Main trade-off
BISSELL Little Green Max Pet SmartMix
No standing upright floorhead for whole-room work
Head-to-head
Choose Little Green Max Pet SmartMix for localized sofa or stair spots and a lighter filled carrying load. Choose TurboClean Pet 3948 when a standing upright floorhead is more useful for room-sized carpet. Both still need compatible formula, wet-cleanable materials and recovery-tank care.
Before you choose
For two or three upstairs spots, Little Green Max's estimated 10.3 lb body-plus-full-clean-tank load is substantially below TurboClean's roughly 19.2 lb. Choose the portable when carrying and precise hose work dominate. TurboClean's floorhead earns its extra size when the job expands across a room. These estimates do not prove comfort for a particular user, and either machine becomes heavier if recovered water remains in the tank during a move.
What this is based on
Max uses 8.2 lb plus 32 fl oz of water, about 2.09 lb. TurboClean uses 14 lb plus 2.36 L of water, about 5.20 lb. Recovery tanks are assumed empty and accessories are excluded.

Compare Little Green Max Pet SmartMix and TurboClean Pet 3948 for stair carrying, room-sized cleaning, formula preparation and tank care.
Choose a lighter hose-based spot machine for stairs or a wheeled floorhead for whole-room carpet, accounting for the water carried.
Winner by situation

TurboClean's 7.5-inch upright path lets you clean carpet from a standing position, while Max asks you to work through its handheld hose tool. That makes TurboClean the more practical candidate for a room-sized route and Max the candidate for furniture edges or localized spills. TurboClean's 1.3 L recovery tank is only about 55 percent of its 2.36 L clean tank, so do not promise a full clean-tank run without a recovery stop. Actual recovered volume depends on use.
1.3 divided by 2.36 is approximately 0.55. It identifies unequal tank volumes, not how many minutes or square feet can be cleaned before emptying.
Max's SmartMix can handle the dosing step for its approved portable-machine formula, which is useful when a quick spot job would otherwise involve repeated measuring. That convenience should not be stretched into permission for arbitrary concentrates or an assumption that upright-machine solution can be substituted. Choose Max if this preparation step and its portable role match the job. TurboClean's standing floorhead can still be the better reason to choose for a room-sized carpet route.
The exact Max product documents SmartMix and compatible portable formula. This evidence does not establish the same automatic dosing feature for TurboClean, and no detergent-cost or cleaning-strength ratio is supported.
