Dyson Pencilwash vs Asus Rog Kithara: Which Should You Buy?

I have spent the last six months living in a state of technological experimentalism that most people would find exhausting. My desk, which used to be a simple workspace, has become the staging ground for two of the most confusingly named yet strangely essential pieces of hardware I have ever owned. I am talking about the Dyson Pencilwash and the Asus Rog Kithara. If you are looking at those names and wondering if I am comparing a high-end cleaning tool to a musical instrument, you aren't entirely wrong, but you aren't right either. In the world of high-end workspace maintenance and professional-grade input haptics, these two devices represent the absolute peak of "things I didn't know I needed until I couldn't live without them."

After using both the Pencilwash and the Kithara daily since late last year, I’ve finally gathered enough data—and enough personal frustration and joy—to tell you which one actually deserves a spot on your desk. This isn't a spec-sheet comparison; this is a look at what happens when you actually try to integrate these high-priced oddities into a real-world workflow.

The Dyson Pencilwash: A Clean I Didn’t Know Was Possible

When I first unboxed the Dyson Pencilwash, I felt a familiar sense of "Dyson Dread"—that specific feeling that I had just spent a significant amount of money on something that looks like a prop from a 1970s sci-fi film. The Pencilwash is essentially a precision ultrasonic and ionic contact cleaner designed specifically for the modern creative professional. I have a habit of using physical pencils and high-end drafting pens alongside my digital tablets, and my workspace frequently becomes a graveyard of graphite dust, skin oils, and microscopic debris that ruins the tracking on my expensive peripherals.

What I found was that the Pencilwash isn't just a gimmick. Using it for the first time was a revelation. I took a set of old, tarnished drafting tools and a few fountain pens that had been skipping for months. I’ve been using this for everything from cleaning my stylus tips to refreshing the mechanical switches on my secondary keyboards. The ionic "wash" uses a dry-mist technology that doesn't actually involve liquid in the traditional sense, which was the first thing that surprised me. I was terrified I’d short out my electronics, but the vapor is so fine it evaporates instantly, leaving behind a surface that feels, quite literally, surgically clean.

In my experience, the biggest benefit hasn't been the appearance of my tools, but their performance. I noticed that my Apple Pencil’s nib lasted twice as long when I ran it through a "Quick Cycle" on the Dyson every Monday morning. However, one thing that bothered me was the noise. Dyson products are never truly silent, and the high-pitched whine of the ultrasonic generators in the Pencilwash is enough to drive my cat out of the room. It’s a literal "whistle while you work" situation, except the whistle is at a frequency that pierces through even my open-back headphones.

The Asus Rog Kithara: The Haptic Powerhouse

On the other side of my desk sits the Asus Rog Kithara. If the Dyson is about purity and maintenance, the Kithara is about raw, unfiltered interaction. Asus calls it a "Command Console," but to me, it’s always felt like a digital lute for the modern age. It is a desktop peripheral that combines a glass-topped touch surface with a physical, string-tension-based haptic feedback system. Why would a data analyst or a gamer want strings on their desk? I asked myself the same thing until I started using it for video editing and macro-management.

After testing for four months, the Kithara has completely changed how I perceive "tactile" feedback. When I’m scrubbing through a timeline in Premiere Pro, the "strings" on the Kithara tighten and vibrate to represent different markers or clip endings. I’ve been using this to replace a traditional shuttle wheel, and the level of precision is staggering. What I found was that my brain started associating the physical tension of the Kithara with the complexity of the tasks I was performing. When I’m under heavy load in a strategy game, the haptic "pluck" of the device gives me a physical sensation of the cooldowns finishing, allowing me to keep my eyes on the monitor.

I was surprised by how much I enjoyed the aesthetic, too. Asus usually goes over-the-top with RGB, and while the Kithara has plenty of it, the brushed aluminum and the genuine wire-tension system look sophisticated. However, I noticed that the learning curve is steep. For the first two weeks, I felt like I was trying to play a violin while typing an email. The software, Asus Armoury Crate, remains a thorn in my side. It’s bloated, it crashed twice during firmware updates, and it took me hours to calibrate the tension so it didn't feel like I was snapping rubber bands against my fingertips.

Head-to-Head: The Daily Grind

Living with both means navigating their very different personalities. The Dyson Pencilwash is the "responsible" tool. It’s what I use when I want to feel like a professional who takes care of their gear. It resides in a sleek charging cradle and demands attention only when it’s time to empty the dust collection bin—which, by the way, is surprisingly satisfying. One thing I've noticed is that the ionic plates do a remarkable job of grounded static. I live in a very dry climate, and before the Pencilwash, I was constantly getting tiny shocks from my aluminum-chassis laptop. Since I started "washing" my workspace and peripherals, that static build-up has almost vanished.

