Quick verdict
Four 2 1/2 by 3/4 inch caster wheels that bolt onto a pressure washer surface cleaner, a water broom or an undercarriage cleaner, replacing the wheels that have worn flat, lost a bearing or snapped off so the housing drags on the concrete and leaves swirl marks. A surface cleaner rides on its wheels at a set height above the slab; wheels that are worn or missing drop the nozzle bar, scour the surface and wear the spray bar. Four fresh casters restore the height and the glide, for less than a new cleaner.
Strengths
- Restores a surface cleaner that drags or scours
- Fits most surface cleaners, water brooms and undercarriage cleaners
- Four in the set for a full change
- Keeps the nozzle bar at the right height
- Cheap against a new cleaner
Weaknesses
- Measure the old wheel and stem; not every housing takes 2 1/2 inch
- Plastic wheels wear again on rough concrete
- Stem hardware may differ; keep the old bolts

The Cleaner That Started Scraping
A surface cleaner that once glided across the drive starts to drag, rock and leave swirl marks, and the nozzles wear faster than they should. The wheels are the cause: a flat spot, a seized bearing or one snapped off. Erie Tools’ set is four 2 1/2 by 3/4 inch casters that bolt into the housing of most surface cleaners, water brooms and undercarriage cleaners and bring the cleaner back to its proper height.
This review is based on the listing specifications and on how surface cleaner casters wear and are replaced generally. We have not fitted these wheels ourselves.
Why the Wheels Matter
A surface cleaner is a spinning nozzle bar inside a hood, and the hood rides on its casters at a fixed height above the slab. That height sets the cleaning pattern. A worn wheel drops one side so the bar scours the concrete, leaves arcs, and the nozzles grind on grit. Fresh wheels put the bar back where the maker set it and the cleaner glides again.
Fitting
Turn the cleaner over. Each caster is held by a bolt or a stem into the housing; undo it, lift out the old wheel, fit the new one with the same hardware and tighten. Four wheels, ten minutes. Set the cleaner on a flat floor and check all four touch.
Fit
Two and a half inches is the common size on consumer cleaners from many brands, but not all. Measure the diameter of the old wheel and the stem or bolt before ordering, and keep the old hardware in case the new stems differ.
Durability
Casters on a surface cleaner live in water and grit and wear; it is a consumable on rough concrete. A set in the washer box means the cleaner is never sidelined.
Beyond the Surface Cleaner
Water brooms and undercarriage cleaners use the same casters and wear them the same way.
Who Should Buy It
- Surface cleaner owners whose cleaner drags or swirls.
- Anyone with a snapped caster.
- Owners who want a spare set for the season.
Common Owner Complaints
Wrong size for some housings. Measure first.
Technique Tips
Replace all four at once even if only one has failed, since a new wheel beside three worn ones tilts the cleaner the other way. Rinse grit out of the casters after each use and the bearings last longer.
Alternatives to Consider
The cleaner maker’s own caster kit if available. A larger caster where the housing allows. A new surface cleaner if the hood is cracked as well.
Verdict
For a surface cleaner that has lost its glide, four new casters are the whole repair and this set fits most. Measure the old wheel, keep the hardware and check the height on a flat floor.

Erie Tools Set of 4 Replacement Caster Wheels for Pressure Washer Surface Cleaners, 2 1/2 x 3/4 Inch FAQs
When the cleaner drags, leaves swirl marks it did not leave before, rocks on a flat slab or sits lower on one side. Look at the wheels; a flat spot or a missing one is the cause.
Unbolt the old caster from the housing, bolt the new one in the same hole with the same hardware, repeat for four. Check all four touch the floor on a flat surface.
Most consumer surface cleaners use a 2 1/2 inch caster on a stem or a bolt. Measure the old wheel diameter and the stem before ordering.
The nozzle bar spins a set distance above the slab. Too low and it scours the surface and wears the nozzles; too high and it cleans poorly. The wheels set that distance.
