What Is Rotobrush AC Duct Cleaning?

Last updated: 2 October 2026

Short answer

Rotobrush is a mechanical duct cleaning method: a rotating brush on a flexible shaft is fed into the duct to loosen dust from the walls, while a connected vacuum extracts the loosened debris. It's a form of mechanical agitation plus extraction — the general approach industry bodies describe for source-removal duct cleaning.

Quick Summary

Wecare Home provides AC duct cleaning in Dubai from AED 250 per thermostat. The service includes Rotobrush duct cleaning, safe sanitization and before/after photo proof. Wecare has been serving customers in the UAE for 20 years.

The principle: agitate, then extract

Settled dust sticks to duct surfaces, so airflow alone doesn't remove it. Duct cleaning needs two things: something to loosen debris (agitation) and something to capture it (extraction). Rotobrush combines both in one setup.

How a Rotobrush pass works

Vent covers are removed to give access to the duct.
A brush head sized to the duct is attached to a flexible rotating shaft.
The shaft is fed along the duct while the brush spins against the walls.
Vacuum hose extracts the loosened debris back through the machine.
The technician checks the duct and takes after photos.

Where it fits — and its limits

Rotobrush suits round and flexible duct runs that are reachable from vent openings. Very long runs, sharp bends or damaged ducts may limit reach, and the method doesn't repair leaks or replace worn ducting. Results are best checked by photos of the same duct before and after.

Questions to ask any provider

Is the brush size matched to my duct size?
Is debris extracted during brushing?
Will I get before/after photos of inside the duct?

FAQ

Is Rotobrush suitable for flexible ducts?＋

Generally yes, with a suitable brush head and care from the technician. Damaged or very old flex duct may need assessment first.

Does Rotobrush clean the AC unit itself?＋

No. It cleans duct runs. The indoor unit, coil and drain tray are covered by the separate Full AC Unit Clean add-on.

How do I know the brushing worked?＋

Compare before and after photos of the same duct section.
