Title: Numatic Henry
Post by: richardc1983 on January 07, 2005, 03:52:17 pm
been reading thru the forums and seen several posts saying about henrys and ppl hoovering with them when the bags are full.  Well to my knowledge these hoovers are still at full capacity wen the bags are quite full and i never notice suction loss wen that is the case.  What are u guys saying im confused.  Is it bad for the cleaner if the bag is quite full even though suction doesnt seem to be lost? explain please.

I've no experience with Henry's but, if the bags full, where does the dirt go? During use, as with all machines with filter bags, the performance DOES drop off due to reduced airflow. Also with reduced airflow, the motor will not be cooled so well, so reliability will be compromised due to over heating. Unless you use an electrically powered brush/beater head, a good upright will always perfrom better.

Safe and happy vaccing :)

Richard,

Often, long before the bag is full, the pores of the paper bag become partially blocked, reducing airflow. Placing a hand over the hose may indicate that vacuum power is still present but the airflow is the important factor in soil pick-up

If you are using a Henry to pre-vac prior to carpet cleaning you need all the airflow you can get. Even then it will not be as efficient as a good twin-motor upright or a good tub vacuum with an electric power brush.

A turbo head on the Henry does increase its' efficiency but the energy used to turn the brush head does reduce airflow.

Although we don't use a Henry for work, I have had one for about 10 years and use it for the car, matresses and hard to get at places.

The suction does get less near the full level on the bag.

At maximum fill, it hardly picks up anything...how could it? ???

I probably have always emptied then lol

I just use one for around the home for general use and find that because the pick up almost anything thats laying around i like them because of that.

I tend to find that every 2mnths or so is wen i replace the bag,

You don't have to use a bag in a henry at all.  Of course it will affect the life of the machine but then compared to the price of bags!  Also good to know in an emergency  ;D

Our Henry has often been used without a bag.

It has picked up building rubble, small bits of stripped wallpaper, ashes & soot, mud, cornflakes/ cheerios/ rice crispies etc., and it's perfect for sucking up big spiders at long range!!!

10 years old, rough & tough household punishment over the years and a really good friend (just for the spider removal).

Nicky ;D

John, are you saying my mate Henry is not a good tub vac, personally I believe it is a good friend .

IMO they are ok for commercial daily contracts, offices etc but not for us CC's. They are fairly well put together and providing they are not ran with to much resistance (full bag) they will probably never let you down, If you can afford twice as much the newer nilfisks take some beating they really have lots of vaccum.

Ian,

You only think he's your friend because he always smiles at you  ;D

Paul has pretty much summed him up - the daily office cleaner gets by with a 'crumb-picker'; as long as the visible surface debris is removed he is deemed to have done his job.

When it come to 'proper' carpet cleaning, what is required is to also remove as much as possible of the compacted soil at pile-base. To do this requires more air turbulence in this strata of the carpet and that is where the mechanical disturbance of brush action comes into play.

The brush action also opens the pile to facilitate the upward transport of the lower soil and dislodges some of the embedded and otherwise attached soil.

If you view the pre-vacuum as also starting the function of preparation of the pile to better accept the even distribution of both pre-spray and rinse solutions, then what can Henry and the like contribute - virtually nothing!

We'd never consider taking Henry out on a cc job.
He is a usefull piece of kit for the broom cupboard and that's all.
As John says, dry extraction needs to be far more powerful than anything Henry can provide.

Now did I say I take Henry out on a Carpet Cleaning job?

I said he was a great friend.


Would I give my customers an inferior service,

No.  I do find he sucks better on suites ;D ;D ;D ;D

However I have not got a Sebbo.

Personally I believe in British products. I wish ??? ??? ???

But cant the spiders crawl back out the bag or do they die as soon as they are sucked into the henry!!!

Also has anyone used the new henry turbo power brush with electric power brush?  They bout £170 they look really good.

Horses for courses.... henry's are excellent workhorses for commercial and domestic cleaning, regardless of the bag issue, as long as the filter is cleaned...  As a contract cleaner I would always recomend a bag, that's how they last so long.

tub vs upright... remember the advert in the late 70's, early 80's...

Beats whilst it sweeps whilst it cleans........... upright all the way for maximum dry soil extraction.

i agree with most of what has been said here,but no matter what you use,its enhanced by the person behind it! it can be the best vac in the world,but if you push it round 100 sq mtrs in 10 mins,it wont work,taking  time to do the jod well is the key,a sebo will pick huge amounts, on any pass, change the bag, and do it again very slowly,and you will be amazed at what it picks up again,dont rush any pre vacking,

Though of you who use HWE, why are you doubling up on machines surely the HWE vac side would be better with the right tools?

Len,

I do sometimes use the HWE with a dust-downer and electric brush head, but having a heavy hose to drag around, snagging on furniture etc. is not something I care to do unless I really need the extra power.

What about Numatic turbo head no need for the electric one less cable.

Title: Re: Numatic Henry
Post by: Dynafoam on January 14, 2005, 04:51:26 pm
Len,

A turbo head will improve the efficiency of a tub vac, but the energy required to turn the brush reduces the airflow.

When using a HWE with 300+ cfm this loss is not too significant, but my Victor electric brush head offers superior performance with no loss of airflow.

Similarly for mattresses and upholstery I have built an electric brush head. When it comes to dust, I'm a bully  :D

Not being a techno, what lift dose pro dry vacs give? We all talk about our machines what psi/cfm’s in dry vac terms it’s wattage. ???

You a bully??? Don’t think so!

Post by: Dynafoam on January 14, 2005, 10:14:45 pm
Len,

The 1200W vac unit of the Henry has a stated airflow of 45Ltrs/sec, which equates to approx 95.35 cfm (this figure will reduce when the resistance of the filter, hose etc. is factored in).

It's lift is quoted as 2600mm = 102.36 inches.

When I started I did not investigate the Vac market aswell as I should.

I do not know if Cleantalk was around in 2000 AD

Plus I might not have been the net junkie I am today

Thinking about with the exception of Prochem I do not think vacs were mentioned in any of the catalougues at the time

There was no suggestion of buying one as part of a start up package.


So I went out and bought a Dyson with Heppa filteration. Long before I had read  any of the  JP. and RS  litrature.  As I thought this was the most powerful upright and techniclogically advanced machine available tp man.


So how supperior in technical terms are The Sebbo and Victor machines to the Dyson.

My guarantee ran out years ago so it does not matter that I did not buy the Dyson that says Commercial.

And do they suck better than Henry on suites.
