The catch
BISSELL Little Green Max Pet SmartMix
Whole-room work has no standing upright floorhead
Side by side
Little Green Max Pet SmartMix suits localized sofa or stair spots and a lighter filled carrying load. TurboClean Pet 3948 suits room-sized carpet, where a standing upright floorhead is more useful. Both still call for compatible formula, wet-cleanable materials and recovery-tank care.
Before you buy
For two or three upstairs spots, Little Green Max comes to an estimated 10.3 lb with body and full clean tank, which is well under TurboClean's roughly 19.2 lb. The portable is the choice when carrying and precise hose work come first. TurboClean's floorhead justifies its extra size once the job spreads across a room. These estimates do not prove comfort for any particular user, and either machine gets heavier if recovered water stays in the tank during a move.
Where this comes from
For Max, take 8.2 lb plus 32 fl oz of water, about 2.09 lb. For TurboClean, take 14 lb plus 2.36 L of water, about 5.20 lb. The calculation assumes empty recovery tanks and leaves out accessories.
The catch
Whole-room work has no standing upright floorhead
The catch
Starting weight with a full clean tank is about 19.2 lb

Stair carrying, room-sized cleaning, formula preparation and tank care are where Little Green Max Pet SmartMix and TurboClean Pet 3948 are compared.
Take a lighter hose-based spot machine for stairs, or one with a wheeled floorhead for whole-room carpet, and allow for the weight of the water you carry.
Which one fits
With 32 oz of water, Max comes to approximately 10.3 lb. TurboClean, with 2.36 L, is about 19.2 lb, before accessories.
TurboClean has an upright cleaning path of 7.5 inches, while Max works through a handheld hose tool.
Localized hose work suits the lighter portable format of Max. TurboClean can use its supplied above-floor tools too.
SmartMix is documented for Max. The reviewed record does not establish equivalent automatic dosing for TurboClean.
In practice
For two or three upstairs spots, Little Green Max comes to an estimated 10.3 lb with body and full clean tank, which is well under TurboClean's roughly 19.2 lb. The portable is the choice when carrying and precise hose work come first. TurboClean's floorhead justifies its extra size once the job spreads across a room. These estimates do not prove comfort for any particular user, and either machine gets heavier if recovered water stays in the tank during a move.
For Max, take 8.2 lb plus 32 fl oz of water, about 2.09 lb. For TurboClean, take 14 lb plus 2.36 L of water, about 5.20 lb. The calculation assumes empty recovery tanks and leaves out accessories.
With TurboClean's 7.5-inch upright path you clean carpet standing up, whereas Max has you 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. The 1.3 L recovery tank on TurboClean 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. The volume recovered depends on use.
Dividing 1.3 by 2.36 gives approximately 0.55. All that shows is unequal tank volumes, not how many minutes or square feet can be cleaned before emptying.
SmartMix on Max takes over the dosing step for its approved portable-machine formula, which helps when a quick spot job would otherwise mean measuring again and again. Do not stretch that convenience into permission to use any concentrate, or into an assumption that upright-machine solution can be substituted. Choose Max if this preparation step and its portable role fit the job. TurboClean's standing floorhead can still be the stronger reason to choose it for a room-sized carpet route.
SmartMix and compatible portable formula are documented for the exact Max product. This evidence does not show the same automatic dosing on TurboClean, and it supports no detergent-cost or cleaning-strength ratio.

Spec by spec
| Spec | BISSELL Little Green Max Pet SmartMix | BISSELL TurboClean PET | In practice |
|---|---|---|---|
| Empty weight | The machine weighs 8.2 lb. | The empty machine weighs 14 lb. | Before liquid, Max weighs 5.8 lb less. |
| Tank volumes | The clean and dirty tanks each hold 32 fl oz. | Clean-tank capacity is 2.36 L and recovery capacity is 1.3 L. | Check the clean and recovery capacities one at a time. |
| Cleaning format | It is a portable hose-based spot cleaner. | The upright cleaning path is 7.5 inches wide. | Working a spot with a hose and cleaning a room standing up are not the same job. |
| Preparation and tools | SmartMix meters compatible BISSELL portable-machine formula. | Included above-floor tools include a 4-inch self-cleaning stain tool and spraying crevice tool. | Metering formula automatically and choosing a nozzle each handle a different part of the routine. |
Trade-offs
Change of plan
Go with BISSELL Little Green Max Pet SmartMix. SmartMix works with the approved portable formula. There is no standing upright floorhead for whole-room work.
Go with BISSELL TurboClean PET. The supplied hose tools cover occasional above-floor work. With a full clean tank it starts at about 19.2 lb.
Decision guide
For localized sofa or stair spots and a lighter filled carrying load, pick Little Green Max Pet SmartMix. For room-sized carpet where a standing upright floorhead is more useful, pick TurboClean Pet 3948. Compatible formula, wet-cleanable materials and recovery-tank care are needed with both.
With two or three upstairs spots to treat, the estimated 10.3 lb for Little Green Max (body plus full clean tank) is substantially below TurboClean's roughly 19.2 lb. Go with the portable when carrying and precise hose work dominate. TurboClean's floorhead earns its extra size once the job spreads across a room. These estimates do not prove comfort for a particular user, and either machine gets heavier if recovered water stays in the tank during a move. The Max figure is 8.2 lb plus 32 fl oz of water, about 2.09 lb. The TurboClean figure is 14 lb plus 2.36 L of water, about 5.20 lb. Recovery tanks are assumed empty, and accessories are left out.
With TurboClean's 7.5-inch upright path, you clean carpet standing up, whereas the Max has you work through its handheld hose tool. That makes TurboClean the more practical candidate for a room-sized route and the Max the candidate for furniture edges or localized spills. The 1.3 L recovery tank on TurboClean is only about 55 percent of its 2.36 L clean tank, so don't count on a full clean-tank run without a stop to empty the recovery side. Actual recovered volume depends on use. 1.3 divided by 2.36 is approximately 0.55. That points to unequal tank volumes and says nothing about how many minutes or square feet can be cleaned before emptying.
SmartMix on the Max can take over the dosing step for its approved portable-machine formula, which helps when a quick spot job would otherwise mean measuring again and again. Don't stretch that convenience into permission for arbitrary concentrates, or into an assumption that upright-machine solution can be substituted. Pick the Max if this preparation step and its portable role fit the job. TurboClean's standing floorhead can still be the better reason to pick it for a room-sized carpet route. The exact Max product documents SmartMix and compatible portable formula. The evidence here does not establish the same automatic dosing feature for TurboClean, and no detergent-cost or cleaning-strength ratio is supported.
