Intuitive and convenient control
With just a few steps, the robot can start cleaning. It has strong suction power to hold it firmly in place, and you can easily choose the cleaning mode using the remote control without slipping.
Innovative water spray system
The robot uses a water spray system with two metal nozzles to distribute the liquid evenly, and a microfiber cloth to clean dirt from the window. This system allows the robot to clean windows more efficiently and quickly than many other models available on the market.
Continuous work
The HESTER window cleaning robot is capable of cleaning up to 1000 windows simultaneously! This robot works while plugged into an electrical outlet, unlike most other rechargeable models, which means that it will not discharge and will clean whenever you want it to.
The robot returns to the starting point when finished
Rounded corners ensure the safety of the surfaces
Works with a cable, so you can clean thousands of windows at once
High-quality microfiber cloths for better surface cleaning

HESTER M3 PRO Extraordinary tool for ordinary people
I used to put off cleaning the windows because it always felt like such a big job. Since buying this, I just clean a couple whenever I've got a bit of spare time. It's really simple to use, sticks securely to the glass and leaves everything looking much cleaner than I expected. It's made keeping on top of the windows so much easier.

I'd seen quite a few videos online and wasn't sure if it would actually work as well at home. Thankfully it does. It was easy to get started and after using it a few times I don't think I'd want to go back to cleaning the windows by hand. Definitely one of the more useful things I've bought recently.

With two kids and a dog, our patio doors never stay clean for long. I bought the Hester M3 hoping it would save me a bit of time and it's done exactly that. I usually set it going while I'm doing something else around the house and come back to clean, shiny glass. It's become part of my weekly routine now.

I wasn't expecting perfection, but I have to admit it impressed me. It takes care of the job with very little effort from me and the windows always look much better afterwards. It's one of those things you don't realise you'll use so often until you own one.

I honestly thought this would end up sitting in a cupboard after a couple of weeks, but I use it almost every weekend now. Cleaning the windows used to be one of those jobs I'd keep putting off. Now it's quick, easy and I don't really have to think about it.

I spent ages looking at different window cleaning robots before deciding on this one. Setup was straightforward and I had it working within a few minutes. We have large windows and cleaning the outside was always awkward, especially upstairs. This has made the whole job much easier and the finish is far better than I expected.

Working from home means I notice dirty windows much more than I used to. Before buying this, I'd only clean them every couple of months because it took so long. Now I just put the robot on while I'm answering emails or making lunch. It stays firmly attached and leaves the glass looking really clean. I'm very pleased with it.

My husband kept saying we didn't need a window cleaning robot, but he changed his mind after the first weekend. We both hate cleaning the big windows at the back of the house and this has taken most of the effort out of it. I only wish we'd bought one sooner.

I don't usually write reviews, but this deserved one. My main reason for buying it was the upstairs windows because I never liked climbing ladders. Now I can get them cleaned without worrying about that. It's easy to use, gives consistent results and has saved me a lot of time already.

I'll admit I was a bit sceptical because I've bought plenty of gadgets that looked great online but never really lived up to the hype. This one actually does. It moves steadily across the glass, leaves very few streaks and has made cleaning the upstairs windows much less of a chore. For me, not having to get the ladders out anymore is worth it on its own.
