The catch
ANTHBOT M5
The shorter cycle restricts how much it can do before the lawn is wanted for something else.
Side by side
M9 is the choice if the lawn is bigger than M5’s 500 m² rating or you need a longer uninterrupted mowing window. M5 is the choice for a smaller lawn with flexible mowing hours and a worthwhile saving. Battery and capacity go up, while deck width and cutting heights stay the same.
Before you buy
From a full charge, M9’s claimed run could cover the entire window. M5 hits its stated recharge point at 40 minutes and then needs 60 minutes to charge, so about 50 minutes of the free-lawn window are spent charging. Actual runtimes will shift with grass and terrain.
Where this comes from
ANTHBOT M5: 40-minute run, 60-minute charge. ANTHBOT M9: 90-minute run, 90-minute charge. Example assumes a fully charged start.
The catch
The shorter cycle restricts how much it can do before the lawn is wanted for something else.
The catch
Neither the deck width nor the cutting-height ceiling grows with a bigger battery.

ANTHBOT M5 vs M9 for a divided small yard. Look at charging pauses, carrying weight and zone allowance, and don't mistake battery size for cutting width.
Which one fits
The rated area is met by M9 alone.
M5 may do the job, while M9 mainly adds cycle headroom.
The M9 states the longer continuous run, though finishing is not guaranteed.
The ceiling is equally low on both.
In practice

The M9 is just 0.3 kg heavier and its body dimensions are the same. Moving it between isolated sections means about 10.6 ounces extra. Supporting multiple mapped zones does not give either mower the ability to cross steps.
ANTHBOT M5: 9.8 kg, 49.8 by 39.2 by 25.1 cm. ANTHBOT M9: 10.1 kg with the same dimensions. 0.3 × 35.274 = 10.58 ounces.
A 70 mm ceiling and a 20 cm deck are shared by both, so a three-inch mowing target rules out both. On a lawn that fits both area ratings, M9 gets you longer between charges and more zones, but no taller cut and no wider strip per pass.
ANTHBOT M5: 20 cm deck and 70 mm maximum height. ANTHBOT M9: Same deck and height. Three inches equals 76.2 mm.
Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
Its rating covers 0.125 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Its rating covers 0.25 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.

Spec by spec
| Spec | ANTHBOT M5 | ANTHBOT M9 | In practice |
|---|---|---|---|
| Area rating | 500 m² | 1,000 m² | Measure the grass you maintain. Leave out the rest of the lot. |
| Mowing and charging claims | 40 and 60 minutes | 90 and 90 minutes | Run time can matter more than recharge time. |
| Battery | 45Wh | 90Wh | Having twice the energy does not mean twice the daily output. |
| Cutting hardware | 20 cm deck, 30 to 70 mm height | 20 cm deck, 30 to 70 mm height | Strip width and grass-height limits stay the same after the upgrade. |
| Weight and zones | 9.8 kg, twenty zones | 10.1 kg, thirty zones | Stepping up to the bigger battery adds little weight to carry. |
Trade-offs
Change of plan
Go with ANTHBOT M5. Scheduling charging pauses is easy
Go with ANTHBOT M9. The mower needs to run longer before the lawn is in use
