I made a video on the KAT Nexus Adapter for Meta Quest 3. This one is focused on setup, how it works, and my honest thoughts after testing it. If you want to use KatVR with Quest 3 standalone, this should help you understand what the Nexus Adapter actually does.
Hi! Im Marty. I do a lot of VR treadmill content and have basically used every consumer VR treadmill people care about. Except the Xcelerate treadmill. Im putting out a long comparison review of both the KatVR Katwalk C2+ Enhanced and Virtuix Omni One. This is from my script so apologies for parts that read like it. Its 12 pages long lol.
Here's a video if you dont want to read: https://youtu.be/h0ABqgXyqFc?si=ZRLIEdT\_i\_JLIBld\[
Quick rundown for anyone new to VR treadmills. Both of these treadmills are what people call slide mills. You don't actually walk forward in space. You stay in one spot, your feet slide on a low-friction surface, and sensors translate that sliding motion into "walking" or running or jumping inside the game. You're not on a moving belt like a regular gym treadmill. And we're not quite close to the Ready Player One VR Treadmill. The surface stays still. You are the moving part.
A lot of what they have in common comes from that. Both are bowl-shaped: concave dishes you stand inside of, so the curve of the surface helps pull your foot back toward center after a step. Both come with low-friction shoes that let you slide on that surface without your feet catching. And both have a safety harness that holds you in place so you don't fall when you try to sprint. What's different is how each company puts that together.
The Virtuix Omni One has the slightly deeper, more pronounced bowl. The curve is significant. You're really standing in something. The low-friction shoes are Virtuix's creation the Overshoe which goes over your shoe. The tracking is done by sensors you attach to the shoes. The safety harness is a vest that goes over your shoulders and chest and belt that goes around your waist. The vest clips into an support arm that arcs up and over from behind you when you crouch. Its one of the biggest things that set the omni apart visually.
The Kat Walk C2 Plus Enhanced uses a shallower dish, still concave, but the curve is much subtler. The low-friction footwear is made by KatVR and the computer mouse-like sensors go into the bottom of the shoe. The safety harness is a hip ring that goes around your waist instead of your shoulders, and it locks into a vertical support column that comes up from behind the platform. It also includes a fold-out seat that lets you sit down for seated VR: flight sims, mech games, anything you don't need to be standing for. Or when you want a rest.
Same category, same general approach. Different execution on basically every structural choice. Those differences are going to come up in every category from here on out, so keep that in mind.
Both of these feel like tanks when you first set them up. Serious engineering and a lot of thought went into planning to develop these treadmills. Neither feels like it's going to fall apart on you.
But over time? I've had way more issues with the KatVR. Screws come loose. Parts wear down. I've had to tighten and re-tighten stuff on the C2 Plus Enhanced way more often than I'd like. Now, the repairs are easy. Like, genuinely easy. Parts are accessible, replacements are available, and the KatVR Discord has people who've fixed every problem you'll ever have. But you will be doing maintenance.
The Omni One has needed nothing. Like, literally nothing. It just keeps working. Set it up once and go. I literally just have to make sure I wipe dust off of it. Criminally easy.
Both companies have solid warranties, by the way. So even if something major goes wrong, you're covered on either side.
Edge: Omni One. Less hands-on maintenance to keep it running.
The shoes are one of the most important accessories on either of these treadmills. They're how you interact with the dish, they're where the motion tracking lives, and they're what wears down over time. So they get their own category.
Completely different design philosophies on both sides.
The Omni One Overshoes are Virtuix's own design. They go over your regular shoes, so you keep wearing whatever sneakers are already comfortable for you, and the Overshoes strap on top to handle the sliding. The tracking sensors clip onto the Overshoes and communicate wirelessly over Bluetooth, so nothing is tethered to your feet. Quick tip: if you're a heavier person like me, throw some Hokas underneath. I'll link the ones I use below. The cushion makes long sessions way more comfortable. Took me a few weeks to figure that out. Definitely a me problem, but worth knowing.
The Kat Walk shoes are made by KatVR and use a totally different approach. You wear the KatVR shoes directly and the sensors on the bottom look almost like little computer mice. They read the dish surface optically as you slide. Different tech, different philosophy.
