HART 40V Cordless Mower vs. Bosch Robotic Lawnmower: What’s the Difference?

These are clearly two very different lawnmowers, but both models can help you maintain a well-cut lawn. To help you decide which mower will suit your lifestyle, here are the key differences between the HART 40V cordless mower and the Bosch Robotic Lawnmower:

Lawnmower Type

This is the fundamental difference between the two types of mowers. The Bosch robotic mower is a fully automated mowing device that doesn’t require any human control. Once correctly set up, it automatically runs through a scheduled mowing cycle, zigzagging across your lawn until it has trimmed your lawn to a level height. 

A self-propelling mower like the HART mower is an upright mower that automatically moves. Rather than pushing this lawnmower, you simply steer it while it moves forward at a speed of up to 3 MPH. 

Form Factor

The HART mower has a conventional upright design that folds down for compact storage. The Bosch robot is much smaller, operates close to the ground, and has a compact footprint. 

Cutting Radius, Cutting Height, and Maximum Mowing Area

The smaller robotic mower has a cutting radius of just 7.4 inches, just over a third of the HART self-propelling mower’s. Its maximum cutting height is half that of the HART lawnmower. This is because the robotic mower works completely differently from a conventional lawnmower. Rather than cutting the entire lawn quickly in one sitting, robotic mowers cut grass on an automatic schedule designed to cover your entire lawn over several hours or days. Rather than heavily mowing the lawn, a robotic mower moves through sequential mowing cycles over the week to keep the lawn trimmed to a preset height.

Additional Requirements

Robotic mowers use a buried perimeter wire to navigate when cutting grass. The perimeter wire works similarly to a wireless electric dog fence, sending a signal that tells the mower to change direction. If you buy this mower, you will need to install this wire, which can be tricky but is essential for the robot to cut grass properly. 

Additional Features

The HART self-propelling mower handles clippings in a regular way. This lawnmower comes with a 2-bushel bag that will automatically fill as you mow. You can then conveniently bag or discharge clippings wherever you want. The 3-in-1 function of this mower includes a mulching setting that will distribute the clipped grass as a mulch for your lawn. 

The Bosch mower does not have a bag for collecting grass clippings. Instead, this mower cuts the trimmed grass into a fine mulch that coats and fertilizes the lawn. The action of the robot as it moves across the lawn naturally spreads the mulch.

Charging

Bosch robotic lawnmower carries an integrated battery that does not have to be removed for charging. Instead, the robot will automatically return to a supplied charging station, where it docks for charging. When the battery is full, the mower leaves the charging station and resumes its mowing cycle. 

The HART mower carries two 40V, 6.0Ah removable batteries that sit in a dedicated bay on top of the mowing deck. Once you have finished using this cordless mower, simply remove the batteries and place them in their charger to ensure that they are fully charged. 

Warranty

HART provides a 5-year manufacturer’s warranty for its mower and a 3-year warranty for the batteries, while Bosch offers a 3-year warranty for its robotic mowers. 

What You Need to Know About the Hart 40V Cordless Mower

HART is a subsidiary of Techtronic Industries Company Limited (TTI Group), a power tool company from Hong Kong. HART designed the 40V Supercharge Brushless 21-inch self-propelled mower to deliver maximum convenience and ease of use, making cutting your lawn a quick and easy task. Though you have to steer the mower via its foldable handle, the HART mower’s self-drive function and powerful cutting action mean that you won’t have to exert yourself. The cordless function also means that there’s no gas, oil, or pull cord needed, and you won’t have the noise and exhaust of a gas mower.

Advanced battery technology

Proprietary 40V lithium-ion batteries power the HART mower. In this case, they supply enough power to cut almost ¾ of an acre from a single charge. HART batteries use Supercharge technology to charge these batteries quickly. 

3-in-1 Management of grass clippings

The 3-in-1 function of this mower means you can choose to bag mulch or discharge your grass clippings. If you’re keen to compost cut grass, this mower comes with a collapsible bag and frame that has a capacity of 2 bushels and offers hands-free side discharge of grass when you’ve finished mowing. 

Easy, intuitive handling 

Hart designed the 40V cordless mower for ease of use. As such, aside from the push-button start, this mower features a knob to adjust cutting height, FAST FOLD handles, and even integrated LED headlights so you can mow in low light. In addition, when you’re done with using the mower, it folds down completely for easy transportation and storage.

What you need to know about the Bosch robotic mower 

Bosch is a German engineering and technology company that is known for the quality of its power tools and garden equipment. The Indego M+ 700 robotic mower is a smart device that can be programmed to intelligently and automatically cut your lawn. 

Precision cutting for a perfect lawn

Bosch’s Indego M+ 700 is ideal for small and medium-sized gardens with single or multiple lawn areas of up to 700m² in size. The robot uses an algorithm to calculate the most efficient route for getting the lawn cut in a reasonable time. Further, the robot cuts efficiently and intelligently, with BorderCut technology to ensure that the edges of your lawn stay neat. Other features include a MultiArea setting for multiple lawn covered areas along with a setting for cutting narrow passages. 

