Bosch VISIMOW18V-100 Robot Lawn Mower (Green, Up To 100m², Without Battery)

Does the Bosch VISIMOW18V-100 come with a battery and charger?

No. This listing is for the mower unit only sold without battery and charger. It is compatible with the Bosch POWER FOR ALL 18V battery platform. If you already own an 18V POWER FOR ALL battery from Bosch or another compatible brand you can use it directly. If not you will need to purchase a battery and charger separately before you can use the mower.

What size lawn is this mower suitable for?

The VISIMOW18V-100 is designed for lawns up to 100m². It can also handle multiple separate lawn zones within that total area. This makes it suitable for small to medium gardens where a path or patio divides the lawn into sections. For larger gardens you would need to look at a higher-capacity model.

Do I need to lay boundary wires around my garden?

No. This is one of the key differences with this mower. The Smartvision system uses camera-based navigation to map and work within your lawn without any physical boundary wires or ground-level infrastructure. This removes the need for installation work entirely and means you can move the mower between different lawns without any reconfiguration.

How long does the battery last per mowing session?

Based on a verified UK buyer review the mower runs for approximately 4 hours on a 4Ah battery before the battery needs changing. Runtime will vary depending on battery capacity, grass thickness and terrain. Bosch does not publish an official runtime figure in the product listing so real-world usage data from buyers is the best available reference point at this stage.

Which batteries are compatible with this mower?

The mower uses the Bosch POWER FOR ALL 18V battery system. This platform spans 10+ brands and 150+ products. Compatible batteries include those from Bosch, Gardena and other POWER FOR ALL alliance members. Always check the specific battery voltage and connector type before purchasing to confirm compatibility with this model.

Is the battery easy to remove from the mower?

One verified buyer reported that the battery release latch can be stiff and tricky to operate, particularly with a newer battery. The same buyer noted it became easier with a battery that had some wear on it. A separate buyer received a unit with a faulty latch mechanism that prevented battery removal entirely. This appears to be an early production issue worth being aware of when inspecting a new unit.

What is the cutting height range and how is it adjusted?

The cutting height adjusts between 20mm and 60mm. This gives a reasonable range from a short formal lawn finish up to a longer grass setting suitable for tougher conditions or summer dry periods. The product listing does not specify whether adjustment is manual or tool-free so it is worth checking the user manual or contacting Bosch directly for clarification on the adjustment mechanism.

Will the mower leave any areas of the lawn uncut?

The mower has a 16cm cutting width and one buyer noted it leaves approximately 5 inches (around 12.7cm) of grass uncut around lawn borders. This is fairly typical of robot mowers due to the physical clearance needed between the cutting blade and the mower body. You would likely need a strimmer or edging tool to finish the perimeter after each mowing session.
