Everything fitted perfectly but the instructions were barely adequate. I would definitely pay close attention to how you take things off so you can put everything back on properly, especially with regard to the little metal clip that holds the tubular microfilter in place. Also, the only way to find the exhaust filter housing is to release the latch on the handle and lay the Sebo flat, like vacuuming under the bed. The outlet filter housing is located in the Sebo base just below the filter bag housing. I didn't know what sealing tape was, but once you find it under the base near the roller it's pretty easy to see that you just slide out the old and put in the new. A good tip I got from someone on the internet: you can keep one of the green plastic filter bag caps inside the filter bag housing under the bag where you can conveniently close the full bag when you change it.