Durability is where the gap shows. My Omni Overshoes have basically not worn much at all. The Kat Walk shoes? I've had to replace them multiple times over the past year or two. They wear down decently fast if you use them a lot, and I use them a lot. On top of that, they get caked up with lube over time and start to get harder to run with, which leads to annoyances when running. That's real money out of pocket on the ongoing basis. We'll come back to that in the price section.
Both are easy to order replacements for. KatVR: order from their store, swap it in, done. Omni One: same deal.
Edge: Omni One. More durable, no ongoing replacement cost. Big win.
Both of these treadmills need to be lubricated with oil to work right. The dish surface and the shoes both rely on staying slick to slide properly. If either gets dry or grimy, you feel it immediately.
Where they differ? A lot.
The lube KatVR includes is terrible. I'm just gonna say it. It gunks up over time, builds residue on the dish, and the gunking actually makes the surface worse to use. After fighting with it for a while, I switched. I use regular treadmill lubricant on my Kat Walk now, the stuff you'd use on a standard motorized gym treadmill belt, and it has been so much better. Cheap, easy to find, works great. If you buy a Kat Walk, plan to throw out the included lube and grab a bottle of treadmill belt lube.
The Omni One's lube is perfect. No gunking, no issues, applies clean, stays slick. The only downside is they don't give you a lot of it in the box. You'll be ordering more sooner than you'd want. Not a huge ongoing cost, just something to factor in.
Edge: Omni One. The included lube actually works.
Honestly? Both of these sound about the same to me. I genuinely could not pick a winner on noise. Both make the "sliding around a low-friction surface" sound. Both are loud enough that your downstairs neighbor will know you're in there like a regular treadmill.
I'm going to drop audio tests of both right here so you can hear it yourself.
If you've got hardwood floors, throw a mat under either of them. Reduces sound significantly. Both communities have recommendations for what to grab.
Edge: Tie.
Cable management and Treadmill Mobility. This category? This is where the Omni One walks away with it.
The Omni One is Bluetooth. There are no cables outside of the power cable which the treadmill could never touch. You strap on the shoes, you step into the bowl, you play. It's beautiful.
The Kat Walk C2 Plus Enhanced has two long cables. And those cables gets in the way. I literally cut my own cable once on accident with the treadmill. [SHOW THE CUT OR REPAIR IF YOU HAVE FOOTAGE] Like, I'm not joking, the cable wraps and I hit it with the platform, sliced it. Had to repair it. Was that a me problem? Sure. But it's also a problem that cannot happen on the Omni One because there's no way it can reach.
Mobility? Same story. Both have wheels on the bottom. The Omni One wheels actually work, and even though the Omni is the slightly bigger machine, it rolls around easy. The KatVR wheels are functionally useless on carpet. You can still push it around the room with a little muscle, but it's not the smooth wheel-it-into-the-corner experience.
Edge: Omni One. Clean sweep.
KatVR uses a hip-ring harness. You step in, ring goes around your hips, locks in.
Omni One uses a vest-style harness. Goes over your shoulders, attaches to the support arm with a included hip harness.
The Omni vest harness is way better than the hip harness, in my experience. It distributes the weight differently, it feels more secure, you can lean and twist without it riding around your body. The hip ring works, and a lot of people prefer it because it's less restrictive, but for me, the vest wins.
Sweat is fine on both. Nothing to call out there.
Edge: Omni One. The vest is the better harness.
Getting INTO the KatVR is faster. Hip harness, click, done. Step out? Same, just unlatch and out.
Getting INTO the Omni One takes a few extra seconds: vest, clip, take brake of shoe, and then unlock the treadmill. But once you're in, you feel way more secure and you have way more movement options. You can lean further, you can move more aggressively, you can do stuff you can't do strapped into the hip ring. You can also crouch insanely easily.
Adjusting for different people? Both adjust well for different heights. But the Omni One is genuinely easier to adjust. You don't have to unscrew anything. Just unlatch and pull up. The KatVR? There's a screw situation. Not bad, but not as fast.
