Struggling to get those high-up windows spotless without risking a ladder or hiring an expensive service? We get it. Cleaning windows can be a real chore, but what if a little robot could handle most of the grunt work for you? Today, we’re taking a deep look at the Hobot S7 Pro window cleaning robot, a device that promises to take the pain out of polishing your panes. This isn’t just another gadget. it’s designed to be your go-to solution for crystal-clear views, especially if you have large windows, glass doors, or even tiled surfaces that need some serious attention.
The Hobot S7 Pro is a standout in the world of automatic window cleaners, thanks to its unique features like patented reciprocating cleaning pads that scrub at an impressive 600 strokes per minute, mimicking a human hand-wiping motion. It also boasts a dual ultrasonic spray system that atomizes water into a super-fine 15-nanometer mist, tackling dirt effectively without leaving your windows overly wet or streaky. With a robust 4800 Pa suction power, this bot clings securely to glass, ensuring a stable and thorough clean.
It’s an investment, usually priced around $439 / £329. You can often find it on platforms like Amazon in the US or direct from Solenco in the UK. The S7 Pro works on both framed and frameless windows, mirrors, and even glass splashbacks. While it’s fantastic for maintaining lightly dirty windows, don’t expect it to magically erase years of caked-on grime in one go. tougher dirt might still require a few passes or a bit of pre-cleaning. Think of it as your consistent cleaning partner, not a one-time miracle worker for severely neglected surfaces. You’ll still need to be present to move it from pane to pane, so it’s not entirely autonomous like some robot vacuums, but it certainly saves a ton of effort and keeps you off that ladder.
What Makes the Hobot S7 Pro Tick? Features & Design
When you first unbox the Hobot S7 Pro, you’ll notice its solid, square design. It measures about 10.5 x 10.2 x 3.5 inches 26.7 x 26 x 9 cm and weighs around 1.65 kg. This isn’t a tiny bot, so it’s definitely better suited for larger window panes. if your windows are too narrow, say less than 12.6 inches 32 cm wide, the robot might struggle to maneuver or even refuse to clean.
Dual Reciprocating Cleaning Pads
This is where the S7 Pro really stands out from many other window cleaning robots. Instead of just rotating, its dual cleaning pads move back and forth, mimicking a human’s scrubbing motion. These pads can perform an impressive 600 strokes per minute, effectively dislodging dirt and buffing your windows. This “hand-wiping” technology is designed to deliver a deeper clean and leave a streak-free, polished finish. The robot often uses an upper and lower cleaning cloth system, where the lower one tackles the initial dirt, and the upper one follows to wipe away any residual marks.
Ultra-Fine Dual Ultrasonic Spray
Forget dripping water or uneven sprays. The Hobot S7 Pro features dual ultrasonic spray nozzles that turn water into an incredibly fine, 15-nanometer mist. This micro-mist system is super effective at dissolving dirt and grime on the glass, but it uses less water, which means less mess and a reduced chance of streaks. The spray is targeted, reducing liquid waste and helping to soften stubborn spots before the pads get to work. You can use water or Hobot’s own cleaning solution in the detachable 80ml water tanks.
Powerful Suction & Navigation
To cling securely to your windows, the S7 Pro utilizes a powerful 4800 Pa suction system. This strong suction, combined with upgraded caterpillar belts, helps it adhere firmly to various glass surfaces, including slightly uneven ones, and move smoothly across them. It features AI-powered navigation and smart edge detection. This means the robot can automatically scan the window size, plan the most efficient cleaning path, and detect edges even on frameless glass to ensure comprehensive coverage without missing spots or falling off.
Smart Control: App & Remote
You’ve got options for how you control this clever cleaner. The Hobot S7 Pro comes with a physical remote control, offering a simple way to start, stop, or direct the robot. For more advanced control and features, there’s a smartphone app specifically the “Hobot Legee” app, not the general “Hobot” app. The app connects via local Wi-Fi, allowing you to choose different cleaning modes like normal, double, dry, or wet, monitor its progress, and receive voice prompts and OTA firmware updates. The voice prompts can be a bit loud and irritating for some, but they do keep you informed. Modretro chromatic cartridge console review

Performance: What to Expect from the S7 Pro
Let’s talk about how the Hobot S7 Pro actually performs in the real world. Many users, myself included, are looking for a device that truly makes window cleaning easier, and for the most part, the S7 Pro delivers.