App-controlled lawn mowing 

Though you don’t have to physically mow the lawn with a robot in your yard, you do have to program and control the robot, so that it maintains a suitable cutting schedule. However, you can do this via the super-convenient Smart Gardening app that can link your Bosch robotic lawnmower to Google or Amazon devices. In addition, the mower can even use the latest weather forecast to decide if conditions are suitable for mowing. 

HART 40V Cordless Mower vs. Bosch Robotic Lawnmower: Must-Know Facts

  • Robot mowers require some handling for setting the cutting height and cleaning and repair of the mower’s blades.
  • The HART mower has two blades, while the Bosch mower comes with three small blades on its rotating disc. 
  • If the perimeter wire of the Bosch robotic mower gets cut or disconnected for any reason, the robot will not work. 
  • Both the Bosch and HART mowers have brushless motors.
  • According to HART, the HART 40V cordless mower can outperform a 163cc gas mower.
  • You can only charge HART mower batteries on the dedicated 40W rapid charger.
  • The composite deck of the HART mower is weatherproof and resists dust ingress.  

HART 40V Cordless Mower vs. Bosch Robotic Lawnmower: Which One Is Better? Which One Should You Use?

This is a tough decision. Both mowers make it extremely easy to maintain your lawn, but they work in completely different ways. Sure, the robot delivers hands-free mowing, but it requires the setup of a perimeter wire, which may be a hassle or require the expense of professional installation. 

The HART mower is self-driving but still needs your hands to guide it around the garden. It is obviously the more powerful choice and cuts much more grass, but you’ll be walking behind it. 

If you have a small yard that you want to keep low maintenance, the robot is a decent investment as once you set everything up, the only reason you’ll have to handle it is to make adjustments or troubleshoot problems. However, for a bigger lawn, the Hart mower wins hands down as it is powerful, easy to use, and stores compactly.

Technology Updates to the HART 40V Cordless and Bosch Robotic Lawn Mowers

Both the HART 40V and Bosch robotic lawn mowers have received technology updates that keep evolving the designs for consumer demands.

Among the number of updates to the Bosch Robotic lawn mower is a new built-in weather sensor that adjusts the mowing schedule based on outside forecasts. This mower also has a new damage-resistant metal casing, and an improved navigation system for better direction while automated mowing.

With their new 40V cordless mower, HART has included many new updates. For convenience, the lawn mower now has a 2-in-1 mulching and bagging process that collects the grass clippings, so that owners can now cleanly collect the debris and turn it into mulch. The 40V mower is also now more technologically-enabled, with a voice assistant and a Smart Hub where owners can control it entirely through Wi-Fi to view the mower’s status, set a cutting schedule, and change the clipping height.

Final Thoughts

These two mowers lead their respective markets for performance and value for money, but only Bosch offers the opportunity for completely hands-free mowing. Certainly, robot mowers are a new concept to many people, but this technology is only increasing in prevalence and may eventually overtake more conventional models like the Hart mower.

Looking Ahead to 2024

Bosch and HART are both frontrunners in terms of popularity and technological development for lawn mowers. While their next models or specific improvements have yet to be announced, here are a few updates that we may see next year or beyond as both manufacturers continue to produce top-of-the-line lawn mowers:

  • Improved smart technology and AI integration: It is expected that both brands (and their other competitors) will continue developing how the lawn mowers can interact and synch with other smart home devices. AI is also becoming more prevalent in the day-to-day lives of consumers, which will most likely be a future focus for technological development.
  • Battery improvements: HART’s 40V lithium-ion battery is already incredibly powerful, but as better-performing batteries continue to inevitably develop we can expect to see HART and other producers use them. For Bosch’s line of robotic lawn mowers, it is also possible in the future that the mowers could develop the ability to be entirely self-sufficient for charging.
  • Affordability: With the continued improvement of technology, there will be more choices available to consumers to choose a lawn mower. This increased competition may drive down prices and make automated or cordless lawn mowers more affordable for buyers.

Frequently Asked Questions

What is a brushless mower?

A brushless motor is a type of electrical motor that lacks mechanical commutators (brushes). The brushes generate heat and friction in a brushed motor, making it inefficient. By adopting a brushless motor, these mowers increase their energy efficiency and extend battery life so they can cut grass for longer.

Can a robotic mower work in the rain?

Yes. The body of the robotic lawnmower is made of waterproof composite material and its electronic components are sealed from moisture and dust ingress. It will automatically mow the grass in rainy weather unless you program it to skip mowing on rainy days. The mower can also update and amend its schedule if the expected weather is severe.

Can you secure a robot mower from being stolen?

Yes. Most robot mowers will automatically shut off if picked up or removed from their mowing area. You can secure the control panel of the robot mower with a 4-digit PIN and some models have GPS tracking.

Is the Bosch robotic mower battery replaceable?

Yes, you can purchase replacement batteries from Bosch. Their robot mower batteries typically last between 2 and 6 years.

Can I use OEM Li-ion batteries with the HART mower?

HART recommends that you only use HART-branded batteries and chargers. Using different batteries is likely to invalidate the lawnmower’s warranty.
