Oh dear, here I am again with my disappointment. Sorry guys but I can't moan to my partner so need to express my feelings here
Even though I wipe the bin after each emptying, the pre motor filter gets dirty very quickly. I've washed it once and it noticeably dirty again.
Besides I discovered that the seal around post motor filter doesn't really do much. I would think that the air should only come out through the gap in the plastic cover. But it actually blows all around the filter, around the edge where the vacuum meets the filter.
I had Ball Animal 2 for six months and it didn't get as dirty behind the cyclone mesh as the Small Ball did since I bought it which was less than a month ago.
And what is worse I think that the cleaner head might be going. Sometimes it takes some time for the brush roll to turn on or off and the Max switch also sometimes doesn't want to switch
so I need to move it from one side to another.
