wall chasing vacuum
Hello,
I have been using my Earlex vacuum connected to my wall chaser. I use the dust bags which I have bought from Earlex (are generic ones just as good?). The Earlex web site says their bags filter to 5 microns. I have found that when I do the first chase, the vacuum seems to suck up everything. I noticed that as I do more chases, more dust begins to fall from the chaser, escaping the vacuum. I assume the bag clogs up. I think it would be extravagant to change the bag every time I start a new chase! That said, I can't grumble because the amount of dust falling is tiny compared to not having the vacuum on at all. I forgot to put the hose on the other day and there really was a difference! The bag was getting heavy the other day so I emptied it and it was full of fine dust, so it is certainly doing a good job but I remember a thread here where someone said the only vacuum he found that could cope with repeated wall chasing was a Dyson. Looking on line, it seems the Dysons filter to 0.1 micron, so would capture even more. Should I be content with what I have got or is it worth getting a second hand Dyson just for this? If so, is there any particular Dyson? I seem to remember DC04 and DC07 being mentioned before. What are the differences between them? Does it have to be an upright? I think someone mentioned making a prefilter from a bucket. That's a good idea. Does it work just as well? My only worry is that with two hoses, one prefilter, and one vacuum, that's quite a lot of things to get in the way and trip over. Thanks, Stephen. |

As you've discovered, a bagged cleaner is useless for the volume and rate of dust generated by a wall chaser. You have to use something which keeps the collected dust out of the air path. If so, is there any particular Dyson? I seem to remember DC04 and DC07 being mentioned before. What are the differences between them? Does it have to be an upright? I've used a DC04 and DC07. Both work well. The DC07 is a more recent and powerful model, but it has more smaller channels which can get blocked by house dust if the thing has been used with a grossly over-fulled dust container. Dust from the wall chaser won't block them, but if the cleaner is of unknown origin, I would dissasemble the top and blow the channels clear before you start. Check the washable pre-motor filter too and let it dry if it needed washing. (I've never had the post motor filters on any of the family's Dysons get dirty -- I think you would have to abuse very badly to do do that, such as grossly over-fulled dust container whilst also removing the pre-motor filter. The dust canister will be very heavy when full of plaster/brick dust, heavier than the handle is designed for, so beware of that. The brick dust will also sand-blast the inside of the canister, which doesn't affect operation, but SWMBO might not be happy that it no longer looks like new. Keep an eye on the pre-motor filter. Providing you don't grossly over-fill the canister, it should last a day's chasing (many canister empties). Rinse and leave to dry overnight. (I bought a second one so I could swap them whilst one is drying.) I think someone mentioned making a prefilter from a bucket. That's a good idea. Does it work just as well? My only worry is that with two hoses, one prefilter, and one vacuum, that's quite a lot of things to get in the way and trip over. If you're stuck with a bagged cleaner, interposing a cyclone before the bag will help. Constructing a cyclone which really separates out the finest dust isn't easy and it's this that either cloggs or passes right through the bag, although the type of dust (heavy) involved here is the best for cyclonic separation. Other thing I would suggest for a non-Dyson cleaner would be make sure the air outlet is directed outside, if you don't want the house filled with fine dust. (Dyson traps all that, so not an issue in this case.) -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

wall chasing vacuum
somewhere on this newsgroup was mention of a vortex
vacuum bucket thingy to get lumps of grit before the vacuum cleaner, where was it? [g] |

A cyclone certainly does a good job. But dyson's reputation is enough to keep me well away, there are better makes about. If so, is there any particular Dyson? all have plenty of suck and a cyclone, as do some other brands. I think someone mentioned making a prefilter from a bucket. That's a good idea. Does it work just as well? My only worry is that with two hoses, one prefilter, and one vacuum, that's quite a lot of things to get in the way and trip over. That removes the bulk and much of the dust, enabling a small cleaner to work, or a cyclone to run for much longer before emptying. I've also heard of a tub of water being used to filter, but never seen it in action. One thing that differentiates cyclones is the filter that's used after the cyclone before the motor for the finest dust. If its just a small bit of sheet material its gong to clog easily. If its a big fat porous sponge disc, the muck has to somewhat saturate the sponge before it stops sucking. NT |
