Double Layer PU Aircon Cleaning Bag (Wall-Mounted Split Systems)

This double layer PU air-conditioner cleaning bag is made to catch dirty rinse water while you clean a wall-mounted split system indoor unit. It helps keep splash, run-off, and overspray off your walls, floors, furniture, and skirting boards—especially in lounge rooms, rentals, and kids’ areas.

✅ Helps reduce mess during indoor coil rinsing and filter washing

✅ Double-layer waterproof build with PU sealing strip for fewer drips

✅ 20 mm outlet supports faster drainage into a bucket

✅ Choose Medium or Large, with or without a drain pipe option

✅ Reusable—rinse, dry, and store for the next seasonal clean

Features & benefits

When water starts moving, a basic cover can drip at seams or shift out of position. This bag is designed to stay more controlled during rinsing, so you spend less time mopping up and more time actually finishing the clean.

✅ Helps contain run-off so it drains where you want it (into a bucket)

✅ Helps protect paintwork, curtains, and furniture from splash-back

✅ Handy for DIY users, tradies, cleaners, and property managers

Why the PU layer matters

The bag uses a double-layer waterproof fabric with a PVC coating and a PU sealing strip. That PU sealing helps create a tighter barrier along edges and seams—where leaks usually start.

✅ PU sealing strip helps reduce edge drips

✅ Double-layer build helps handle heavier rinsing

✅ Anti-friction surface suits repeat setup and pack-down

Fit & sizing for wall units

This is a universal-style bag for common wall-mounted split systems. Pick the size that best matches your indoor head, then use the elastic strap and cord fastener to snug the opening.

✅ Size options suit 1P–1.5P and 2P–3P wall-mounted units

✅ Elastic strap + cord fastener help you adjust and reduce gaps

✅ Snug fit helps keep splash-back down while you rinse

Fast draining outlet (20 mm)

The outlet is designed for fast drainage, which helps reduce pooling during a more thorough rinse. Faster drainage = less chance of overflow and fewer “oops” moments mid-clean.

✅ 20 mm outlet supports faster drain speed

✅ Helps guide dirty water into a bucket instead of onto the floor

✅ Helps keep the bag stable during longer rinses

Use with a drain pipe (or go without)

This product has options with or without a drain pipe. Both work—your choice mainly depends on where the bucket must sit.

Best with a pipe

Use a pipe when the unit is high on the wall, the bucket needs to sit further away, or you’re cleaning near carpet and want a cleaner drainage path.

✅ Cleaner drainage into the bucket with fewer drips along the way

✅ Easier to manage if you’re cleaning solo

✅ Extra setup step, but usually worth it for neat results

Best without a pipe

Go without a pipe for quick maintenance rinses when you can place a bucket directly under the outlet.

✅ Fastest setup for light cleans

✅ Less gear to store

✅ Higher chance of drips if the bucket position shifts

How to use (quick steps)

1. Turn power off at the isolator/switchboard before cleaning.
2. Place a bucket under the outlet. If using a pipe, secure it into the bucket.
3. Fit the bag around the indoor unit and tighten the strap/cord to reduce gaps.
4. Rinse gently from top to bottom so run-off flows into the bag and out the outlet.
5. Let it fully drain, wipe down nearby surfaces, then remove the bag.

Care & storage

Rinse the bag after use, air dry completely, then store it out of direct sun. A dry bag lasts longer and is nicer to reuse next season.

✅ Designed for wall-mounted split system indoor units
