A few months back, I tested the Roidmi F8 Storm, and it scored high with the cleaning tests I did back then.
The Roidmi NEX is an updated version of the F8 storm with the same set of tools plus an extra attachment – a detachable wet/dry mop that sticks behind the main cleaning head via a magnet.
A Versatile 2-in-1 Stick Vacuum with a Mop
Roidmi NEX Storm
Ten years ago, the idea of a cordless vacuum as a standalone tool for cleaning homes wasn’t possible. Thanks to the advancement in battery technology, what was thought impossible is now a possibility. The Roidmi NEX Storm 2-in-1 cordless stick vacuum is one such option with its 8-cell 2,500 mAh Li-ion battery that Roidmi says will run for up to 60 minutes. It has three power modes designed to maximize run time for different configurations. One feature it has over the Dyson V8 or V10 is the detachable mop that you can use to wet or dry mop. Unfortunately, the mopping feature is only usable in combination with the vacuum head – it isn’t standalone.
- Excellent run time of up to 60 minutes on the lowest setting.
- Push-button switch does not require you to squeeze a trigger to stay on – less strain on the fingers.
- It is a cheaper alternative to the Dyson V10 and V11.
- The sealed filtration system keeps allergens inside the dust cup.
- The dust cup is small – only 4 liters worth of dry dirt.
- Struggles with large debris like Cheerios because of the narrow pathway near the dust bin.
- Special tools needed to remove the battery.

- The verdict
The Roidmi NEX is built upon the concept of interchangeability which gives it its versatility. This vacuum is usable as a cordless stick vacuum or a handheld vacuum depending on the configuration.
It utilizes a streamlined design with the motor and dust bin in the same horizontal plane for maximum efficiency.
The configuration is very similar to the Dyson V11 Torque Drive but the nozzle placement is different from the Roidmi’s with the latter going over the bin rather than in front as seen in the new Dyson cordless vacuum.
It’s got a number of tools that not only will clean floors, but also areas above the floor such as sofas, chairs, mattresses, vents, and much more.
The addition of the flexible hose improves usability inside tight spots. I’d say this is also a good option for cleaning inside your vehicle despite the short crevice tool.
The Roidmi NEX is an upgrade over the F8 storm with the main improvements found in the motor and battery.
Here’s a summary of all the upgrades in the Roidmi NEX storm
- Larger motor: The newer NEX variant comes with a larger 435-watt motor that produces 145 air watts (or AW) while the older F8 storm has 415 watts or 115 AW.
- Longer lasting battery: Roidmi also put in a larger 8-cell Li-ion battery that will run for up to 60 minutes using a non-motorized tool.
- Mop tool: It also comes with a wet/dry mop tool that sticks on the back of the main cleaning head using a magnet. So with this tool in place, it is usable as a wet or dry mop. Unfortunately, the mop can’t be used by itself.
- Middle power setting accessible with the switch: In the older Roidmi F8, the middle setting is only accessible using the app, but that’s no longer the case with NEX as all three modes are available with the switch.
- Detachable battery: The NEX battery is removable and is easily replaced.
The Roidmi NEX only has one main cleaning head with two interchangeable brushes.
It comes with the soft roller brush and the standard beater bar.
Even if it does not have a brush roll on/off feature, it works as well on bare floor as it does on carpet.
This variant can clean thoroughly on bare floor because it has decent clearance that allows large bits of debris to fit.
Similar to the Dyson V10 and V8, the Roidmi NEX comes with a soft roller tool that works best on hard surfaces.
The biggest strength of this tool is its ability to pick up even large debris that most other stick vacuums with standard cleaning heads won’t be able to accomplish.
Roidmi says that this tool is water-resistant, so it is usable in combination with the mop. But don’t use this to clean anything wet or you’ll risk damaging the motor and voiding the warranty.
Carbon fiber roller brush
This tool has a combination of soft, carbo fiber bristles, and a blade type brush that will provide great agitation on carpet.
The soft bristles are excellent at picking up fine dust, while the rubber blades tackle the larger particles of dirt with ease.
Both brushes will do equally well on both surfaces so unless your home only has bare floor; it would make sense leaving the bristled brush attachment on instead of continually switching.
Aside from the two brush attachments, the NEX also comes with a mop attachment. This tool utilizes a magnet to fasten itself behind the main cleaning head (see photo above). It has a water tank (180-milliliter capacity) that you can use to dry or wet mop to complement the soft roller brush’s water resisting properties.
