Little Green HydroSteam vs Pet Pro Compared: Steam needs compatible stains, but Pet Pro carries lighter with more hose reach

Quick verdict

For oily or set stains on compatible surfaces, HydroSteam is the targeted choice. Pet Pro is easier to recommend when accidents keep happening, as it is lighter, has a longer hose and comes with dedicated hair and crevice tools.

What this page compares

Pet cleanup with higher capacity, or stain work with steam assistance.

This one comes down to steam and weight first, then to the limits of your own setup.

Day to day

How each one fits your routine

With equal clean tanks, the body-weight gap stays as it is

Clean water in each is 64 ounces, about 4.2 pounds before formula. Their listed body weights therefore become roughly 17.2 pounds for HydroSteam and 15.2 pounds for Pet Pro before recovery liquid. If you often carry the cleaner to car seats or upstairs furniture, Pet Pro keeps its approximate two-pound advantage and gives up no nominal clean capacity. Choose HydroSteam if its approved steam modes are useful enough to justify the heavier package.

Where this comes from

The same water load is added to the published 13- and 11-pound bodies in these estimates. They do not predict lifting comfort, and they do not advise carrying a full machine on stairs.

A fabric can allow extraction and still rule out steam

With three modes, HydroSteam has an additional heat-based option, but the care instructions of the furniture manufacturer must permit the chosen treatment. When the upholstery allows water extraction and forbids steam, use an approved non-steam process and do not buy for the steam feature. Pet Pro is a simpler fit when that is the whole intended job. If the material excludes water extraction, neither is established suitable.

Where this comes from

Whether steam is available and whether the surface is compatible are separate questions. No claim is made that every HydroSteam mode uses steam, and the upright 4123's stain chart is not carried over to this different portable 3618 model.
