I received the model 2998 that i ordered in 4 days, if was missing one of the 3 prefiltersand when i called this gemtleman, very nice, said it would ship it right out. It wasnt the one i needed and was told not to u se the vacumn without it, my second call was received by a very nice woman who told me they were back ordered, and i was frusttated, she ended up sending me a whole new vacumn. Very nice of her. Now when i get the filter i will find a new home at the closesr sheltert