Edge: Tie-ish. KatVR is faster in and out, Omni is faster to adjust between users and more secure once you're in.
Unboxing day, the Omni One is the easy winner. The KatVR has so many screws. It's a real assembly job. The Omni One? Pretty much open the box put the whole pieces together and start playing.
Daily startup? Both are fast. Pop them on, power up, in VR. But the KatVR shoe sensors can be finicky. Sometimes they don't pick up right away and you're standing there going "...come on." The Omni doesn't have that problem because the tracking activates once the tracker is clipped into the shoe. It just works.
Edge: Omni One. Faster initial setup, more reliable daily startup.
Software. Here's the honest take.
The Omni One software is just not very fleshed out for PCVR right now outside of their Omni Headset system. That's the cleanest way I can put it. It works. It's not finished. They're working on it. But if you're buying this to use with your own headset and your own PC, you're going to bump into edges.
That's actually why I built Omni Tune: open source, free, on my GitHub. [SHOW THE TOOL: quick walkthrough video of the interface, 10 to 15 seconds]. It's a GUI for tuning your Omni One motion profiles without editing config files by hand. Link is in the description. Use it if you want. Needs some more updates but I have to make videos for you guys so give me some time.
I also wrote a small SteamVR proxy driver to fix Lighthouse tracking positioning issues. I have 4 lighthouses so people may run into the issue if you're like me. Worth mentioning briefly. Hit me up on discord if you need it. I explained this problem more in my first impressions of the Omni One.
The KatVR software (Gateway app, controller emulation) is more mature on PCVR side honestly. But it has its own annoyances. Random disconnects happen. They're not super frequent but they happen. And the sensor pickup thing I mentioned earlier? Sometimes you've gotta jiggle the shoes to get them to register and may have to restart your game.
Both companies update their software at decent intervals. Neither has gone silent on me.
Both also have very active modding communities. KatVR especially. There are always people coming up with new shoe mods all the time. Omni One's scene is newer but growing fast. They have people come up with ways to support and give tips.
Edge: KatVR. More mature software, more out-of-the-box compatibility. Better for PCVR people outside their system.
Heads up: this is the one category in this whole video where I have to be honest about my limitations.
Both treadmills have a standalone use case. KatVR has the Kat Nexus for Quest-based standalone play. Works great from what I've heard. The Omni One has deep integration with the Omni Headset and Pico standalone headsets. Neither requires a PC.
I have not really used the Kat Nexus. I haven't been a big Quest user in the past few years (I'm PCVR all the way), so I'm not going to fake an opinion on something I haven't used. If standalone Quest support is the deciding factor for you, check out reviews from creators who actually use that side of it. I'm not your guy on that one.
On the Omni One side, I don't mind the standalone implementation at all. I respect it. It's well-built, it works, the experience is solid. But I'm also not going to use it that much because I'm PCVR-first. So most of my Omni time has been hooked into my PC.
That said, the integration between the Omni One and the Omni Headset / Pico is genuinely amazing. Very in-depth. Very fleshed out. If you're someone who wants a fully self-contained "buy this and the headset and just go" experience, the Omni One ecosystem is way more polished than I expected.
One specific thing worth calling out: the business streaming app that the Omni Headset connects to for PCVR is incredibly fleshed out and easy to use. Like, this is the kind of polish you'd expect from a much more mature platform. Plugs in, just works, the interface makes sense. That side of the ecosystem is clearly where Virtuix has put serious work.
And this actually connects back to what I said in the software category: the Omni's software is rougher outside of their headset ecosystem. Inside that ecosystem, it's amazing.
Edge: Not scored. I haven't put enough time on the Kat Nexus side to call it fairly. What I will say is that the Omni One ecosystem with the Omni Headset is the most polished version of the Omni experience overall.
This is where the Kat Walk C2 Plus Enhanced flexes hard.
Literally everything works on the C2 Plus Enhanced, because SteamVR sees it as a VR controller. That's the magic. You can set custom profiles per game. Skyrim VR with Mad God Overhaul? Works perfectly. Contractors? Contractors Showdown? Minecraft VR? No Man's Sky VR? Grimlord? All clean. If a game can take VR controller input, the Kat Walk can drive it. Even UEVR games worked amazing.
