Stiga robot mower slope: ponds, drops and 45 percent
Updated: October 2026
The title says 45%, the lawn falls toward a pond, and you need to know if the mower may follow it. A Stiga robot mower slope figure counts only when that ASIN prints it. Water and a drop still need a gap. This page stays with gradient, ponds, and edges. The rows are on the [Stiga lawn mower comparison](/hub/lawn-and-garden-equipment/stiga-lawn-mower). A purchase through those links can earn a commission at no extra cost to you.

45% is a rise of 45 cm in 100 cm
A 45% slope rises 45 cm for every 100 cm of horizontal ground. STIGA’s UK A 6v page writes the same limit as 45% (24°). The degree belongs to that page. It is not on every row that says 45%, and it is not a conversion to paste onto a listing with no percent. A wider look at gradient claims is in how steep a lawn mower can cut.
Three ASINs print 45%: the A 6v at about £949, the A 8v at about £1,299, and the 5 Ah A 15v at about £1,097.40. Only the A 6v page in this pass also writes 24°. The manual treats that percent as the work-area ceiling, 45% or 50% by model, and a steeper bank is excluded from the map.
Where this comparison is silent
The A 4, B0F5BSFCBG, at about £999, states up to 400 m² and no slope percent. You cannot give it the A 6v’s 45% because both are STIGA robots. If the bank is why you are buying, leave this row closed until a number appears on that ASIN.
The A 10v and A 15v garage-cover listings say challenging sloped terrain. They print no percent and no degree. Challenging is not 45% and not 24°. The plastic cover does not add a rating. Those prices are about £1,299.34 and about £1,466.38. Both collectors are silent too. The 132e and the 136e are push mowers for the flat patch reviews actually describe. Do not invent a pedestrian slope from the robot rows. Budget and stated area stay on the Stiga lawn mower buying guide.
Ponds, drops, and the edge
The manual says keep the virtual perimeter at least 1 metre from a pool, a pond, or an excavation, and off banks steeper than the model’s slope. That metre is a gap you draw. A UK dealer’s pond answer, updated in September 2026 and written about robots in general, says the boundary keeps the machine out of the water, and a wet slope can slide it past the line. Those examples are not STIGA measurements. The camera is not the fence.
The edge is the risky part, even when the middle of a bank is inside the percent. Dealer writing treats the edge as a lower limit than the middle, and 20% in that writing is not a second rating for the A 6v. If a pond, wall, or step leaves you short of a metre, that strip stays out of the map.
When to stop
Stop when the bank is steeper than the percent on your ASIN. On the three listings that print 45%, steeper than 45% is out. On every other ASIN here you have no percent to compare, so you do not guess one.
Stop when a drop or a pond leaves you unable to keep the 1 metre gap. A no-go zone is for a bed inside a lawn you can still frame. It does not replace a missing metre at a fall. Wet grass is an extra dealer caution: a slope that held when dry can slide when damp. If you preferred the A 4 or a cover ASIN, the slope question is unanswered, and unanswered means the bank stays out of the map.
Common questions
What does 45% mean in degrees?
On STIGA’s A 6v page, 45% is written as 24°. A 45% slope rises 45 cm over 100 cm of horizontal run. Use the pair together only for the A 6v, where both appear. The A 8v and the 5 Ah A 15v print 45% and, on these amazon listings, do not print the degree. Do not invent a degree for a row that prints neither.
Which listings actually print 45%?
Three. The A 6v (B0GMRG221S), the A 8v (B0GMR9963G), and the 5 Ah A 15v (B0GMRG616G). The A 4 prints none. The two garage-cover listings say challenging sloped terrain and print none. Both collectors print none. A shared brand is not a shared slope.
Can the A 4 do the same bank?
The listing does not say. Slope on B0F5BSFCBG is blank. Giving it the A 6v’s 45% because about £999 is close to about £949 copies a number across that blank. If the bank matters, choose a row that prints a percent, or keep the bank out of the map.
How far from a pond?
At least 1 metre, in STIGA’s manual, between the virtual perimeter and a pool, pond, or excavation. Camera and obstacle lines on some listings do not replace that gap. If you cannot draw the metre, that edge stays out and you cut it another way.
Is the camera enough at a retaining wall?
No. The manual excludes a drop by the distance you leave, not by hoping a sensor sees the void. Dealer writing says the boundary, not the camera, keeps a mower out of water, and that a wet slope can carry it past the line. Treat a wall like the pond: a metre in the map, or the wall is not in the work area.
Do the push mowers have a slope rating?
Not on these listings. The 132e and the 136e leave slope blank. A UK review of the 136e talks about a small flat patch and a height bar on uneven ground, which is holes and a spring, not a 45% bank. Do not send either collector down a slope you bought a robot to climb.
