C'mon HMAN - knock it on the head - you've now recycled this idea on here 2 or 4 times already, it's nothing new and is just something that complicates the issue
Holsters, taps, univalves, quick release fittings, handles with triggers etc..
all are already available and professionally made - each of the above have an advantage and disadvantage and more importantly suit different users needs ( no right or wrong )
but what your trying to peddle is tat ( sorry to say ) - I wonder if you have really ever done a days window cleaning because you fail to grasp what is needed
