Full marks - no question!

Video at Amazon.com Send a totally satisfactory suction - what comes before the turbo brush, lost.
By the width of the turbo brush you can thus make a little "face" on the carpet, which is rather cumbersome with the otherwise customary in cordless vacuums narrow suction openings.
If women feel the heavy hand Auger as something I can indeed understand, but since I do not mind the weight, I prefer it, no points off.
The same applies to the fact that I had unfortunately to send back the first ordered Gator M137, because the thing could not be on again after a first (and absolutely convincing) test application. The reviews here on Amazon suggest that this is not a ****** S device, but I just had the misfortune to get a Monday device. Can occur even once. Because that thing from Amazon itself will be sent also the replacement sucker was almost as fast as I could to the old pack again and send it back.
A special plus for me and maybe a criterion for other clients who have pets: The device is indeed to my mind not exactly quiet, but clearly sonorous than my other battery operated vacuum cleaner, of the various wired "big" that it in our household there, too, of course. When I start the M137 in the bird room, rest of my parakeets not what they always do otherwise, when a vacuum cleaner is turned on.
A beautiful, powerful device that can only be compared with devices that cost well over 100, -EUR.
Buy recommendation!
