It's difficult to estimate how much quicker it is to be honest , but it is quicker at removing sea gull poo snail trails , salt , etc on glass , on regular 4/8 weekly maintenance cleans , on really dirty first cleans it's a lot quicker, plastic cleans especially in the summer when the Algi , lichen is dry and crispy it's half the time to do the job , however I think if you were to pre spray it with virosol/tfr type of chemical it would soften it up as well . Temperature at the end of 100 of hose on a frosty morning I wouldn't describe it as extremely hot but it still makes a considerable difrance , well worth the cost in my opinion,
