It has been long believed that corded appliances are more powerful and reliable than their cordless counterparts. However, the advancement in battery technology has changed this notion. And the Xiaomi Viomi Aeolus 9 seems to be a good example of a cordless vacuum cleaner that can outshine some of the corded units currently in the market.

The Aeolus 9 is equipped with a powerful DC motor that can deliver up to 100,000 RPM, providing you with enough suction power to lift both large and tiny debris from your floors. In addition to this, it comes with several attachments that can come in handy in different scenarios. It’s also quite versatile and can even be used as a pet vacuum cleaner with the right head attachment.

Moreover, the cyclone separation system prevents pet hair and other debris from clogging the passageway. Since this vacuum cleaner features a tiltable head, you can easily slide it under your sofa and other furniture. Dust bunnies won’t stand a chance against the Aeolus 9’s 120 AW suction power.

With the Xiaomi Viomi Aeolus 9, you will get up to an hour of continuous runtime. However, this may vary depending on the power mode that you are using. There are three power modes that you can choose from when using the Xiaomi Viomi A9 handheld stick vacuum cleaner. That said, you will have full control over this machine throughout the cleaning process.


One-click cleaning

The Xiaomi Viomi A9 has a straightforward power switch that allows for easy operation. You can fire up the DC motor with just one click after which all you have to do is guide the vacuum head to the areas that you want to clean.

Detachable battery

The A9’s 2500mAh battery is removable, so you can easily swap it with a fully charged pack in case it runs out of juice in between the cleaning session.

Unfortunately, the vacuum cleaner only comes with one battery. On the bright side, the battery level indicator will let you know when the battery is about to run out of charge.

Three power modes

When it comes to choosing a vacuum cleaner, always go for models with customisable wind speeds. That way, you can adjust the settings according to your cleaning needs. Well, you will be happy to know the Xiaomi Viomi Aeolus 9 offers three vacuuming modes that you can use on different types of floors.

You can use the max mode, standard mode or energy-saving mode. At max power, the battery will provide you with approximately ten minutes of cleaning time, while the standard mode offers thirty minutes. The third power mode allows the A9 to run for about an hour.

Brushless motor

The Xiaomi Viomi A9 is equipped with a high-quality brushless motor that you can rely on. It requires minimal maintenance and is just as powerful as a brushed motor. Depending on the power mode that is in use, the motor will generate just the right amount of suction force to help you lift dirt and debris from your floors.

LED headlights

Let there be light! This vacuum cleaner features bright LED light that will illuminate the area that you are cleaning. This feature can prove helpful when cleaning under furniture and other poorly lit areas. And because illumination equals visibility, you won’t miss a spot.

Five-level filtering

The Xiaomi Viomi A9 handheld stick vacuum cleaner filter system is designed such that the unit cannot easily get clogged, even when dealing with large debris. It employs the cyclonic technique to ensure the debris is separated from air. The HEPA filter can capture particulates as small as 3 microns, while the metal filter is effective against particles that are no smaller than 0.5mm.

Roller head

Attached to the Xiaomi Viomi A9 is a soft roller brush with high adsorption capacity. The 7mm brush fibres can easily penetrate the gaps on the floor, removing all the dirt. This makes the A9 a great vacuum cleaner for cleaning low-pile carpets.

To boost its performance, Xiaomi has fitted the roller head with an independent motor. This unit comes with three additional nozzle attachments for added convenience. It even has a 2-in-1 brush that you can use for cleaning your laptop keyboard.

It weighs approximately 1.54 kilograms, which is great as this allows for easy maneuverability. Operating this vacuum cleaner is very easy, thanks to its one-click design.

Simply press the power button once and the 400-watt motor will come to life. This is perhaps our favourite feature since it saves you the hassle of keeping a finger on the trigger switch like most vacuum cleaners. Plus, the power button is a thumb’s distance away, making it easy to reach.

But it doesn’t end there; you can pivot the head to the most ideal angle when cleaning hard-to-reach areas. The handle is ergonomically designed for user comfort and also textured to prevent slippage. Unlike most cordless vacuum cleaners that have permanently attached batteries, the Xiaomi Viomi A9 comes with a detachable battery that you can remove when necessary.
