Escalator Step and Edge Cleaning
Escalator steps and walkway pallets are kept clean with fixed strip brushes the treads run past: groove brushes that reach the bottom of each cleat ahead of the comb plate, riser brushes that wipe the cleated face, and skirt brushes that guard the step-to-skirt gap. The fill is flame-retardant, low-shedding nylon or PBT.

Why do escalators need brushes?
Every escalator step and moving-walkway pallet is cleated: rows of grooves that mesh with the teeth of the comb plate at each end. Grit, sand and fiber carried in on shoes pack into those grooves. Once they are full, the comb teeth ride up on the debris, which wears them, and in the worst case jams them or lifts the plate.
Fixed strip brushes mounted in the escalator clear the grooves continuously as the steps pass, without stopping the unit. Others wipe the riser faces. A third kind, the skirt brush, runs along the side panels; it is a safety guard that keeps feet, shoelaces and clothing out of the gap between step and skirt.
Because they sit in a public space, escalator brushes are usually specified flame-retardant and low-shedding.
Which parts of an escalator use brushes?
| Part or area | Residue type | Cleaning requirement |
|---|---|---|
| Step Groove | Grit and debris packed in the grooves | Reach the bottom of each step cleat and clear packed grit. |
| Step Riser | Dirt and grease on the riser | Wipe the cleated riser face as it passes, without catching. |
| Skirt Panel Edge | Dust and grime along the skirt | Keep light contact along the skirt panel with flame-retardant fill. |
| Comb Plate | Debris caught in the comb teeth | Sweep debris out of the cleats before the comb plate teeth. |
| Moving Walkway | Grit and fiber in the pallet grooves | Span the pallet width and clear grit from the grooves along the run. |
Ranges for the strip brushes we make:
| Parameter | Typical range |
|---|---|
| Strip length | 100–3,000 mm per piece |
| Trim height | 12.7–152.4 mm |
| Filament diameter | 0.05–1.27 mm |
| Holder | Aluminum, steel or PVC channel, or a custom profile |
| Contact setting for wiping | 5–15% compression of the trim |
Which strip brush goes where?
| Cleaning target | Recommended brush type | Why it fits |
|---|---|---|
| Step Groove | Strip Seal Brushes | The step grooves must stay clear for the comb plate to mesh, so a fixed strip brush clears each groove as the step passes under it. |
| Step Riser | The riser is a cleated face moving continuously past a fixed point, so a strip brush mounted there wipes the whole face without stopping the unit. | |
| Skirt Panel Edge | The skirt brush runs the length of the panel to keep feet and debris out of the step-to-skirt gap, so here the brush is a guard as much as a wiper. | |
| Comb Plate | The comb plate is where everything carried up the steps arrives, so a strip brush ahead of it sweeps the grooves before the teeth can jam. | |
| Moving Walkway | A walkway is the same tread running much further, so a full-width strip brush is what keeps grit out of the grooves along the whole length. |
Groove brushes are set so the fill reaches the bottom of the cleats, with enough trim to bend over the cleat tops without wearing flat. Mount them across the step path just ahead of the comb plate, where the grit would otherwise arrive.
Skirt brushes run in an aluminum holder along both side panels, fill pointing towards the steps. The escalator maker or the applicable code sets their position; we build the strip and holder to that drawing.
Which fill suits escalator brushes?
| If the condition is… | Filament to start with | Why |
|---|---|---|
| Skirt brushes and indoor groove brushes | Nylon PA | Springs back after constant contact, available in flame-retardant grades |
| Outdoor escalators and wet entrances | PBT | Takes up little water and keeps its stiffness in rain and washdown |
Send the fire and smoke requirement of the building or transit project with the enquiry, and the fill and holder are chosen to it. Specify low-shedding fill: loose filament ends up in the same grooves the brush is meant to keep clear.
How are escalator brushes maintained?
- Inspect brushes at each scheduled escalator service.
- Reset or replace groove brushes once the fill no longer reaches the cleat bottoms.
- Replace skirt brush sections with gaps or flattened fill straight away; they are a safety part.
- Vacuum the comb plate area and step grooves during deep cleaning.
What do we need to quote escalator brushes?
- Escalator or walkway make and model, or a drawing of the brush position.
- Which brushes: groove, riser, skirt or comb plate.
- Strip lengths, trim height and holder profile.
- The fire and smoke requirement.
- Quantity per profile; the minimum for medium and large brushes is 100 pieces.
When can a brush not fix an escalator problem?
Broken comb teeth, damaged cleats and a step-to-skirt gap that is out of tolerance are mechanical faults for the escalator technician. A skirt brush reduces the risk at the gap; it does not correct a gap that is too wide.
What mistakes make escalator brushes fail?
- Groove brushes too short to reach the bottom of the cleats.
- Skirt brushes left in service with gaps in the fill.
- Fill that is not flame-retardant where the project requires it.
- Over-compressed brushes that wear flat within weeks.
Questions buyers ask about Escalator Step and Edge Cleaning
What does an escalator skirt brush do?
It runs along the side panels and keeps feet, shoelaces and clothing out of the gap between the steps and the skirt. It is a safety part: replace sections with gaps or flattened fill at once.
Why do escalator step grooves need a brush?
Grit packed into the cleats stops the comb plate teeth from meshing, which wears or jams them. A fixed groove brush ahead of the comb plate clears each groove as the steps pass.
