Dustbusters

Page 1 of 2  
Yesterday I was cleaning the gaps between my floorboards prior to painting and the ordinary Hoover (actually it's an Electrolux) was being a pain, as the hose is really bulky when you're crouched over the gap with a broken hacksaw blade, freeing up the fluff.
So I thought, I know, I'll pop down to Currys and buy a Dustbuster. But when I viewed what was on offer, I went back home again, Dustbuster-less. These things look so tacky, they are the epitome of complete crap. Plasticky, flimsy in the extreme, they look as if just a strong grip would bust *them*. Not one was suitable. Currys had a Hoover, a Carlton (some no-name brand), and about four different kinds of the Black and Decker Dustbuster. Also, the prices! £37 for a Dustbuster, when I can buy a proper vaccum cleaner for not much more. And that was not the most expensive. Another thing about the design I didn't like: They all seemed tremendously cumbersome - great chunks of plastic, not compact, small handy tools like one would imagine. Useless.
So, Black + Decker, Bosch, Siemens! I know you all peruse these groups. Hang your collective heads in shame at such rip-offs and design something that is about the size of a blowtorch that looks like it might last a bit longer than the trip home.

I bought something similar a lot cheaper from Lidl - it's completely useless.
The advertisements on TV prior to Christmas for the Black and Decker (??) showed how good it was at sucking up puffed rice breakfast cereal. I guess that's just about the limit of its performance.

Which sucks more... The dustbuster or Currys?

On a sample of one I have found Curry's customer service to be excellent. My Grundig freeview box packed up after a few months. I had no receipt or packaging so I put it in a Tesco carrier bag and took it back to the shop, expecting a fight. I was immediately disarmed by the member of staff who said "no problem, just take it to the till and they'll organise a replacement for you". They were able to confirm my purchase by entering the date (from my credit card statement) into the till and searching for my name. A duplicate receipt was printed and I was presented with a replacement, more expensive, make (The Grundigs were out of stock so no extra to pay). It must have taken less than 10 minutes.

Got a B&D Dustbuster here and am very pleased with it.
Saves getting the vacuum cleaner out of it's hole for minor stuff.

You are correct about the cheaper Dustbusters not sucking very well, however the 9.6 volt version is excellent.
They are pretty resilient, the only doubt being part of the wall bracket which I have repaired. It is adequate for vacuuming the stair carpet, and deals happily with the eating mess created by two children under 5. They are not cheap though.
Tesco are currently selling a Samsung 1400 watt cylinder vacuum for £19.99. It was £60 according to their adverts and a friend who has bought one tells me it's great value for money.

£19.99.

I bought one of those last Monday (I thought they were good value enough and it sucks quite well) to use for a dust extraction system. If it doesn't work, what have I lost, but 20 squids? It's only drawback, is the size of the dust bag. It's tiny.

To over come the small bag use it as the suck for a cyclone separator (dustbin, bucket, some rigid pipe and another length of hose). As dicussed several times in here.

That is just what I intended to do, but I have a couple of questions about the bucket used for the inner part of the cyclone. Is the diameter and depth critical to its operation?

Just a thought, if Dave Liquorice has replied to me, I can't see his posts. I asked about this some time ago and others thought that I might be running a kill file. The last time I was missing his posts, I was running windoze 98se, now I am running XP and still not seeing his posts. As far as I can see, it is only Dave's posts that do not appear from my server (btinternet). and have never put a kill file into use.
Any ideas any one?

Sorry for the delay in responding....
I expect the answer to that is "yes and no". I doubt it makes that much difference - the main purpose of it seems to be to help get the air rotating and also to prevent a direct path for dust to be sucked from the input to the exhaust.
I am sure if you analyse it scientifically, you would find that it will effect performance - but probably not enough for you to care in this application. (if you did not have the added filtration of the vacuum cleaner to follow then you would need to pay more careful attention to the smaller details).

