Krapof Auto Clean Self Empty Slim Vac review

The first I heard of Kleva Range was earlier this year, when a colleague mentioned it has a heck of a lot of home appliances and kitchenware in its catalogue. As a floorcare expert, the Krapof Auto Clean Self Empty Slim Power Vac caught my attention, especially since it listed an industry-leading spec — a whopping 450AW of suction, which beats out Samsung Bespoke Jet AI Ultra with its 400AW. Other powerful cordless stick vacuums I've tested are the Dreame Z50 Station with 330AW of suction, while the Dyson V16 Piston Animal has 315AW.

With the Krapof (surely that's a tongue-and-cheek take on a name?), it's not the suction that stands out, but how compact and lightweight it actually is. The vacuum weighs 2.3kg with the floorhead attached, while the self-cleaning docking station adds just another 5kg. That's a very lightweight package. It's also very compact, with the appliance taking up an area of just 25.5cm x 21.7cm — about the same footprint as Samsung's Clean Station but smaller than Dreame's Z-series auto-emptying docks or some free-standing docks like Dyson's.

While the Krapof Slim Vac (as I shall call it from here on in) is quite short, even for short people like me (I stand just five-feet tall), thankfully the wand is telescopic and should suit most people.

Otherwise it's not all that different from so many other self-emptying stick vacuums on the market. However, unlike many of them, the dock has options for you to set auto self-emptying when the stick vac is placed back for charging or trigger it manually, although the former didn't always work during my testing, requiring me to press the Start/Stop button on top of the dock.

You can, however, empty it manually as well as directly into a bin if you wish, which could save you cash in the long run on buying replacement dust bags — just keep the self-emptying function in the dock turned off and press a button on the lower part of the dust canister in the handheld unit to lower the trapdoor.

You can also clean out the inside by twisting the top to remove and access the filter. Dismantling fully isn't the easiest task, though, but it at least means you can maintain the vacuum well to increase its lifespan and keep it in tiptop condition.

One thing to note about the stick vacuum while it's docked and charging is that the top display will be upside down when you stand before the appliance, but it's fine when you take off the dock to use. So if you see the percentage sign of the battery indicator before a number like 85, assume it means it's a 58%.

What I do appreciate about the self-emptying charging station is that it has dedicated space to store the two extra attachments that ship with the vacuum (a crevice tool and a brush) — they just clamp onto two stumps on the side of the dock's base.

The Krapof Slim Power Vac has three suction settings, which can be accessed by pressing the +/- icon on the touchscreen when needed, but in its default Auto settings, dynamic suction sets in and the power increases or decreases depending on how much dirt the vacuum senses. The change in suction in denoted by the colour of the Krapof logo on the front of the handheld unit, going from green to blue to red as you shift from lowest to highest power settings.

Interestingly, despite claiming to have a whopping 450AW of suction, the Krapof Slim Power Vac is not very loud and, to be honest, it doesn't even perform as well as the 400AW Samsung Bespoke Jet AI Ultra or the 280AW Dyson Gen5detect. I suspect a lot of that has to do with the overall design of the stick vacuum, which also means its disappointing performance is down to a floorhead that tends to scatter visible particles, even those as small as chia seeds.

So while it's perfectly good for invisible dust, other household spills like cereal (even small bits of oats), tea leaves, grains of rice or other dry spills get pushed around by the edges of the floorhead (as you can see from the video below). That means you're cleaning parts of the floor you've probably already vacuumed, doubling your work and making cleaning more of a chore than it really ought to be.

The scattering happens on both hard floors and carpets, so it's really not dependent on floor type and definitely got to do with the design. Furthermore, the floorhead's best suction is the forward motion, which is disappointing given its price tag and the fact that other models that cost about the same can suck equally well when moving front or back.

The floorhead has headlights built in, but they're not very bright and, in a well-lit room, aren't useful at all. Even under furniture, I didn't think the lights helped illuminate dust but highlighted long-forgotten lost items under furniture.

Another disappointing aspect of the main floorhead is the amount of hair and fur that gets entangled in the bristles. So if you have pets, I definitely wouldn't recommend it. That said, if you exclusively have just hard floors, a separate roller is included in the box that can be used in the floorhead to avoid bristle damage if your wood floors are sensitive, and this minimises the entanglements, but you will need to clean out the brush if you use the main floorhead as your primary cleaning tool.

