Caster Wheels vs Driven Wheels in Pool Cleaners

What the two wheel words mean on a listing

Pool cleaner listings describe how a cleaner moves across the pool floor with wheel words. Two of those words appear often: caster wheels and driven wheels. Caster wheels are the free-spinning kind. They are mounted to the body and turn to follow the direction the cleaner takes. Driven wheels are connected to the drive system. They are powered to roll the cleaner forward or backward.

A listing title may say "caster wheels", "driven wheels", "two-wheel drive" or "four-wheel drive". These are stated details of the model. The maker's page holds the longer description of the drive system, the wheel material and how the cleaner turns. Read the listing for the word, then read the maker's page for the design.

The wheel words join other move-related words on a listing, such as "wall climbing", "swivel", "tracks" and "tires". A robot with driven wheels may still name track or tire material in the bullet list. Buyers who compare listings should read all of these as one set of stated details rather than letting one wheel word carry the whole decision.

Caster wheels as a listing word

When a listing names caster wheels, it tells a buyer that the cleaner has free-spinning wheels rather than a powered set. Caster wheels follow the direction of the frame. They do not pull the cleaner. A robotic cleaner with caster wheels still carries its drive motors elsewhere in the body.

A listing may say "caster wheels" in the title or in the bullet list. The absence of the words does not mean the cleaner has no caster wheels. Many listings name only the features the seller chose to highlight. Read the full listing and the maker's page to see the wheel configuration.

Caster wheels appear on many robotic models and on some suction-side models. A suction-side listing may say "caster wheels" to name the wheel design. The word does not state how many caster wheels the model has.

Driven wheels and drive wording

Driven wheels are the wheels that move the cleaner. A listing may say "driven wheels", "dual drive", "two-wheel drive" or "four-wheel drive". Each of these words describes the same idea: the wheels are connected to motors and roll the cleaner across the floor.

Driven wheels are often the larger wheels on a cleaner. They carry the body and provide the forward motion. On a listing, the drive wording appears next to the cleaner type: robotic models carry their own motors, while suction-side models roll with the water flow from the pool pump.

Drive wording sometimes appears as "traction wheels" or "drive wheels". These are the same idea in different words. The maker's page states the number of wheels and whether the wheel material is listed for the model.

Steering and wall grip as separate listing terms

A caster wheel or driven wheel word does not, by itself, state how well the cleaner steers or climbs. Steering is described by other listing words: turn radius, swivel, navigation. Wall grip is described by a separate claim: "wall climbing" or "climbs walls" in the title. Those are claims of their own.

Wall climbing is the maker's claim. The wheel type is one component of the design, but the listing does not spell out how the wheels and the drive system work together on a wall. To understand the design, read the maker's page. A separate article explains the wall climbing angle as a listing term.

Steering words such as "turn radius" and "swivel" describe how the cleaner changes direction. A swivel word on the floating cable or on the body is separate from wheel words. The listing states these as its own details, and the maker's page describes the turning behavior.

Which cleaner type uses which wheel word

Robotic cleaners, suction-side cleaners and pressure-side cleaners each move differently, and their listings name wheels differently. A cordless robot may list caster wheels or driven wheels because it carries its own motors. A suction-side cleaner is driven by water flow and often lists a wheel or tire design instead of a drive system.

A title that names a wheel type is a feature word. It does not replace the type word. Read the type word first: robotic, suction-side, pressure-side. Then read the wheel word as a detail of that type. The suction-side guide and the general pool cleaner guide group cleaners by type and stated details.

A holiday home buyer or a first-time pool owner may not need to compare wheel words at all. The first question is the cleaner type: robotic, suction-side or pressure-side. Wheel wording becomes useful when two listings of the same type make different drive claims.

Comparing listings that name wheels differently

When two listings make different wheel claims, compare them by the stated details and by the maker's pages. One listing may say "driven wheels", the other may say nothing about wheels. The maker's page for each model tells you the number of wheels, the drive system and whether the wheels are free-spinning or powered.

The site's guides group cleaners by stated details. Buyers can use the wall climbing guide to find models whose listings carry a wall climbing claim, and the inground pool guide to compare drive wording among robotic picks.

The site's guides list picks by stated details. They do not place a ranking value on wheel types. Each pick shows the listing words, and the buyer reads the maker's page for the drive description.

What to pick for your situation

Questions

What is a caster wheel on a pool cleaner?

A caster wheel is a free-spinning wheel mounted to the cleaner body. It follows the direction of the frame and does not pull the cleaner. A listing that says "caster wheels" states that the cleaner uses this kind of wheel.

What is a driven wheel on a pool cleaner?

A driven wheel is a wheel connected to the cleaner's drive system. It rolls forward or backward and carries the cleaner. Listings may say "driven wheels", "dual drive", "two-wheel drive" or "four-wheel drive".

Does a driven wheel mean the cleaner climbs walls?

No. Wall climbing is a separate claim on a listing. A driven wheel is one part of the drive design, but the listing does not state how the wheels behave on a wall. Read the wall climbing claim and the wall climbing guide for models whose listings carry it.

Which is better, caster wheels or driven wheels?

The site does not rank wheel types. The listing states the wheel type, and the maker's page describes the drive design. Compare stated details and match the cleaner type to your pool.

How do you know which wheel type a cleaner has?

Read the listing for a wheel word, and read the maker's page for the drive description. A listing may name caster wheels or driven wheels, or may leave the wheel type unstated.
