The cleaner robot category has moved from novelty to mainstream fast. In 2026, over 180,000 UK households own a robotic cleaner — and window cleaning robots are the fastest-growing segment.
What is a window cleaner robot?
A window cleaner robot — also called a cleaner robot, robotic window cleaner, or automatic window cleaner — is a motorised device that attaches to glass via suction and cleans automatically using:
- Negative-pressure suction to stay attached
- AI path planning to cover every centimetre
- Water-mist systems to loosen dirt
- Microfibre pads to lift and hold grime
Which surfaces can a window cleaning robot clean?
- ✓ Standard glass windows (single and double-glazed)
- ✓ Floor-to-ceiling glass panels
- ✓ Conservatory glass and skylights
- ✓ Bathroom tiles and mirrors
- ✓ Acrylic panels and splashbacks
- ✗ Textured, frosted, or leaded glass
Are window cleaning robots safe?
CleanBot R1's Triple-Safety System™ runs three independent failsafes simultaneously:
- Gravity-Lock™ (6,500 Pa) — primary grip
- Backup battery — maintains suction 30 min if power cuts
- Physical tether — 150 kg-rated final failsafe
In 2,400+ UK sales, zero falling incidents.
Can it clean the outside of my windows?
Most budget cleaner robots can only clean the pane they're placed on. CleanBot R1 is different: its dual water-mist system delivers precision cleaning to the external pane of standard double-glazed windows — from inside. No opening windows. No going outside. No risk.
