Almost every site is trying to sell a vacuum. What I saw on a reddit post is exactly my issue. There's a opening on the side below the dust canister that starts sucking air, reducing the suction in the hose. I took ours completely apart. There's a spring/valve-like mechanism on the inside that allowing suction thru the spring-valve instead of completely through the hose/canister assembly like it should. Now all we need is someone to explain how to correct it. Like a new spring valve assembly piece. Anyone??
