INTRODUCTION OF K MODES
K1000 Full SubGHz (Coming in ExpressLRS V3.5)
- Yes, you read that right—1000Hz in the 868/900MHz domain! While this mode is designed for maximum data throughput when used with MAVLink, don't let the 1000Hz fool you; during development, it was tested for long-range performance.
DK500 (Coming in ExpressLRS V3.5)
- Designed specifically from the ground up for speed enthusiasts and RC reliability. K modes are next-generation FSK modulation with built-in packet repair (Forward Error Correction). Similar to FLRC D500, DK500 sends repeat packets to minimize packet loss in challenging race environments. Paired with a Gemini-enabled Tx and Rx, nothing compares to its RC reliability.
NEW PACKET RATES
Sub-GHz 200Hz Full (-111dBm)
- Optimized for MAVLink: Double the packet rate of current 900MHz SX1276 hardware, tailored specifically for MAVLink users to provide a more robust link and reduced interference.
Dual Band X100Hz Full (-112dBm)
- Enhanced Gemini Mode: Enjoy dual-frequency transmission with a 100Hz packet rate and full 16-channel resolution, ensuring strong and stable connectivity even in challenging environments.
Dual Band X150Hz (-112dBm)
- Gemini Mode: Experience simultaneous sub-GHz and 2.4GHz transmissions, offering robust performance and reduced interference with a packet rate of 150Hz.
Sub-GHz 250Hz (-111dBm)

Great all-in-one steam cleaner
Size: Standard
The Schenley 19-in-1 Steam Mop is super versatile and easy to use. It heats up quickly and the steam is strong enough to clean floors, grout, and bathroom surfaces without any chemicals.
I love how easily it switches to a handheld steamer—feels like multiple tools in one. The build is sturdy and it maneuvers well.
Overall it’s a great value and works really well.

Great Lightweight Steam Mop!
Size: Compact, Size: Compact
I’m really happy with the Schenley Steam Mop. It heats up in about 15 seconds and is ready to go almost instantly. It works well on my hardwood and tile floors, removing everyday dirt without needing any chemicals.
It’s lightweight, easy to maneuver, and I love that it stands on its own. The washable pads and adjustable steam modes are a nice bonus. The water tank is a bit small, but for regular cleaning it’s perfect.
Great value and very convenient for quick, effective cleaning!

Great versatile tool, not self-standing and missing a few accessories
Size: Standard
This is a great lightweight and versatile steam mop with good attachments. I would have given it five stars, but it is NOT self standing, does not auto-shut off, and does not have a built in cord wrap. You must manually buy the cord and then use their provided Velcro wrap to secure it in place. It also did not come with a storage bag for attachments, a cup to fill water tank, or a carpet glider.
It’s water tank lasts a long time during steaming and when combined with a floor cleaner, I apply directly to the floor, works wonders for our two large dog’s footprints on our 1000 sq. ft. of laminate flooring. One to two tanks of water clean the entire square footage.
After researching, I cannot find a better steam mop, with attachments that has all the features I want at $100. It also looks very sleek next to our Dyson. I would recommend.

The best!
Size: Standard, Size: Standard
This is definitely the best steam mop I have ever tried. It is easy to use and easy to assemble. I like the cord length. It covered my entire living room, kitchen and hallway. I just had to switch once! It comes with different attachments which you can use in your kitchen, and to clean windows etc. The mop pads are easy to clean and machine washable. It is definitely a must have if you want a clean, germ free home. Definitely recommended.

Absolutely Worth It!
Size: Standard
I've been using the Schenley Steam Mop for a few weeks now, and I'm genuinely impressed with how well it cleans. The steam heats up very quickly, and I love that I can clean my floors without using harsh chemicals. It easily removed dirt and sticky spots from my tile floors and left them looking fresh and sanitized. Very happy with the purchase!
