Another carpet damaged by a Dyson vacuum.


Thought I would share this again as it continues to be a problem. The customer's field carpet areas were all fuzzed out on the extreme 1/4" to 1/2" of the yarn tufts. Carpet had not been professionally cleaned yet. Customer vacuums every other day. Very well maintained home. Dyson vacuum. No pile height adjustment capability and very stiff brushes. Outside baseboard perimeters where the vacuum can not reach look new. So sad! Consumers are not being told the full story by carpet manufacturers or retailers. Even consumer magazines overly judge the soil removal properties of vacuums but not the damage that can be caused by vacuums or their misuse. Need to get the overall story out to the public.

Re: Another carpet damaged by a Dyson vacuum.


I keep hearing these reports of Dyson damage but haven't noticed any problems in homes that own Dyson's that I've done work.

Are you sure it isn't bad carpet?

Re: Another carpet damaged by a Dyson vacuum.


If you use a Dyson Vacuum cleaner on a Carpet made by Unique Carpets LTD. you will void the warranty. It says so right on the flier that comes in the roll of carpet. Nonetheless, I think that the carpet in the picture is defective ....

Re: Another carpet damaged by a Dyson vacuum.


Always a possibility it is the manufacturer's fault - easy report to write. However, there is no field test that I as an inspector can do to determine if the heat set is incorrect. Testing can only be done at the nmanufacturer's lab or an independent testing lab. Heat set problems would ususally show up before finishing of the carpet occurred. This carpet was tested independently and found to have no heat set problems. Not manufacturing. Vacuum abuse.

Re: Another carpet damaged by a Dyson vacuum.


I have also run into this problem several times. Just for my own curiousity do you know the specs for tuft length on that carpet Curt?

Ken, Have a few tufts saved in a zip-lock. Measured 1" from latex bud to tips.

no wonder the vac shredded it even a hoover/eureka etc. would have done that just taken a little longer.

Re: Another carpet damaged by a Dyson vacuum.


The last couple of inspections that I have done for this type of complaint were with fibers that were all approximately 1 inch long. None of them used a Dyson, one was 2 the other 3 years old. The same type of fiber damage as Curts claim.
When I measured the height of the beater bar while resting on the carpet the beater bar would come into contact with close to 1/2 inch of the fibers. This combined with the suction pulling the fibers into the beater bar cavity ,rpms,stiff bristles caused loss of twist and fiber abrasion. Resulting in the carpet to have a fuzzy appearance.

Also most of the manufacturers are only recommending suction only for carpets with cabled yarns and pile heights of 1 inch or more, they are lumping them together with the shag styles

I would be very interested in getting a copy of those "recommendations". I have checked with several manufacturers and they refuse to give written directions on vacuuming .

Re: Another carpet damaged by a Dyson vacuum.


Elmer Fudd, I agree with you. I would like the mills to fess up once in a while to us about special problems they come to find. I have known of the Dyson problem for at least 5 years. Have had customer's mention that they were told by "Karastan" (could be anyone actually) that a Dyson would void their warranty. Beaulieu recommends an "air suction vacuum" only for use in higher pile carpets in their on-line maintenance statements but does not specifically mention any manufacturer by name.
Dysons seem the worst offenders. Others do not seem to have brush bristles as stiff. Actually drew blood from a Dyson roller the other day. Thought the vacuum had snagged a staple or wire but the brush was clean. Some of the bristles had a sharpened point on them - ouch! I am sure that other vacuums do fuzz out yarn tips but the Dysons just do it really well.

Re: Another carpet damaged by a Dyson vacuum.


I've seen this with some Bissell units as well. Brushes are very short and very stiff. Last one I looked at was an inch pile with the Bissell set at the second to lowest setting (I think there were six or seven height adjustments).

Re: Another carpet damaged by a Dyson vacuum.


Shaw recommends using vacuums with a rotating brush or combination beater/brush bar that agitates the carpet pile and mechanically loosens soil for removal. Carpet with thick loop pile construction, particularly wool and wool-blend styles, may be sensitive to brushing or rubbing of the pile surface and may become fuzzy. In addition, shag (or cabled) styles with long pile yarns tend to wrap around the rotating brushes causing damage to the yarn. For these products, Shaw recommends a suction-only vacuum or a vacuum with an adjustable brush lifted away from the carpet so it does not agitate the pile. Be sure to test a vacuum with a beater/brush bar in an inconspicuous location before regular use, to make sure it doesn't produce excessive fuzzing.

Beaulieu recommends the use of vacuums equipped with a rotating brush or beater bar and brush for use with most carpet to loosen deep embedded soils. Certain carpet constructions such as Frieze, Shag and Berber tend to be sensitive to brush agitation, which can cause the pile yarns of these carpets to burst and become fuzzy. Beaulieu recommends suction-only vacuum models or vacuum models equipped with an adjustable brush and beater bar that can be placed where it will not come in contact with the carpet's pile yarns. Vacuums should be adjusted to the correct height setting for these carpets. The easiest way to do this is to raise or lower the beater bar and brush until the contact made is only enough to slightly agitate the carpet's pile yarns. If the vacuum motor slows during vacuuming the height setting is too low and the vacuum will damage the carpet. Vacuums that have been set too low also lose air flow, which is required to obtain the lift needed to remove soils and debris from your carpet.

Dysons seem to cause more actual fiber abrasion including the lower pile heights. And I had an Tech service person tell me that Dysons voided the warranty on Shaw carpets, but I have not found that in any warranty brochure or on the website.

Re: Another carpet damaged by a Dyson vacuum.


Ken, I agree with you 100%, but where is the mill standard?

What do you have to hang your hat on?

If taken to court, what industry standard, recommendation, or direction would you cite for back-up?

A few links that may be helpful:

CRI- the green label program info is interesting too. Note that Dyson,Bissell quite a few other common brands have not submitted their equipment for testing...

Don't have anything from Mohawk. Looked through their site and my tech files and nada...

Most of the wool mills have fairly specific vacuum cleaner qualifications, i.e. suction only. Seen a lot of felted wool berbers utterly destroyed with soft bristles too.
