Walmart offers the Bissell PowerForce Helix Bagless Upright Vacuum
in Blue, model no. 1240, for $47.84
. Opt for in-store pickup
to dodge the $4.97 shipping fee. (Alternatively, you can pad your order to over $50 to bag free shipping.) That's tied with our mention from two weeks ago as the lowest price we've seen. (It's a current low by $28.) It features the helix dirt separation system, five height adjustments, and washable filters.
