Since the bin is bagless I think there needs to be filtering somewhere, but I can't vacuum our house (2000 square feet) without cleaning / Change the filter bag cup and at least once disassemble the canister and remove lint / pet hair from all sides of the inner inlet piece. (See, I'm not an engineer so this is a gizmo). The thing is, when the filters and air intake are clean, they have really good suction, but they easily clog and stop the whole process, and this happens at least once during the vacuuming process. I would neither buy nor recommend this product.
