<span style="font-family: trebuchet ms,geneva; font-size: medium;">For the "Monster Vac" competition when the club meeting took place here in Los Angeles, I did something similar with two Electrolux Model Ss. </span>


 


<span style="font-family: trebuchet ms,geneva; font-size: medium;">The results were disappointing -- there was no more suction with the two machines coupled together than each one singly. Something about how two motors of equal power canceled each other out, I was told. </span>


 


<span style="font-family: trebuchet ms,geneva; font-size: medium;">I wonder if having the "Y" connector further away from the machines, as with the Twin Filter Queen model, might make any difference. </span>


 


<span style="font-family: trebuchet ms,geneva; font-size: medium;">I also used a long 2"-diameter commercial-type hose connected to it, about 12 ft. long, and the Model XXX commercial-length floor brush (1.5x longer than the normal attachment). That may also have impacted the performance but I don't know.</span>

If you hook up two motors like you guys both have it is air parralel you will get more airflow but as their is more airflow you will loose some lift ( suction)


 


It also has to do with friction, the longer the hose the more airflow you will loose in friction. I am not familiar with the USA electroluxes but if they have a blowing port you could technically put the suction hose from one machine into the other machines blowing port. this would give you more suction like having 4 fans on one motor, this type of system is used on most portable carpet cleaners as you need lift to get the water out of the carpet. industrial tangental motors ( ones with the exhaust are designed for this with seperate cooling fans for the motor, with the thru flow motors used in mst domestic vacuums you could nd up overheating the motor.This would give you twice the lift but reduce you airflow by as much as half
 
there should be a bit more suction than a central vac , remember a central vac looses some of its power thru frictiondue to the long hoses and internal pipe work , thats why they use those huge motors. 2inch hose would also help improve the suction , less friction.


 


When I owned my carpet cleaning company I built a truck mount using 4 amatek big boy motors , the same found on many central vacs , two in air parralel and the other two hooked up to the first two in series, that machine crushed a 50 gal drum I was using as a vac tank , I had to get a re inforced one made.
 
It's funny that you did that because I had that EXACT same design in my head years ago! I would love to do it sometime...
 
yup..

I have had this idea perculating in my imagination for the past two years.... I felt very inspred to take action on it....Now i will work on perfecting it... soo stay tuned....

thanks for your sharing..

just make sure the two machines are in similar condition , if one motor is weaker than the other the stronger motor will pull the weaker one making in spin faster than it should and prematurly killing it, talking from expeariance here.


 


I used to work in the r&d motor department for a vacuum company so I got paid to blow motors up, what a job. I learnt a thing or two there. I once built a vac tank with 5 motors on it for an experiment. bloody noisy. 


 


Have fun
