This is something I used to do, but stopped doing, as I reckoned I was just wasting my time, but perhaps I wasn't...

Here is what I used to do:

Get the cleaner out, plug it in, turn it on and let it run for 15-20 seconds in the upright position before using it.

"Vacuum Village" - The spare room is pretty cold as the heating is never turned on in it, so that is partly why I used to let the cleaners run for a wee while.

Should I start doing it again ?

....I don't know that it's necessary to warm up a vacuum's motor, but I always make it a point to be certain a hose is warmed up in a warm room before using it. Cold is hard on hoses. Uprights with a bit of hose between the base and dust bag connection could probably do with this treatment as well, though I have no personal experience with uprights.

Not quite the same as warming up a vacuum, but I read a thread where it was suggested to pulse the motor on and off if you are testing a vacuum that hasn't been used in a long time or one you aren't sure of the bearing condition.

There is absolutely no need to warm up a vacuum. Its a vacuum, not a Cummins turbo diesel.

Ha ha, very true, although, my '77 Ranger sounds like a Cummins! The seller who I bought it from said he'd replaced the brush roll bearings recently... Hmm... Not too sure 'bout that!

Oh well, it adds to the "character"...

Its a bit strange but, yeah I have 'warmed' up my machines before proceeding to vacuum. My Dyson DC24 makes a horrible noise when first turned on, its something to do with its exhaust filter seal which is normal. Once the noise has gone away, I then start to push my machine across the floor. The noise goes within 10 seconds.

My previous Dyson DC04 motor used to start up when switched on but the motor slowed slightly and then sped up, it was only ever so slight and U would only notice, if ur someone like me who notices everything. It was fine fine for 8 years and this only happened within the forst 20 seconds of use from 'cold'.

What about Caterpillar motors?We have a Cat genset here at work-guess you could rig up the air intakes with a bag and filter--there is a lot of suction there when the engine is running.And two of these inlets-so could the rig be set up to run two vac hoses?A new type of central vacuum.And there is a HEPA filter of sort on the intakes already.

That is NOT a good idea. No offense. WAY too much potential for killing a turbo.

No,I wouldn't try it either.Just use the thing as intended-a generator.Use it to POWER the central vac!

As it was said before about the cold hose being stiff, same goes for all other plastic parts, especially older plastics or really cheap vacs with low quality materials. Cold plastic breaks easier.

So basically, I could warm it up, or just be gentle for the first minute or so ?

Given that the exhaust air seems to get warm in a reasonable amount of time, I've found that using my Lux canister vac in blower mode makes an excellent hair dryer for my dog after a bath. The air is a nice temperature without getting too hot.

"or just be gentle for the first minute or so ?"

Yes - that way it will still respect you in the morning!
