Advanced Window Cleaning Robot
HOBOT 298The Hobot 298 window cleaning robot is an advanced robot with the ability to clean large windows with ease. A removable water tank and spraying nozzle make for a more user friendly design, as compared to older Hobot window cleaning robots. With a square design, this Hobot covers more surface area with every pass. The large cleaning pad located on the bottom of the Hobot 298 works to agitate, lift, and remove dirt, grime, and other substances off of your glass. Especially good for hard to clean windows. Overall cleaning performance is good, but much better when window cleaner is applied.Check Price

Each of these items are labeled clearly on the Hobot 298, making it easy for the user to understand what is what when operating the 298.
Bottom of the Hobot
Once flipped over, the bottom of this Hobot is fairly simple. There are two tank-like wheels, several velcro pads (used for attaching the cleaning pad), and an aerated oval.
The holes on the bottom are used to create suction onto the window you are cleaning.
Aesthetically speaking, the Hobot 298 has a cool look.
An all white color scheme, square shape, and sharp edges give it a more modern feel.

Hobot 298 Features
The Hobot 298 has taken a step up from the previous Hobot window cleaning robots, with regard to features.
Probably the most notable feature about the Hobot 298 window cleaning robot is its spray nozzle. Most of the window cleaning robots require users to wet the pad before putting the unit to work.
The Hobot 298 works by spraying the window as it cleans.
Included with the Hobot 298 is an extension cord, which is virtually essential to cleaning windows of any size.
The extension cord of ~20 feet long.
If you’re cleaning a large number of windows you may want to get an additional extension cord so you don’t have to keep finding close power plugs.
Wifi Connectivity & App control
The Hobot 298 has wifi connectivity, giving users the option of connecting their smartphone through the Hobot app.
The app allows users to:
- Control the exact movement of the 298
- Place the Hobot in three different directional cleaning modes
- Start and stop the robot
- Increase the amount of water / speed at which the Hobot 298 is ejecting and traveling
Performance on the Hobot 298 was interesting. We ran a couple of different tests to see which cleaning modes worked best and why.
The first test was a success, but not to the highest degree. After letting the Hobot 298 run up and down the sliding glass door, we saw the following:
- The Hobot was not able to reach the edges of the glass
- The dust outside was too thick for the Hobot to remove completely
- There were some streaks left on the glass
- The spray nozzle fires towards the lower third of the robot, meaning the top portion of the cleaning pad is not always using solution to clean
Although these were some of the flaws, there were some positive notes as we moved the Hobot 298 to the inside portion of the glass:
- Much better cleaning performance compared to previous Hobot we tested
- Basic light dirt, smudges, and fingerprints were removed easily
All in all, the cleaning performance from the first test was decent, but not overwhelmingly impressive.
The score for cleaning the outside portion of the glass was 80%, while the inside score was 94%.
Test #2 results
Once we moved onto the second test, we saw a much better cleaning performance. This test included spraying the glass (inside and outside) with a glass cleaner, followed by placing the 298 on the glass and letting it run a full cleaning cycle.
Our results were as follows:
- Hobot 298 glided across the glass and removed the vast majority of dust caked onto the glass
- Minimal streaks
- Cleaner sliding glass door without a doubt
- Did not seem to struggle staying fully attached to the window
In the end, we have found if you’re using the Hobot without any window cleaner sprayed onto the glass, it is best suited for indoor surfaces with easy-to-clean messes.
That said, for tough messes / caked on dirt, you’ll want to apply a bit of window cleaner to the window and/or to the Hobot pad itself to help improve performance.
Setup & Usability
Setting up and using the Hobot 298 is simple, from beginning to end. There are not many steps to setting up the robot, and using it is virtually a hands-free process.
How to Setup
In order to get the ball rolling, users have to set up the Hobot 298 by completing the following tasks:
- Remove all parts from the box
- Apply cleaning cloth to bottom of the unit
- Fill water tank
- Plug in
- Setup app (if desired)
If you want to control the 298 via the Hobot smartphone app, it does need to be connected.
To connect the app to the robot, users must download the app, turn on the robot, and voila! The app automatically connects itself to your Hobot.
Bear in mind, you will need to have bluetooth turned on in order to connect the two devices.
Using the Hobot 298
After getting everything setup, using the unit is as simple as popping it on your window and turning it on. From there, the Hobot 298 will begin cleaning for you.
Hobot 298 Maintenance
Maintenance on the Hobot 298 is of the utmost importance. For a unit like this, disregarding the maintenance will directly hinder the overall performance of the unit.
The most important areas to focus on are the wheels, laser sensors, water tank, and cleaning cloth.
Each of the wheels should be wiped down before every use, as should the two laser sensors.
With regard to the water tank and cleaning cloth, this is more or less dependent on how often the 298 is being used.
The more you use it, the more often the cleaning cloth should be changed (removed and washed) and the water tank should be refilled.
Is the Hobot 298 a good value?
In the end, the Hobot 298 is an okay value. The cleaning performance varied, depending on whether or not the cleaning solution was applied directly to the glass or added into the tank of the Hobot.
That said, the price is a bit high for the cleaning performance. Considering the price, I would have expected the Hobot 298 to clean well on its own, without having to manually apply cleaning solution to the glass.
On the other hand, if you’re okay with having to do a bit of the work on your own, the Hobot offers a solid value for those users who have larger windows, windows that are know for collecting dust frequently, or windows that are hard to reach.
Long story short, the Hobot 298 could be a good value, but it really depends on your home, expection levels, and how you plan to use it.
