WA9C Pro Window Cleaning Robot, 4-Nozzle Dual Spray, 6 Cleaning Modes

Automating glass maintenance on tall or hard-to-reach panes is simple with a window cleaning robot built to handle the scrubbing for you. The Tosima WA9C Pro addresses the hassle of manual glass wiping by adhering directly to vertical surfaces while misting and wiping down panes systematically. For homeowners or apartment dwellers with large patio doors, high transoms, or expansive panes, it cuts down on the physical ladder work and reaching usually required to keep glass clear.

Moisture distribution is handled by a four-nozzle layout, placing two precision outlets on each side of the unit. The system actively clears air out of its internal fluid lines before misting, which helps prevent dry passes and creates an even spread of liquid across the surface. Handheld remote adjustments let you switch between regular misting and a larger fluid volume, so you can tailor the moisture level depending on how dirty the exterior glass is before the mop passes over it.

Staying firmly attached to smooth vertical glass relies on an internal suction system producing between 2600 and 3200 Pa of holding force. A built-in air pressure monitor works alongside a bottom drop sensor to track surface contact continuously, helping the cleaner navigate panes without losing grip. Navigation itself follows structured routines, including an N-shape path for vertical tall spans, a Z-shape route for broad horizontal panes, and direct manual steering from the remote when you need to focus on stubborn patches.

Because the unit runs on direct electrical power, working on elevated glass introduces practical safety requirements. The package includes an AC power cable and adapter that must remain connected during active cleaning, along with an anchored safety rope required for overhead tasks. If power cuts out unexpectedly, an internal backup battery holds the device to the window for up to 25 minutes while emitting light warnings and audio signals, giving you a reasonable window to safely detach it.

Verdict: The Tosima WA9C Pro is a capable choice for anyone managing high or wide residential windows who wants hands-off, automated cleaning with active dual-side spray. Those looking for a fully cordless cleaner without trailing cables or safety rope anchoring will need to consider manual tools instead.

A great fit if you:

• Have tall, broad, or awkward windows that require difficult ladder work to reach and wash by hand.
• Prefer an automated cleaning routine with directional patterns like Z-shape or N-shape paths for consistent coverage.
• Want the reassurance of emergency backup suction and alert sounds in the event of an accidental power interruption.
• Value having bundled maintenance spares, including extra cleaning pads, replacement spray nozzles, and an unclogging needle.

Consider something else if you:

• Need a cordless battery-operated glass tool that works without tethered power cords or anchored safety ropes.
• Only clean small, narrow windowpanes where setting up an automated suction machine offers little practical benefit.

Confirm on the listing:

• Check the length of the included AC power cord and adapter to make sure it reaches your nearest indoor electrical outlet.
• Verify whether your window frames provide an edge for the bottom drop sensor to detect boundaries.
• Review the anchor points near your high windows to ensure there is a sturdy object suitable for attaching the safety rope.
• Confirm the physical dimensions and weight of the machine to ensure it fits within your specific window frames.

How to compare your options: Focus on adsorption suction power, backup safety systems, and liquid application methods when weighing window cleaning machines. The Tosima WA9C Pro offers suction between 2600 and 3200 Pa, backed by a 25-minute emergency battery hold and a dual-sided four-nozzle misting system. Models with automated spray and dedicated path patterns generally require less hands-on oversight than basic dry-wiping pucks.

• Always secure the safety rope to an immovable, solid household structure before placing the unit onto high or exterior glass panes.
• Use the included water bottle to fill the internal fluid reservoir carefully to avoid spills around the electrical components.
• Switch between the Z-shape path for wide panoramic windows and the N-shape path for taller, vertical panes to maximize route efficiency.
• Swap out the four cleaning mops regularly between cleanings, washing dirty pads so they do not smear collected dust across fresh glass.
• Keep the spray lines clear by using the provided unclogging needle kit if you notice reduced misting from any of the four nozzles.

What happens if the power cord gets unplugged while it is working?
An internal backup battery immediately takes over to keep the robot adsorbed to the glass for up to 25 minutes. During this period, the machine emits visual light alerts and sound warnings so you can retrieve it safely.

What accessories come in the box?
The kit includes the cleaning robot, a remote control, four cleaning mops, an AC power cable with adapter, a precision water filling bottle, replacement nozzles, and an unclogging needle kit.

How does the robot know where to clean?
It features smart navigation modes including an N-shape path for vertical movements, a Z-shape path for horizontal coverage, and a manual mode controlled through the remote. Built-in pressure sensors and a bottom drop sensor help it monitor glass contact and edges.

Can I adjust the amount of water it sprays?
Yes, the included remote control allows you to toggle between a regular water spray volume and a larger spray volume depending on your cleaning needs.
