What the F19-02 Is
The F19-02 is an ultra-thin square smart window cleaning robot built for bezel-less glass and modern curtain walls. Its 216×216×69 mm square body carries a 72W brushless motor, 3,000–3,500 Pa of suction and a bidirectional 4-way ultrasonic spray, and it ships with a 12-month warranty and a full spare parts kit.
Square Anti-Scratch Design: Why It Matters on Frameless Glass
Most window robots use a round, mushroom-shaped chassis. On luxury frameless glass that shape is a liability: the wide round base drags across coated panes and around corners. The F19-02 uses a square bottom instead. It is designed to move over bezel-less glass and curtain wall glazing without the scratch damage that comes from a traditional mushroom head, which is the single most common complaint from property managers running robots on high-value facades.
The 69 mm body keeps the unit low on the pane so it can pass under narrow frames and around mullions where thicker units get blocked.
4-Way Ultrasonic Spray and 3,000–3,500 Pa Suction on Bezel-Less Glass
Suction is what holds the robot to the glass, and it is measured in pascals. The F19-02 runs at 3,000–3,500 Pa, with a 72W brushless motor driving the seal. Two spray holes per side deliver a bidirectional 4-way ultrasonic spray from a 60 ml on-board tank, so the microfibre pad works on wetted glass rather than dragging dry dust across the pane.
Combined with automatic edge detection, this is what allows the unit to keep a stable hold and full corner coverage on bezel-less glass, where there is no frame for a robot to bump against.
High-Rise Safety: Power-Off Suction Lock and Gyroscope Edge Detection
On upper floors the safety system is the product. The F19-02 pairs a gyroscope with mechanical collision sensors for edge detection, and adds power-off protection that maintains suction if power is cut, so the robot stays on the pane instead of dropping. The unit carries CE, RoHS and FCC certification.
Control, Cleaning Modes and Coverage
Three control methods are supported: a 2.4G remote, the Doodle App over Bluetooth, and voice control. Cleaning modes cover the N-shape, Z-shape and N+Z paths plus spot cleaning for individual marks.
Water tank capacity is 60 ml, noise stays at or below 63 dB, and the working speed is approximately 3.5 minutes per square metre. A built-in 650 mAh battery supports the unit between runs. Power input is AC 200–240V ~ 50/60Hz, 1.5A, with 24V 3.0A output.

Who Buys the F19-02 Wholesale
The F19-02 is supplied to smart home distributors, property management companies, hotel maintenance teams, glass engineering contractors and facade cleaning service providers. These buyers usually need a frameless-glass-safe unit that survives a real facade route, not a consumer gadget, and they buy in volume with spare parts and technical support behind it.

Frequently Asked Questions – F19-02 Window Cleaning Robot
What are the F19-02’s dimensions, and why does the 69 mm body matter?
The body is 216×216×69 mm. The thin profile keeps the unit low against the pane so it can pass through narrow frames and around mullions that block thicker window robots, and the square footprint is what allows it to work the corners of a pane.
Can the F19-02 be used on bezel-less or frameless glass?
Yes. It is designed for bezel-less glass and curtain wall glazing, and it relies on automatic edge detection with a gyroscope plus mechanical collision sensors rather than on a frame to stop against. The square anti-scratch bottom avoids the scratch marks a traditional mushroom-head chassis can leave on coated frameless glass.
What happens if the power is cut while the robot is on the glass?
Power-off protection maintains suction, so the unit stays attached to the pane instead of releasing. This is the protection that matters most on high-rise facade work, and the F19-02 carries CE, RoHS and FCC certification.
How much water does it hold, and how does the 4-way spray work?
The on-board tank holds 60 ml, and the bidirectional 4-way ultrasonic spray uses two holes per side, so the microfibre pad works on wetted glass instead of dragging dry dust across the pane.
How is it controlled, and what cleaning paths does it run?
Three control methods are available: a 2.4G remote, the Doodle App over Bluetooth, and voice control. Cleaning modes cover N-shape, Z-shape and N+Z paths, plus spot cleaning for individual marks.
What suction and noise level should I expect?
Suction is 3,000–3,500 Pa, driven by a 72W brushless motor, and the noise level is ≤63 dB. The working speed is approximately 3.5 minutes per square metre, and a built-in 650 mAh battery supports the unit between runs.
What is the minimum order, and can I test one unit first?
A 1 pc sample order is accepted so you can test the unit before committing to bulk. Bulk pricing and the MOQ for your target volume are quoted per order — send us the quantity and destination and we will confirm both.
What warranty, spare parts and support are included?
Every unit ships after 100% full QC inspection with a 12-month warranty, 24/7 remote technical support and a complete spare parts kit. OEM and ODM are supported, including custom logo, colour and packaging.
