The catch
BISSELL Little Green HydroSteam
It weighs about 13 pounds, which is clearly more than the Little Green Mini.
Side by side
BISSELL Little Green HydroSteam vs Shark StainStriker Compared: Different fabric-compatibility checks apply to steam and oxygen formulas
Quick verdict
Little Green HydroSteam is the right call if you want steam for compatible surfaces in addition to normal extraction. Shark StainStriker fits frequent spot and odor work, particularly if you like its two-formula tool. Look at the fabric before anything else. Heat and oxygen-based cleaners are different treatments, and neither is right for every material.
Before you buy
Why, and what it costs you
Steam brings one more compatibility call

Where this comes from
BISSELL offers SteamWash, Wash and Steam modes. The Shark PX201 has no steam function.
The catch
Shark StainStriker Portable
Keeping the dual-formula routine going means stocking two compatible products.

What this page compares
Stain type, fabric compatibility, formula supplies and finishing the job are the points of comparison between Little Green HydroSteam 3618 and Shark StainStrikerPX201.
Day to day
How each one fits your routine
Settle on an approved treatment first, then think about the extra feature
The portable HydroSteam 3618 has both steam and non-steam modes. StainStriker works through its two-part cleaning chemistry and has no steam function. When the furniture allows water extraction but not steam, compare only the non-steam processes that are approved, and do not write off every HydroSteam mode or count steam as a plus. When a compatible surface is why you want steam, HydroSteam gives you that extra option. A stain being labeled pet-related does not make either one suitable on its own.
Where this comes from
Material approval and the mode you pick decide this. The stain chart for the separate upright 4123 is not applied to the portable 3618, and neither process is claimed to sanitize.
Finishing with water alone means dealing with Shark's second reservoir
When the approved cleaning process ends in a water-only rinse, the PX201 guide has you fill the main tank with water and empty or remove OXY as directed. Adding water while the second supply stays active is a different setup. Shark works if you can accept that two-reservoir routine. If switching modes often is your main worry, look at HydroSteam's instructions for the appropriate wash mode.
Where this comes from
This limits how you prepare. It does not say a rinse is always needed. The material instructions and the manufacturer's formula directions decide whether another wet pass is appropriate.

How we worked this out
BISSELL offers SteamWash, Wash and Steam modes. The Shark PX201 has no steam function.
BISSELL's recovery tank holds roughly four fifths as much as its clean tank
At 51 ounces, the reservoir comes to 79.7% of 64 ounces.
How we worked this out
51 ÷64 ×100 =79.7%. The volume recovered depends on moisture already in the fabric and on extraction.
Shark needs two formula supplies on hand
If either approved component runs out, the treatment cannot go as intended.
How we worked this out
The PX201 tool uses Deep Clean Pro and OXY Multiplier together. The conclusion is about planning your supplies.

Trade-offs
What each pick costs you
With BISSELL Little Green HydroSteam
- Check the fabric before using steam, and take care near finishes and adhesives.
With Shark StainStriker Portable
- Bundles differ from seller to seller. Look at exactly which rinse and pet tools you get, rather than assuming every tool in the family manual comes along.
Decision guide
How to decide
When you need a steam option for compatible surfaces on top of normal extraction, choose Little Green HydroSteam. For frequent spot and odor work with a two-formula tool you like, choose Shark StainStriker. The fabric comes first. Heat and oxygen-based cleaners are different treatments, and neither suits all materials.
Let the material answer the first question
Find the item's cleaning instructions before you weigh claims about difficult stains. Upholstery that can take water is not automatically safe for steam, and a surface approved for one cleaner might not tolerate the formula of the other. Since Little Green HydroSteam has more than one mode, owning a steam machine doesn't mean steam is right for every job. Whatever treatment is permitted, try it in a hidden area first.
Behind a two-tank description sit two different ideas
On the BISSELL, a 64-ounce clean tank is kept apart from a 51-ounce recovery tank. Shark's selling point in this matchup is two formulas that combine while cleaning. Keeping clean and dirty water apart is not the same feature as activating two formulas. With the Shark, plan on keeping both approved formulas in stock. With the BISSELL, plan on taking time to select the right mode for each surface.
A steam mode does not make it a whole-house steam cleaner
These are portable spot machines, and both have small hand tools. Around sofas or vehicle seats, you still have to position BISSELL's roughly 4.8-foot hose and 13-pound empty body. The dirty reservoir on it is smaller than the clean tank, which means a large damp area can call for emptying before the solution runs out. Either works for localized jobs. For broad carpet cleaning, reach for an upright instead.
What this page can’t tell you
- No matched test here shows that one of them removes more of every stain.
- Having a steam mode does not guarantee sanitization.
