Cordless string trimmers

(75)

Cordless string trimmers are the ideal choice for anyone who wants a neatly maintained garden without unnecessary effort and cables. A cordless string trimmer is perfect for trimming grass around fences, trees, flower beds, or curbs – basically anywhere a standard lawn mower cannot reach. If you are looking for a practical solution for garden detailing, cordless string trimmers will save you both time and energy.

In our range you will find models for small front gardens as well as powerful machines for demanding users. A modern cordless string trimmer can handle denser vegetation and will quickly become your favorite partner for garden maintenance.

What is a cordless string trimmer used for and why should you buy one?

A cordless string trimmer works on the principle of a rapidly rotating line that cuts through grass and light vegetation. Compared to larger mowers, it is lightweight, compact, and easy to handle.

Most common uses:

trimming lawn edges
working around trees, shrubs, and walls
maintaining small and irregular areas
as a supplement to a standard lawn mower

What to consider before buying a cordless string trimmer?

Before choosing a model, consider several key questions. The right choice depends mainly on the character of your garden.

How large is the area you will be trimming? This determines battery capacity and cutting width.
What exactly will you be cutting? Light lawn edges can be handled by a basic cordless trimmer, while tougher weeds require a more powerful model with higher voltage.
Do you already own cordless garden tools? Many manufacturers offer shared battery systems, allowing one battery to power multiple tools such as trimmers, hedge cutters, or cordless lawn mowers.
Who will be using the tool? If it will be used by a senior or someone less physically strong, weight and ergonomic design are crucial.

Electric vs. cordless string trimmers

Are you deciding whether to choose a battery-powered trimmer or an electric string trimmer?

The main advantages of cordless models include:

Full mobility – reach every corner of your garden without needing a power outlet.
Low noise level – you can work even early in the morning without disturbing neighbors.
Eco-friendly operation – no emissions and no fuel or oil maintenance.
Instant start – just press a button and you are ready to work.

SANITINO tip: If you have a small garden with easy access to electricity, an electric string trimmer may be sufficient. However, for maximum comfort and freedom without cables, a cordless model is the clear winner.

How to choose the right cordless string trimmer?

When comparing models, focus on key technical parameters that affect performance and comfort.

What battery should you choose?

The battery is the heart of every cordless tool.

Pay attention to two main values:

Voltage (V) – determines motor power. 18V is sufficient for light trimming, while 36V systems are better for dense vegetation and tougher terrain.
Capacity (Ah) – determines runtime. A 2.0 Ah battery lasts around 15–25 minutes, while 4.0–5.0 Ah batteries provide significantly longer operation.

Cutting width

Typically ranges from 23 to 35 cm. A wider cutting path means faster work. Smaller models are ideal for detail work, while larger ones cover bigger areas more efficiently.

Cutting system – line or blades?

Most models use nylon line. Some cordless trimmers offer automatic or semi-automatic line feed systems. Advanced models may allow replacement of the trimmer head with plastic blades for tougher vegetation.

Weight and ergonomics

A lightweight design with adjustable handle and telescopic shaft significantly improves comfort during use.

Kit with battery vs. tool-only version

If you are new to cordless tools, a complete set with battery and charger is the best choice. If you already own compatible batteries, you can purchase the tool-only version and save money.

Battery runtime

Runtime depends on battery capacity and working conditions:

approx. 20–30 minutes (2 Ah)
approx. 40–60 minutes (4 Ah)

Heavier vegetation reduces runtime.

Which battery is best?

It is best to stick with one brand so you can share batteries across multiple tools, making your equipment more flexible and cost-efficient.

Why you should not trim wet grass

A common mistake is trimming wet grass. Why is it not recommended?

grass sticks to the line and housing
cutting becomes uneven
motor load increases
risk of damage to the tool

Always wait until the grass is dry for best results.

Which cordless string trimmer is the best?

There is no universal “best” model – it depends on your garden size and needs. Smaller gardens require lightweight tools, while larger areas need more powerful models with higher voltage and capacity.

Recommendation: For effortless lawn maintenance, consider also our robotic lawn mowers, which handle the main mowing while you finish edges with a trimmer.
