I know I'm probably the only person in the world that feels this way but I am so over these vacuums with the filters on them and the canisters that have to be emptied. Give me a bagged vacuum cleaner any day. I'm not that big of a moron that I don't know what size bag my vacuum takes. LOL
My latest vacuum is a Bissel and has a washable filter. Once I washed it the first time, it needs to be washed every single time that I vacuum now. If I don't wash it, everything gets clogged and all the dirt/debris goes to one side of the canister, fills up and clogs another part of the vacuum. And to clean the filter is a disgusting mess.
I also cannot stand the mess of the canister. Of course for presentations they show everything all nice and tidy in the canister and then easily dumped into the trash. In reality, my canister gets dog hair and other dirt/dander that flies everywhere when the canister is dumped. I have to open my trash can and put my canister far down into the bin, dump it and make sure I close the lid quickly before dust, etc. is flying around.
