Quick verdict
Choose the original Little Green when ordinary spray-and-extraction cleaning covers your approved surfaces. Consider HydroSteam when its additional modes match a real recurring task and the material permits them. Steam capability is not permission to treat every sofa, rug or finish.

Little Green HydroSteam cleaners
Little Green is a product family, not one specification shared by every green portable cleaner. This comparison uses the original 1400B as the basic reference and the 3618 HydroSteam family, including Canada’s 3618C, as the upgrade. Match the actual model and tools before comparing prices.
Compare the task, not the color
| Decision | Original Little Green | Little Green HydroSteam |
|---|---|---|
| Main workflow | Spray, scrub and extract on approved materials | Additional selectable cleaning modes |
| Reason to choose | Basic spot-cleaning needs | Specific tasks benefiting from supported steam use |
| Important check | Material and formula compatibility | Material, formula and mode compatibility |
When the original machine is enough
If your need is an occasional spill on a surface approved for extraction cleaning, the simpler machine may cover it. BISSELL describes the original process as applying water and the appropriate formula, working the area and recovering the liquid. It is not the same as a dry vacuum routine.
Compare the tool width, hose reach and tank access against your usual jobs. A machine that stores neatly can still be awkward on stairs or around a large sofa. Check the exact bundle: included tools and trial formulas may vary between sellers and countries.
When HydroSteam makes sense
BISSELL’s Canadian HydroSteam page lists SteamWash, Steam and Wash modes for different intended tasks. That flexibility can be useful when you have several appropriate surfaces and will choose the right mode. It adds less value if the only task you need uses ordinary washing.
We have not compared stain removal, drying time or the manufacturer’s performance claims. Do not assume the upgrade removes every stain or makes a delicate material suitable for steam. The surface manufacturer’s care instructions and BISSELL’s current manual should agree before use.
Check the material before buying either
Identify the upholstery or rug’s care requirements first. A familiar-looking woven cover can contain backing, dyes or construction that limits water or heat. Test only as permitted by the instructions. If the intended material needs professional treatment or another method, buying a portable extractor may not solve the problem.
Also plan the drying conditions. Recovering liquid is part of the process, but the fabric still needs the appropriate time and ventilation. Avoid soaking a cushion or judging the task complete from the visible surface alone.
Maintenance and storage are real costs
Allow access to rinse and dry tanks, tools and the hose as the manual directs. A cleaning machine that is inconvenient to empty can become an unused cupboard item. Include the suitable formula, replacement parts and any accessories needed for your main task in the total cost.
Who should upgrade or skip?
Choose the original when its supported method covers the job. Pay for HydroSteam when a documented extra mode is useful often enough to justify it. Keep an existing working extractor when it already handles the approved surfaces. Skip both if you need whole-room carpet cleaning or another task outside the selected model’s intended role.
