The Big Green is the one Bissell that is engineered like a rental machine rather than a household appliance. A 12 amp motor, rotating DirtLifter brushes and a 1.75 gallon clean tank are the specifications that separate it from every other upright in this roundup. It also cleans on both the forward and the backward pass, which matters more than it sounds, because every square foot gets two passes of spray and suction without you doing extra work.
The cost of that capability is mass and bulk. Filled, the machine is a heavy thing to walk up a step, and the 9 inch hose is a short, stiff reach for upholstery rather than a true stair tool. Compared with the TurboClean Pet XL, which is lighter and has a 10 inch path, the Big Green wins on tank volume and brush aggression but loses on hauling convenience.
Plan on rinsing both tanks and pulling the brush rolls after every job, because stored wet they turn sour inside a week. The dirty tank is large, so a full room is a single trip to the drain rather than three. If your carpet is mostly open floor and you clean twice a year, this is the machine that earns its closet space.
