For me remotes are too unreliable and don't save you enough water compared to the aquatap or aquadaptor basically time you have found your remote pressed the button and then allowed the pump to stop you could have cleaned another complete window. You also get lag with starting up because there is no physical stop like a tap so the pressure drops in the hose line, this takes several sections to build back up, this may not sound long but when the alternative is instant you difference could be an extra house clean per day
