Today’s robot lawn mowers are better than ever, with superior, often wire-free navigation and the ability to tackle more complex yards. The downside is that the best robot lawnmowers can cost you anywhere between $1,000 to $3,000, with top-tier models going for as much as $5,000.
That’s what makes Volta‘s “Robot-as-a-Service” model so interesting. Instead of buying the robot mower outright, you lease it via a monthly subscription fee until you’ve fully paid it off, at which point you can choose to continue paying a lower subscription rate for remote functionality or halt the subscription entirely.
If you’re subscription-weary, this may not be appealing, but as someone who didn’t want to spend thousands on a robot lawnmower that couldn’t handle my large, complex lawn, I found it made sense. I deployed the Volta in a real-world setting to see if subscription robot lawn care is the wave of the future or an unfortunate blip.
What is Volta?
The Volta lawn mower mowing circles on my lawn. The pattern is a little erratic, but it gets the job done.
The Volta Smart Robot Lawn Mower or, more cheekily, the Volta Lawn Companion, is a compact, AI-driven mower that relies on Global Navigation Satellite System and built-in sensors to navigate your lawn. The company emphasizes that the system doesn’t requires any cumbersome buried wires, antennas or other boundary markers to guide the bot, which is designed to learn and evolve with each mowing session on your property.
This isn’t necessarily groundbreaking; many of our top picks tested at CNET now support LiDAR navigation, vision or wireless RTK to help you cut the cord. However, in Volta’s case, the system is iterative. Instead of one major mowing session each week, the robot makes a series of smaller, frequent passes to keep your lawn exquisitely trimmed without building up excessive grass clippings. Volta’s Lawn Intelligence system will gather data about your lawn’s grass, terrain and microclimates over time and learn how your lawn responds to rain, heat, shade and mowing patterns, then automatically refine its behavior in response.
That’s all a long-winded way of saying that it’s using AI to improve mowing over time, which is what a lot of robot lawn mower manufacturers are doing these days. The key that makes or breaks them is how well this works in practice, which is what I set out to test.
How the Volta subscription model works
The Volta comes with three different subscription tiers, or you can buy it outright.
Unlike other robot mowers, you don’t buy the Volta outright. Instead, a 24-month commitment is required, after which you fully own the robot. However, to keep all AI features in the Lawn Intelligence platform, you’ll need to keep paying a (reduced) monthly subscription thereafter.
The subscription model is broken into three tiers:
Basic
-
$72/month during the 24-month commitment.
-
It includes core AI learning, standard mowing schedules, weekly path optimization, basic lawn health insights, GNSS Basic positioning, and monitoring.
-
After 24 months, the price drops to $16/month for continued Basic service.
Ultra (the company says this is the most popular tier)
-
$89/month during the 24-month commitment.
-
Ultra includes remote AI learning, real-time path optimization, AI-powered Q&A called “Lawn Chat,” personalized lawn reports, Digital Twin lawn modeling, GNSS Ultra with anti-theft GPS and weather-adaptive optimization.
-
After 24 months, the price drops to $59/month.
Elite
-
$159/month during the 24-month commitment.
-
Covers up to half an acre, supports two robots and two charging stations, multi-robot coordination, VIP support and advanced features.
-
After 24 months, the price drops to $99/month.
Traditional robot lawn mowers require a single upfront purchase of the hardware, typically between $1,000 and $5,000, depending on the model.
Compare this to Volta’s hardware totals: at the Basic tier, you’ll pay $1,728 before fully owning the mower, up to $3,816 at the Elite tier. While you’ll pay less upfront and in smaller increments, you’re not getting an overall discount by choosing the subscription route over other manufacturers.
Warranty support
The Volta is one of the more compact robot lawn mowers in terms of dimensions, about the size of the Eufy E15.
Volta offers ongoing customer support through remote help and email, plus local dealer assistance for installation, battery work and repairs. It also says confirmed defects are replaced or reshipped at no extra cost. Higher-tier Ultra plans add “Infinite Care” full-unit replacement as long as the service stays active. The company also bundles 24 months of Lawn Intelligence service with the mower, after which the service can be renewed at reduced rates or the mower can continue in autonomous-only mode, so it does involve an active service commitment for the full feature set rather than just a one-time purchase.
Compared with a standard manufacturer’s warranty, the big advantage is that Volta combines warranty coverage with service, remote diagnostics and — in some cases — replacement coverage that extends beyond basic defect repair. The downside is that many of those benefits depend on keeping the service active, making it more of a hardware-plus-service package than a traditional warranty alone.
Using the Volta
With its onboard sensors and AI, the Volta should get smarter and more familiar with your yard over time.
I began testing Volta in a small subsection of my lawn where the terrain is relatively flat and there are few obstacles, and slowly expanded its area of operation over several days, experimenting with its scheduling features and other options. My lawn is large and complex, with lots of bushes and trees, raised beds, other obstacles and uneven terrain, including several (fairly gentle) slopes. Taken as a whole, it comes in at around 17,000 square feet.
Setup wasn’t as easy as I hoped
The setup for the Volta wasn’t as simple as I would have liked. But once I got over the hump, it was up and running.
