It would make sense. The V11 & V15 dock film on YouTube are the same.
Maybe someone else can confirm. This is only their wall dock and not the freestanding pole version.
@Lauracat The “Floor Dok” for SOME Dyson V11 models is the same as for the Dyson V15 line.
Here’s how you can tell if it will be compatible:
If your Dyson V11 has a “click-in” style battery (NOT the “screw-in” battery) then it DOES use the same “Floor Dok” as the Dyson V15.
You can identify the “click-in” models because the model number on the battery will start with either “ SV15/SV17/SV28 “.
If your model stars with “SV14” your Floor Dok will NOT be compatible with the V15 line.
You can view the Floor Dok that works with both V11 “click-in” models and V15 models at this link: https://www.dyson.com/support/journey/tools/970778-01
