Vacuum Cleaners Discussions

Did anyone notice that the DC11 is back on some of the Dyson websites... Here's one that I thought was gone forever...

Hello retardturtle1:   This is for HS's benefit too and others here who cry foul whenever I say what I think about their fave brand, company and models.  A dyson I actually liked was the All Carpets which was a Wal*Mart exclusive in 2003.  No gawdawful noisey problem prone clutch.  Sold new for $319 but discounted for $278 and less.  It wasn't the best rug performer sold, due to the whimpy brush, but okay.  Dyson and W*M srubbed it in short order.  W*M scapped it in favor of a 2 year dealer with the HOOVER FUSION [TTI produced] in 2005.  The FUSION was a huge seller for W*M.  Perhaps dyson was pre-empted from reusing the All Carpets due to its contract with W*M.  Sort of like Japan and the DDM.

The DDM DC22 was supposedly launched at the VDTA in Feb 2009 to be a dealer dyson here in the USA.  Best kept secret in the vacuum industry in 2009.  It did a Claud Rains and became invisible.  Did dyson need the money so took the deal with Japan?  Maybe some of the dyson insiders here will say.  Maybe not.

I suspect that the reason the DDM motor is not widespread is cost.  If they can get fairly good performance from a proven Panasonic motor that costs $50, why switch to an unproven motor that costs considerably more.  Japanese household are willing to pay a premium for small items.  Space is less of an issue in the US, so we would not be willing to pay a premium for a compact vacuum with a special motor.  As others have noted, it's not the suction that is the weakness of the Dysons, it's the brush roll design. 

on the brushroll, one would  think that DYSON would copy a proven design...i mean if it works with what you got..then it works....btw..is the DDM a 1 fan or 2 fan motor for cans only? but i can see some of the american public buying a limited ed....with DDM....some who wont mind the hefty increase....due to the advanced DDM. i mean we are the land of too much power is never enough....slip it in with a shipment.....coming this way anyway..... i also feel that we all can get wrapped up and  wowed by good edgy advertising..a huge budget  ..and look past the unproven part....running straight for the nearest dealer...just cause its new and first of its kind.

You may know this already so forgive me if I'm being redundant.  The pano motor that Severus speaks about which is installed in dyson's DC07 uprights is a one fan reversed wired pano motor that has been in the US vacuum industry since the early 70's.   Good motor but standard issue.  Not the TOL tri-force pano motor that's used in the TOL pano uprights and canisters.

I don't know what components and in what quantity are in the DDM.  Interestingly, dyson went from one of the least expensive industry sourced standard issue motors for its first upright launch in the USA to a sophisticated esoteric non-standard vacuum industry motor for the DDM.   The timing couldn't be worse in light of the global recession especially in the USA where dyson at one time boasted two thirds of its vacuum market sales.

The Dyson Digital motor is a one-fan only design. Apparently the fan is curved in three dimensions, design cues came from the aerospace industry, and it is made out of PEEK plastic.

Hello Trilobite:

Thanks for the DDM motor schematics.  Very interesting. 

Your pictures pigued my interest.  I checked the official dyson specs of the canisters on the dyson UK web site.  Interesting results.  Dyson's 5 year old DC11 with an encore presentation has 275 air watts.  Newest dyson DC19 T2 cann has 280 air watts.  DDM DC22 has 200 air watts.  200?  That's a far cry from full size power.   I'm even suspect of the nice even 200 number.  Does the DDM motor actually deliver suction power equivalent to industry standard vacuum motors?  Especially at the exorbitant price.  The reason for the smallish 7 inch rug nozzle on the DC22 may be the lesser suction power and not the maneuverability in tight spaces.

HI CARMINE

nothing to forgive...thats  what the forums all about..Q&A, ...ideas..learning ..fun stuff....anyway, i knew the 7 had a pan motor...but why rev wired...? and i have no clue abt where the other motors are from..but i think the DDM was in one of  his earlier cans .[not sure]..guess the timing is bad at the moment for a chunk of change on a vac... that is an  intresting  looking motor tho...i never seen a motor like that. so whats your take on it ?

TRIBOLITE...

Yes ,,thank you for the all the info  and i do find it to be an intresting design....but as CARMINE said...200 a/w is ALOT lower than 280...not seeing where this motor is supirior over all the rest...or how it can overcome a 40% a/w loss..
