Best Hookii Robot Mower Model to Buy: 3 Models Compared

8 min read by Megan Hartley Updated November 11, 2026

The best Hookii robot mower model to buy depends on your lawn size and how steep the yard is, and only two Hookii models have brand spec pages we could read. The Neomow X and Neomow X Pro are listed on Hookii’s own site with a 24-degree (about 45%) slope limit and LiDAR navigation with no perimeter wire. The Neomow X SE appears only in a retailer listing, so its figures stay unconfirmed. This guide sets out what each source says and what to verify before you order.

The short answer

Smaller lawn, up to about 0.74 acre: the Neomow X, which Hookii’s page recommends for 3,000 m² (0.74 acre).
Larger lawn, up to about 1.24 acres: the Neomow X Pro, recommended for 5,000 m² (1.24 acres), with a larger 315 Wh battery.
Neomow X SE: a retailer lists it at up to 0.75 acre with 4G connectivity, but no official slope rating was found.
Steep yard: both brand-listed models carry a 24-degree (about 45%) slope limit. Our reading is to test your steepest section before relying on that number.
Boundary wire: the X and X Pro navigate with LiDAR SLAM, with no perimeter wire and no RTK or UWB base station.

Best Hookii robot mower model to buy: the models compared by source

Only two Hookii models appear on the brand’s own spec page, so the table below keeps brand figures apart from retailer figures.

Model	Rated area	Max slope	Cutting width	Battery and mowing time	Source
Neomow X	3,000 m² recommended (0.74 acre); the navigation menu says up to 4,000 m²	24° (about 45%)	280 mm (11 in)	13 Ah, 234 Wh; 120 min mowing per charge	Hookii EU new-release page
Neomow X Pro	5,000 m² recommended (1.24 acres); the navigation menu says up to 6,000 m²	24° (about 45%)	280 mm (11 in)	17.5 Ah, 315 Wh; 180 min mowing per charge	Hookii EU new-release page
Neomow X SE	Up to 0.75 acre (32,670 sq ft)	Not officially rated	11 in	Not listed	Retailer listing only; the brand SE page could not be read

Hookii’s page gives a 30 to 85 mm cutting height for both the X and the X Pro, and a 180-minute charge time for each. The retailer lists the SE at 38.5 lb and says it connects over 4G with app control.

Hookii sells other models, and a search result named a Lite and an S. We could not open a brand page for either, so this guide leaves them out rather than guess their specs.

Start with rated area, then subtract what you will not mow

A rated area is a ceiling, not a guarantee, and it is the first filter for the best Hookii robot mower model to buy. If your lawn is nearer 1.5 acres, what size robot mower a 1.5-acre lawn needs gives wider context. Measure the grass you will actually cut, then subtract beds, patios and areas under trees you will not mow. Coverage ratings usually describe the total area kept trimmed within a growth cycle, and they assume a flat lawn, according to Eufy’s explainer on robot mower coverage. Obstacles and slope both reduce the real figure.

The Hookii page gives two numbers for each model, and they conflict. The navigation menu says 4,000 m² for the X and 6,000 m² for the X Pro, while the spec table recommends 3,000 m² and 5,000 m². Our reading is to size by the spec-table figure, because it is the one tied to a specific recommendation, and to leave margin above it.

Wire-free LiDAR or boundary wire

Both brand-listed models navigate without a perimeter wire, which changes setup and repair. If you are still deciding how mowers find their way, wire-free versus boundary wire robot mowers sets out the trade-offs. LiDAR builds a map during a mapping pass and supports no-go zones (see how a LiDAR robot mower works), as Resident’s explainer on LiDAR mowers describes it. Hookii also says the X and X Pro need no RTK or UWB base station, and its page mentions vision sensors for detecting small animals.

A wired mower depends on one continuous loop. Robomow’s guide to boundary wires notes that a break is hard to locate, especially when the wire is buried. Mammotion’s guide to boundary wires also says one wire fault can stop a wired mower completely. Those are vendor statements, but they describe the same failure point. A wire-free design removes it, though it does not remove the need for clean mapping and sensor care.

What the 45% slope limit means

Slope is usually given as a percent grade, which is 100 times the tangent of the angle. A 45-degree slope is 100%, so 24 degrees works out to about 44.5%, which Hookii’s page lists as 45%. The grade formula is simple, but the practical limit is what matters.

Eufy’s slope guidance treats a rated maximum as an absolute limit. It says running at the top of the incline strains the motor, and that wet grass reduces tire grip even within the rated limit. Hookii’s pages do not include those caveats, so read them as general guidance from another brand, not as Hookii specifications.

The SE has no official slope rating. The retailer says it is “not officially rated”, so ask the seller in writing before you assume a hill is safe. For the general idea behind these numbers, see robot mower slope rating explained.

Cutting width, height and battery

The X and X Pro share the same 280 mm cutting width and 30 to 85 mm cutting height. The difference is the battery. The X carries 13 Ah (234 Wh) and gives 120 minutes of mowing per charge. The X Pro carries 17.5 Ah (315 Wh) and gives 180 minutes. Both take 180 minutes to charge.

Our reading is that mowing time per charge matters more than the battery label. If your lawn sits near the rated area, the X Pro gives more margin for the same lawn.

Who each option suits

Our reading, based only on the published figures, is that the best Hookii robot mower model to buy for most lawns is the one whose rated area leaves margin. The Neomow X suits a lawn at or below about 0.74 acre with a flat to moderate slope and no need for extra runtime. The X Pro suits a larger lawn, or a yard you want to cover in one charge with margin. The SE suits buyers who accept a retailer’s rated area and want 4G app control, provided they confirm the slope and warranty terms first.

What to check before you buy

Confirm the exact model name. The best Hookii robot mower model to buy is the one that matches your lawn, so check the name first. Retailers list several Neomow X variants with different rated areas, so match the name to Hookii’s own page.
Measure the usable lawn. Subtract beds, patios and trees, then compare against the spec-table figure, not the navigation-menu figure.
Measure the steepest section. Use a phone inclinometer app and compare the reading with the 24-degree limit, leaving margin for wet grass.
Ask the seller about the SE in writing. Get the slope rating, cutting height and warranty terms before ordering.
Check warranty and support terms. Read them before buying, not after the first fault.

Parts and upkeep

Blade changes use small fasteners and a hex tool. Confirm the fastener size and blade part number in the manual for your exact model before you buy tools or spares, because the parts can differ between models. The steps are the same in principle as how to change robot mower blades.

Frequently asked questions

Which Hookii robot mower model should I buy for a large lawn?

On Hookii’s own page, the Neomow X Pro is recommended for 5,000 m² (1.24 acres), against 3,000 m² (0.74 acre) for the Neomow X. Size by the recommended figure, not the higher navigation-menu number.

Do Hookii Neomow X models need a boundary wire?

No. Hookii’s page says the X and X Pro use LiDAR SLAM with no perimeter wire and no RTK or UWB base station.

Can a Hookii mower climb a 45% slope?

The X and X Pro are listed at 24 degrees, about 45%. That is an absolute limit, and wet grass reduces grip. The SE has no official slope rating, so ask the seller before assuming a hill is safe.

Is the Neomow X SE worth buying?

The published figures cannot settle that alone. The SE’s retailer listing gives a 0.75-acre rating, 11-inch cutting width and 4G app control, but no official slope rating. Compare those with your lawn and get the warranty terms in writing.
