If you want traditional style bonnets, I'd recommend these ones from John at CareCleanUK, at £16+VAT each:-http://www.carecleanuk.com/shop/products/17_FT_-Carpet-Bonnet.htmlThese Microfibres types are always on sale on eBay and are actually pretty good:-http://cgi.ebay.co.uk/17-Microfiber-Carpet-Shampooing-Washing-Bonnet-Pad-/130390025181?pt=UK_HomeGarden_CLV_Cleaning_CA&hash=item1e5bd9e3ddIf you want strong agitation, you can't go wrong with the XR Grey Pad from SolutionUK, but they are expensive at £35 each:-http://www.worldofclean.co.uk/index.php?productID=597Restormate also do a really good Heavy Duty (agitating) pad, at £30+VAT:-http://www.restormate.co.uk/epages/15094.sf/en_GB/?ObjectPath=/Shops/15094/Products/9526It may surprise some people to learn that one of the lowest cost standard pads on the market is still the Dry Fusion 'standard' pad (which I have 35 of!). But you cannot buy or order these unless you are a Dry Fusion licenced operator:-http://www.cleanerswarehouse.co.uk/cgi-bin/sh000197.pl?REFPAGE=http%3a%2f%2fwww%2ecleanerswarehouse%2eco%2euk%2fshopindex%2ephp%3ftid%3d10&WD=pad%20standard&PN=Dry_Fusion___Spare_Parts_%2ehtml%23a2_21D_2fSTA002#a2_21D_2fSTA002
