Is it worth it?
If you’ve ever wrestled with ladders, long poles and streaky panes to keep your high-rise windows spotless, the eTRY X11 arrives like a breath of fresh air. Designed for homeowners and business owners with floor-to-ceiling glass or tall mirrors, it tackles the frustration of dangerous climbs and uneven spray coverage. With AI-driven path planning, ultrasonic dual sprayers and a turbo 3500 Pa suction motor, it promises streak-free glass without a second thought. But does it live up to its high-tech promise? Let’s dive in and see whether it can truly transform your window-cleaning routine.
After spending weeks running the X11 across sliding doors, storefront glass and budget-friendly models side by side, here’s my verdict: if you crave hands-off cleaning on smooth, frame-free surfaces, this robot is a game changer. But if your home is dotted with complex window frames or outdoor ledges, you may find yourself guiding it more than expected. I loved its safety features and coverage, yet I stayed curious about its water spray reach and pad longevity. Read on to discover who will benefit most—and who might want to wait for the next firmware update.

Key Features
Turbo Suction System
The X11’s core is a 3500 Pa turbo motor imported from precision-engineering suppliers. It generates a vacuum strong enough to pull stubborn smudges into the microfiber pads, eliminating the need for aggressive scrubbing.
This level of suction matters because it maintains constant contact between the pad and the glass, so debris is drawn away rather than pushed around.
For instance, after my dog left nose prints on a living-room door, one pass with the turbo system erased every trace without dust clouds or pad slippage.
Ultrasonic Dual Spray
Built-in ultrasonic nozzles atomize water into a fine mist, ensuring even distribution across large surfaces. The dual-head design covers up to 320 sq ft on a single 70 ml fill, so you refill less often when tackling full-height windows.
A fine mist minimizes runoff and streaking because droplets settle gently, saturating the glass just enough for the microfiber pads to work.
During a balcony window test, I saw no drips onto my deck—a dramatic improvement over handheld sprayers that oversaturate and drip.
Safety Guardian System
Combining a gyroscope-based edge detector, UL-certified UPS battery backup and a 13-foot ASTM-tested safety tether, the X11 prioritizes fail-safe operation. If power cuts out, the UPS keeps suction active for up to 20 minutes—more than twice the industry average—so the robot won’t drop.
The gyroscope senses window borders and redirects the device before it hits a frame, while the tether is rated to hold 550 lbs of force.
I triggered a simulated power failure during a cleaning cycle, and the X11 hovered securely, allowing me to retrieve it without panic.
AI Smart Navigation 3.0
With onboard AI path planning, the X11 maps each pane to determine optimal Z-pattern, edge-focus or spiral cleaning. It adapts in real time if it encounters obstacles like window handles or grills.
This intelligence maximizes coverage and reduces redundant passes, cutting cleaning time versus random or strictly linear routes.
In practice, the algorithm shaved two minutes off my large patio-door clean, compared to my old robot’s default zigzag routine.
One-Touch Operation
The included remote control offers starter presets—Z-pattern, edge boost or continuous spiral—so newcomers can pick a mode instantly. Advanced users can manually direct the robot for spot treatments.
This simplicity matters when you’re balancing kids, pets and chores: no steep learning curve, just point, press and watch.
After showing my grandmother how to use it, she confidently cleaned her bathroom mirror solo within minutes, which was a pleasant surprise.
Firsthand Experience
Unboxing the X11 felt like setting up a mini spaceship. The packaging included five pairs of microfiber pads, a compact remote and a reassuring 13-foot safety tether. The first attach to my living room picture window was almost meditative as the wheeled pads snapped on and the machine hummed to life with a 0.3 s emergency response guarantee.
By day three, I tested it on a second-floor mirror. Despite gentle fan breeze, the AI navigation plotted a near-perfect Z-pattern route, leaving only a faint film at the very edges—easily wiped away by hand. I noticed the dual ultrasonic sprayer needed a refill roughly every 300 sq ft, matching the advertised 320 sq ft per tank.
On my storefront glass, I appreciated the 20 minutes of UPS backup when the outlet tripped. Unlike my old cordless cleaner that died in five minutes, the X11 clung on and descended safely. The gyroscope edge-detection kept it from wandering off the glass border, though it occasionally misread roller-shade housings.
After a week of daily runs, the reusable pads showed wear around the stitched corners, but five extras kept me going without interruption. I found the reservoir refill process fiddly—it required a small Phillips screwdriver to remove a wheel—and I missed a quick-flip cap design.
Most evenings, I’d start the X11 from the couch with one-touch remote control. Watching it glide up and down glass panels became oddly soothing, like a tiny, precise painter. Even on a rainy afternoon, window interiors glowed as if buffed by hand.
Pros and Cons
Customer Reviews
Overall, users praise the X11’s strong suction, AI-driven routes and hands-off approach to high or large windows, noting significant time savings. Critiques focus on the water mist coverage, pad durability on very dirty panes and occasional misreads around shaded housings. With 31 reviews averaging 4.1 stars, opinions range from “must-have” to “needs engineering tweaks,” reflecting an early product finding its stride.
For the big windows it's ideal to use. Makes cleaning simple and easy and not a chore
Easy to use with simple controls, but you must finish edges by hand and it can get stuck on window hoods
Attaches firmly and works well on large balcony windows
Cool concept but requires constant supervision and struggles with roller shades
Needs better reservoir access and autonomous return when water empties.
Comparison
Compared to budget window robots under $100, the X11’s advanced AI routing and triple-layer motor deliver noticeably more consistent streak-free results, though the entry-level models often sport user-friendly fill ports.
Flagship competitors like the Hobot Legee 688 reach slightly higher spray volumes and offer app integration, but carry a 30–40% price premium—making the X11 a solid midrange pick for those who don’t need smartphone controls.
Against the Ecovacs Winbot series, eTRY matches edge-detection accuracy and exceeds backup runtime without adding bulk. Winbot’s sleeker design may appeal to style-focused buyers, but the X11 wins on raw cleaning power and safety margins.
Frequently Asked Questions
- Can I use the X11 outdoors?
- Yes, but wind can disperse the fine ultrasonic mist—consider a wind shield or manual spray
- How often do I need to replace the pads?
- The reusable microfiber pads last 15–20 full-window cycles before noticeable wear—extra sets are included
- Will it climb framed windows?
- It handles most frames, but very recessed or protruding trim may confuse the edge sensors
- What power outlet do I need?
- Standard 110 V AC—if you’re outside the US, a step-down transformer may be required.
Conclusion
The eTRY X11 delivers a compelling blend of turbo suction, AI navigation and emergency safety that redefines hands-free window cleaning. Its fine-mist system and reusable pads erase the need for dangerous ladders and ladderside scrubbing on most smooth glass surfaces.
However, if your home features ornate frames, roller-shade housings or gusty outdoor conditions, you’ll still need to supervise its path and manually finish edges now and then. At around $150 (down from $190), it offers high-tier cleaning performance without flagship pricing—just be prepared for tool-assisted reservoir fills and pad maintenance. For anyone seeking a safer, faster solution for large interior and exterior windows, the X11 is worth exploring and monitoring for firmware improvements.
