Only 20 minutes use of the battery according to the spec. Some thoughts occur to me. Wouldn't people think why do I need a window cleaner if you turn up with one of those? Does it need detailing? They look cumbersome and awkward in tight spaces.
Exactly, nothing to stop a customer buying one especially after he has been shown how to use it by his window cleaner.
I hate cleaning interior windows so I wish this were true.
I used to cringe when a customer would ask me to clean the insides.
Since getting a karcher not a problem.
You do need to detail the edges but one microfiber will do a large house with conservatory.
Not something I would buy for exterior cleans no point.
