1-minute Hobot 388 review

The Hobot 388 is a premium window cleaning robot designed to polish off dust and cleans large rectangular windows. Using a suction force it vertically attaches itself to a window pane while a forceful vacuum sucks off dust particles and the soft synthetic fibers of the cleaning cloths thoroughly wipe the windows clean.

Two cleaning wheels help it work its way from left to right and around the windows, these wheels are wrapped with microfiber cleaning pads to prevent the robot from leaving tracks and marks as it moves around the windowpane.

Unlike other window cleaning robots that require you to spray copious amounts of cleaning solution on the pads, the HOBOT-388 has a reservoir with an ultrasonic spray head that efficiently applies a uniform mist on the very dirty windows. 

It also has a 4.5-meter long safety rope with the sole purpose of attaching the robot to an indoor fixture while in use, which is an anti-falling control in case of an accidental fall. This smart home gadget is designed to use Biomimicry Technology Ultrasonic Water Spray to nebulize water to dense mist and spray through a zigzag nozzle to clean windows.

Hobot 388 robotic window cleaner – full review

Chores become fun when you have home robots to do them and the Hobot 388 is just the robot for having fun while your windows are cleaned. With this robot, the tedious household chore becomes one less thing to worry about. It’s designed to get your windows from dusty to shiny and spotless, with a smooth cleaning process. Instead of caterpillar tracks or rubber wheels, the Hobot 388 uses cloth-covered moving wheels that won’t leave behind tracks on the cleaned surface.

The five-foot power cord allows the HOBOT to work on a large area even when the power outlet is far from the window. When coupled together, the power cord coming out of the power supply and the extension cable is about 16 feet long. This should be sufficient to let the bot move on most windows. 

However, the connection between the power and extension cable is only a simple press-on connection. You might want to wrap the connection with electrical tape to make sure they stay together during operation. Works on Other Surfaces The HOBOT window robot isn’t only for cleaning windows. It can also clean mirrors, tiles, and mosaics. The HOBOT works on surfaces other than windows because of a high-volume centrifugal pump that creates negative pressure.

If the power goes off, an integrated UPS (Uninterrupted Power System) will act as battery backup and power the robot for another 20 minutes to prevent it from falling off the window before you come to take it off. It also has a 4.5-meter long safety rope with the sole purpose of attaching the robot to an indoor fixture while in use, which is an anti-falling control in case of an accidental fall.

This smart home gadget is designed to use Biomimicry Technology Ultrasonic Water Spray to nebulize water to dense mist and sprays through a zigzag nozzle which dissolves dust while two specially-designed rotating pads wipe the surfaces without leaving watermarks or streaks. Also, this robot has an AI technology that draws on human intelligence to ensure high cleaning performance. Hobot 388 can work on different surface types, thanks to a high volume centrifugal pump which consistently creates negative pressure to enable the robot to attach to and move over rough surfaces despite small air leakages.

How the Hobot 388 works

The 388 window cleaning robot is a simple but somewhat sophisticated gadget. It comes equipped with a vacuum motor, two specially-designed cleaning wheels wrapped with a microfiber cloth, and together they enable the Hobot 388 to smoothly move over glass windows polishing away dust and stains.

This automatic cleaning robot follows a simple cleaning process, it gradually moves horizontally on the window surfaces and from top to bottom wiping off dirt particles and a forceful suction power sucks off a large proportion of dust particles. The robot first goes over the window to clean with dry cleaning pads, while moving horizontally on the surface, from top to bottom in a clever cleaning pattern. The soft fabric of the cleaning pads absorbs dust particles and thoroughly wipes the surface.

Then it proceeds to clean with water or a cleaning solution. It uses the new patented ultrasonic water spray nozzle that can nebulize water to 15-micrometer mists then sprays the specially-formulated Hobot Window Detergent on the glass, this looks just like when a human exhales on a glass surface and allows the robot to glide over it without leaving streaks.

It has 3 kinds of automatic operation modes for cleaning the entire window and you can either control it via an iOS app and Andriod app or with the included remote control. This Hobot has a noise level of 70dB which may be not very quiet, but not so loud as to disrupt your normal home activities. Most of the noise comes from the motor that creates the vacuum that holds the robot tightly against the pane. The Hobot 388 automatically stops once it has thoroughly and completely cleaned the window.

Cleaning Performance of the HOBOT-388

It is important to realize that despite being a premium robotic window cleaner, the Hobot 388 still has its limitations. It’s designed for only rectangular windows since it cleans horizontally from left to right and from top to bottom, and it works perfectly on window edges. An in-built pressure change detection module enables it to automatically change direction when there is a big change in pressure.

