Maria Diaz/ZDNET Follow ZDNET: Add us as a preferred source on Google. From pet robots to way more robot mowers than the world needs, IFA features some of the coolest tech we'll see all year. Companies use the event to showcase new products and the latest innovations they're working on, and Anker delivered some exciting updates. Also: The coolest gadgets I've seen at IFA 2025 (including ones you can actually buy) Marswalker: A stair-climbing robot Maria Diaz/ZDNET Part of the appeal of events like IFA and CES is showcasing groundbreaking technology, even if it's still a prototype. This time, Anker has the Marswalker, a stair-climbing robot that can escort your robot vacuum up and down the stairs. The Marswalker isn't a robot vacuum in itself. Instead, it's a robot meant for the new Eufy Omni S2 robot vacuum and mop, though you can also use it with the S1 Omni. Anker is reportedly planning to make it compatible with the Eufy E25 and E28 robot vacuums and mops. Also: The latest robot vacuum innovation I've tested keeps my floors sparkling (and it comes with a spot cleaner) The purpose of the Marswalker is to solve a problem that many robot vacuum users have: having to carry their robot upstairs to clean a second story and then back downstairs to recharge when it's finished. The Marswalker has tracks to move along the stairs and can adapt its stride to the shape and texture of different types of stairs to move around. Anker plans for the Marswalker to go on sale next year, though pricing information isn't yet available. Other Anker products at IFA Maria Diaz/ZDNET Though the Marswalker is the flashiest product you'll see at Anker's IFA booth, it's not the only noteworthy one. From an AI voice recorder to the most powerful robot vacuum on the market, here are other products Anker announced during IFA 2025: Eufy Omni S2: This is the strongest robot vacuum and mop right now, with 30,000Pa of suction power. It is the successor to the S1 Omni, one of the best robot vacuums and mops. The Eufy Omni S2 has an improved mopping system, new optional aromas, and an extendable side arm. This robot will be available in late October. Soundcore Work: An AI-powered recorder can capture and transcribe audio files, and you can then ask the AI bot about what was discussed in the recording. Anker's Soundcore also announced new Sleep A30 earbuds with active noise cancelling (ANC) and a 4K portable projector called the Nebula X1 Pro. Also: Anker's coin-size AI recorder can transcribe and summarize your meetings - in one click EufyCam S4: Anker's Eufy brand combines three cameras to create the flagship EufyCam S4, a battery-powered security camera with a replaceable battery and solar panel support. The EufyCam S4 has a 4K camera and a dual-lens 2K pan-tilt-zoom (PTZ) camera to cover every angle and proximity. The S4 camera is available for presale for $300. Eufy also launched the Permanent Outdoor Lights S4 with a radar to detect motion so they can react accordingly. AI Core: This is powered by a Qualcomm 4-nanometer AI chip and works as an addition to a Eufy Security setup. The AI Core processes captured data from your cameras to make inferences on specific behaviors that a simple security camera system doesn't capture. For example, rather than simply detecting motion, the AI Core can identify situations as a whole to send you informative alerts, like when someone is trying to open your parked car. This device is still some months away, with price info to come. Anker Prime: Anker launched a 160-watt charger with a 1.3-inch display and three USB-C ports; a new 3-in-1 Prime Wireless Charging Station for Apple devices; and an Anker Prime Docking station with 14 interfaces to support 8K monitors, four USB-C ports, three USB-A ports, two HDMI ports, a DisplayPort, and an audio port. Buyers will also be able to purchase the Prime Powerbank 26K on September 25, while a 20K version is coming later.
