A third battery changes the job
With two packs you cut while one charges. With three, a half-acre of trimming, edging and mowing happens in one go — then the washer gets a fresh pack for the clean-up.

Will the trimmer-mower really mow my lawn?
Will the trimmer-mower really mow my lawn?
A small one, yes: townhouse lawns, side strips, slopes and the places a 21-inch mower can't turn. It cuts a 13.7-inch swath at 45, 60 or 75 mm on the included wheels. It is not a replacement for a full-size mower on a quarter acre or more.
How long do the batteries last?
How long do the batteries last?
Trimmer-mower: two 21V packs in the box, swap when one runs down; run time depends on grass height and the head in use. Washer: one 4.0Ah pack, about 20–30 minutes of spraying per charge, 3–4 hours to recharge. The spare 21V pack fits both.
Does the washer need an outdoor tap?
Does the washer need an outdoor tap?
No. The 200-inch intake hose with its filter draws from a bucket, pool, rain barrel or any container. Fill a bucket from the kitchen sink and wash the car in the street.
What pressure is the washer?
What pressure is the washer?
Pressure is adjustable through the 6-in-1 nozzle, from a soft shower for plants to a tight jet for wheel wells and patio grime. It is a cordless, bucket-fed washer for cars, patios and furniture — not a 2,000 PSI driveway stripper.
Is the saw blade safe for branches?
Is the saw blade safe for branches?
It is for light brush and woody weeds, not branches. For live branches up to 5/8 inch we sell the Fiskars bypass pruner alongside it; wear eye protection and closed shoes with every head.