Aside from the main cleaning head, it also has other tools for above-floor cleaning like the combination crevice/brush tool and mini turbo brush.
For extra range, the NEX Storm also has a flexible hose tool for those hard to reach spots.
Here’s the complete toolset
- Crevice tool: for cleaning tight spots and crevices between seat cushions or seats inside the home or vehicle.
- Brush tool: this is great for cleaning ceiling vents, keyboards, or Venetian blinds. This tool is an extension of the crevice attachment.
- Mini turbo brush: this is an excellent tool for cleaning pet hair or embedded dirt on fabric upholstery or mattresses. The pivoting head allows it maximum traction on the surface during the back and forth pass.
- Flexible hose: it adds reach to the attachments, but it isn’t usable with the mini turbo brush since it does not have any contact points for current. When fully stretched, the hose measures just a little over 32 inches long.
- Mop attachment: this is great for dry or wet mopping floors. This tool sticks behind the main cleaning head using a magnet. It’s able to store up to 180 ml of water for light mopping tasks. I wouldn’t recommend using this as a replacement for a traditional mop.
- Extension wand: with this attached, this vacuum is usable as a stick vacuum.
- User manual: only available in Chinese right now.
- NEX vacuum: the main unit where the motor, dust bin, handle, and filters are located.
- Main cleaning head: has two brush attachments – the soft roller bar and carbon fiber brush.
All these tools translate to a versatile cleaning tool that can clean floors, sofa, rugs, carpet, and all sorts of upholstery.
Roidmi says that this cordless stick vacuum will run for up to 60 minutes in the low setting using a non-motorized tool. In boost mode, it’ll run for up to 38 minutes and 10 minutes in the max mode.
Those numbers are impressive, so I decided to test it out how it runs using a non-motorized and motorized tool and see how long it can go.
|Main cleaning head||61:34 mins.||29:06 mins.||12:07 mins.|
|Non-motorized tools||67:45 mins.||31:50 mins.||12:09 mins.|
For the test, I charge and run the vacuum with the main cleaning head, mini turbo brush, and a non-motorized tool until it shuts off with a timer right beside it in different power settings.
Take note that there is a margin for error in the tests that I do. But these numbers represent how long this vacuum will run in the real world.
Roidmi says that the battery is detachable from the unit, but you’ll need a special hex tool to remove the three bolts holding the orange cover.
Replacement batteries aren’t available so far but will be in the future.
To see how well the Roidmi NEX performs, I’ve put it through several cleaning tests to measure how it does at cleaning different types of dirt on carpet and bare floor on varying types of trash from fine to large debris.
I used different types of debris, such as Cheerios, coffee grounds, and quaker oats. On hard floor tests, I scattered 30 grams of coffee grounds, quaker oats, and Cheerios. On carpet, I used 50 grams of coffee grounds for both the surface and deep cleaning tests.
Carpet (Surface Pickup)
Carpet (Deep Cleaning)
The results on bare floor are skewed because of the failure of the NEX to clean Cheerios effectively. Taking away the results of the Cheerios test, the score would have been 94.68.
Bare floor cleaning
Regardless of the brush, the Roidmi NEX excels in vacuuming bare floor. In several tests I’ve done, it was able to pick up a perfect 100% of coffee grounds and quaker oats.
If there’s anything that the Roidmi NEX struggles with, it’s large debris like Cheerios. This is due to the design of the vacuum and not the lack of power.
Rubbish passes through the extension wand and then a narrow opening right before going inside the bin.
The narrow opening is a bottleneck of big stuff bundles up together.
It also did well with cleaning dirt with surface dirt pickup on low pile carpet, picking up 98% of coffee grounds.
In the deep cleaning test, it was able to pick up 47 grams out of 50 or a 94% score.
I didn’t bother doing the cheerios tests on carpet because of the clogging issue during the test on bare floor.
One of the most evident upgrades that the NEX has over the F8 is the addition of a mopping feature.
Roidmi heavily advertises this in their Kickstarter add so I decided to find out if it really works.
Watch this video and see for yourself.
Yes, it was a huge mess but that’s the impression I got when I first saw the add.
The stuff I tested it on were common household stuff like ketchup and soy sauce.
I did this experiment to see the potential issues if it would suck in the debris and it did all the way to the dust cup.
Imagine cleaning a bowl full of cheerios and milk as seen in the ad, cleaning the vacuum itself would be harder.
I’m not sold on using it as a replacement for a dedicated hard floor cleaner built for the task.
The mop itself is small and the risk of damaging the main floor tool to great to make it worthwhile using it as such.
