Navimow i105N vs i110N Which to Buy: Simple 2026 Guide

7 min read by Tyler Novak Updated November 11, 2026

Navimow i105N vs i110N which to buy: the i110N if your lawn is close to a quarter acre. Navimow rates the i105N for lawns up to 1/8 acre and the i110N for lawns up to 1/4 acre. The i110N also has the longer battery runtime on the one comparison page that lists it, so it is the better fit for larger or more complicated yards. If your lawn is near 1/8 acre, the i105N is the simpler choice, and the lower-cost model is hard to beat for a small, open yard.

The short answer

Lawn size decides it. The i105N is rated for up to 1/8 acre (about 5,445 sq ft). The i110N is rated for up to 1/4 acre (about 10,890 sq ft).
Same core hardware. Both list the same cutting height, cutting width, navigation features, connectivity and 3-year warranty.
Battery is the open question. One comparison page lists 60 minutes for the i105N and 120 minutes for the i110N. We could not confirm that on a full manufacturer table.
Pick the smaller model only if your lawn is clearly under the i105N rating and you do not need extra runtime.

Most of the spec sheet is identical. Both models list a cutting height range of 2 to 3.6 inches (51 to 91 mm) and a cutting width of 7.1 inches (18 cm). Neither needs a perimeter wire, because both rely on RTK positioning to know where they are. Both also add AI vision obstacle avoidance, multi-zone mapping and no-go zones, which are the features that matter most once a yard has beds, trees or a play area.

Connectivity is also the same on both: 2.4 GHz Wi-Fi, Bluetooth and a 4G cellular connection. GPS tracking is not part of the base package and needs the Navimow Access+ 4G module, according to the same comparison page. Both models carry a 3-year warranty on that list.

Because these shared specs are the same, the choice rarely turns on the blade or the app. It turns on the lawn you have and how long the mower can work before it returns to charge.

Navimow i105N vs i110N: which to buy by lawn size

The rated lawn size is the clearest split between the two models, and robot mower coverage ratings are a starting point rather than a guarantee. Navimow rates the i105N for lawns up to 1/8 acre and the i110N for lawns up to 1/4 acre. A TopTenReviews review of the i105N gives the same 1/8 acre figure and notes that the i110N handles up to 1/4 acre.

Those ratings are useful only if you know your lawn area. An eighth of an acre is about 5,445 square feet, and a quarter acre is about 10,890 square feet. Measure the grass only, subtracting the house footprint, beds, patios and pools, because the mower cannot cut under them; our guide shows how to measure yard square footage. If your measured area sits close to the top of the i105N rating, the i110N gives you room to spare rather than running at the limit every day.

Our reading is that a yard well under 1/8 acre is where the i105N makes the most sense. Once you move toward the 1/4 acre rating, the i110N is the safer choice, because a mower rated close to your lawn size leaves less margin for slow spots. That margin is the practical core of navimow i105n vs i110n which to buy.

Battery runtime: check before you decide

Battery runtime is one of the main things to check when you weigh navimow i105n vs i110n which to buy. It is where the two models differ most on paper, and it is also where the sources disagree. A smarthomecompared comparison page lists a battery life of 60 minutes for the i105N and 120 minutes for the i110N. Another review page says the two models share the same battery, so we cannot give a confirmed number from the manufacturer alone.

Heads up

Treat the 60 and 120 minute figures as unconfirmed until you see them on Navimow’s own spec table for your region. Battery life also depends on grass height, slope, wet grass and how much of the yard is spread across zones, so a single number will not tell you how long a full mowing cycle takes (our guide to robot mower battery life explains the factors).

The practical question is whether one charge covers your lawn. If the mower needs to return to its dock and charge in the middle of a session, the time spent charging adds to the total time it takes to finish. A longer runtime matters more on larger lawns and on yards where the mower has to recharge several times a week.

Both models use RTK positioning (how RTK robot mowers work), which means they need a clear view of the sky for accurate navigation. Under tree cover or next to tall walls, positioning can drift, so the mower will only be as reliable as the spot where you place its base. AI vision obstacle avoidance helps the mower stop for objects such as toys or garden hoses, but it does not replace a clear, tidy lawn.

Connectivity matters if you want to track the mower away from home. Both models list 4G cellular, but GPS tracking requires the Navimow Access+ 4G module. Without that module, you still control the mower through the app over Wi-Fi or Bluetooth, which is enough for most owners who are at home.

Who each model suits

Here is the short version of navimow i105n vs i110n which to buy. This section is our reading of the specs above, not a test of either mower. Pick the i105N if your lawn is clearly under 1/8 acre, you want the lower-cost model, and a 60-minute runtime is enough for your schedule. Pick the i110N if your lawn is closer to 1/4 acre, you have a complicated layout with several zones, or you want the longer runtime that one source lists for it.

If neither fits, see these Navimow alternatives for other models to weigh. In either case, check that the rated area and battery life match your own measurements before you buy. A mower sized to your actual lawn with a comfortable margin will serve you better than a model that just fits on paper.

Frequently asked questions

Which is better, the Navimow i105N or i110N?

Neither is better in general. For navimow i105n vs i110n which to buy, the i110N suits lawns up to 1/4 acre and the i105N suits lawns up to 1/8 acre. Measure your lawn first, then choose the model whose rating matches it with some margin.

Does the i110N have a longer battery life than the i105N?

One comparison page lists 120 minutes for the i110N and 60 minutes for the i105N. Another review says the battery is the same on both models, so confirm the runtime on the manufacturer’s spec table before you buy.

Do both models need a perimeter wire?

No. Both are listed as wire-free models that use RTK positioning for navigation, with no perimeter wire to install. Setup still requires placing the base and defining zones in the app.

Do I need the 4G module to use either mower?

No. The mower works through the app over Wi-Fi or Bluetooth. GPS tracking is the feature that requires the Navimow Access+ 4G module, according to the comparison page we read.
