Hobot Window Cleaner: I haven't cleaned my windows in years, how well will a robot window cleaner work?

The best use of any robot window cleaner is regular maintenance and preventing the build up of dirt etc. If you have not cleaned in many years, the robot and you may struggle to clean your windows extremely well.

It may mean a deep cleaning is required first, or external windows may need to be hosed and scrubbed down with dishwashing detergent to break up dirt deposits.

Of course this will depend on how dirty the are and what environment you live in. Altenatively, it may take a few passes with the robot window cleaner and several pads.
