HUTT Window Cleaning Robot, Window Cleaner Robot, World-First Round-Square

$333.99
in stock
Amazon.com
  • World’s First Certified Round–Square Dual-Stage Cleaning | n-tv Test Winner: HUTT 10 Premium combines a 70 RPM round pad for wet lifting with a precision square pad for dry wiping and polishing. In an independent three-model comparison conducted by leading German media outlet n-tv, HUTT was named the Test Winner for its outstanding overall cleaning performance. Its dual-pad system performed especially well in removing pollen, fingerprints, and everyday dirt while reducing streaks and cleaning close to edges—combining the strengths of round and square designs for better edge reach, corner coverage, frame-line cleaning, and a clearer finish.
  • 6500Pa Strong Suction + 55N Constant Pressur: Powered by a high-performance brushless motor, this Robot Window Cleaner delivers up to 6500Pa suction for stable vertical adhesion. A patented 3D suspension base maintains constant 55N (12.3 lbs) of pressure, simulating manual scrubbing strength for enhanced stain removal without damaging glass.
  • Dual Ultrasonic Spray + 80ml Tank Coverage: Dual-direction ultrasonic mist delivers even surface hydration, while the 80ml visible tank supports up to 60㎡ (646 sq ft) per refill. The synchronized wet-lift and dry-polish process helps achieve a clearer, streak-reduced finish. For best spray performance, we recommend using purified water with minimal impurities to help reduce mineral buildup and prevent nozzle clogging (No cleaning liquid included).

If the robot drifts off path, has difficulty turning, or slips near window edges, it is usually caused by dust or moisture on the drive tracks, or overly wet cleaning pads reducing traction. Keep the tracks clean and dry, use the square pads dry, and thoroughly wring out the round pads before use.
  • 30-Min Power-Off Protection + 220kg Safety Rope: Built with multi-layer protection for elevated cleaning. Includes a mountaineering-grade safety rope rated to 220kg and a built-in UPS battery that maintains adhesion for up to 30 minutes during power interruption—helping reduce fall risk.

  • Multiple Cleaning Modes: Support targeted deep cleaning, ideal for windows, mirrors, shower doors and sliding doors. Works perfectly on tiny glass surfaces starting from 30×30cm. Comes with remote control, safety rope, spray bottle, 6 nozzles and 3 pairs of cleaning pads. Includes a wide-voltage power adapter (110–240V AC) for convenient use in the US and other regions.

How to Choose Window Cleaning Robots

Suction Power

Look for a window cleaning robot with at least 6000Pa suction power. This ensures it can handle tough dirt and grime. Higher suction means a more thorough clean, especially for outdoor windows.

Cleaning Modes

Consider models with multiple cleaning modes. These modes can adapt to different window types and conditions. Having options gives you flexibility based on how dirty your windows are.

Safety Systems

Safety features are important for window cleaning robots. Look for models with safety ropes or backup batteries. These features ensure the robot stays attached and functions correctly during cleaning.

Size and Weight

Compact and lightweight robots are easier to store and handle. If you live in a small apartment, choose a model that is easy to move. Smaller robots can fit in tighter spaces for effective cleaning.

Water Tank Capacity

Check the water tank capacity of the robot. A larger tank means less frequent refilling. This is important for longer cleaning sessions and larger windows.

What to look for

Cleaning Efficiency

Battery Life

Battery life is important for window cleaning robots. Models should offer at least 60-110 minutes of cleaning time on a full charge. This is important for larger windows. Longer battery life means you can clean more windows without needing to recharge.

The best robots use advanced navigation technology. This helps them map out cleaning areas and avoid obstacles. Look for options with smart navigation, as they clean more efficiently without missing spots.

User-Friendly Controls

User-friendly controls simplify operation. Many robots come with remote controls or smartphone apps. Look for features like scheduling and one-touch cleaning, as these make your cleaning experience easier.

Maintenance Requirements

Check the maintenance needs of your chosen robot. Some models require more frequent cleaning of pads or water refills. Choose one that fits your lifestyle and how often you plan to clean your windows.
