Best Carpet Cleaner For Stairs: Full Buyers Guide


For the longest of times, my image of staircases was gilded banisters and Cinderella. Until I got two kittens. There’s something romance-killing about getting gritty with stair-stain. And trying to tool up brings about a puzzling portfolio of machines.

There are no purpose-built stair carpet cleaners, so choose from the categories of general carpet cleaners. These differ by cleaning method, portability, functionality, size, market segment, and price. By considering the context of application, these categories provide a handy stair carpet cleaner.

We’ll look at the peculiar problem that stair carpets provide, how to prep them for cleaning, and how to navigate the types of machines to find one that fits the context in which you clean.

How To Find The Best Carpet Cleaner

Reading this guide is a good start. After you’ve got the hang of  the process and technicalities of carpet cleaning and reviewed the models we introduce, you may:

  • Head straight for the checkout.
  • Browse similar models to the one that takes your fancy.
  • Filter our list of picks for models that are available where you live.
  • Dig a little deeper into the user reviews.

Either way, start with a clear understanding of how and to what end you want to use your carpet cleaner. This is the single biggest determinant of which machine to settle with.

Why Bother With Cleaning Stair Carpets?

They looked so lovely on installation. And if you squint the right way, your stairwell carpets still look great. Why not leave well alone?

Why Clean?

Asking the obvious reveals that:

  • Looks matter: Color-fastness of carpets is compromised by dust.
  • Health matters: The concentration of carpet bacteria per square quickly surpasses that of a toilet seat.

The considerations point to the importance of picking a cleaner that roots out deeply ingrained dirt and leaves carpets looking good well after the moisture has dried.

Why Buy?

Hiring professional carpet cleaning services or renting equipment is an option in many cases. However, for stairs, professional cleaning equipment is generally unwieldy. Rental equipment tilts towards the professional end.

Most home users will find that consideration of frequency seal the case for buying your own carpet cleaner.

Why Focus On Stairs?

Stairs have the following challenges:

  • They have small contiguous surface areas.
  • Half of the surface area is vertical facing.
  • They have many corners.
  • They require equipment to be lifted up and down.

They place constraints on the sort of machine that is fit for purpose.

Carpet Cleaning Methods

Understanding the main carpet cleaning methods will help you understand the specifications of the machines you’re considering. These methods are differentiated by the physics of how they extract embedded dirt.

Method1: Shampooing

The oldest method, this is done by dispersing a shampoo solution over the area to be cleaned. The solution is brushed into the carpet, where its chemicals catalyze the breaking up of dirt. 

A second water tank extracts the dirtied shampoo solution from the carpet.

The key problem in this method is the lack of an actual rinse cycle, which leaves unextracted shampoo in the carpet. This accrual of this over time dampens the base and spoils the carpet. 

Method2: Hot Water Extraction

This works on the same principle as shampooing. The difference is that instead of friction (though vigorous brushing), heat is used to soften, denature and dislodge the embedded grime. An advantage is that the carpet fibers are less prone to damage through friction.

HWE is sometimes called “steam cleaning,” even though the steam is inoperative and incidental to the heat. 

Method3: Dry Carpet Cleaning

This avoids water by targeting the oil in grime. It is this oil that makes the dirt bind, and dissolving it frees the embedded dirt to be vacuumed out of the carpet. After an initial dry vacuum, dry cleaning solution is applied to break down the oil. Thereafter cotton pads are attached to a rotor at the bottom of the carpet cleaner.

The rotational action lifts the oil-free dirt out of the carpet, binding with the detachable pads, which are disposed of after use.

Method4: Encapsulation

This takes dry cleaning a step further. A synthetic agent is applied to the surface area, acting on the oil and grime similar to shampoos and dry cleaning agents. The difference is that it dries to form a crystal powder. The crystals trap (“encapsulate”) the dislodged dirt, leaving a mass that can be vacuumed away.

Encapsulation is an environmentally friendly technology that saves water.

Method5: Bonnet Cleaning

Bonneting is a surface cleaning technique. It uses a padded machine – as in the last step of dry cleaning – but instead of preparing the area, the clean is done in a single step.

This works in areas like hotel lobbies where the frequency of carpet grooming means you can forego a deep clean. At the same time, the convenience of a single step limits cleaning time, making a high-traffic area inaccessible for the smallest possible period.

Before You Clean Stair Carpets

Application of the carpet cleaner is not your first step. Be sure to carry out the following preparatory procedures first.

Vacuum Cleaning

A preparatory sweep and vacuum remove dirt and particles that are not so deeply engrained and embedded that they need the technology of a special cleaning machine. Failure to do this risks driving surface dirt deeper during the clean and creating a bigger workload for the carpet cleaning machine.

Carpet Stain Removal

Discreet high-visibility stains like wine and animal waste should be treated in isolation before applying a general do-over. Precleaning these high-intensity smears increases the likelihood of an even finish.

Stain-removal agents (natural or synthetic) should be chosen to match the composition of the stain at hand.

Deep Cleaning Carpets

Be sure to deep clean your carpets on a regular basis. This will be punctuated with more frequent surface cleans. Failure to do the deep clean will leave an accumulating residue of embedded grime. Over time this will foil the efforts of your maintenance cleans.

Types of Carpet Cleaner

We consider the various types of carpet cleaner. Machines are marketed on this basis, and understanding what each category attempts to do is helpful in getting to grips with the design of specific carpet cleaners.

Stairwell Carpet Cleaners

These don’t exist. What remains is to consider a cleaner from one of the remaining types. Ask yourself these questions:

  1. What proportion of my carpet is on the stairs?
  2. In the light of 1. should I get a dedicated stair cleaner or one cleaner for all the carpet?
  3. How small are the spaces to be cleaned? Are there carpeted areas in the nooks around the stairwell?
  4. Do the stairs attract or exclude certain traffic (e.g., kids and pets)?
  5. How tall are the stairs? This has implications for the maneuverability of the machine sought.
  6. How frequently does the stairwell need cleaning? This has implications for the type of machine chosen.

These contextual questions are key to making the correct decision.

Domestic Carpet Cleaners

Carpet cleaners built for the home are small and compact. This ensures that they can access small places and be stored in home-sized storage spaces. They are maneuverable and can be operated with minimal exertion of energy and no requirement of professional skill.

These machines are lightweight and inexpensive. The tradeoff for all these plusses is that the machines are less powerful than their commercial equivalent, and the area to be cleaned may require preparation.

Commercial Carpet Cleaners

Commercial carpet cleaners target areas with more foot traffic. This would include schools, offices, waiting rooms, and reception areas. These machines are more robust than their domestic peers as they provide deeper cleaning. This deeper cleaning is needed for the volume of dirt that builds with the heavy use.

They are more durable and capable of professionally finished cleans. Their deep cleaning power targets deeply embedded grime, requiring less preparation than their domestic equivalents.

Industrial Carpet Cleaners

This is the most specialized class of carpet cleaners. They are designed for use by professional carpet cleaners, whose requirements include:

  • Long duration: As they serve several clients, the machines need to be in use every day for hours at a time.
  • Efficiency: The machines must remove large amounts of deeply compacted grime in a short space with little to no.
  • Professional capacity: Their owners have ample storage space and dedicated employees. There is no requirement to build compactness or ease-of-use in the design.

These machines are more expensive than the other two classes but indispensable for professional cleaners.
