The catch
BISSELL Little Green Mini
The narrow tool on a portable does not replace a whole-room upright floorhead
Side by side
Little Green Mini is the choice for its documented seven-pound portable body and small spot jobs. CleanSlate Plus is the choice for a wider cushion nozzle and a dedicated tight-space tool. Because the evidence here does not establish CleanSlate's empty weight, a complete filled-weight comparison isn't supported.
Before you buy
If the cleaner has to keep moving between a car, a closet and an upstairs room, Little Green Mini's 7 lb body is a clear place to start. A full 40 oz clean tank adds about 2.6 lb to CleanSlate by itself, but this evidence has no verified empty-body weight for it, so naming a winner on total carrying weight would be premature. Pick Mini for its known compact carry format, or CleanSlate if its wider tool set handles your main job. Where practical, carry the machine first and fill it at the destination.
Where this comes from
40 US fluid ounces comes to 1.183 L, which adds about 2.61 lb of water. The calculation leaves out formula, recovery liquid and accessories, and it is not a comparison of two complete filled machines.

Little Green Mini 4075 against Hoover CleanSlate Plus on carrying, cushion-tool width, narrow seams and separate tank limits.
For carrying, pick the portable documented at seven pounds. For larger furniture patches, pick the one with a wider stain nozzle and a separate tight-space tool.
Which one fits
Mini is listed at 7 lb. Nothing in this evidence gives a comparable empty-body weight for CleanSlate.
A 4-inch tool is in Mini's verified bundle. CleanSlate comes with a 7-inch WidePath nozzle.
TightSpot is documented for CleanSlate. Do not assume Mini has an equivalent tool just because other accessories are compatible.
Each applies cleaning liquid. The restriction on the material outranks portability and tool width.
In practice
If the cleaner has to keep moving between a car, a closet and an upstairs room, Little Green Mini's 7 lb body is a clear place to start. A full 40 oz clean tank adds about 2.6 lb to CleanSlate by itself, but this evidence has no verified empty-body weight for it, so naming a winner on total carrying weight would be premature. Pick Mini for its known compact carry format, or CleanSlate if its wider tool set handles your main job. Where practical, carry the machine first and fill it at the destination.
40 US fluid ounces comes to 1.183 L, which adds about 2.61 lb of water. The calculation leaves out formula, recovery liquid and accessories, and it is not a comparison of two complete filled machines.
On a broad seat cushion, CleanSlate's 7-inch WidePath nozzle covers a wider strip each time you set it down than Mini's documented 4-inch tool does. CleanSlate also comes with TightSpot for narrow seams, which makes it the clearer candidate when the work mixes cushions and crevices. Mini is handy for smaller isolated spots and easier storage. Tool width does not predict cleaning speed or drying time, since pass overlap, suction seal and fabric condition still matter. Both need you present for wet extraction, and both need compatible upholstery.
The nominal tool width is 1.75 times larger (7 divided by 4), which does not mean 75 percent faster cleaning. The exact 4075 bundle needs confirming, since compatible accessories on a parts page aren't automatically included.
The recovery tank on CleanSlate holds 23 oz, less than its 40 oz clean tank. On a large cushion or a stair job, plan on checking the recovery tank and do not assume a full clean-tank batch can always be extracted without emptying. Its smaller-batch fill marking helps with isolated spots. Mini is still the compact alternative, but its tank volumes were not established here, so there is no basis yet for saying which one needs refilling more often.
23 divided by 40 comes to 57.5 percent. That ratio of capacities says nothing about how much liquid is recovered or how long cleaning takes.

BISSELL, 4075
Quick spots, car footwells and very small storage spaces are what this seven-pound portable is designed for.

Hoover, FH14050
This portable spot cleaner pairs a seven-inch wide tool with a narrow crevice tool.
Spec by spec
| Spec | BISSELL Little Green Mini | Hoover CleanSlate Plus | In practice |
|---|---|---|---|
| Empty weight | BISSELL lists a 7 lb machine weight. | Not verified | In this evidence, Mini is the only one with a verified, comparable body weight. |
| 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. | A wider tool covers a bigger strip per placement, which is not the same as 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. | Each of the clean and recovery tanks has its own fill limit. |
| 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. | Judge reach from a steady parked position. |
Trade-offs
Change of plan
Go with BISSELL Little Green Mini. A compact portable is for localized spots. Its narrow tool cannot stand in for a whole-room upright floorhead.
Go with Hoover CleanSlate Plus. For narrow gaps, use the dedicated TightSpot attachment. No complete comparison of filled weights has been verified.
Decision guide
For its documented seven-pound portable body and small spot jobs, pick Little Green Mini. For a wider cushion nozzle and a dedicated tight-space tool, pick CleanSlate Plus. A complete filled-weight comparison isn't supported here, because this evidence does not establish CleanSlate's empty weight.
If the cleaner has to move over and over between a car, a closet and an upstairs room, the 7 lb body of Little Green Mini is a clear starting point. On the CleanSlate, the 40 oz clean tank by itself adds about 2.6 lb when full, but this evidence is missing a verified empty-body weight, so naming a complete carrying-weight winner would be premature. Pick Mini for its known compact carry format, or CleanSlate if its wider tool set solves the main job. Where practical, carry the machine first and fill it at the destination. 40 US fluid ounces is 1.183 L, which adds about 2.61 lb of water. The calculation leaves out formula, recovery liquid and accessories, and it does not compare two complete filled machines.
On a broad seat cushion, the 7-inch WidePath nozzle on CleanSlate covers a wider strip per placement than the documented 4-inch tool on Mini. CleanSlate also comes with TightSpot for narrow seams, which makes it the clearer candidate for mixed cushion-and-crevice work. Mini is handy for smaller isolated spots and simpler storage. Tool width can't predict cleaning speed or drying time, since pass overlap, suction seal and fabric condition still matter. Either machine needs 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.
The recovery tank on CleanSlate holds 23 oz, less than its 40 oz clean tank. On a large cushion or a stair job, check recovery capacity instead of assuming a full clean-tank batch can always be extracted without emptying. The smaller-batch fill marking helps with isolated spots. Mini stays the compact alternative, but its tank volumes were not established here, so there is no relative refill-frequency claim to make yet. 23 divided by 40 is 57.5 percent. That capacity relationship says nothing about recovered volume or elapsed cleaning time.
