Bosch Indego S+ 500 or Dreame A2 1200: The Short Answer

If you don't want to read the whole comparison: the Bosch Indego S+ 500 is the default pick and the one we recommend to most people, and the Dreame A2 1200 beats it in one specific scenario — when your priority is Everyday Use. The real difference between the two isn't in the spec sheet, it's in how they perform for the way you'll actually use them. We break it down point by point below.

The rain sensor isn't always worth turning on

Cutting wet grass muddies the housing, mats the clippings and leaves wheel marks. But if the robot takes shelter every time it rains in high-rainfall areas, it falls behind schedule and patches of grass grow too tall to trim in a single pass. In rainy climates, the usual strategy is disable the sensor and clean more often.

Noise level is the competitive edge almost no one mentions

A gas-powered mower runs around 95 dB; a robot mower sits between 55 and 65 dB, comparable to a conversation. That lets you mow at times of day that would be impossible with a conventional machine and eliminates neighbor complaints. In communities and terraced houses, this is often the deciding factor, ahead of the time saved.

Pivoting blade vs. disc with fixed blade

Most robots use small pivoting blades scalpel-type: they cut through speed, are dirt cheap to replace, and if they hit a stone, they fold back instead of breaking the motor. The fixed blade propeller-type blades cut taller, coarser grass, but they put more strain on the machine on impact. For regular lawn maintenance, pivoting blades are the sensible choice; replace them every 6-10 weeks.

Lithium batteries last longer when stored partially charged

At the end of the season, the battery shouldn't be stored at 100% or empty: the right level is around 50-60%, in a dry, frost-free spot, and topping up the charge halfway through winter if the robot will sit idle for months. Storing a lithium battery fully discharged all winter is the most effective way to kill it.

The stated maximum slope is the spec that gets broken the most

A robot advertised for 35% slope achieves that on dry, firm grass. With wet grass, the wheels slip and the machine ends up stuck sideways or sliding. If your garden has slopes, look at the wheel type (deep lugs or four-wheel drive), not just the percentage. And on real-world slopes, it's wise to leave a 5-10 point margin.

The charging base has its own set of requirements

The station needs flat ground, in the shade if possible, with several meters of straight approach path and no pooling water when it rains. If it's placed on a slope or the approach curves, the robot will miss the docking connection and run out of battery halfway through the garden. And the transformer needs to be outdoors under protection or inside a ventilated cabinet.

Verdict: which one to choose

The Bosch Indego S+ 500 for most people; the Dreame A2 1200 if your main use is Everyday Use. Neither is a bad buy — they're just different profiles: the mistake would be choosing based on one day's price instead of how you'll actually use it over the coming years. Check the current price of both before making your final decision.

Frequently Asked Questions

What height should I mow at?

Never remove more than a third of the blade height at once. In summer, raise the cutting height to shade the soil and retain moisture; in spring you can lower it. A robot fixed at 2 cm in the middle of August will scorch the lawn.

Is it safe around children or pets?

It has lift and tilt sensors that stop the blade, but the blade spins very fast and there shouldn't be children or loose pets around while it's working. And schedule it during the day: nighttime mowing causes a lot of hedgehog and amphibian deaths.

How many square meters does a robot actually cover?

Considerably less than what the box says if your garden is irregular. The stated figure assumes long working days and a clear surface. With trees, flower beds and narrow passages, allow a 30% margin over your measured area.

What should I do with the robot in winter?

Deep clean, new or inspected blades, and the battery stored at 50-60% in a dry, frost-free spot. Top up the charge halfway through winter. Storing it discharged for months is the fastest way to ruin the battery.

How often should the blades be replaced?

Pivoting blades, every 6-10 weeks of use or sooner if you notice the grass looking frayed instead of cut. They're very cheap, and replacing them is the maintenance task that makes the biggest visible difference to your lawn. Replace them all at once so the disc stays balanced.

Should I Go With the Bosch Indego S+ 500 or the Dreame A2 1200?

The Bosch Indego S+ 500 is the most balanced option and the one we recommend by default. The Dreame A2 1200 makes sense if your priority is Everyday Use. As a budget reference, the useful range starts around €200 and the best balance tends to sit around €320.
