacuum cleaner for your main apartment, where you spend a lot of time, or if you have children and allergies in the house, the version is: DX700S The overpayment for the cyclone system and HEPA-The filter is fully justified by the quality of life.

Basic model DX700 It has the right to exist as a budget solution for cleaning garages, cottages, workshops or balconies, where clean air is not a priority. №1, and all that matters is mechanical garbage collection, and it's going to do great, but it's obsolete for regular use in living quarters.

Ultimately, it depends on your priorities and your budget, but with health in mind, it's better to spend one time on a more sophisticated filtering system. Xiaomi and Deerma have given us two options for different needs, and ignoring those differences when buying would be a mistake.

💡

Choose. DX700S for living in an apartment because HEPA-filtering, and DX700 Leave for technical rooms or rare cleaning.
