That not only means your application rates will be off, but that you now have a difficult mess to deal with inside your tank.
I'll assume that most daily sprayers are running 200-500 gallon tanks and sloshing isn't going to keep them mixed.
I do like electric on 10-35 gallons tanks, especially for roundup which will destroy most pumps. I use an rv water pump for that and when it's dead, clean and toss it.
