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

Tall panes, sliding panels, and glass shower enclosures quickly gather grime, yet reaching every corner by hand is often tiring or awkward. The HUTT window cleaning robot automates vertical glass care by combining motorized scrubbing with systematic navigation. Engineered for homeowners with extensive exterior windows, high interior glass, or large mirrored surfaces, it provides hands-free cleaning that handles everyday buildup like dust, fingerprints, and pollen without requiring step stools.

Its primary mechanical distinction is a dual-stage pad layout. A 70 RPM round pad handles the initial wet lifting, while a trailing square pad dry-wipes and buffs behind it. Because square designs naturally match straight window corners, this layout allows the machine to follow frame lines more closely than round-only units. Glass surfaces receive hydration through dual-direction ultrasonic sprayers fed by an 80ml visible water reservoir, which holds enough liquid to mist up to 60 square meters (646 square feet) per fill.

Adhesion and scrubbing strength rely on a brushless motor producing up to 6500Pa suction. Beneath the body, a 3D suspension base maintains a constant 55N (12.3 lbs) of downward pressure against the pane, duplicating the mechanical force of a firm manual wipe. Navigation is directed by the NAVI 7.0 system and an array of 14 sensors that monitor edge boundaries and air pressure. The robot plans its routes automatically and can clean compact window panes starting at 30 by 30 centimeters.

Safety features protect the unit during elevated work. A built-in uninterruptible power supply (UPS) maintains vertical suction for up to 30 minutes if wall power cuts out unexpectedly, and a safety rope rated for 220kg anchors the unit to an interior fixture. At 1.3kg and operating at 65dB, the chassis remains manageable to lift and runs quietly during household chores.

Operating this robot requires attention to pad moisture and traction. The drive tracks rely on grip, so if the square wiping pad becomes wet or if the round pad is not thoroughly wrung out, the unit can slip or drift along frame edges. It also ships without cleaning solution, and the manufacturer recommends using purified water to prevent mineral deposits in the spray nozzles.

Verdict: The HUTT window cleaning robot is an excellent investment for homeowners managing tall windows, shower stalls, and sliding glass doors who want automated maintenance with tight edge reach. Buyers looking for an entirely waterless or unmonitored setup that requires zero pad prep may prefer a standard manual squeegee or basic commercial service.

A great fit if you:

• Have large sliding doors, mirrors, or hard-to-reach exterior windows where manual wiping is physically demanding.
• Need a window cleaner that reaches close to straight frames and corners using a dedicated square polishing pad.
• Want multi-surface flexibility for glass panels as small as 30 by 30 centimeters, including interior shower enclosures.
• Value built-in power backup that holds the unit against the glass for 30 minutes during sudden outages.

Consider something else if you:

• Prefer a completely cordless battery-powered cleaner that does not require an electrical power cord during operation.
• Want a machine that includes ready-mixed commercial glass detergent directly in the shipping box.

Confirm on the listing:

• Check the dimensions of your smallest glass panes to verify they meet the minimum 30 by 30 centimeter requirement.
• Confirm the location of electrical outlets near your target windows to ensure the power cord reaches comfortably.
• Check whether your windows have clear outer frames or borders for the 14 detection sensors to read properly.
• Confirm that you have a secure interior anchor point available to tie off the 220kg safety rope during elevated runs.

How to compare your options: Focus on suction strength, corner coverage, and safety backups when evaluating automated glass cleaners. While round cleaning pads excel at spinning away stains, hybrid models that incorporate square wiping edges provide cleaner results along borders. Look for high vertical suction (such as 6500Pa) and power-loss battery retention if you plan to clean high exterior windows.

• Always secure the 220kg mountaineering-grade safety rope to a solid indoor anchor before placing the robot on exterior or elevated glass.
• Fill the 80ml water reservoir with purified water rather than tap water to prevent mineral scale from clogging the ultrasonic nozzles.
• Wring out the rotating round cleaning pad thoroughly before installation so excess liquid does not transfer onto the tracks.
• Keep the rear square buffing pad completely dry to prevent traction slippage and ensure a clear, streak-reduced polish.
• Wipe down the rubber drive tracks periodically to clear away dust or trapped moisture that might cause the unit to drift or struggle during turns.

What comes inside the box?
The package includes the window cleaning robot, a remote control, a safety rope, a spray bottle, six replacement nozzles, three pairs of cleaning pads, and a wide-voltage 110-240V power adapter.

Does this unit come with cleaning solution?
No, cleaning liquid is not included in the package. The manufacturer recommends using purified water with minimal impurities in the 80ml tank to avoid clogging the ultrasonic spray nozzles.

What is the smallest glass size it can clean?
The robot works on glass surfaces measuring at least 30 by 30 centimeters, making it suitable for compact windows, mirrors, shower glass, and sliding doors.

What happens if the electrical power cuts out while it is working?
The built-in UPS battery maintains vertical suction for up to 30 minutes after power loss, and the included 220kg-rated safety rope serves as a backup physical tether.

Why is the robot slipping or having trouble turning along edges?
Slipping is typically caused by moisture or dust on the drive tracks, or by an overly wet square pad. Keep the square pad dry, keep the drive tracks clean, and wring out the round pads thoroughly before use.
