I read tips that you can put a nylon sock on the filter. NONSENSE! The motor heats up and can quickly fly to another world. It is better to wash the filter every time (it can be easily disassembled) and purchase spare filters from ALI. For cleaning the kitchen, I was quite satisfied with the vacuum cleaner. For carpet, I have a huge Dyson, and it was hard for me to carry it around the kitchen, which is why I bought this baby.