It’s also worth remembering it is also a robot, so it won’t do the job as well as you would do it yourself. While you will certainly have cleaner windows, they are unlikely to be as perfect as a bit of elbow grease can give. But, temper your expectations and you may be pleasantly surprised.

On triangular or circular windows, the result will be less-than-perfect because the robot will be unable to reach some areas on the window pane. It also doesn’t work on just any glass, the ideal glass thickness needs to be at least 3 mm and a minimum surface size of 13×13 inches. The HOBOT-388 works best on low humidity days with lots of suns because glass surfaces must be completely dry before the robot can do its thing.

Also, it will struggle to find the edges of frameless windows and mirrors, so it is best not to use this model on glass without frames.  So if you have a lot of large windows this is simply a must! Hobot works best on sunny and low humid days because the surface to be cleaned needs to be completely dry before you introduce the robot. If there are water molecules on the window surface, this will negatively affect the result because the surface will be slippery for the robot cleaner and it may leave visible streaks.

For very dusty windows, this window cleaning robot will first need to use dry pads to clean off dust particles before using the cleaning solution to wipe a second time. If you let the robot clean a very dusty surface with wet pads you’ll get a messy result because the dust particles will mix with the water or cleaning solution and both the glass surface and cleaning cloth will get mucky.

Ease of set-up and use

Setting up and using the Hobot 388 is as easy as pushing a button, it requires absolutely no special skill. To get a Hobot 388 working on your window, first, you’ll have to charge it fully, then place it on the surface to be cleaned and plug it into a power source, attach the safety cord to it and fasten it to an indoor fixture, then push the start button on the robot and watch it get to work.

This robot also comes with intuitive remote control and a user-friendly smartphone app (which is available for Android and iOS) with auto-cleaning buttons for easily controlling the robot, and it will automatically stop once it has finished cleaning the window. A user manual is included in the box, to walk you through a seamless set-up process.

The HOBOT produces such superior, streak-free results, you’ll never have to go through the trouble of washing a window by hand or multi-story windows.

Reliability

As an automatic window cleaner, you can rely on it to do a good job of cleaning your rectangular windows. It’s an excellent gadget for keeping your windows neat without you having to do it yourself and if properly maintained this robot will serve you well.

The ultrasonic spray nozzle is designed to work with just water or the specially formulated Hobot Window Detergent. Every once in a while this nozzle may become clogged and when this happens you will have to remove the water tank to clear it and get the robot working well again.

Ongoing maintenance

Hobot 388 is designed to do its work with very little maintenance and keeping it running and in good shape requires very little effort. First, you’ll have to clean the laser sensors before every use with a soft clean cloth.

The microfiber pads will also need to be washed after every cleaning, this mainly depends on how dirty your windows can get. It’s important to check the user manual that comes with the robot for other maintenance tips to keep your little machine in perfect shape at all times.

Extra purchases and ongoing costs

Getting this robot started on your windows requires no extra purchases because everything you need to put it to work is included in the pack including multiple pairs of microfibre pads.

FAQs

Does the Hobot 388 only have glass surfaces?

No, the 388 isn’t only for cleaning windows and glass surfaces. It can clean different surface types; window glass, mirrors, tiles, and mosaic can all be cleaned with this gadget. It’s equipped with a high-volume centrifugal pump that consistently supplies negative pressure, enabling the robot to move well on both smooth and rough surfaces despite small air leakages.

Can I use it outside my window?

Hobot 388 can clean both inside and outside your windows. Although before placing it on your window ensure you attach the safety line to an indoor fixture as an anti-fall measure and also connect the power cord.

How well does it stay vertically on the window?

This window cleaning robot uses strong suction to attach itself to vertical surfaces. It’s also able to overcome small air leakages and stay glued to rough surfaces because of a high-volume centrifugal pump. And when there is a power outage, an embedded UPS acts as a backup battery to keep it on the window for up to 20 minutes.

Can this window cleaning robot also clean triangular windows?

The Hobot 388 window cleaning robot does a commendable job on rectangular windows but you can’t say the same for triangular windows. With triangular windows, the robot will only clean the places it can get to and leave out corners too tight for it. It also doesn’t do so well on circular windows it’s designed for rectangular windows only.

What size windows can the Hobot 388 clean?

This robot can clean only as far as its safety cord permits, but you can extend this cord. It comes with a 5-meter long power cord and a 4.5-meter long safety rope. For the safety line, you can extend it using a regular cord. But since it needs to be connected to a power source while working, the power cord will need to be plugged into a socket that’s very close to your windows and you can always use an extension cord.