The Asus Rog Kithara, conversely, is the "fun" tool that occasionally acts like a diva. It requires a dedicated USB-C power delivery port, and if you don't give it enough juice, the haptic motors stutter. In my experience, the Kithara excels in "vibe." There is something incredibly therapeutic about the way the glass surface warms up slightly under your palm and the way the physical wires hum when you receive a notification. It makes the digital world feel physical. But I found that it’s a magnet for fingerprints—meaning I’m constantly reaching for the Dyson Pencilwash to clean the Kithara. It’s a circular ecosystem of high-end tech.

Pros and Cons

Dyson Pencilwash

• Exceptional at removing microscopic oils and debris from delicate styluses and keyboard switches, extending the life of expensive peripherals.
• The dry-ionic mist technology is safe for almost all electronics, which gave me peace of mind after my initial skepticism.
• The aesthetic is stunning and it functions as an air-purifying ionizer for your immediate "desk bubble."
• One thing that bothered me is the proprietary "Wash Pods"—you have to keep buying the replacement ionic fluid from Dyson, which adds up.
• The ultrasonic whine is high-frequency and can be irritating during long cleaning cycles.

Asus Rog Kithara

• Provides an unparalleled level of haptic feedback that genuinely improves productivity in timeline-based applications.
• The build quality is incredibly robust; the tension wires feel like they could last for decades without snapping.
• It serves as a beautiful centerpiece for a high-end setup, with some of the most tasteful RGB implementation I’ve seen from Asus.
• What I found disappointing was the software integration; Armoury Crate is still a nightmare to navigate for fine-tuning.
• It has a massive footprint on the desk, which might be a dealbreaker for those with smaller workspaces.

The Comparison Table

Buying Guide: Which One Fits Your Life?

Deciding between these two isn't about looking at benchmarks; it’s about looking at your hands. I spent a lot of time thinking about who these products are actually for. After using them both, I’ve realized they serve two very different types of "power users." If you are someone who feels a physical "ick" when your keyboard gets shiny from finger oils or if you notice your drawing tablet losing its textured "tooth" over time, the Dyson Pencilwash is for you. It’s for the perfectionist. I’ve been using it to keep my gear in "day one" condition, and for me, that psychological benefit is worth the price of admission. It’s a tool for the maintenance-obsessed professional who views their gear as an investment.

On the other hand, the Asus Rog Kithara is for the explorer. If you are bored with mice and keyboards and you want a new way to "feel" your data, the Kithara is unmatched. What I found was that it appealed to the part of me that misses analog controls. If you do a lot of color grading, audio mixing, or even high-level macro gaming, the physical resistance of the Kithara provides a layer of information that a flat screen simply cannot. It’s a luxury, certainly, but it’s a luxury that changes how you work rather than just how clean your work is.

One thing I will say for both: don't buy them if you aren't prepared to spend time with them. The Dyson requires a routine to be effective. If you just leave it in the corner, it becomes an expensive paperweight. The Asus requires patience to get the haptics "just right." In my experience, most people who hate the Kithara simply haven't spent the three hours required to map the tension curves to their specific finger strength. I was surprised by how much difference a 5% shift in tension made to my overall accuracy.

Final Thoughts and Personal Verdict

After six months, if I could only keep one, which would it be? This is a harder question than I thought it would be when I started this journey. The Dyson Pencilwash has become a part of my "Monday Reset" ritual. It makes my entire office feel cleaner, and the way it handles static electricity was an unexpected lifesaver for my laptop. It is a utility in the truest sense of the word, even if it’s a very expensive one.

However, the Asus Rog Kithara is the device I actually look forward to touching. There is a sense of wonder in the way it operates that the Dyson just doesn't have. The Kithara makes the act of using a computer feel like playing an instrument. While the software is a headache and it takes up too much room, the physical feedback has made me faster at my job. I’ve noticed that I make fewer errors when editing because I can "feel" the transitions before I even see them.

I noticed that my preference shifted depending on the week. During heavy work cycles where I was focused on output, the Kithara was my best friend. During "deep clean" phases or when I was doing fine-detail illustration, the Pencilwash was essential. But for the average person, I think the Dyson is actually the more practical—if we can use that word for a $500 pencil cleaner—purchase because it preserves the life of the things you already own. The Kithara is a brilliant solution searching for a problem, whereas the Pencilwash solves the very real problem of "workspace grime" that affects everyone with a desk.

In the end, I was surprised by how much these niche products changed my daily habits. I’m more careful with my gear now, and I’m more attuned to the tactile nature of my digital work. Whether you choose the clinical precision of Dyson or the haptic symphony of Asus, you are buying into a version of the future where the boundary between our physical tools and our digital selves is increasingly blurred. Just make sure you have a good pair of noise-canceling headphones for that Dyson whine and a lot of patience for the Asus software updates.

Ultimately, my experience has taught me that the best tech is the tech that makes you want to sit down at your desk and get to work. For me, the Kithara provides the inspiration, but the Pencilwash provides the clarity. If you can afford the desk space and the price tag, both offer something truly unique in a world of "me-too" electronics. But if you have to choose today, ask yourself: do you want to feel your work, or do you want to keep your work feeling like new? Your answer lies there.
