We have a Dyson DC 29 The included switchable floor nozzle has however regularly festgesaugt our hard floors (tiles, cork, PVC and lacquered floor) due to the high suction power at the nozzle, if you wanted to suck without "brush border" flat on the floor. With high-ranking brush at the edge, you have partially shuffled "debris" in front of him. The almost exclusively positive reviews of Flat Out floor brush in the reviews, I can now after 4 weeks test also totally agree. The flat floor nozzle can be without the hassle of suction and effortlessly pull / push on the bottom and comes still very flat furniture etc. underneath. The suction power is in my opinion a little less than that of the switchable floor nozzle, but just fine. Also, you can suck on the air ducts with open sliders on the sides side the dirt. The Flat Out floor nozzle fits without an adapter piece perfectly on the telescopic tube of the DC 29. The nozzle as opposed to switchable floor nozzle no "hook" to attach the device to the sucker, because you'll not easily comes under the furniture. This is in my eyes is not really a disadvantage. A little annoying is that you have to open from time to time, the lateral slide again (if you want to have these open), as these probably be adjusted by fiddling under the furniture manchesmal itself. Ultimately, I can only recommend all the floor nozzle warmly that are annoyed by the hard eyes / suction on smooth floors.