This also means that your regular maintenance of the appliances increases as performance will be affected if you don't keep the floorhead free of human hair and pet fur.

As disappointing as I may have found the scattering of dirt and the hair tangles, battery life at least is quite standard here. Depending on how often dynamic suction gets triggered, you can eke out about 35 minutes of vacuuming on the default Auto mode, but if it's just daily dust, you can get a more with the LED floorhead attached.

This matches Kleva's claims of getting up to 30 minutes on the 'standard' setting, but switch to the non-motorised attachments and you'll get up to 80 minutes on the lowest Eco power setting.

Decent battery life, however, does not make up for the fact that this vacuum cleaner, while fine for some basic tasks, will struggle and make you work harder rather than easing the task of cleaning your floors. At the end of the day, I found it to be a frustrating experience overall and, for its price, find it hard to recommend over options like the Samsung Jet 95S or the Shark PowerDetect Clean & Empty if you really want a self-emptying option. In fact, I would even recommend a discounted Dyson V8 Cyclone and the additional purchase of the Auto-empty Dok. Despite lower suction, any of these three will offer a much smoother experience.

What surprises me even more is the number of glowing user reviews online, but the vast majority on Product Review seem to be incentivised ones, so please don't fall for the hype.

Krapof Auto Clean Self Empty Slim Vac review: price & availability

• Only available directly from Kleva Range
• List price of AU$899 but usually discounted to around AU$649

For a stick vacuum that claims to offer industry-leading suction and a self-empty function, the Krapof Slim Power Vac is well priced even at its RRP of AU$899. However, it's only directly sold via the Kleva Range website and is typically available with a discount that saves you AU$250.

However, given its design flaws that affect the overall user experience, even the discounted price of AU$649 is a bitter pill to swallow as you can opt for a lower-specced and more reliable vacuum for about the same price or lower.

Take, for example, the Dyson V8 Cyclone which, with its 150AW of suction feels overpriced at AU$649 and no self-emptying. However, it regularly drops to around the AU$450 mark, then add on the cost of purchasing Dyson's Auto-empty Dok for about AU$250 and you'll get just as good a clean with a much easier vacuuming experience for AU$700.

Shark has a lot of options too, all of which have lower suction than what the Krapof lists in its spec sheet, yet do a better job. In fact, the Shark PowerDetect Clean & Empty can be had for around the AU$650 often on Amazon, giving you a self-emptying charging dock that doesn't even need replacement dust bags.

If I had to score the Krapof on value alone, it'd be a rather low number.

How I tested the Krapof Auto Clean Self Empty Slim Vac

The Krapof Auto Clean Self Empty Slim Power Vac was tested in TechRadar's Sydney office which has large open spaces of hard floors and low-pile carpet. While regular dust suction was tested every two days on hard floors where particles are more visible then on darker carpet, I also used mixtures of various pantry staples to emulate different particle sizes. Tea from a bag is fine dust, while chia seeds are small. Along with them, I added in quick-cook oats which are smaller than regular rolled oats, plus pieces of freeze-dried raspberries.

One of my colleagues also kindly brought in fur from her two dogs for me to test this vacuum for pet households, which I scattered on both the hard floor and on the low-pile carpet in the office.

Battery tests were conducted with the main motorised floorhead with dynamic suction and without by leaving the machine running in one spot. The latter was also done using the crevice tool attached to the handheld unit.

Boox Go 10.3 Gen II Lumi: One-minute review

As far as epaper writing tablets go, Boox has some of the most versatile options thanks to their Android-based operating systems, and the Boox Go 10.3 (Gen II) Lumi is arguably the best of them despite its rather mouthful of a name — I’m just going to call it the ‘Lumi’ from here on in.

I was already a fan of the original model, calling the reMarkable dupe a pleasure to use in my Boox Go 10.3 review — and by just adding a light and making the battery consumption more efficient, the Chinese ereader maker has made the Gen II model better.

