We use this when come across windows have heavy build up of dirt clean rubbish out of tracks, pressure clean fly screens.
 And because it is battery powered also has it own water you can use it anywhere.

About 30minutes one battery before charging.

Don't know it is just to clean those windows that have not been cleaned for years.
Knock all the rubbish and $#!t off.
Be covenant where you can't get power or water tap.
It also takes two of those batteries as well so you can expect about hour run time.
