Most UK homeowners assume that a professional window cleaner is the easiest option. They are right — until they do the maths. This guide breaks down the honest, real cost comparison between a robot window cleaner and hiring a professional, for a typical UK home in 2026.
The Real Cost of a Professional Window Cleaner in the UK
- Average cost per visit (3-bed semi): £15 to £25
- Typical frequency: every 4 to 6 weeks
- Annual cost: £180 to £325
- Over 5 years: £900 to £1,600
That figure rises every year as prices increase. It also does not factor in the inconvenience of scheduling, waiting in, and reduced availability during bad weather.
The Real Cost of the ClearBot R1 Robot Window Cleaner
- One-time purchase price: £173 (was £229.99 — saving £57)
- UK delivery: Free
- Annual electricity cost: approximately £3 to £5
- Replacement microfibre pads (every 6 to 12 months): £8 to £15
- Total over 5 years: approximately £215 to £250
The Break-Even Point
At £20 per visit, the ClearBot R1 breaks even after just 8 to 9 visits. For bi-weekly cleaning that is under 4 months. For monthly cleaning, under 9 months. Every clean after that is effectively free.
