What Equipment Does a Window Cleaner Need?

Starting a window cleaning business is one of the easiest ways to become your own boss. With relatively low start-up costs and minimal licensing or certification, you can begin earning quickly — even if you’re completely new to the industry.

Many people imagine window cleaners climbing ladders all day, but modern window cleaning has changed. Thanks to pure water systems and water-fed poles, most professional cleaners rarely need to work at height. In fact, you could build an entire business cleaning houses and low-level commercial properties without ever stepping on a ladder.

Whether you're starting small or planning to invest in a full modern setup, here is the equipment you’ll need.

1. Modern Window Cleaning Kit (Water-Fed Pole System)

A modern window cleaning kit is built around a water-fed pole and a pure water filtration system. This setup allows you to clean windows from the ground safely, quickly, and without leaving streaks.

The system includes:

• Extendable water-fed pole with an adjustable brush head for hard-to-reach windows
• RO/DI filtration system to produce purified water (view filtration options)
• Hoses, connectors, and fittings

Pure water contains no minerals or contaminants, so it dries spot-free without needing a squeegee. This saves time, reduces physical effort, and allows you to take on bigger jobs with ease.

If you're starting with a smaller budget, you can still use a basic DI vessel and pole for residential properties — no ladders required.

2. Traditional Window Cleaning Kit

If you're focusing on residential work, traditional tools are still essential. A complete window cleaning kit helps you achieve professional results on any job.

T-Bars & Sleeves

Your washer (T-bar + sleeve) applies the cleaning solution to the glass. Choose a sleeve with high water absorption for efficient coverage. View options here: applicator T-bars.

Scrapers

A glass scraper removes stubborn dirt, paint, and debris safely. Always use sharp blades to avoid scratching.

Cleaning Solution

Keep it simple: a quality window cleaning detergent does the job perfectly. You can find professional solutions here: window cleaning solution.

Buckets

Use a wide bucket that fits your T-bar to avoid spills and work efficiently.

Microfibre Cloths & Scrims

Liberally stock up on lint-free microfibre cloths for detailing frames, edges, and finishing work.

Squeegees

A high-quality squeegee is essential for streak-free glass. Choose professional channels and rubber for the best results.

Tool Belt

A tool belt keeps your key tools at hand and speeds up your workflow.

Ladders

Although used less often today, a sturdy ladder is still useful for certain access situations.

Pouches

Pouches help you carry your phone, cloths, and personal items safely while working.

• Ladder clamps
• Ladder mitts
• Telescopic poles for high traditional work

• Bucket-on-a-belt

These extras make your day-to-day work safer, easier, and more efficient — especially once you start taking on regular customers.
