Smart Robotic Window Cleaner with Dual Ultrasonic Spray

Effortless Window Cleaning Starts Here

Large windows make a home feel brighter, more open, and more luxurious—but cleaning them can quickly become one of the most frustrating household chores.

Reaching tall windows, cleaning exterior glass, dealing with fingerprints and dust, and trying to avoid streaks can take time and energy. For floor-to-ceiling windows or large glass doors, the job can become even more inconvenient.

The Fmart W7 Smart Robotic Window Cleaner is designed to make compatible glass cleaning simpler. This fully automatic robot window cleaner combines intelligent movement, powerful vacuum suction, a brushless motor, and a dual ultrasonic water spray system to help maintain clear glass with less manual effort.

Attach the robot to a compatible glass surface, select a cleaning mode, and let the system follow its programmed cleaning route.

Smart Cleaning for Modern Homes

The W7 is more than a traditional electric window cleaner. It is a fully automatic glass cleaning robot designed for household use.

Its compact body measures just 245 × 245 × 85 mm, making it suitable for handling large compatible glass surfaces without requiring you to manually move a cleaning tool across every section.

With linear movement and N + zigzag cleaning routes, the robot follows a systematic path across the glass.

Whether you are maintaining large windows, glass doors, or other compatible smooth glass surfaces, the W7 offers a more automated approach to regular cleaning.

Why Choose the Fmart W7 Smart Window Cleaning Robot?

Dual Ultrasonic 2-Way Water Spray

One of the W7's standout features is its dual automatic water spray system.

The robot uses two ultrasonic spray nozzles and two removable water tanks. Each tank has a capacity of 25 ml, providing a total removable water capacity of 50 ml.

The ultrasonic spray system helps distribute water across the cleaning surface during operation, supporting the cleaning process while the robot moves across compatible glass.

Instead of manually spraying the window repeatedly, the automatic water spray system adds convenience to the cleaning routine.

Key benefits:

• Dual 2-way automatic water spray
• Ultrasonic spray nozzles
• Two removable 25 ml water tanks
• Total water capacity of 50 ml
• Reduced need for repeated manual spraying

Powerful 3800Pa Vacuum Suction

A window cleaning robot needs a secure attachment system to operate on vertical glass.

The W7 features a maximum suction power of 3800Pa, helping the robot maintain attachment to compatible glass surfaces during operation.

This powerful vacuum system works together with the robot's automated cleaning movement to create a practical solution for regular household glass maintenance.

The 3800Pa suction system is designed for compatible glass surfaces with a thickness of 3 mm or more.

Always make sure the glass surface is suitable before operation and follow the manufacturer's safety instructions.

---

Intelligent Gyroscope Navigation

The Fmart W7 uses gyroscope navigation to guide its movement across the glass.

Instead of random movement, the robot follows programmed cleaning patterns:

• Linear movement
• N-shaped route
• Zigzag route

These movement patterns help the automatic window cleaner cover the surface systematically.

The result is a more organized cleaning process, especially when maintaining larger windows and glass doors.

---

App-Controlled Convenience

The W7 can be controlled through a compatible app, giving you another way to manage the cleaning process.

The product supports operation in multiple languages:

• English
• German
• French
• Spanish
• Italian

App control adds flexibility to the smart home cleaning experience and makes the W7 a practical addition to a modern household.

---

Efficient 72W Brushless Motor

At the heart of the W7 is a 72W brushless motor.

Brushless motor technology is designed to provide efficient operation for the robot's automated cleaning system.

Combined with the 3800Pa maximum suction power, the motor supports the robot's ability to remain attached to compatible vertical glass while moving through its cleaning routes.

---

Designed for Large Compatible Glass Surfaces

The Fmart W7 can operate on windows with a minimum workable size of:

40 × 40 cm

It is designed for compatible glass with a thickness of:

3 mm or greater

This makes the smart robotic window cleaner suitable for many household applications, including compatible:

• Large windows
• Glass doors
• Balcony glass
• Floor-to-ceiling windows
• Panoramic glass panels
• Smooth household glass surfaces

Before using the product, always check that the specific surface meets the manufacturer's requirements.

A Smarter Alternative to Manual Window Cleaning

Traditional window cleaning usually involves multiple steps.

You may need to:

1. Prepare water and cleaning solution.
2. Spray the glass manually.
3. Reach high areas with a cloth or squeegee.
4. Repeat the process across the entire surface.
5. Go back over the glass to remove visible streaks.

The Smart Robotic Window Cleaner helps automate part of that routine.

With automatic movement and dual ultrasonic water spray, the W7 is designed to reduce the amount of repetitive manual work involved in maintaining compatible glass surfaces.

You still remain responsible for proper setup, surface suitability, supervision, and maintenance—but the robot can help make routine cleaning more convenient.

---

Automatic Cleaning Modes

Different windows and cleaning situations may require different movement patterns.

The W7 offers automated cleaning routes, including:

Linear Movement

A structured movement pattern designed for systematic cleaning across the glass.

N + Zigzag Route

The robot follows an N-shaped and zigzag cleaning path to move across compatible surfaces.

These automatic movement modes help the robot perform its cleaning cycle without requiring you to manually guide a cleaning cloth across the entire window.

---

Compact, Lightweight Design

Despite its automated features, the W7 remains relatively compact.

Product Dimensions

245 × 245 × 85 mm

Net Weight

1.25 kg

The compact form factor makes the robot easier to handle when positioning it on a compatible glass surface.

The product's body is constructed from ABS material, a widely used engineering plastic chosen for its balance of durability and relatively low weight.

---

Long Operating Capability

The W7 is listed with:

• 750mAh battery capacity
• Maximum runtime: 121–150 minutes

The battery specification supports the product's operating system as listed by the supplier.

How the Dual Water Spray System Works

The W7 includes two removable water tanks.

Each tank holds:

25 ml

Together, they provide:

50 ml total removable water capacity

The dual ultrasonic spray nozzles automatically distribute water during compatible cleaning operations.

This design helps reduce the need to stop and manually spray the glass as frequently.

For best results, use the liquid or cleaning method recommended by the manufacturer and avoid adding unsuitable substances that could damage the spray system.

The Fmart W7 can be particularly useful for people who have:

• Large glass windows
• Modern apartments
• Balcony doors
• Wide glass panels
• Floor-to-ceiling windows
• Difficult-to-reach compatible household glass

Instead of spending long periods manually moving a cleaning tool across every section, you can use an automated cleaning device to assist with the task.
