Randomly found my rapid drain flap floating in the water. Tried putting back with my fingers and didn’t last 5 min. Tried putting back using needle nose pliers to pull the notches through each hole and didn’t last one clean. I ordered a replacement and will install soon. BUT I have noticed the robot has next to nothing in the basket when I have run it without the flap attached as I await the part. Is it normal for it not to clean without the drain flap in? If so, I will have to buy a new machine if the replacement flap doesn’t fare any better. I was hoping I could just run the machine without the flap permanently but that doesn’t seem to be a good option. Anyone ever have the same issue with this small rubber drain flap, and if so have you had any luck with the robot cleaning even without it?