The Omni One has native support for some great titles: Half-Life 2 VR, Vertigo 2, Contractors, Fallout 4 VR, GTA San Andreas VR, EXD. And in those games, it's awesome. You do have to connect the controls in SteamVR's controller menu and setup a text file for profiles though. And honestly outside the list Virtuix gives you, you're rolling the dice. The worst thing about the Omni One has been booting up a game and just randomly finding out it doesn't work and there's nothing I can do about it. Then you're back on Steam looking for something else.
Now, a VR treadmill niche the Kat Walk owns is includ a seat that makes playing seated VR like VTOL VR or Iron Rebellion genuinely fun, especially with the bottom haptics turned on. If you're into flight sims or mech games, that's a real perk on the KatVR side that the Omni doesn't have at all.
Edge: KatVR. Massive game library out of the box plus the seat for sim/seated VR.
You can walk and run normally on the Kat Walk. The dish does feel smaller than I'd like, but normal pace movement works.
The Omni One? Running and moving on it is just way easier. By a mile. It's not close. If you want to actually sprint in VR, if you want to chain quick directional changes, if you want to walk backward without thinking about it, all of that is easier on the Omni One.
On a scale of 1 to 10 for raw locomotion immersion, Omni One is a 10. Kat Walk is an 8.5. The Kat Walk is still really good. The Omni is just better at the actual physics of running.
Edge: Omni One. Significantly better movement feel.
Real numbers from my own use.
KatVR: 20 pounds over a streaming season. Daily sessions, mostly Contractors and Minecraft VR.
Omni One: 15 pounds in a month. Sessions when I can. Less total time since I've owned it.
Both work. Both are real cardio. I do about an hour of cardio per session on either one. I show my heart rate on stream which chat loves.
I haven't noticed any discernible joint impact difference between the two. Knees, ankles, back, they've all been fine for me. You can get sore though, especially if you don't stretch. Stretch before, stretch after. Both of these are cardio machines, treat them like cardio machines.
Edge: Both are great for fitness.
Both are great for streaming. I've streamed a lot of hours on both. I even did a whole charity marathon stream on the KatVR.
The usual VR treadmill streaming problem applies to both: if something goes wrong mid-stream, you basically have to get off the treadmill entirely to walk over to your computer and fix it. Neither solves this. It is what it is.
Edge: Tie.
The Omni One is $2,595 core, $3,495 fully kitted with the arm and the accessories.
The Kat Walk C2 Plus Enhanced is $1,598 MSRP and I've caught it on sale for as low as $1,100.
So the price gap is enormous. At MSRP, the Kat Walk is under half the price of a fully kitted Omni. On sale, it's roughly a third.
But factor in the wear and tear. I've had to replace KatVR shoes multiple times and that adds up. That's a real ongoing cost. The Omni One hasn't had comparable wear costs for me.
Also worth knowing: people sell the Kat Walk used pretty often. So if you buy one and decide to upgrade or move on, there's a market.
Both companies have pretty good support. Just make sure you read the returns policy and warranty stuff before you buy, on either one.
Tally it up.
Omni One wins: Build durability, shoes, lubrication, cable & mobility, harness, setup, locomotion feel. (7)
Kat Walk wins: Software maturity, game compatibility, price. (3)
Tie: Noise, getting in and out, fitness, streaming. (4)
Not scored: Standalone & ecosystem. I just haven't put enough time on the Kat Nexus side to call it fairly. (1)
So who buys what.
Buy the Kat Walk C2 Plus Enhanced if:
Buy the Virtuix Omni One if:
To me personally the Omni One is the better treadmill on more of the categories that matter to me. The Kat Walk is a fantastic value and an incredible piece of hardware for the money, but when somebody asks me which one to buy with no other context, I'm pointing at the Omni.
Who should buy neither? If you're not into VR fitness or you don't want to actually run in VR, skip both. Get a chair, get a headset, save the money. These are tools for a specific kind of VR experience. If that's not what you want, neither of these is for you.