Next, let’s look at the usability of the Roidmi NEX. We’ll go through several important features that affect it.
One strong point of the Roidmi NEX is its looping handle that extends beyond the motor. It’s designed such that you can hold it at different angles so there’s less pressure on the wrists.
However, since the motor and dust cup is on top, you can still feel the weight mostly on the wrist.
Unlike the Dyson V10 or V11, it does not use a trigger switch. Roidmi designers opted to use a push-button switch that doesn’t require constant squeezing.
There are two switches. The first one at the top of the battery near the indicator lights is the power switch. You can also use it to toggle through the different power modes and hold it for a few seconds to switch off.
A second switch found at the back of the handle near the exhaust vents is the button that toggles through the different power settings.
People who want something that doesn’t require squeezing a trigger would benefit from this product.
Moving around and under furniture won’t be an issue with this vacuum thanks to the swivel steering.
The extension wand almost goes flat, so it can reach deep under furniture.
Emptying the dust bin
To empty contents, the dust bin has to be detached from the body. It’s simple – just push a button in front of the bin to release the lock.
One the dust cup is out, twist the top cap to remove the filter assembly then empty the contents.
Magnetic wall mount
Unlike the Dyson V10 that uses a bulky wall mount, the Roidmi NEX utilizes something more compact. There are two options to mount – using double-sided tape or screws.
The mount also doubles as a charger. So you have the option of the cable on the mount rather than the vacuum itself.
This prevents instances when you accidentally detach the vacuum with the plug still on.
The primary thing that needs to be taken care of for any vacuum is cleaning the filter.
I asked a representative from Roidmi if the filter is washable and the replacement cycle. She said that the filter is not washable and needs to be replaced every three to six months, depending on the environment, usage, and amount of dust.
A pack of six filters will cost around $35 in Amazon (that includes shipping), so if you replace it once every six months, you’ll only have to spend $8.75 annually on replacement filters. On the high side (or replacing filters every three months), the annual cost doubles to $17.5.
One way to extend the service life of these filters is to use a brush to dislodge dust or a handheld vacuum with a brush tool to do the task.
At the moment, the Roidmi NEX isn’t available in major American online stores such as Amazon. The only place you can purchase this would be in Aliexpress, and it’ll cost just under $450 – still cheaper than the Dyson V10.
The bigger question mark for me would be the availability of parts such as the battery and filter over the long term.
Only time will tell if Roidmi delivers on its promise, but if you look at the earlier version, the F6 Storm, parts like the filter are available.
Roidmi says that they back up their product with a 2-year warranty and free lifetime customer service.
5 reasons why you should buy the Roidmi NEX
- Exceptional run time: The 8-cell Li-ion battery surpasses the 60-minute figure (61:34 mins to be exact) that Roidmi claims it has and that’s in the lowest power setting using the main cleaning head.
- LED headlight: This feature dramatically helps with visibility when cleaning under furniture.
- No squeezing needed: One complaint I’ve heard from Dyson owners is the need to squeeze the trigger continuously. This won’t be an issue with the buttons in the NEX that stays on.
- Powerful motor: The new “Engine-X brushless motor” spins up to 120,000 rpm and generates 145 AW of suction.
- Six-stage filtration: Roidmi has six layers of filtration starting with the metal mesh filter and ends with a post-motor HEPA filter.
Roidmi is slowly closing the gap between itself and the Dyson with the improvements in their second-generation NEX variant.
Even with the main cleaning brush attached, it exceeds the advertised 60-minute run time by over a minute.
The toolset that comes with this variant is pretty generous. My favorite attachment would be the hose because it extends the reach of the non-motorized tools.
There will be other issues such as the small size of the dust cup and the need for a special tool to remove the battery and the second HEPA filter.
But overall, this is an excellent product that does the job with efficiency.
The biggest question mark right now would be the availability of parts such as the battery and filters.
Is This New Xiaomi Product Better Than The Roidmi F8?
- Ergonomics - 90%90%
- Surface Cleaning - 84.25%84%
- Quality - 95%95%
- Design - 90%90%
- Value - 89%89%
- Deep Cleaning - 76.8%77%
The Roidmi NEX Storm like the F8 is an above-average stick vacuum very capable of cleaning surface dirt on a variety of surfaces. Surprisingly, at least for me, the NEX is less potent than the F8 in terms of airflow but it’s less noisy. The mopping attachment will not work on heavy spills but will do a decent job on the lightest messes. Thinking that it will replace a standalone mop will be a mistake.
