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...

I think that I read that central vacs are measured without a hose.  Length of hose will impact air watts.  No wonder my air watts are low.

This is once again a case of, "If you dazzle them with brilliance baffle them with BS."

Even machines with the best suction lose something in the translation by the time you get airflowing at the hose end or floor nozzle. Body seals may not always be tight enough, hose connections may also allow for leakage and even friction may diminish suction. (One of the reasons that household vacuums never usually have overly long hoses.) Badly designed wands and attachment locking mechanisms may also attribute to the same.

Not many manufacturer are up to the challenge of honsetly stating what suction measure as at the motor's air inlet and the final percentage of a hundred percent that finally arrives on the floor or at the end of your hose.

If we had vacuums that could deliver a close percentage of hte motors actual draw, we could again use machines that use less power

I can't recall saying that a good brush was vital.  I would still take straight suction and NO brush as opposed to a great brush and NO suction.  The latter is like the old bissell sweepers or an Oreck.

All carpets do not require the same type brush.

HS:

I would take both on rugs over one or the other exclusively.  Fortunately in today's vacuum market both are offered by all brands and most models.

Hi Venson:

The advantage of the fan first uprights of years gone by and ORECK and a few others still today.

Airwatts, cfm x waterlift divide by 8,5

My F,A,S,T, intake throttle body has 1100 airwatts, it doesnt clean very well though.

H.S. all the numbers can be manipulated,all depends how they want to market the product,

In the central vacuum industry any thing over 400 airwatts is considered powerful ,its just a # game............

Would it be legal to put one of those 6500 rpm Oreck motors in the exhaust to help the flow?

THanks for saying what I was trying to get others to say.  Manipulation exists in all industry.  The best test is hand on experience.  Forget the marketing hype.

when you use  that formula , say on a 750 w lamb motor with 112cfm and 63 in w/l it comes to abt 830 aw....yet there chart says 190aw...what gives

Hi turtle,your getting very quizy about the #, the formula the rest of the story goes like this,cfm x W/L divide  by 8.5 take that # and divide that by the fan case opening most are 2'', now your at the right #,still means nothing in real life applications,

Do you really think a Z06 corvette puts 505 h.p. to the ground?Its just a  engine dyno number thats never achived in real life. The lamb/ametec electric motors are rated the same way, strip the fans off the motor throw a 240 volt charge into it and blow it up,but the motor made 4 hp, do you see the game yet?

Do you realize that the most overlooked piece on the vacuum are the attachments............
