FreedomWand Head Replacement use one for toileting and one for grooming.
The two biggest reasons people order the extra heads is for multi use and sanitary reasons…they keep one near the toilet to use strictly for toileting and one in the shower or on the counter top to use for other hygiene needs. The second reason to have an extra set in hand is for a second bathroom, work, second home, travel etc.
Also if you don’t need the extension you can just purchase a head and handle to keep your costs down.
Please note: This item is the FreedomWand head only - at least a handle is required to be operational.