First, let’s start with the Volta App. The setup was immediately problematic when the QR code provided with my mower led to a dead link. This, it turns out, was emblematic of an issue plaguing the entire app, which is riddled with dead links. For instance, the “Chat with Us” option under support returns a baffling “Oops: There was an issue with launching WhatsApp” error. And the link to data about your account from the Service and Warranty page returns a 404 error, for example. I also had issues getting the app to connect to my Volta and the Volta to connect to Wi-Fi during the initial setup phase, which led me to restart the process multiple times.
Wi-Fi connectivity, it turns out, is absolutely essential for the Volta to perform properly. I have a large lawn, and initially the base was in an area not covered by my network. Attempting to run it under those conditions made the bot unusable: It mowed erratically, sometimes circling the same patch of grass interminably or stopping at random spots far from the dock. To resolve the issue, I had to install a Wi-Fi extender and ensure the base was fully within the network coverage.
After the Wi-Fi issue was resolved, however, the bot performed fairly well. It attaches to a small charging dock that you place somewhere in your lawn, and despite my initial misgivings about leaving the entire apparatus exposed to the elements, it’s proven very durable, despite heavy rain on several days after installing it.
The weather can complicate things
Volta doesn’t have a manual mode, so you’re relying on its AI smarts to mow your lawn without missing spots.
However, the rain presented a separate issue. It led to several areas of my lawn being quite sodden, and even to some standing water. In fairness, the Volta marketing materials are clear that the bot is intended for well-kempt lawns that are relatively simple and flat, and indicate that it will struggle in rough terrain. While it avoided areas of standing water, it also steered clear of softer sections of the lawn that should still have been serviceable, sometimes in erratic patterns that didn’t seem to match the moisture levels.
However, the bot did a very solid job of avoiding obstacles such as tree trunks, a wood pile behind my home, bushes and shrubs and my large driveway. There were two occasions when it bumped into the side of the house and seemed unable to extricate itself, forcing me to shut it down and manually return it to the dock.
These issues are particularly worrisome because the Volta lacks a manual control mode. You have to trust the bot’s AI navigation entirely and allow it to operate completely autonomously, which is frustrating when you watch it fail to deal with issues in real time, or want to give it more specific guidance about which parts of an area belong to you and where the neighbor’s lawn begins.
Quiet, consistent performance and solid obstacle avoidance
Obstacle avoidance is quite good, even if its pattern seems erratic.
On the upside, the Volta is incredibly quiet; beyond a few yards, you can barely make out the sound of its motor or blades. It’s also lightweight and seems fairly rugged, though it won’t reach speeds where collisions would pose much of a threat to the chassis.
After resolving the Wi-Fi issue, the mower did an excellent job of avoiding large obstacles including the walls of buildings, and with the “Edge Precision” setting enabled, it mowed very snugly along the perimeter of those obstacles.
Its mowing patterns are pretty erratic; instead of just consecutive vertical or horizontal passes, it often moves diagonally, sometimes seemingly without any obvious reason. That said, while the individual strips it mows are quite narrow, it does a thorough job of evenly cutting the entire assigned area. The grass looks trim and neat afterward, and there’s no real visual evidence of how erratically it maneuvers.
Is the Volta Smart Robot Lawn Mower worth renting?
The subscription model may make sense if you aren’t sure if a robot lawn mower can handle your yard.
For smaller, simpler yards, I’d recommend the Volta, particularly since you could probably get away with the Basic tier without missing many of the advanced features in the more expensive offerings. Even if your lawn has a fair number of larger obstacles, I think the Volta is a good fit in this scenario, as long as you give it a good initial trim before you start the Volta’s regular maintenance schedule.
However, for any larger lawn with a lot of irregular terrain, rough or sandy areas, sharp changes in elevation or other challenges, you’re better off with a robot mower with more manual control options — or one that’s better suited to difficult terrain. While the Volta’s AI features are reasonably impressive, no amount of learning can overcome its small, low-profile, low-torque frame. Also, if you’re unable to ensure that at least the base of the unit is fully covered by reliable Wi-Fi, the Volta isn’t the mower for you.
Buying vs. renting a robot lawn mower
The wire-free navigation is a big selling point for the Volta, but there are now many models that have the same capability.
How the price shakes out depends largely on which subscription model you choose, but the Volta generally compares pretty well to competitors including the Eufy E15 or the Ecovacs GoBot A3000 in terms of capabilities and features. All three models offer wireless navigation and generally similar smart features and capabilities.
If you eschew the long-term subscription model for the Volta and just pay cash upfront, the lowest tier is $999 after the discount; the mid-tier option is $1,299; and the highest tier is $2,299.
By contrast, the Eufy E15 is usually $2,300 (currently on sale for just $1,000), while the Goat A3000 is $3,000. The Goat A3000 might be a slightly better choice for lumpier yards, while the Eufy model may be a better option if you’re obsessed with presentation and want clean, parallel lines.
However, in my experience with the Volta, it performs well in the type of lawn and environment it was designed to handle, and can be had for less if you’re willing to sacrifice some of its advanced features. Ultimately, if you’re uncertain about whether a robot lawn mower can handle your lawn, the Volta isn’t a bad way to take one for a test drive without a commitment. But in the long run, with the subscription fees tacked on, you’ll eventually be spending more on the Volta after 24 months than you would just buying a similar device such as the Eufy E15 up front — especially when it’s substantially discounted at the moment.
