The return window is closed but stay away from the brand elefly ,fly to another brand I give this one star and this intermediate would go in and out and blue light would blink but to switch it to max suction would be no chance .
Pros
Vacuums & Floor Care
Cons
Risk of damage: Since ELEFLY's battery replacement isn't an official Dyson part, there's always a risk that using it might damage other parts of your vacuum cleaner
