Bests & Worsts Reviews from Amazon

I'm delighted and 100% satisfied with the quickie power scrubber. It's easy to operate it cleans beautifully and my bathrooms have never looked better. I would recommend this product with no reservations whatsoever. This is an addendum to my initial review. I'm still very, very satisfied; however, I have one question. "Where can I obtain/purchase extra brush heads? I would like to have one brush devoted entirely to cleaning toilets and nothing else. I've looked high and low to no avail. Can anyone advise me? Many thanks.
