W5600X vs. Hobot: Which Window Cleaning Robot is Best for Frameless Glass?

When it comes to high-end window cleaning technology, the debate often boils down to the industry veterans like Hobot and the new generation of specialized tech like the Frewico W5600X. If you have a modern home with frameless glass balconies, shower doors, or glass railings, choosing the right robot is a matter of safety, not just cleanliness.

In this deep dive, we compare these two powerhouses to see which one truly masters the "edge."

1. Edge Detection: Pressure Sensors vs. Optical Sensors

Most Hobot models utilize optical sensors to detect the end of a window pane. While effective on standard windows, optical sensors can sometimes struggle with heavy glare or very thick, clear frameless edges.

The Frewico W5600X takes a more mechanical approach with High-Sensitivity Pressure Sensors. By monitoring the vacuum seal integrity in real-time, the W5600X can detect a "pressure leak" the millisecond it reaches an edge. For frameless glass, this physical data is often more reliable than light-based detection, ensuring the robot never oversteps the "cliff."

2. Suction Power: The 5600Pa Advantage

Suction is the lifeline of a window robot. While many Hobot models offer around 2400Pa to 3000Pa—which is perfectly adequate for standard use—the W5600X has been upgraded to 5600Pa.

• Why it matters for Frameless Glass: Without a frame to "catch" the robot, suction is your only safety net. The higher 5600Pa suction provides a massive safety buffer, allowing the robot to maintain a rock-solid grip even when navigating tricky corners or dealing with outside wind gusts.

3. Form Factor: Ultra-Slim Design

Modern architecture often leaves very little gap between windows and security bars or shutters.

• W5600X: Features an ultra-thin 72mm body, making it one of the slimmest square robots available.

• Hobot: Many of their popular models are slightly bulkier, which might limit their ability to clean behind balcony railings or narrow exterior gaps.

4. Spray Technology: Dual vs. Single

The W5600X features a Dual-Spray System, mimicking the human action of spraying on both sides of the movement path. This ensures the microfiber pads stay consistently damp, breaking down grime more effectively than single-nozzle systems found on entry-level professional robots.

The Verdict: Which Should You Choose?

• Choose Hobot if: You are looking for a long-standing brand with a wide range of accessories and a proven track record for standard framed windows.

• Choose Frewico W5600X if: You have frameless glass, live in a high-rise, or have tight spaces (security bars). The upgraded 5600Pa suction and pressure-sensing logic offer a modern, specialized solution for the most challenging architectural glass.
