1-minute Hobot 388 review

The Hobot 388 is a premium window cleaning robot designed to polish off dust from 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 wipes 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 window-pane.  

With a water tank and an ultrasonic water spray nozzle, it evenly wets the window for the cleaning pads to smoothly glide over leaving a spotless glass.

Hobot 388 robotic window cleaner – full review 

Chores become fun when you have 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 and boring window cleaning chore becomes one less thing to worry about. 

It’s designed to get your windows from dusty to shiny and spotless. 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. 

Since it needs to stay plugged to a power supply while working, Hobot 388 has a 5-meter long power cord that permits it to work on large windows and the screw-in DC power jack design prevents disconnection.

If the power goes off, an integrated UPS will 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 cord with the sole purpose of attaching the robot to an indoor fixture while in use, this keeps the robot safe in case of an accidental fall. 

Note, at some point, it probably will fall so please remember to attach the cord.

This smart home gadget is designed to use Biomimicry Technology Ultrasonic Water Spray to nebulize water to dense mist which dissolves dust while two specially-designed rotating pads wipe the surfaces without leaving watermarks or streaks. 

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

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

This automatic cleaning robot gradually moves horizontally on the window surfaces and from top to bottom wiping off dirt particles. The robot first goes over the window to clean with dry cleaning pads, the soft fabric of the cleaning pads absorb 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.

It has 3 kinds of automatic operation modes for cleaning the entire window and you can either control via smartphone app or with the included remote control. 

The Hobot 388 automatically stops once it has thoroughly and completely cleaned the window. 

Performance 

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. 

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 needs to be at least 3 mm thick and a minimum surface size of 13×13 inches.

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. 

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 end result because the surface will be slippery for the robot cleaner and it may leave visible streaks.

For very dusty windows, the Hobot 388 will need to first use dry pads to clean off the dust 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 detergent and become 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 to 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 for easily controlling the robot. Hobot 388 automatically stops once it has completely cleaned the window.  

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 is nozzle is designed to work with just water or the specially formulated Hobot Window Detergent. Every once in awhile 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.

Extra purchases and ongoing costs 

To get 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. 

You may also want to shop for some Hobot Window Detergent because it’s formulated to work with the ultrasonic spray nozzle the robot comes with, otherwise, you can use just water. 

FAQs

Does this robot clean only glass surfaces?

No, the Hobot 388 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 which 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 on your window ensure you attach the safety cord to an indoor fixture for safety and also connect the power cord. 

How well does it stay vertically on the window? 

This window cleaning robot uses a 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 integrated UPS keeps it on the window for up to 20 minutes.

Can this window cleaning robot also clean triangular windows? 

The Hobot 388 window cleaner 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, actually it’s designed for rectangular windows only.

Is there a limitation to the height and width of the window it can clean? 

This robot can clean only as far as its cords permit, but you can extend these cords. It comes with a 5-meter long power cord and a 4.5-meter long safety cord. For the safety cord, 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.

Final thoughts on the Hobot 388

Clean windows make a home attractive and healthy but keeping them that way can be an overwhelming task. And so is choosing the right robotic window cleaning for your home. 

With the sheer number of window cleaning robots available, picking the right one for you becomes a task of its own. But armed with this comprehensive Hobot 388 Review, you can better match your needs with the features of the gadget and make an informed decision.

If you have large rectangular windows and you want an efficient cleaning gadget to take on the task of always keeping them pristine and spotless, then you got your robot.
