Thanks for all your thoughts; it does look like it is possible. Before I place a pre-order, however, is there a way we can get someone from the product marketing or product design to confirm if the motorized brush head can be or cannot be directly attached to the Main unit?
I actually called the support phone number, but they thought it was not possible, but they were not 100% sure either.
Thanks much!
p.s., I am big fan of Wyze products and own quite a few, but one improvement I would like to suggest is that when they announce a new product with great promo pictures/videos and offer pre-orders, there should be an easy way to answer questions so we can determine if the product meets our needs.
