Perfect fit, 11s running like new!
Style: with Pre-Filter
All parts fit perfectly. My vacuum lasts about 20 min longer since the filter isn’t clogging it. Also, replacing the spinning brush quieted it down significantly, it sounds like new again.

Good quality and good value
Size: 2+6+1+12 Pack
this is a great deal and so nice to have on hand. I like being able to just grab replacement parts as needed and not have to place orders for them. It gives peace of mind to know I already have them on hand. much more affordable to buy all at once too