Despite the screen being a touch slower than I’ve experienced with other devices like the 2024 and 2025 Kindle Scribes, the light adds a lot of contrast to the screen, making it easier to read on, whether that’s an ebook or a handwritten note. Now, I have to mention that there is a Gen II without a frontlight as well but, in my opinion, having the screen lit up just makes the epaper writing tablet that much more usable in any situation. With a frontlight, it also becomes a true Kindle Scribe alternative — again, thanks to its Android-based OS that gives the user access to the Google Play Store.

However, the aforementioned slow display is a disappointment as every time I woke up the Lumi to read or write, there would be a couple of screen refreshes (clearly marked as ‘Rendering’ when directly waking up to the native library application) before it settled down. Page turns, though, are fine but, again, Amazon’s 2025 Kindle Scribes are just that little bit faster at this as well. Long story short, screen performance doesn’t seem to have improved over the Gen I Go 10.3.

While I can live with the slower screen, I can’t fathom why Boox would retire the stylus that came with the original Go 10.3 as it was a lot better than the supplied InkSense Plus pen. The new stylus isn’t as smooth to write with, and is heavier, detracting from the all-important writing experience.

So as much as I’d love to say the Lumi is an improvement over its predecessor — and it is in a couple of ways — it just seems like Boox has taken two steps forward (with the frontlight and battery life) but one step back with the stylus.

Boox Go 10.3 Gen II Lumi review: price & availability

• Announced March 2026
• List price: $449.99 / £429.99 / AU$729
• Available directly from the Boox Shop and third-party retailers

With the addition of the frontlight, the price of the Boox Go 10.3 (Gen II) Lumi is a lot higher than the launch price of the original Go 10.3 — you’re looking at shelling out $449.99 / £429.99 / AU$729 for the former, which is about $70 / £50 / AU$120 more than what the latter was when it was released in 2024.

That’s quite steep, although considering how expensive every bit of tech is getting thanks to RAM shortages, I’m not really surprised. It’s still competitively priced considering the 3rd-generation Amazon Kindle Scribe (2025 release with frontlight) retails for $499 / £449.99 / AU$849 for the 32GB flavor, while you get double the storage with the Lumi. Throw in the versatility of Android and it’s arguably better value (even compared to any of the reMarkables), but given its overall performance and user experience compared to the competition, I’d be hesitant to recommend it.

If the frontlight isn’t important, you can opt for the Gen II version without it, which will set you back $419.99 / £399.99 / AU$689. Prices for both Boox Gen II devices include the InkSense Plus stylus and a magnetic sleep case.

Boox Go 10. Gen II Lumi review: specs

Boox Go 10. Gen II Lumi review: design & display

• Good-looking, lightweight epaper tablet, but clunky stylus
• 10.3-inch E Ink display with good contrast
• Textured rear panel adds good grip

With its eggshell-white body and metallic trim, I thought the first-gen Boox Go 10.3 was a pretty tablet, so I’m glad to see that the Gen II version hasn’t been changed — except for a slightly more textured rear panel that affords a little more grip, which is important for a slim device like the Go series slates. I should note here that both Gen II Go 10.3 tablets are identical physically but, without LEDs on the unlit version, it’s about 14g (0.5oz) lighter.

While the slimness doesn’t make for fantastic ergonomics, the Lumi weighing only 364g is, in fact, lighter than the Gen 1 model that tipped the scales at 375g without screen lights. It is about 0.2mm thicker than the previous Go 10.3, but that’s neither here nor there.

It’s still a beautiful device and, despite the thinness, there are dual speakers on either side of the USB-C port on the bottom edge, as does a mic. The only button is for power/sleep on the top edge. There’s no microSD tray here, though, for additional storage. One larger bezel allows plenty of room for your hand, although holding such a slim device, no matter how light, isn’t necessarily ergonomic. If you add in the sleep case, however, it just becomes heavier.

I should talk about the case here, really quick — it’s a faux suede cover that unfortunately comes with the removable flap that I utterly detest. The brown suede material starts to lose its luster within days of use, so I can’t attest to its longevity, but I can’t fathom why Boox has to make the magnetic flap removable. This has been the case with the last few Boox devices I’ve tested and I find it rather annoying — the magnet is quite strong and the flap tends to entirely come away when you unfold it to close the case or secure the stylus to the side of the tablet.

