We recommend the Mowrator S1 4WD 85% for a large property with steep ground that is unsafe or exhausting to mow on foot. It is rated for 85% (40°) slopes, runs up to 2.25 hours on its 18Ah battery and lists up to 4,500 m² per charge, with a 53 cm deck and wide wheels for traction. At €5,199 it sits between the 75% and 119% models; choose it when your slopes are steeper than 75% but not extreme.

The quick answer
The Mowrator S1 4WD 85% is a remote-controlled mower rated for 85% (40°) slopes, with all-wheel drive on wide wheels, a 53 cm deck, an 18Ah battery for up to 2.25 hours and a leaf-shredding vacuum mode. You steer it from a distance, so it is not an autonomous robot. Choose it for large, steep properties; the 75% model costs less for gentler slopes and the 119% model is for the steepest banks.
Why we like it
- Rated for 85% (40°) slopes with all-wheel drive on wide wheels for traction
- An 18Ah LiFePO4 battery: up to 2.25 hours and about 4,500 m² per charge, manufacturer figures
- A 53 cm deck with five cutting heights from 3.8 to 10.9 cm and about 2,000 m² per hour
- Mulch, rear bag and side discharge, plus a leaf-shredding vacuum mode with a 70 L bag
- Four ultrasonic sensors, bumper protection, remote emergency stop and tilt protection
Before you buy
- It is remote-controlled, so you operate it for the whole job.
- A slope rating is a manufacturer maximum; wet grass and loose ground reduce grip.
- At 66 kg it is a heavy machine to transport and store.
- The product page showed both In stock and Sold out blocks, so confirm availability before ordering.
Why we like the 85% S1 for large, steep properties
A big sloping property is where a push mower and most robot mowers run out of road. The S1 4WD 85% is built for it: all-wheel drive on wide wheels, an 85% (40°) slope rating and a 53 cm deck that Mowrator lists at about 2,000 m² per hour. You stand on level ground with the remote and the mower does the climbing. That removes the hard and risky part of the job, and its 4,500 m² per charge is enough for most gardens in a single session.
How it fits between the 75% and 119% models
The S1 range shares its deck, remote and four cutting modes. The 75% 4WD model suits moderately steep ground, the 119% model is set up for extreme gradients with grip tread tires, and the 85% version adds wide wheels and the larger 18Ah battery between them. If your steepest section is closer to 75%, the cheaper 12Ah model may be enough; if you mow near-vertical banks, look at the 119%.
Everyday mowing and leaf cleanup
Mowrator lists five cutting heights from 3.8 to 10.9 cm and three grass-handling modes: mulch, rear bagging and side discharge. Switch to the leaf-shredding vacuum in autumn and the 70 L bag collects shredded leaves. The 18Ah battery gives about 2.25 hours between charges and recharges in 90 minutes. Four ultrasonic sensors, bumper protection, tilt protection and a remote emergency stop add safeguards, though you stay responsible for watching the mower.
What to know before you buy
You steer the S1 for the entire job; there is no scheduling or unattended mowing. At 66 kg it needs a ramp or two people to load, and slope ratings are maximums on firm ground, not guarantees on wet grass. The product page showed both In stock and Sold out blocks when we checked, so confirm availability and delivery time with the store before you commit.
Our buying advice
Buy the 85% S1 if your property is large, your slopes are steeper than 75% and you want the 18Ah battery. Mowrator lists it at €5,199, and its code SEBASTIANBASSOL reports €200 off, which would bring it to €4,999 if it applies to this model; confirm the total at checkout because eligibility has not been verified. Choose the 119% model only for the steepest banks.