Don't worry, we all have lives to live :-)

Initially, I was bothered about these details in case I filled the source vac with dust too quick, but when I looked at how it worked, I very quickly found out that what was required was that the speed of air going in had to far exceed the speed that it was drawn out, hence the large diam. of the bucket protecting the suction device.
If the bucket was too deep, there would be less collection capacity.
If too shallow, there would be more dust passed to the suction device. I think this aspect should be considered with the height of the inlet pipe to the chamber. The higher the inlet, the shallower can be the bucket portion.
If too wide, it may hinder the passage of the dust to the more stable lower chamber of the cyclone.
If too narrow, the speed of entry of the dust would be close to the speed of extraction

A simple cloth filter at the bottom of the bucket would sort that out and could be made to be cleanable from a small diam. shaft, connected to the filter, that would enable the dust to be shaken off from above. Pump the handle up and down a few times to shake off the dust collected. With the suction device switched off of course.
All I have to buy now, is the input and output pipe and I will still have change from a tenner :-)))))))) Not that I am tight, you understand ;-)

Ultimately the speed in and out must be the same though because the collection hose from the vacuum supply is the same diameter as the dust collection hose.

true
In theory so long as it protects the incoming airflow from any turbulence generated by the exhaust then it should be fine.

Yup - planer shavings etc.

Can only see that becoming an issue when the bin gets to nearly full - the faster airflow up the smaller bucket may be able to "lift" some finer dust from the top of the pile, whereas, a slower airflow in a larger bucket will be less likely to do this.

Not sure a cloth filter would help much - the only stuff that gets as far as the vacuum bag is as fine or finer than talcum power - and that would either pass through a cloth filter, or possibly form an air tight clog.
If you want top quality filtration with no "filters" as such anywhere in the system, then you would probably be better off with a different design (i.e. one that has a conical cyclone section that sits above the collection bin rather than combining the bin and cyclone, and one that uses a long straight input pipe (i.e couple of meters). That would ensure best quality airflow in, followed by much greater acceleration of the air speed in the cyclone - that way you could spin out stuff as fine as smoke particles)

It's normally the extra hoses / adaptors that cost the money!

Sorry, but a slight correction here :-)
The speed is dependent on the diameter of the pipe in question. I was thinking about the diameter of the bucket. Volume, I think, is what you meant.

OK then, the filter has been binned, thanks again.

It's only a hobby ;-) All I want to do is stop me from changing the colour of the garden when I DIY (I have to work outside, due to lack of garage/workshop. It's a PITA, but what else can I do but wait for dry and non cold weather :-(

Thankfully, I have most of those, it's just the rigid waste pipe I have to buy now.
I know I have said thanks many times in this post, but you have taken me from not knowing much about how they work, to almost an expert ;-)

sort of - yes it is volume of air (as in m^3/hr) that must match in and out - but note I did say the hose diameters at the tool and the vacuum supply are about equal - hence the air speed at the hoses will also be about equal. Having said all that, part of the purpose of the bucket in the type of design we are using here is to make this a "non issue" since the exhaust hose never gets near the top of the collected shavings in the bin.

Its probably not an issue to worry about - it would be mechanically difficult to have a gap between the outside of the bucket and the inside of the bin that is less than the diameter of the inlet hose. Hence if it gets all the way down the hose it is less likely to get stuck then (more likely to get stuck in the hose)

Part of the attraction of the cyclone anyway is not having to worry about filters/bags etc any more.

Well the unit I built will certainly handle that requirement. I use my one for all dust collecting and general cleaning up in the workshop. It's fine for hand tools etc and things like the table saw. I expect something with a bigger diameter input might be good if I got something like a thicknesser or a bench planer though.

Aha - perhaps you need to have a bash at one of the other projects that pre-dated the need for the cyclone...
(think this link is still in another thread some place - so you may have seen it already)

(I had the similar problem to you - either work outside, or work inside and incur the wrath of SWMBO. Neither were ideal for any job that you needed to stop and start over a few days)

Must admit I found having the fixed plumbing from vacuum to cyclone was a bit limiting as the collection hose was not always long enough to get to every place I wanted it. So I scrounged an old set of vacuum tools from my mum's under stairs cupboard! That works quite well as I now can move the cyclone itself a couple of meters when I need to.

Well I would not claim to be any sort of expert myself on cyclone design - but fortunately they don't seem that sensitive to design in this application! ;-)

Hughey Green would be my guess?

PITA,
LOL That road looks very familiar :-) Gone down that sort of path before, usually because of the wife's butterfly mind.

One day I might get a shed that can have the tools set out, but I'm not holding my breath.

I bought a lidl one for 9.99 it is very useful for odd small jobs. However I would not recommend it for diy stuff. It has not got the capacity and fills up too fast. However for ten pounds with a two year guarantee it is great. I had a dustbuster before and that had similar problems. I would recommend a small hoover dedicated for diy. You can always modify the hose end for a special application or even take the nozzle off which is usually the most practical for the job you mention.

I sold a Delta one on Ebay that someone had given me rather than chucking it out and the cheeky buggers want to return it and their £3.20 refunding...
