I'm sorry but it's not the same thing at all,I have a Gardiner brush with fan jets,the rinse isn't as good and doesn't cover the same amount of glass.As for scrubbing twice,with a normal brush it may be the case but not with the Constructor brush,the configuration of the bristles make scrubbing and rinsing possible at the same time..........on regular cleans,first cleans it's a different story 😊
