    It is a Dyson DC30, and we paid roughly £90 for ours. We also have a lot of Dell Optiplex's on site, as we use it for cleaning the front grills on the cases. It's very good for this.

    That's when I actually get any time to clean things. Most of the time the cleaners do it.

    Last time I replaced all our (rubbish S@nyo) projectors with Taxan DLP units with NO filters!

    These have proved very reliable, just needing a vacuum out every couple of months...just coming up to three years old and I am replacing all the bulbs for first time.

    ...the new bulb is so much better than the old one that teachers think I am working some sort of miracle and I am VERY popular at present

    Most of the time the cleaners do it.
    I have asked our cleaners not to clean IT kit as they always wipe it over with the same mucky cloths they wipe all the desks etc with!

    Biggest problem is the ridiculously small size of the filters compared to the airflow pulled through them in a normal working day. We clean ours monthly and come the following month, some look as though they have never been cleaned ! As for the projectors fitted in the Home Ec dept ……..

    Some of our projectors require cleaning more frequently but we do not have the manpower to do that, which brings me to my next comment. I would have liked to have asked the Epson trainer mentioned by CapEnd earlier, why projector manufacturers like Epson fit such small filters in the 1st place and then expect them to last a reasonable time without clogging.

    Clean ours when I can get the time, usually do all of them at once (although takes a couple of days to get around them all!)
    This year on the other hand I will be taking the same stance as others on here and doing them when the lamp goes bang, since theres now only me here!!

    First generation Hitachi short throws I find to be a pain for dust/overheating. The filter is miles too thin and as the fan is huge it soon fills up. Newer ones come with a thicker 3M filter (which the manual says will come with any new lamps) 2 new lamps so far, no new filters in the box!! And I agree with projectors in cookery rooms....'shudders'

    I would suspect it is a uni-cycle ......lol (I have a 5')
    Anyways, have any of you tried out projector enclosures, I have an acquaintance that has installed several and said they work great for minimizing cleaning and overheating.

    Thanks....

    Just done most of ours but some classrooms are being painted and all of the furniture has been heaped under the projectors, so I acan't get to them. It's interesting how some are much dirtier than others. I don't know if that's down to them not being turned off or just dustier kids?

    I can tell which cleaners clean which rooms in terms of standard classrooms, obviously catering, textiles, art and DT tend to be fluffy/dirty/greasy due to the nature of those rooms and the way they are, however a standard classroom for english or maths doesn't differ much yet cleaning standards do unfortunately
