Gardena’s blind brush is a total flop – it drenches everything in water

Screw the brush onto the hose, scrub the blinds and slats and you’re done. What sounds great in theory ends up creating a lot of annoying extra work in practice.
When it comes to window-cleaning, I prefer to look the other way. I really don’t like doing it. Thanks to my robot, at least the window panes are clean without me having to do much. The blinds, however, have been neglected by me for years. They’re a pain to clean, and it’s not like I look at them much anyway. They live outside, I live inside.
Still, at some point I do start to see the dirt and know that it’s time to clean them. Maybe there’s a gadget that can help me? I browse through our product range and find what I’m looking for: the Gardena Cleansystem Blind Brush sounds promising.
Both sides cleaned in one go
Full of anticipation, I start cleaning. What’s important to know is that the brush only works when used with a garden hose and a constant water supply. Luckily, there’s a water connection on my balconies.
Thanks to the standardised quick-connect fitting, I just snap the brush head onto the hose and get started. The attachment is designed for slats up to eight centimetres deep. The minimum distance between two slats should be five centimetres. In my case, the gap at the very top is very narrow. I need to bend the slat a little, but it just about works if I’m careful.
The brush is designed so that you can wedge the slat between the bristles. Then you press the button on the handle, and water sprays out of the nozzles. This cleans the slat from both the top and the bottom at the same time. It’s a quick and efficient affair. I just give the brush a quick swipe to the left and right and everything is clean.
Cleaning the area at the outer edge near the slats – between the lift cord and the guide rails – is less straightforward. Depending on the blind, I only have eleven to fifteen centimetres to play with, so it’s hard for me to get to.
The design means cleaning’s a pain, full stop. Whether you’re using the Gardena brush or wiping by hand. The slats I’m dealing with are divided into three to five sections – each separated by the fabric straps that open and close the blinds. For each slat, I have to reposition the brush three to five times and make sure it’s in the right place. In my case, that’s 120 to 150 segments per blind. In total, there are nearly 1,000 sections I have to clean one by one. No wonder I’ve preferred to ignore them until now.
The window panes get wet, too
While the brush scrubs the slats on both sides at the same time, it also creates extra work for me. Why? Because the brush needs vast amounts of water to clean effectively. And so, the slats start dripping, and the window panes get wet, as does the balcony floor. Not to mention my trousers and slippers.
My clothes and the floor are the least of my worries. The drops that remain on the slats and window panes after air-drying are annoying. To get a decent result, you have to dry the slats and the panes with a cloth.
Honestly, I would be just as fast if I were using a damp and a dry cloth. This would also keep my surroundings dry, so I wouldn’t have to clean the windows after I’m done with the blinds. My dream of quick and easy slat cleaning? Crushed. The Gardena brush isn’t very useful.
So why has the Community given this product so many positive reviews? Depending on your needs, the blind brush will probably make the job easier. For example, if you’re dealing with really dirty roller blinds that you can’t just clean with a microfibre cloth.
If you’re planning to clean your entire window area in one go anyway, you probably won’t mind the splashes on the panes. The same blinds to awnings that are exposed to the wind and weather. Any water stains will simply be washed away the next time it rains.
In a nutshell
Disappointing for my intended use
The Gardena blind brush sprays water under pressure onto both sides of the slats and scrubs them clean. It’s effective and quick but also makes quite a mess. Everything gets wet: the floor, the window frames, the window panes and the blinds. To get a tidy result, you have to dry everything off and clean the windows. As a result, this hardly saves me any time, so I’m not a fan.
The brush may be useful for very dirty blinds or those that are exposed to rain and therefore don’t need to be dried afterwards. But there’s no way around getting your windows wet.
