INTERLOCKING COMPONENTS:  Made of many components that interlock making it ONE PRODUCT. RADIAL is BOLTED, not glued. It is not serviceable, which is why we offer you RADIAL-CARE the 2-year brush plan.

UNMATCHED AGITATION: The bristles are in the right place for cleaning frames, edges, corners, and windows. 

HIGHEST QUALITY NYLON BRISTLES: RADIAL bristles will NOT DISTORT in temperatures as high as 60º

BLADE OF BRISTLES: 100% coverage of the window surface with every single stroke


FITTED WITH HYDRO-BLADE II: Making it possible to bend the water exactly where you need it

PIVOT: Designed to NEVER FAIL!! Giving you UNLIMITED ANGLES of ATTACK, including negative angles for cleaning windows below the waist. 

BASE JETS: Fitted with 'blank' BASE JETS (included in the kit), so that you can add water under the brush for a more effective downstroke. The BASE BLADE acts like a SQUEEGEE.



As we release what will be known as THE GAME CHANGER of the industry, we reflect back on the journey to get here - importantly, because, whilst RADIAL is born from CONSTRUCTOR BRUSH, it is NOT a CONSTRUCTOR BRUSH. 

RADIAL is as complete a product like a car or a smartphone. To achieve its’ complexity, it is made of many components that interlock and become ONE PRODUCT. RADIAL is bolted and glued - it is not serviceable, like a CONSTRUCTOR BRUSH.

RADIAL is THE END OF OUR DESIGN JOURNEY for the nylon bristle window cleaning brush. With PIVOT, we have no more ideas on how to improve it! The BRISTLES are in the right place for cleaning frames, edges, corners, and windows. The AGITATION POWER is unmatched by any other brush.

On May 15, 2015, we lodged a UTILITY PATENT APPLICATION in the USA for CONSTRUCTOR BRUSH - a brush that could be upgraded with slideably engaged components for agitation and rinse. Now, 4.5 years later, almost to the day, we can say “We have reached the end of the rainbow!” - We have RADIAL!

Over the journey, from the feedback of members of our Facebook Group ‘ADVANCED WINDOW CLEANING NETWORK’, we got the information we needed to continually improve and morph CONSTRUCTOR BRUSH to clean windows FASTER, BETTER, SAFER. 

We learned a lot over the few short years, from both constructive and destructive testimony - but we knew to ‘hold the course’ - we are responsible to ‘be relentless’ and ‘never give up’ on our vision, even though time is passing, and for a small, very vocal percentage of our customers, we were not meeting their expectations for ‘the technique they use to clean windows’. True? YES. We had failures and problems for SOME of our customers, and we fixed them - ‘No Man Left Behind’ is our company mantra for Customer Service.

RADIAL uses the highest quality of nylon bristle blade to work with hot water up to 60 degrees hot water without distorting. RADIAL is a ‘triple trim’ brush meaning there are three levels of bristle engagement with the glass. The more you compress the brush, the more active each blade of bristles become, until you contact the center bristle blades on the glass (ideal for breaking up debris like seagull poop) - at which point, the other two bristle blades are at OPTIMIZED WORKING ANGLES on the glass for maximum AGITATION, meaning LESS STROKES are required to effect a clean!

RADIAL is fitted with HYDRO-BLADE II+ technology to get the water exactly where you need it for the most effective rinse. HYDRO-BLADE II+ is 3D PRINTED to give us the ability to bend the water to EXACTLY where you need it to rinse corners, frames, edges, and the body of the window WITHOUT TAKING THE BRUSH OFF THE GLASS.


We even developed The REACH-iT TECHNIQUE to show you THE FASTEST WAY to get full coverage of a window with RADIAL.

Whilst RADIAL is the TOOL THAT CLEANS THE GLASS, it would not be possible without PIVOT - a perfect and flawless swivel joint that facilitates the rotation of RADIAL to an optimum angle at any time, with a small twist of your REACH-iT POLE. By angling RADIAL correctly, you can keep the area above your agitation (eg top frame) dry, so there is no dirt in your rinse water. With the same angle, you can place the radial bristles perfectly in the corner of the window frame and agitate out even the most obstinate spiders' nests. PIVOT has unlimited angles of attack, including negative angles for cleaning windows below the waist.

PIVOT is designed to never wear, never get sloppy, and therefore to NEVER FAIL. It will be delivered to you at a set tension, however, we also supply the tool so you can set the tension as you like it, from time to time.

RADIAL BRISTLES are a ‘BLADE OF BRISTLES’ with 100% coverage of the window surface in every single stroke. This means ONE STROKE is POSSIBLE to effect a clean! What is more amazing is that the TOP BRISTLE BLADE turns any HYDROPHOBIC GLASS to behave HYDROPHILIC - water ALWAYS CASCADES on ALL GLASS on the RADIAL DOWN-STROKE. This is how we can GUARANTEE that you can CLEAN WINDOWS IN A SINGLE ACTION!

Fitted to your RADIAL, are ‘blank’ BASE JETS, and in your tool kit are BASE JETS so, if you have enough FLOW-RATE and /or PRESSURE, you can add water under the brush for a more effective DOWN-STROKE (the base blade of the brush acts like a squeegee to take the dirty water off the glass, leaving the top blade, with HYDRO-BLADE II+ to create a WATER SQUEEGEE EFFECT over and past the extremities of the bristles, even when they are compressed against the window.

You know, there is so much more to explain about RADIAL, and THE REACH-iT TECHNIQUE - but we will do that in future videos - for now, be assured : With RADIAL, you will be cleaning windows so much, so much very FASTER, BETTER, SAFER - more than you can imagine (unless you already have a recent model CONSTRUCTOR BRUSH).

Instant hit!

From the moment we put this brush on section 1 of our pole my helper loved this brush. He doesn’t really like too many tools instantly but he loved it. Once I finished some interiors I came out to try it and I must say this is probably going to be the only brush we use from now on. Perry, you really did it


Solid piece of money making brush...confident it's going to do the job...

Nice brush

The Radial is a good brush, it's very solid so far en looks nice. It's easy to clean the corners of the window, and the systeem with the rinse makes sure that the water takes al the dirty stuff off the glas.
When you work on the glas at ground floor it would be better when the brush had one hinge more between the 'neck' and brush. The radial has to be in the right angle to get the best result, it's hard to keep the right angle and it takes too much time to change it every time with the clip.
Thats a free tip for Perry.

New to water fed window cleaning

I have to say from watching Perry in his videos I've learned the importance of getting a good scrub in the corners of the windows, and the Radial Brush allows me to do that even on deep framed windows. I also like how the bristles on the brush lay nice and flat on the glass. There is one thing I do wish was different, I don't like the water coming from the top of the brush. the reason is the water shoots on the top of the window frames and leaves streaks especially on vinyl framed windows if your not careful to rinse really good. other then that I like it.
