I have used Spartan products at my shop and home for many years.second to none.I recently came in for carpet cleaner.the clerk asked me if it was a shampooer or extractor.I replied it was a rental and as far as I knew it was a shampooer. He sold me a gallon of plus 5 cleaner.As I was at the counter paying I read on the label high suds.I asked him if he had anything else .he then asked me if my machine has brushes when I told him it did he assured me it would work fine.I tried using it in my rental and...suds overflowing.although my machine does have a beater brush turns out it is a extractor.I returned product {all but 4 oz.}.clerk then sold me correct product. He refused to give me any credit for returned product.he responded several times that i told him it was a shampooer .Would it have been to much to offer a discount, store credit or even to say sorry?Less than 20 dollars not a big deal.
