Main trade-off
BISSELL Little Green
The short attachment hose requires moving the body around a sofa or vehicle.
Head-to-head
BISSELL Little Green vs Hoover CleanSlate Plus: Little Green holds more solution, CleanSlate switches cushions to seat seams
The short answer
Choose Little Green 1400B if you want more clean solution in a simple spot-cleaning machine. Choose Hoover CleanSlate Plus for its wide tool, crevice tool and hose-rinse attachment. The Hoover toolkit is especially useful when one session includes both broad cushions and narrow seat seams.
Before you choose
The reasoning and the trade-offs
Little Green adds one fifth more clean solution
Its 48-ounce tank holds 8 ounces more.
What this is based on
(48 − 40) ÷ 40 × 100 =20%. This does not predict a 20% longer cleaning session.
Main trade-off
Hoover CleanSlate Plus
Its 40-ounce clean tank can be used quickly with the seven-inch tool.

About this comparison
Compare Little Green 1400B and CleanSlate Plus FH14050 for sofa cushions, car seats, tank refills and cleaning the hose afterward.
Before you choose
How they fit your plans
The larger supply matters differently on a short carried job
Little Green's 48 ounces hold about 3.1 pounds of water, compared with about 2.6 pounds in CleanSlate's 40-ounce tank. For a single remote stair spot, filling to an appropriate marked level can matter more than maximum capacity. Choose Little Green when the extra supply is useful near one location. Choose CleanSlate if its tool shapes fit the job, without treating its smaller tank alone as proof of a lighter complete machine.
Facts behind this advice
48 and 40 fluid ounces correspond to 0.375 and 0.3125 US gallon. Body weights must also be compared on the same basis before ranking the loaded machines.
Both can rinse the hose with the right accessory
CleanSlate includes a hose-rinse process, and the current Little Green manufacturer list names HydroRinse even though seller contents vary. If cleaning the hose after a pet spot is important, verify that accessory in the exact Little Green box before choosing. Favor CleanSlate when its confirmed rinse setup and wide tool suit the job, or Little Green when its larger supply matters and its required accessory is confirmed.
Facts behind this advice
A rinse attachment addresses residue inside the hose. Both still need separate attention to the recovery tank and tools, so neither should be described as maintenance-free after a contaminated spot.

What matters in practice
The differences that matter
Little Green adds one fifth more clean solution
Its 48-ounce tank holds 8 ounces more.
How we reached this conclusion
(48 − 40) ÷ 40 × 100 =20%. This does not predict a 20% longer cleaning session.
CleanSlate's recovery tank is the smaller reservoir
The 23-ounce dirty tank is 57.5% of the 40-ounce clean tank.
How we reached this conclusion
23 ÷ 40 ×100 =57.5%. Recovery varies with fabric, application and extraction passes.
Hoover covers two differently shaped jobs
Its seven-inch and crevice tools suit broad cushions and tight seams.
How we reached this conclusion
The conclusion follows from the supplied tool shapes. It is not a measured stain-removal advantage.

What you give up
Every choice has a cost
If you choose BISSELL Little Green
- Tool packs vary. The current official 1400B page lists HydroRinse, so verify the Amazon carton contents.
If you choose Hoover CleanSlate Plus
- A roughly 4.5-foot hose offers less reach than the five-foot BISSELL Pet Pro.
What matters in practice
How to make the call
Tank capacity and tool coverage pull in opposite directions
Little Green holds 48 ounces of clean solution, compared with 40 ounces for CleanSlate. Hoover's seven-inch tool can cover broad fabric, but a wide tool also distributes solution across a bigger strip. The smaller tank is not automatically a problem for a few spots. It becomes more relevant when you plan to clean a whole sectional in one outing.
The dirty tank may end the run first
CleanSlate has a 23-ounce recovery tank, only 57.5% of its 40-ounce clean tank's nominal capacity. Recovery does not equal the amount sprayed because some moisture remains in the material. Even so, check the dirty tank instead of assuming one clean fill always means one uninterrupted session. Pre-wetted material can also add recovered liquid you did not spray.
Choose cleanup hardware you will use
Hoover includes a hose-rinse attachment plus separate wide and crevice tools. The current 1400B manufacturer list includes HydroRinse, although the exact seller bundle should be checked. After a pet accident, being able to flush the hose conveniently is worth considering, but it does not remove the need to wash tanks and tools. Neither portable head is an efficient substitute for an upright across whole rooms.
What this comparison cannot tell you
- Tool width does not establish relative suction or stain-removal performance.
- Tank ratios describe containers, not how much moisture remains in fabric.
