My Dyson wasn't sucking that well, and I decided to investigate. There's a little blue button on the front, which says "Filter" So I pressed it to investigate. (Never done it before

) Anyway, I popped the thing out and it was absolutely FILTHY!!! Around the edge, it said that they should be washed every 3-6 months

Anyway, I washed it in some well diluted Ecover multi surface cleaner, until no more muck came out, rinsed and dried it, put it back in this morning (It took a couple of days on the boiler to dry) and it seems like I have a new machine!! It's sucking so hard again it's an effort to push it over the carpet! Brill! If you've got a Dyson, and have not done this, do it now! (Well you probably know this anyway, and do it regularly 0 it's probably just me!)
