How Safe and Effective Is the Hobot S7 Pro on UK Windows?

One of the most common questions we get about the Hobot S7 Pro Robot Window Cleaner is: “Will it really stay on my windows—and clean them properly?” The answer is a confident yes. Here's how it works and why it’s completely safe for a variety of UK glass surfaces.

Powerful Suction That Won’t Let Go

The S7 Pro uses a high-performance vacuum motor that creates strong suction to keep the device attached to your window—even when cleaning vertically or overhead. Once started, it won’t slide, drop, or drift. And yes, it handles double glazing and thermopane windows without issue.

Built-In Safety System

Worried about power cuts? The S7 Pro includes an internal backup battery that provides 20 minutes of emergency suction in case the power fails. Plus, every unit comes with a secure tether rope for added peace of mind—especially useful for second-storey or loft windows.

Works on Framed and Frameless Windows

Thanks to its edge-detection sensors, the Hobot S7 Pro can clean frameless glass panels, mirrors, and shower doors without risk of falling. It intelligently detects the edges and adjusts its path to stay securely within the glass boundary.

Gentle Yet Effective Microfibre Cleaning

The cleaning pads are made from high-density microfibre material designed to lift dust, grime, and water spots without scratching your glass. It’s gentle enough for everyday cleaning but strong enough to remove buildup—even on neglected panes.

Compatible Surfaces in UK Homes

The S7 Pro works exceptionally well on:

• Double-glazed windows
• French doors and patio doors
• Mirrored wardrobes
• Glass balustrades
• Shower screens
• High or skylight windows

When Not to Use the S7 Pro

While it’s incredibly versatile, there are a few cases where the S7 Pro shouldn’t be used:

• Cracked or loose glass
• Textured or frosted windows (cleaning effectiveness may be reduced)
• Small panes below 30cm x 30cm

Real Results from UK Homes

Whether it's removing rain marks from conservatory glass or keeping bi-fold doors sparkling year-round, UK customers love how effective the S7 Pro is—without ladders, chemicals, or manual scrubbing.

Final Verdict

With smart sensors, powerful suction, and built-in safety features, the Hobot S7 Pro is perfectly suited for UK window types. It’s safe, efficient, and transforms one of the hardest cleaning tasks into a fully automated routine.