Cleaning Effectiveness
On lightly soiled indoor glass, the S7 Pro often leaves windows perfectly clear and streak-free. The dual reciprocating pads do an excellent job of scrubbing, while the ultrasonic mist helps dissolve dirt efficiently. Good Housekeeping’s review found it “wiping up general dirt and mud with ease,” leaving windows “buffed… removing smears and streaks”. If your windows accumulate dust, fingerprints, pollen, or light grime, this robot can significantly reduce the effort required to keep them sparkling.
However, it’s important to manage expectations, especially with dirtier outdoor glass. While it will certainly make a noticeable improvement, some reviewers found that it struggled a little with tougher dirt, occasionally leaving results that were “a little streaky”. For heavily soiled windows, you might need to run the robot for multiple passes or even perform a dry pass first, followed by one or two wet passes, to achieve the best results. Think of it as a maintenance tool that keeps your windows looking good between more intensive manual cleans, rather than a complete replacement for a professional job on extremely dirty surfaces.

Speed and Efficiency
Hobot advertises that the S7 Pro can clean 1 square meter in just 2 minutes and 36 seconds. In practice, real-world tests often show it takes a bit longer. For example, one test found it cleaned a 1.3 square meter pane of glass in about 7 minutes and 30 seconds. So, while it saves you effort, it might not always save you a ton of time compared to a quick manual wipe, especially if you factor in moving it between panes. The real benefit is the hands-off nature of the cleaning itself. You can set it up and work on other tasks around the house while it does its thing.
Versatility
Beyond standard windows, the Hobot S7 Pro is quite versatile. It works well on:
- Mirrors
- Tiles
- Glass splashbacks
- Shower screens
- Patio doors
- Conservatory walls and roofs
- Loft windows and skylights
Its ability to handle both framed and frameless glass of various thicknesses is a big plus, thanks to its smart edge-detection bumper sensors.
For optimal results, consider using a good quality microfiber cleaning cloth set to regularly replace the S7 Pro’s pads, as they will accumulate dirt and need washing after each significant use.
Safety Features: Peace of Mind While Cleaning
Cleaning windows, especially high ones, can be risky business. Hobot has clearly prioritized safety with the S7 Pro, integrating several features to give you peace of mind.
Uninterruptible Power System UPS
The S7 Pro isn’t a cordless robot. it needs to be plugged into the mains to operate. This design choice is actually a safety feature, as it eliminates the risk of the robot falling due to a depleted battery during a cleaning cycle. The total cable length is a generous 21 feet 6.4 meters, extendable to 8 meters, which is usually enough for most windows, though you might still need an extension cord for some awkwardly placed outdoor panes.
However, what happens if the power goes out? The Hobot S7 Pro is equipped with a built-in Uninterruptible Power System UPS. This backup battery keeps the robot securely attached to the window for up to 20 minutes in the event of a power cut, giving you ample time to retrieve it safely. It will also play a loud alarm and send an alert to the app, so you’re immediately aware of the situation.
Safety Rope and Anti-Fall Algorithm
For an extra layer of protection, especially when cleaning high-rise windows, a safety rope is included. On the S7 Pro, this safety line is actually built inside the frame, making it less likely to detach accidentally. It’s designed to withstand extreme breaking strength, exceeding 150 kg, and engineered to withstand an impact force of up to 230 kgf. The robot also incorporates an anti-fall algorithm that works in conjunction with its sensors to prevent it from detaching. While it’s generally reliable, one review did mention it “once fell off a window, seemingly for no reason,” highlighting why the safety rope is a crucial backup.
Edge-Leakage-Bumper Sensors
These specialized sensors, along with silicone-covered bumpers, are key to the S7 Pro’s ability to navigate safely on both framed and frameless glass. They detect the edges of the window, preventing the robot from ‘leaking’ off the surface and protecting your window frames from scratches.

When using your robot window cleaner, always ensure the safety rope is properly secured, especially for external or high windows. It’s a small step that makes a big difference in preventing accidents.
Using the Hobot S7 Pro: Tips for Best Results
Getting the most out of your Hobot S7 Pro involves a few simple steps and understanding its optimal operating conditions.
Preparation is Key
- Weather Conditions: For the best, streak-free results, it’s recommended to use the Hobot S7 Pro on sunny days or days with low humidity. High humidity or rainy conditions can lead to water stains and reduce cleaning effectiveness.
- Window Condition: If your windows are very dusty or greasy, it’s a good idea to wipe a small area clean first where you intend to place the Hobot, just to give it a secure starting point. For extremely dirty windows, a preliminary dry clean pass before a wet pass can make a huge difference in avoiding streaks.