Speaking of which, the magnetic hold of the stylus is good but, as with nearly every such device, it’s not strong enough to keep the pen secure during travel, so you do need to depend on the case.

Boox has also changed the pen, now offering the InkSense Plus stylus that has a thicker tip that just isn’t as smooth as the previous stylus. It’s also slightly heavier than the older pen, which makes it feel clunky in the hand that, in my opinion, doesn’t lend itself well to controlled mark making on the screen. And as I’ve discussed elsewhere, the stylus can make or break the user experience for epaper tablets. Sadly Boox is moving away from using EMR support on its screens (just like reMarkable), so you can’t use a third-party pen on the Lumi.

Boox hasn’t revealed what E Ink screen technology it’s using here, but the 10.3-inch display isn’t bad, with a 300ppi resolution. It’s not as yellow (warm) as I’ve seen on other Boox devices and the frontlight’s incremental adjustments for both brightness and temperature are excellent, adding wonderful contrast to the text or writing on the screen that makes the Lumi a far better reading tablet than its predecessor.

Boox Go 10. Gen II Lumi review: Software

• Runs a custom Android 15-based operating system
• A relatively clean user interface, but it takes getting used to
• Plenty of good native apps, but access to the Google Play Store makes it very versatile

Where the original Go 10.3 released in 2024 was using Android 12, the Lumi (and its cheaper sibling) have been upgraded to Android 15, although the software is a very trimmed-down custom version of Google’s operating system. You still get unfettered access to the Google Play Store, so you can, in theory, use any Android app, but e-ink tablets weren’t meant for streaming content or playing games on.

That said, nearly every Boox device comes pre-loaded with native apps that are quite good in their own right and have been improved over time as well, making them more streamlined than before. That’s not to say the UX is easy — if you’ve never used a Boox device before, it will take time to wrap your head around it all as there are still little adjustments that are hidden in sub menus.

What’s different with the Go series compared to other Boox tablets is the home screen navigation — the main menu is arranged vertically on the left, with the Library being your default view. You can change the main menu items in Settings, though, either adding or removing applications.

Customizing the user experience has never been Boox’s problem, which means you can choose between several options for System Display or Gestures, and even tweak individual native apps as you see fit — even the NaviBall is optional to use and can be configured to trigger a plethora of functions.

The Control Center hasn’t changed much over the last couple of years, but I’m still not sure access to an AI assistant is necessary on an e-ink device, but perhaps some power users would appreciate it.

As always, you can sign into a fair few cloud services, including Google Drive and Dropbox, get full support for EverNote and OneNote, or download any other productivity application you might need, but keep in mind that not all third-party apps will be optimized for this device.

One of the things I really like about Boox’s premium note-taking tablets is OTG (on the go) support. This means I can plug in an external hard drive or portable SSD directly into the USB-C port to transfer files. In fact, it’s what I predominantly use even though BooxDrop is a handy app for cloud transfer. I don’t even bother signing into my Google Drive account on a Boox these days.

There really isn’t very much to complain about from a software standpoint — it’s the writing experience that takes a tumble here.

• Software score: 4.5 / 5

Boox Go 10. Gen II Lumi review: User experience

• Good screen contrast with lights makes for a lovely reading experience
• The supplied pen, however, isn’t as nice as the older version for writing

A device might look lovely and come with the nicest software, but ultimately its user experience determines its value. And that’s the case with the Go 10.3 Gen II Lumi — it does a lot right, like its reading experience is lovely, but its main functionality of writing is a little bit of a letdown.

Reading

Like I said, reading on the Lumi is lovely — the frontlight makes the text stand out, adding contrast where previously, on the Gen 1, it was disappointing. Page turns are quick enough too with the screen quite responsive to taps and gestures.

And yet I feel it’s a little slow for an epaper tablet that was released in 2026. For example, every time I woke up the Lumi during my months-long testing, it took a while to ‘render’ an ebook from its native library app.

It very much seemed like it was refreshing the app twice before finally rendering the page. On the other hand, the 3rd-generation Kindle Scribe released in 2025 takes a second or two to open but doesn’t flicker or ‘refresh’ the page — it’s a lot smoother on waking up. As are the Kobo Libra Colour and Kindle Paperwhite from 2024.

