Below is a simple way to understand what each piece of window cleaning gear is called, what it’s used for, and which kit reaches which height (single storey vs double storey vs triple storey). Window Washing South Africa sells kits and equipment designed around building height (ground floor, 1-storey, 2-storey, 3-storey) and reach ranges (4m, 6m, 9m). Source

The names of the equipment (and what each is used for)

Window cleaning squeegee

The finishing tool. After you scrub the glass wet, the squeegee removes the water in controlled strokes for a streak-free finish. Your 45cm squeegee is a stainless-steel channel with replaceable rubber (so you replace the rubber when it wears rather than replacing the whole tool). Source

Window washer / scrubber (washer + sleeve)

The scrubbing tool. This is what you use to wet the window and lift dirt/film before you squeegee. Your 45cm washer comes with a sleeve and is designed to fit onto a telepole (so it works for both normal hand-cleaning and higher windows). Source

Bucket

The solution holder. You dip and rinse your washer here and keep your mix ready. The Basic Kit includes a 15L bucket as part of the starter setup. Source

Telepole / telescopic pole (4m / 6m / 9m)

The reach tool. A telescopic pole extends your reach so you can clean higher windows from the ground (less ladder time). Your kits are built around common “reach bands” like 4m, 6m and 9m for increasing building heights. Source

Waterfed pole system (RO / pure water)

The scale tool. A waterfed setup uses purified water (reverse osmosis) through a pole/brush system, typically used for hard-to-reach exterior glass and when you want a faster system-based workflow. The 6m and 9m waterfed kits are described as cleaning windows up to 6 metres and up to 9 metres using RO water. Source Source

How far each kit reaches (what height it’s for)

Think of it like this: the metre rating is reach, and the “storey” label is the typical home/building height it covers.

Ground floor (starter / ladder use)

Best for: ground-floor windows and occasional ladder work.
What you get: the core hand tools (washer + squeegee + bucket).
Recommended: Basic Window Cleaning Kit (includes 35cm washer + sleeve, 35cm squeegee, 15L bucket). Source

---

4m kits (single storey + unusually high windows on a single storey)

Best for: single-storey homes, and especially those “too high for comfort” windows on a single storey (entrance glass, stairwell windows, double-volume features where you still don’t need full double-storey reach).
Window Washing lists a 4 Metre Window Cleaning Equipment Kit as “perfect for single storey buildings” and built around a telepole that extends 2m to 4m. Source

---

6m kits (double storey / two-storey reach)

Best for: typical double-storey houses and two-storey work.
Why: Window Washing’s 6m reach products and kit pages are consistently positioned around multi-storey access and 6m reach. The 6m Waterfed Pole Kit explicitly states it’s for cleaning windows up to 6 metres using reverse osmosis water. Source

If you want the “traditional” kit route (squeegee/washer/bucket + pole), your kits page includes 6 metre extendable telepole options under the kits range. Source

---

9m kits (triple storey / three-storey reach)

Best for: typical triple-storey houses, townhouses, and higher access where 6m is no longer enough.
Two strong references on your site: The 9m Waterfed Pole Kit says it’s for cleaning windows up to 9 metres using reverse osmosis water. Source
Your 9 Metre Window Cleaning Equipment Kit is described as “perfect for triple storey buildings” and includes a pole that closes to 3m and opens to 9m. Source

What you need (based on what you’re cleaning)

If you’re a homeowner cleaning ground floor windows

Start with: washer + sleeve + squeegee + bucket.
The simplest match is the Basic Window Cleaning Kit. Source

If you’re a homeowner with “single-storey but high” windows

Start with a 4m kit (reach without overbuying).
That’s specifically what the 4m kit is positioned for: single storey buildings with added reach via a 2–4m telepole. Source

If you’re a first-time pro doing double-storey homes

You’ll usually want a 6m reach solution so height doesn’t limit you.
If you want pure-water workflow: 6m Waterfed Pole Kit (windows up to 6m). Source
If you want the more traditional kit approach: choose a 6m kit from the window cleaning kits range. Source

If you’re cleaning triple-storey homes (or want to be ready for them)

You’re in 9m territory.
For pure-water: 9m Waterfed Pole Kit (windows up to 9m). Source
For traditional reach: 9 Metre Window Cleaning Equipment Kit (positioned as triple-storey). Source