- Charging the Backup Battery: Although the robot runs on mains power, ensure the internal UPS backup battery is charged. This is critical for safety in case of a power outage.
- Fill Water Tanks: Make sure both 80ml water tanks are filled with water or Hobot’s cleaning solution.
- Attach Cleaning Cloths: Ensure the microfiber cleaning cloths are properly attached. For better results, especially on dirtier windows, you might want to moisten the cleaning pads slightly before the wet cleaning cycle.
Operation and Maintenance
- Placement: Place the robot firmly on the glass. The internal fan will create the negative pressure needed to hold it in place once it’s powered on and operating.
- Cleaning Modes: You can choose from various cleaning modes via the app or remote, including automatic routes, dry cleaning, or wet cleaning.
- Moving Between Panes: Remember, you’ll need to manually move the robot from one window pane to another, as it cannot traverse gaps or dividers on its own.
- Clean Pads Regularly: After each cleaning session, especially on dirty windows, the vibrating pads will accumulate dirt and residue. It’s crucial to remove and rinse them thoroughly after use and let them dry completely before the next session. Regularly cleaning the caterpillar belts is also recommended for optimal performance.
- Firmware Updates: Use the app to check for and install any firmware updates to keep your robot functioning optimally.
Investing in replacement cleaning cloths is a smart move, as having fresh, clean pads ready for each use will significantly improve your cleaning results.
Who is the Hobot S7 Pro For?
The Hobot S7 Pro isn’t for everyone, but it’s a must for specific types of homeowners.
Ideal Users
- Homes with Large or High Windows: If you have expansive glass panels, floor-to-ceiling windows, conservatories, or windows that are difficult or dangerous to reach, the S7 Pro is a fantastic solution. It saves you from hauling ladders and performing risky maneuvers.
- Busy Homeowners: If you value your time and want to automate tedious chores, this robot can free up significant time and effort. You can start it and let it clean while you focus on other tasks.
- Those Who Value Maintenance Cleaning: The S7 Pro excels at regular upkeep, preventing heavy dirt build-up and keeping your windows consistently clean. It’s perfect for maintenance cleans every 2-3 months.
- People with Various Glass Surfaces: Its versatility across windows, mirrors, tiles, and shower screens makes it a valuable multi-surface cleaner for homes with diverse glass elements.
Who Might Think Twice?
- Homes with Small or Very Narrow Windows: As mentioned, if your window panes are smaller than around 12.6 inches 32 cm, the robot might be too large or unable to navigate effectively.
- Those Expecting a “Set and Forget” Experience: Unlike some robot vacuums, the S7 Pro requires you to be present to move it from pane to pane and to clean the pads afterward. It’s effort-saving, not entirely hands-off.
- Budget-Conscious Buyers: At its price point, the S7 Pro is an investment. While it offers excellent features, there are cheaper alternatives like other robot window cleaners if your budget is tight.
- People with Severely Neglected Windows: If your windows haven’t been cleaned in years and are caked with thick grime, the S7 Pro might struggle to achieve a perfect, streak-free finish in a single pass. It’s more about maintenance than deep restoration.
Hobot S7 Pro vs. The Competition
When you’re looking at robot window cleaners, the Ecovacs Winbot line is often cited as a major competitor to Hobot. Both brands offer effective solutions, but they have their unique strengths.
The Hobot S7 Pro stands out with its reciprocating scrubbing pads and ultrasonic mist spray, which are designed to mimic manual hand-wiping for a deeper clean and streak-free results. It’s praised for its strong 4800 Pa suction and advanced AI navigation, making it great for unusually shaped or frameless windows. Reviewers often note its quiet operation and the ability to work on various surfaces beyond just windows.
Ecovacs Winbot models, like the Winbot W2 Pro Omni or W1 Pro, also offer strong suction e.g., W1 Pro has 2800 Pa and smart navigation, often with features like cross-spraying or advanced docking stations. While they deliver solid cleaning, the Hobot S7 Pro’s unique scrubbing motion and ultra-fine mist spray give it an edge in tackling stubborn dirt and leaving a polished finish. The Winbot W2 Pro Omni is known for cordless freedom, while the Hobot S7 Pro requires continuous power, relying on its UPS for power outages. Hdc f5500v 4k camera system review
Ultimately, the choice often comes down to your priorities. If you prioritize the most advanced scrubbing technology, precise misting, and robust safety features for a polished finish, the Hobot S7 Pro might be worth the investment. If you’re looking for a reliable performer with good features at a potentially friendlier price point, a model from the Ecovacs Winbot range might also be a strong contender.
