Hobot S7 Pro Now Cleans Angled Glass (20°–90°)

Brilliant news for UK homes with skylights, roof windows and sloped conservatory panels: the Hobot S7 Pro Robot Window Cleaner now supports angled glass from 20° through to 90° (vertical). That means safer cleaning, wider coverage and the same sparkling, streak-free finish you expect from Hobot.

Why the 20°–90° Range Matters

Many British homes feature sloped glass—think Velux-style roof windows, skylights, loft conversions, atriums, and conservatory roofs. Traditionally, these have been awkward (and risky) to clean. With the S7 Pro’s expanded operating angle, you can now automate those jobs while keeping your feet firmly on the ground. The S7 Pro combines powerful vacuum adhesion, intelligent traction control, and ultrasonic mist to maintain grip and glide—whether your window is steeply pitched or fully vertical.

More areas covered: Pitched roof lights, sloped conservatory panels, tall stairwell glazing, and glass balustrades.
Safer routine: Reduce ladders and risky reaches by letting the robot handle the angle.
Consistent results: Even distribution of fine mist (≈ 15 μm) for a smooth, streak-free finish.

How the S7 Pro Stays Secure on Angled Glass

The S7 Pro’s cleaning platform is engineered for stability on slopes. Active vacuum pressure keeps the unit attached to smooth glass, while its AI route planning manages traction and direction changes. A built-in UPS backup keeps the robot latched to the pane for several minutes if mains power is interrupted, and the included safety rope adds an extra layer of protection whenever you’re working at height.

In everyday use, you’ll notice the robot adopts steady, deliberate paths on pitched panes. That’s intentional: it balances coverage and grip to avoid slip-inducing sudden movements on sloped glass.

Best-Practice Setup for Sloped & Roof Windows

Anchor the safety rope above the pane: Choose a fixed point that’s higher than the glass you’re cleaning. Keep the rope slightly tensioned.
Start on a clean, dry pad: Fit fresh microfibre pads; for dusty skylights, run a quick dry pass before a wet pass.
Use distilled water or Hobot solution: Prevents mineral spots and supports even misting on angled panes.
Pick calm, dry weather outdoors: Wind and heavy humidity can disturb fine mist on sloped exterior glass.
Mind the edges & obstructions: Remove insect screens; ensure frames, latches and blinds won’t snag the robot.
Monitor the first clean: Watch a complete cycle on each new surface to confirm traction and coverage, then save your preferred mode in the app.

Is Your Glass Suitable?

The S7 Pro is designed for smooth, non-textured glass. It’s ideal for double-glazed units, skylights, roof windows, mirrors and large interior panes. Avoid use on heavily frosted, embossed or rough surfaces where vacuum adhesion is reduced. If in doubt, test on a small, safe area first with the rope anchored.

Who Benefits Most from the Angle Upgrade?

Conservatories & Orangeries: Keep sloped roof panels clear of pollen and grime without ladders.
Lofts & Attics: Clean pitched roof lights and skylights you’d normally struggle to reach.
Modern Stairwells: Maintain tall, angled glass without hiring specialist cleaners.
Architectural Features: Atriums and gallery spaces with dramatic sloped glazing.

Quick Start for Angled Glass (20°–90°)

Attach safety rope → plug in power → fit clean pads → fill tank (distilled water or Hobot solution).
Place the S7 Pro near the lower section of the pane; start via app or remote.
Select an auto route; for stubborn marks, add a second pass (spot or zig-zag).
After cleaning, wash pads, empty the tank and store the unit in a cool, dry place.

FAQs

What angles does the S7 Pro support?

The S7 Pro now supports angled glass from 20° to 90° (vertical), covering most sloped windows and skylights in UK homes.

Do I still need the safety rope on angled glass?

Yes. Always anchor the safety rope when working on vertical or sloped surfaces, particularly at height.

Can I use it on frosted or textured roof glass?

For best adhesion, use the S7 Pro on smooth, non-textured glass. Avoid heavy frosting or embossed textures.

What if there’s a power cut mid-clean?

The S7 Pro’s built-in UPS keeps it attached to the pane for several minutes, giving you time to remove it safely.
