BISSELL Little Green HydroSteam 3618 vs Little Green 1400B, Compared: Steam comes to an estimated full-clean-tank load of 17.2 lb versus 12.8 lb

Quick verdict

Little Green 1400B is the better choice if repeated carrying matters more to you than steam. With a full clean tank, its estimated load is about 12.8 lb including the body, against 17.2 lb for HydroSteam 3618. The 3618 is the better choice if its steam modes are permitted on the surfaces you intend to clean and are worth the extra load.

Before you buy

Why, and what it costs you

Filling the clean tank widens the carrying gap

When the cleaner has to go upstairs filled, the 3618 starts at around 17.2 lb with its 64 oz clean tank full, while the 1400B with 48 oz starts at about 12.8 lb. That makes it roughly 4.4 lb heavier, before accessories or recovered water. Pick the 1400B if repeated lifting is your main constraint. Pick the 3618 if a compatible steam job justifies the extra body and water weight. Either load drops when you carry the machine empty and fill it upstairs.

Where this comes from

Taking water at 1 kg per liter, 64 fl oz adds 4.17 lb and 48 fl oz adds 3.13 lb. The totals build on published empty weights of 13 and 9.65 lb, with the recovery tanks empty.

In practice

Differences you will notice

Filling the clean tank widens the carrying gap

When the cleaner has to go upstairs filled, the 3618 starts at around 17.2 lb with its 64 oz clean tank full, while the 1400B with 48 oz starts at about 12.8 lb. That makes it roughly 4.4 lb heavier, before accessories or recovered water. Pick the 1400B if repeated lifting is your main constraint. Pick the 3618 if a compatible steam job justifies the extra body and water weight. Either load drops when you carry the machine empty and fill it upstairs.

How we worked this out

Taking water at 1 kg per liter, 64 fl oz adds 4.17 lb and 48 fl oz adds 3.13 lb. The totals build on published empty weights of 13 and 9.65 lb, with the recovery tanks empty.

Steam is only worth having on a surface that allows it

SteamWash, Wash and Steam modes give the 3618 an extra treatment choice, whereas the 1400B sprays, scrubs and extracts with no steam. If your regular job is upholstery that tolerates water but not heat, the lighter 1400B is the straightforward pick. The 3618 stays useful on other surfaces where both its manual and the material's care instructions allow steam. Do not carry urine-mode advice over from the separate 4123 upright just because both products carry the HydroSteam name.

How we worked this out

This recommendation is based on which modes exist and what the material permits. Nothing here says steam is always better for pet stains, that either machine sanitizes the fabric, or that the upright and the portable follow identical instructions.

A bigger clean-water supply doesn't promise fewer stops

At 64 oz of clean liquid, the 3618 holds one-third more than the 1400B's 48 oz. That can mean less refilling early in a larger portable job, but the 3618 also has its own 51 oz recovery limit. Go for the extra capacity when it is worth carrying, and keep an eye on the recovery tank. With no matched measurements of liquid use and recovery, neither cleaner can be promised a set number of stairs per fill.

How we worked this out

64 divided by 48 comes to 1.33. The 51 oz recovery tank is about 80 percent of the 3618 clean tank, which makes the two capacities separate constraints.

Decision guide

How to decide

When repeated carrying outweighs the appeal of steam, choose Little Green 1400B, whose estimated body-plus-full-clean-tank load is about 12.8 lb against 17.2 lb for HydroSteam 3618. If steam modes are permitted for the intended surfaces and justify the extra load, 3618 is the right call.

01

Filling the clean tank widens the carrying gap

Say the cleaner has to go upstairs filled. The 3618 then comes in around 17.2 lb with its 64 oz clean tank full, against about 12.8 lb for the 1400B with 48 oz. That is roughly 4.4 lb more, before accessories or recovered water. When repeated lifting is the main constraint, go with the 1400B. When a compatible steam job justifies the extra body and water weight, go with the 3618. Either load drops if you carry the machine empty and fill it upstairs. At 1 kg per liter of water, 64 fl oz adds 4.17 lb and 48 fl oz adds 3.13 lb. The totals use published empty weights of 13 and 9.65 lb, with the recovery tanks empty.

02

Steam is only worth having on a surface that allows it

SteamWash, Wash and Steam modes give the 3618 an additional treatment choice, whereas the 1400B sprays, scrubs and extracts without steam. If your regular job is water-compatible upholstery that does not allow heat, the lighter 1400B is the straightforward choice. The 3618 stays useful on other surfaces, where its manual and the material's care instructions allow steam. Don't carry over urine-mode advice from the separate 4123 upright just because both products carry the HydroSteam name. The recommendation rests on which modes are available and what the material permits. It does not claim that steam is always better for pet stains, that either machine sanitizes the fabric, or that the upright and the portable share identical instructions.

03

A bigger clean-water supply doesn't promise fewer stops

At 64 oz of clean liquid, the 3618 holds one-third more than the 1400B's 48 oz. That can cut down the initial refilling on a larger portable job, but the 3618 also has a separate 51 oz recovery limit. Pick its capacity if it is useful enough to be worth carrying, and keep checking the recovery tank. Without matched measurements of liquid use and recovery, neither cleaner can be promised to do a specific number of stairs per fill. 64 divided by 48 is 1.33. The 51 oz recovery tank is about 80 percent of the 3618 clean tank, which makes the two capacities distinct constraints.

Check these before you buy

  • Find the manual for the exact portable 3618 and the fabric's care instructions that match the stain and mode you plan to use.
  • Pick up loose dry debris separately, and let the extracted material dry completely before use.

What this page can’t tell you

  • This recommendation is based on which modes exist and what the material permits. Nothing here says steam is always better for pet stains, that either machine sanitizes the fabric, or that the upright and the portable follow identical instructions.
