Interior painting robot · built for crews

Your crew cuts in. It rolls the rest.

WallRoller is a positionable painting robot for residential and light-commercial work. Wheel it to a prepped wall and it rolls the open face with consistent pressure, baseboard to ceiling line — while your painters do the cut-ins, trim, and finish work that needs real hands.

How a job runs, wall by wall

WallRoller doesn't try to paint the whole room by itself. It slots into the way crews already work — and takes over the slowest, most repetitive part.

STEP 1 — OFFICE

Assess the job

Photos and measurements from the walkthrough. Pre-job AI flags obstructions and scores which walls the robot can take.

STEP 2 — CREW

Cut in

Your painters do edges, trim, and ceiling lines exactly as they do today. No masking a lived-in home for spray.

STEP 3 — OPERATOR

Position

Wheel WallRoller to the wall. Big rubber wheels handle thresholds and job-site floors; it fits through standard doorways.

STEP 4 — ROBOT

Roll

The depth camera locks the wall plane. The roller covers the open face in even, pressure-controlled passes.

STEP 5 — REPEAT

Next wall

Move it, top off the reservoir, start the next face. The crew keeps cutting in ahead of it.

Why hybrid? Skipping full-room autonomy is the point — it keeps the robot light, simple, affordable, and dependable on real job sites.

The robot does the reps.
Your painters do the craft.

ONE PASS · 6 SEC

Watch a single pass

00:00
Plane lock. The depth camera and IMU confirm the wall plane and standoff distance before the roller touches paint.
00:02
Contact. The compliant mount loads the roller against the wall at a set pressure — not too light, not squeegeeing.
00:03
The pass. The mast drives the roller through a full-height stroke at constant speed for an even film.
00:06
Home. Roller returns, indexes over, and the next stroke overlaps the last — like a good painter, every time.

Painting robots exist. They're built for a different job.

Today's systems are spray-based machines aimed at high-volume new construction — heavy, complex, and priced for general-contractor fleets. WallRoller is aimed at the crews doing the repaint work all around them.

Overspray & masking

A roller finish

Rollers are how residential walls are actually painted. No atomized paint drifting through an occupied home, no hours of masking — the finish clients already expect.

Construction machinery

Fits in the van

At 40–70 kg with real wheels, WallRoller loads like a piece of crew equipment, not a machine that needs a trailer and a site plan.

$10k–$50k+ GC fleet pricing

Priced for contractors

Built to pay for itself on crew productivity for a regional painting company — not amortized across a national construction fleet.
