The catch
BISSELL Little Green
With such a short attachment hose, you end up repositioning the body around a sofa or vehicle.
Side by side
BISSELL Little Green vs Hoover CleanSlate Plus Compared: CleanSlate switches cushions to seat seams while Little Green holds more solution
Quick verdict
Little Green 1400B is the pick if you want more clean solution in a simple spot cleaner. Hoover CleanSlate Plus is the pick for its wide tool, crevice tool and hose-rinse attachment, and that toolkit is especially handy when one session covers both broad cushions and narrow seat seams.
Before you buy
Why, and what it costs you
Little Green carries one fifth more clean solution
The 48-ounce tank has room for 8 more ounces.
Where this comes from
(48 − 40) ÷ 40 × 100 =20%. Do not expect a 20% longer cleaning session from it.
The catch

The 40-ounce clean tank can go fast when you work with the seven-inch tool.

Day to day
How each one fits your routine
A larger supply plays out differently on a short job you carry the machine to
Little Green's 48 ounces come to about 3.1 pounds of water, against about 2.6 pounds in CleanSlate's 40-ounce tank. For one spot far up the stairs, filling to a sensible marked level can count for more than maximum capacity. Little Green is the choice when the extra supply helps at a single location. CleanSlate is the choice when its tool shapes suit the job, though a smaller tank alone does not prove the whole machine is lighter.
Where this comes from
48 and 40 fluid ounces work out to 0.375 and 0.3125 US gallon. Before you rank the machines with water in them, their body weights have to be compared on the same basis too.
With the right accessory, either one can rinse its hose
CleanSlate comes with a hose-rinse process. The manufacturer's current list for Little Green names HydroRinse, although what sellers include varies. If flushing the hose after a pet spot matters to you, confirm that accessory is in the exact Little Green box before you decide. CleanSlate is the better fit when its confirmed rinse setup and wide tool suit the job. Little Green is the better fit when the larger supply matters and its required accessory is confirmed.
Where this comes from
A rinse attachment deals with residue inside the hose. The recovery tank and the tools still need their own cleaning on both machines, so neither is maintenance-free after a contaminated spot.

In practice
Differences you will notice
Little Green carries one fifth more clean solution
The 48-ounce tank has room for 8 more ounces.
How we worked this out
(48 − 40) ÷ 40 × 100 =20%. Do not expect a 20% longer cleaning session from it.
CleanSlate's dirty tank is the smaller of the pair
At 23 ounces, the dirty tank is 57.5% the size of the 40-ounce clean tank.
How we worked this out
23 ÷ 40 ×100 =57.5%. Actual recovery differs by fabric, application and number of extraction passes.
Hoover handles two different shapes of job
The seven-inch tool and the crevice tool fit wide cushions and tight seams.
How we worked this out
This conclusion comes from the shapes of the tools in the box. It is not a measured edge in removing stains.

Trade-offs
What each pick costs you
With BISSELL Little Green
- The current official 1400B page lists HydroRinse, but tool packs differ, so confirm what comes in the Amazon carton.
With Hoover CleanSlate Plus
- Reach is shorter with the roughly 4.5-foot hose than with the five-foot BISSELL Pet Pro.
Decision guide
How to decide
If more clean solution in a simple spot-cleaning machine is the goal, go with Little Green 1400B. If you want the wide tool, the crevice tool and the hose-rinse attachment, go with Hoover CleanSlate Plus, whose toolkit pays off most when one session mixes broad cushions with narrow seat seams.
Tank size and tool coverage trade off against each other
CleanSlate holds 40 ounces of clean solution, while Little Green holds 48 ounces. The seven-inch tool on the Hoover can cover broad fabric, though a wide tool also spreads solution across a bigger strip. For a few spots, the smaller tank isn't automatically a problem. It matters more if you plan to clean a whole sectional in one outing.
The dirty tank might cut the job short
On CleanSlate, the recovery tank is 23 ounces, just 57.5% of the nominal capacity of its 40-ounce clean tank. What you recover is not the same as what you sprayed, because some moisture stays in the material. Still, keep an eye on the dirty tank rather than assuming one clean fill always means one uninterrupted session. Material that was already wet can also bring in recovered liquid you never sprayed.
Pick the cleanup hardware you'll use
A hose-rinse attachment comes with the Hoover, along with separate wide and crevice tools. The manufacturer's current 1400B list includes HydroRinse, but you should still check the exact seller bundle. Being able to flush the hose easily after a pet accident is worth weighing, but tanks and tools still have to be washed. Neither portable head can efficiently stand in for an upright across whole rooms.
What this page can’t tell you
- A wider tool tells you nothing about relative suction or stain-removal performance.
- Tank ratios describe the containers. They don't say how much moisture stays in the fabric.
