Anker's Eufy brand didn't stop at the NVR Security System E50 and Fall Detection Sensor at IFA Berlin 2026: it also revealed four more products spanning entry security, window monitoring, and outdoor robotics. The Video Doorbell S4 is a wired, 9MP doorbell camera with a 180-degree field of view; the Window Camera E10 is a small 2.5K indoor-to-window camera built for color night vision; the Robot Vacuum Omni E35 adds sterilisation and dust-mite removal to its cleaning routine; and the Robot Lawn Mower S2 Max is a fully autonomous mower that can handle slopes most robot mowers can't. Pricing spans $70 to $1,300, and availability ranges from this month to mid-2027, so treat the details below as launch-market specs rather than a hands-on review of shipping UK stock.
What does the Eufy Video Doorbell S4 offer over Eufy's existing doorbells?
The S4 is a wired video doorbell shooting at 9MP resolution with a 180-degree field of view, a noticeably wider and sharper spec sheet than Eufy's earlier battery doorbells covered in our Eufy camera guide. The headline feature is OmniTrack, an auto-framing system that keeps a visitor centred in the frame as they move across the porch rather than leaving them clipped at the edge of a fisheye lens, according to Engadget's IFA 2026 coverage (Engadget). Eufy is pricing the S4 at $299, with availability starting in September 2026 across multiple markets. As with the E50 NVR system covered in our Eufy E50 and Fall Detection Sensor article, UK pricing and a firm UK on-sale date haven't been confirmed yet, so the $299 figure should be read as a US launch price for now.
What is the Eufy Window Camera E10 for?
The Window Camera E10 is a small, low-cost camera designed to mount against glass and shoot outward, aimed at buyers who want a discreet way to monitor a driveway or side passage without drilling into brickwork. It records at 2.5K resolution and uses an f/1.0 aperture lens for colour night vision, which should mean less grainy, greyscale-only footage after dark compared with cheaper cameras that fall back to black-and-white infrared. A 25-degree adjustable tilt lets the camera be angled to cut down on reflections and blind spots caused by shooting through glass at an angle (Engadget). At $70, it's priced well below Eufy's mainstream outdoor cameras, positioning it as a supplementary camera rather than a primary security device. Eufy hasn't given a firm release date beyond "later in 2026."
Does the Robot Vacuum Omni E35 do anything beyond cleaning?
Yes — the Omni E35's pitch leans heavily on hygiene rather than raw suction. Eufy says it can sterilise floors and remove dust mites as part of its cleaning cycle, using multi-cyclone filtration to capture fine particles, paired with a self-cleaning roller mop so the mopping pad doesn't need to be manually rinsed after each run. Eufy has had the device TÜV and AAFA certified — the Asthma & Allergy Friendly mark specifically — to back up the allergen-reduction claims rather than leaving them as unverified marketing copy (Engadget). Pricing is set at an early-bird $1,000, rising to a standard $1,300 once the introductory window closes, with EU/UK availability reported around the IFA show dates in early September 2026. That puts it well above Eufy's budget vacuum range and squarely against premium rivals — worth comparing against the wider field in our robot vacuum comparison coverage before buying at launch pricing.
How steep a garden can the Robot Lawn Mower S2 Max actually handle?
The S2 Max is pitched as a fully autonomous mower — mapping, mowing and returning to dock without a buried boundary wire, in the same vein as Roborock's RockNeo Q2 covered in our Roborock IFA 2026 lineup piece. Eufy rates it for lawns up to roughly 3.7 acres, considerably larger than most robot mowers aimed at UK gardens, and gives it all-wheel drive specifically to keep traction on slopes of up to 38 degrees — steep enough to cover terraced or sloped gardens that would stall a standard two-wheel-drive mower (Engadget). The catch is timing: Eufy isn't planning a European launch until May 2027, so this is a hardware reveal well ahead of any UK buying decision rather than a product you can order this year.
Do any of these four new Eufy devices work with Home Assistant?
Eufy hasn't confirmed Home Assistant or Matter support for any of the four devices announced alongside the E50 and Fall Detection Sensor at IFA 2026. Eufy's existing doorbells and cameras have a patchy integration history — some models work through community-maintained Home Assistant integrations rather than an official one — so buyers who specifically want local HA control should wait for Eufy to confirm compatibility rather than assume it from past product lines. IFA 2026 was a busy show for security-adjacent local-control announcements more broadly, including SONOFF's OpenEdge platform and Anker's own MindBase hub, both unveiled at the same event. We'll update this article once Eufy publishes integration details for the S4, E10, Omni E35 or S2 Max.
