The Keychron K3 Max QMK/VIA Low Profile Wireless Custom Mechanical Keyboard is an ultra-slim 75% compact mechanical keyboard designed for maximum versatility and efficiency. Supporting 2.4 GHz, Bluetooth 5.1, and USB Type-C wired connectivity, it seamlessly adapts to various work and gaming environments. Users can take full control of their setup using the Keychron Launcher web app, which enables key remapping, macros, and custom commands with ease. The LSA (low-profile spherical-angled) keycaps are designed for both Windows and macOS, ensuring a smooth typing experience right out of the box.

Designed for fast-paced gaming and professional multitasking, the K3 Max features a 1000Hz polling rate in both 2.4GHz and wired modes, minimizing input lag for near-instant responsiveness. The Gateron Low Profile Brown switches offer a tactical, pre-lubed feel, delivering responsive keystrokes with medium sound levels, making them ideal for Midway office work and gaming. The keyboard’s hot-swappable version allows users to customize their typing experience without soldering, making it easier than ever to swap switches for a personalized feel.

Powered by QMK/VIA firmware, the K3 Max provides extensive customization options for power users. The ARM Cortex-M4 32-bit MCU with 256KB Flash ensures stable performance, while the IXPE acoustic foam dampens keystroke sounds, creating a quieter and more comfortable typing experience. Additionally, redesigned stabilizers help reduce key wobble, especially on larger keys like the space bar, Shift, Enter, and Backspace, ensuring greater accuracy and consistency. For Mac users, the dedicated macOS layout replicates the Apple keyboard function keys, making it a seamless transition for Apple enthusiasts.

Aesthetically, the K3 Max combines functionality with style, featuring double-shot PBT keycaps for enhanced oil resistance and durability. With 22 RGB backlight effects (plus a white backlight option), users can further fine-tune brightness, hue, and effect speed for a fully immersive experience. The 1550mAh battery provides up to 73 hours of wireless use with backlight off and 42 hours with RGB at its lowest brightness, ensuring long-lasting wireless performance. Compact, powerful, and highly customizable, the Keychron K3 Max sets a new benchmark for low-profile mechanical keyboards.

Game changer..get one!
My floors had varying levels of dirt (think heavy traffic area vs lighter traffic areas) and the detection system masterfully targeted areas until they were super clean. This is a good value, time saving and elevated my quality of life.

Works great, might have to use distilled water if you have hard water
So far it's great! It uses a LOT of water on the first clean (and maybe also because of using the 'Freo' ai mode) you can use tap water, but in areas with hard water, you might need to go through a lot of distilled water. I think on future cleaning jobs it's supposed to use less water though. And you can adjust the cleaning level to a lower setting so that it doesn't use as much. The app takes a little while to get used to, because there are many options and menus. But still very nice to have and use. The vacuum has a dust bin with a very basic filter (needs replaced every 30 days if used), but if you want more of 'Hepa' clean air, you would have to use another type of vacuum before mopping. It also doesn't get close to the edges of some areas for some reason, even thought it could fit. Still, for what it is, it's a great product that will cut down on a lot of mopping time.

Worth every penny. Highly recommend!
To say I love my Narwal robotic mop and vacuum is an understatement—total game changer. I can’t imagine going back to any other robotic vacuum. I have two dogs, including a Jack Russell who sheds like Pig-Pen from Peanuts—basically a walking cloud of hair—and this thing handles it effortlessly. The vacuum + mopping combo is amazing, and it’s so easy to use and maintain. It truly does all the dirty work for me. I did have a small hiccup about two months in, but Narwal support helped me reset it quickly and it’s been perfect ever since (I definitely panicked for a minute 😅). Worth every penny. Highly recommend!

Unreliable. Doesn't work.
Has been every unreliable. Misses lots of spots with horrible mapping. Doesn't go some places for some reason. We moved the furniture, tried remapping but nothing works. Randomly goes in circles in the same spot at times. Updated firmware, spoke to support etc. When using vacuum and Mop option, it skips carpets and doesn't go back to do them afterwards. The whole programming is unreliable. Don't BUY. Can't return it past the warranty/return period.

LOVE ❤️
I’ve only had this for a few days but I am in LOVE with it and maybe a little obsessed. Even my husband commented on how clean our floors were after the first use. The mapping feature works very well; better than my previous robo vac. I love that it takes the everyday maintenance out of the equation by cleaning/drying the mop heads itself. I wish the instruction manual had more info in it, as well as what some of the features on the app entail, but I’m sure google can provide that info. I’m very pleased with this product.
