Main trade-off
BISSELL Little Green Mini
The narrow portable tool is not a whole-room upright floorhead
Head-to-head
Choose Little Green Mini for its documented seven-pound portable body and small spot jobs. Choose CleanSlate Plus for a wider cushion nozzle and a dedicated tight-space tool. A complete filled-weight comparison is not supported because this evidence does not establish CleanSlate's empty weight.
Before you choose
Little Green Mini's 7 lb body gives a clear starting point if the cleaner must move repeatedly between a car, closet and upstairs room. CleanSlate's 40 oz clean tank alone adds about 2.6 lb when full, but its verified empty-body weight is missing from this evidence, so a complete carrying-weight winner would be premature. Choose Mini for its known compact carry format, or CleanSlate when its wider tool set solves the main job. Carry first and fill at the destination when practical.
What this is based on
40 US fluid ounces is 1.183 L, adding about 2.61 lb of water. The calculation excludes formula, recovery liquid and accessories, and does not compare two complete filled machines.

Compare Little Green Mini 4075 and Hoover CleanSlate Plus for carrying, cushion-tool width, narrow seams and separate tank limits.
Choose a documented seven-pound portable for carrying or a wider stain nozzle and separate tight-space tool for larger furniture patches.
Winner by situation
Mini lists 7 lb. This evidence does not establish a comparable CleanSlate empty-body weight.
Mini's verified bundle has a 4-inch tool. CleanSlate includes a 7-inch WidePath nozzle.
CleanSlate documents TightSpot. Do not assume Mini includes an equivalent tool simply because other accessories are compatible.
Both apply cleaning liquid. The material restriction takes precedence over portability or tool width.

For a broad seat cushion, CleanSlate's 7-inch WidePath nozzle covers a wider strip per placement than Mini's documented 4-inch tool. CleanSlate also supplies TightSpot for narrow seams, making it the clearer candidate for mixed cushion-and-crevice work. Mini is useful for smaller isolated spots and simpler storage. Tool width does not predict cleaning speed or drying time because pass overlap, suction seal and fabric condition still matter. Both require attended wet extraction and compatible upholstery.
7 divided by 4 is 1.75 times the nominal tool width, not 75 percent faster cleaning. Confirm the exact 4075 bundle because compatible accessories shown on a parts page are not automatically included.
CleanSlate's 23 oz recovery tank is smaller than its 40 oz clean tank. For a large cushion or stair job, plan to check recovery capacity rather than assume a full clean-tank batch can always be extracted without emptying. Its smaller-batch fill marking is useful for isolated spots. Mini remains the compact alternative, but its tank volumes were not established here, so no relative refill-frequency claim is ready.
23 divided by 40 is 57.5 percent. This capacity relationship does not predict recovered volume or elapsed cleaning time.

Meaningful differences
| What changes | BISSELL Little Green Mini | Hoover CleanSlate Plus | Why it matters |
|---|---|---|---|
| Empty weight | BISSELL lists a 7 lb machine weight. | Not verified | Only Mini has a verified comparable body weight in this evidence. |
| Supplied stain tools | The exact 4075 catalog bundle includes a 4-inch stain tool and HydroRinse tool. | The tool set includes a 7-inch WidePath nozzle and a TightSpot tool. | Tool width changes the strip covered per placement, not proven cleaning speed. |
| Tank arrangement | Clean and dirty water use separate removable tank assemblies. | The CleanSlate platform has a 40 oz clean tank and a 23 oz recovery tank. | Separate clean and recovery tanks create independent fill limits. |
| Cord and hose | It uses an attached hose and a corded power supply. | The cord is 15 feet and the hose is 4.5 feet. | Check reach from a stable parking position. |
What you give up
Recommendation switch
Choose BISSELL Little Green Mini. Use a compact portable for localized spots. The narrow portable tool is not a whole-room upright floorhead.
Choose Hoover CleanSlate Plus. Use the dedicated TightSpot attachment for narrow gaps. A complete filled-weight comparison remains unverified.