Boox doesn’t reveal what E Ink screen tech its using, but other than its slight slowness on waking up, I can’t complain about the reading experience. All books and images rendered on screen have been sharp and clear, particularly with the frontlight on.

Writing

The same kind of contrast with the frontlight on is available on the Notes app too where handwriting looks sharp and clear on screen. However, the physical act of writing on the Lumi isn’t as good as it has been on the Gen 1 because Boox decided to change the stylus.

The previous pen had a thinner nib that moved over the screen quite well. The new InkSense Plus stylus is heavier and the slightly thicker tip feels like it needs to be dragged to make a mark — it feels clunkier in comparison.

Boox has also stepped away from using EMR screens, which means you can’t swap that pen out for another. I tried using one of Boox’s own older pens (used to be supplied with the Note series) and it didn’t work. That’s a real shame as writing is the Lumi’s principal function and the experience of doing so is disappointing.

The native Notes application, though, is full featured — in fact, for the average user it’s probably overkill — and would be ideal for students, teachers and researchers.

• User experience score: 3.5 / 5

Boox Go 10. Gen II Lumi review: Performance

• Generally good performance except on waking up
• A lot of ghosting visible, especially in the Notes app
• Exceptional battery life for an Android device

The Lumi's overall performance is a mixed bag. While it uses a better chipset (Qualcomm Snapdragon 690) compared to the original Go 10.3 (Snapdragon 680), it hasn't really made much of a dent in the speed with which the Lumi performs the tasks at hand.

That's not a complaint — it's an observation. However, Amazon's newest Kindle Scribes are just that much faster at things, like page turns are so quick they barely register that they've moved and the lag between pen input and the mark on screen is barely discernible. On both counts the Lumi is just that smidgeon slower that you can notice if you use it side by side with the 2025 Kindle Scribe (3rd generation).

The slow waking up of the screen is also something that has bothered me, and I've already mentioned how disappointing the writing experience is, but I'm also surprised at how much ghosting there still is on Boox devices, including the Lumi, something Amazon has managed to completely eliminate on its Kindles. You'll be able to notice the ghosting on nearly every single image I have in this review (including in the gallery below).

Where the Lumi really shines (pardon the pun) is with battery life. It still uses the same 3,700mAh battery pack that was in the Gen 1 model and yet whatever software adjustments Boox has made has pushed battery life to weeks rather than days. It's the first Android digital notebook I've used to have such an impressive battery life, one that can match the Kindle Scribes, albeit dependent on use.

In my case, an hour of reading and 30 minutes of writing per day gave me 17 days of use with frontlight at medium brighness and a similar warmth setting, plus Wi-Fi on at all times (but not Bluetooth). Using cloud services and didn't make any dent on the battery usage, although excessive online browsing did drain a little extra but not by all that much.

Topping up was average, with the 3,700mAh pack going from 19% to full in just under two hours when plugged into a wall charger via a high-quality USB-C cable.

• Performance score: 3.5 / 5

Should I buy the Onyx Boox Go 10.3 (Gen II) Lumi

Buy it if...

Don't buy it if...

Also consider

I like the Lumi, but I don't I love it. If, like me, you'd be keen to check out other options, the two below are the ones I'd recommend, both of which are cheaper but aren't Android based.

How I tested the Onyx Boox Go 10.3 (Gen II) Lumi

I've tested a range of ereaders and epaper writing tablets for TechRadar, so I'm well suited to compare the Boox Go 10.3 (Gen II) Lumi with its competitors.

As with all such devices I've previously tested, the first thing I did with the Lumi was to sign into the Google Play Store and down the Kindle and Kobo apps. I then used OTG support to transfer ebooks to the device directly from a portable SSD via the USB-C port, but I also used BooxDrop and cloud transfer from Google Drive to test various services.

The Lumi then became my daily ereader and note taker for 4 weeks, using it an average of 2-3 hours a day to read and write. I'm not an artist, so drawing was out of the question.

Out of curiosity, I also downloaded Geekbench 6 to benchmark the CPU (the app is available on the Play Store). I sideloaded a few MP3 files to test the onboard speakers.
