Side by side
BISSELL Little Green Pet Pro vs Hoover CleanSlate, Compared: CleanSlate widens cushion passes and Pet Pro holds more liquid
Quick verdict
Little Green Pet Pro is the choice if you want larger tanks and a longer hose. CleanSlate is for broad cushion work, with its seven-inch tool and smaller liquid load.
Before you buy
Why, and what it costs you
Put tank capacities in the same units
Clean-liquid capacity is 0.5 US gallon for Little Green Pet Pro and 0.31 for CleanSlate Plus. The gap between them is 24 fluid ounces, before recovery-tank limits come into play.
Where this comes from
128 US fluid ounces =1 US gallon. The capacities on record are 64 and 40 fl oz. Converting puts tank volume on one scale and says nothing about cleaning coverage.
The catch
Hoover CleanSlate Plus
The 40-ounce clean tank can go fast when you work with the seven-inch tool.

A wide tool suits your flat cushions
On a flat cushion, the seven-inch WidePath tool covers a broader strip than a small detail tool does. Tight curves and seams might still call for the crevice attachment.

Look at the whole setup
The recovery side may need emptying sooner. When the dirty tank needs attention depends on foam, moisture already in the material and the fill line.

How we worked this out
128 US fluid ounces =1 US gallon. The capacities on record are 64 and 40 fl oz. Converting puts tank volume on one scale and says nothing about cleaning coverage.

How we worked this out
Approximate water mass = clean capacity in US gallons ×8.34 lb/gal. Inputs 64/128 and 40/128 gallons. The real total shifts with formula concentration, leftover dirty water and tools.

Spec by spec
Where they really differ
| Spec | BISSELL Little Green Pet Pro | Hoover CleanSlate Plus | In practice |
|---|---|---|---|
| Machine type | Portable spot cleaner | Portable spot cleaner | Using a spot cleaner in place of a whole-room upright is not efficient. |
| Nominal clean tank | 64 US fl oz | 40 US fl oz | Capacity does not promise area covered. |
| Empty weight | 11 lb | Not established here | Weight goes up with water, tools and solution. |
| Hose | 5 ft | 4.5 ft | Look at exactly what the bundle contains, and at any model documentation that disagrees. |
| Power cord | 15 ft | 15 ft | Usable reach depends on outlet position. |
| Cleaning system | Manual formula mixing, pet and crevice tools | Seven-inch WidePath and crevice tools | A feature list cannot name a winner without a matched cleaning test. |
Trade-offs

With BISSELL Little Green Pet Pro

Decision guide
How to decide
For larger tanks and a longer hose, choose Little Green Pet Pro. For broad cushion work with a seven-inch tool and a smaller liquid load, choose CleanSlate.
BISSELL holds more liquid in both tanks
Pet Pro's capacity is 64 ounces clean and 48 dirty, against 40 and 23 on CleanSlate. Depending on extraction and foam, the larger recovery tank may mean fewer stops to empty it.
Tool width is what Hoover has going for it
On a flat cushion, the seven-inch WidePath tool covers a broader strip than a small detail tool does. Tight curves and seams might still call for the crevice attachment.
A big clean tank doesn't delay every stop
The recovery side may need emptying sooner. When the dirty tank needs attention depends on foam, moisture already in the material and the fill line.
