The VonHaus cordless scarifier is the only machine on this list that arrives with its batteries in the box: the listing names two 20V 4Ah packs and a dual charger, which is why it costs £239.99 where the £164.99 cordless higher up the ranking is a bare tool. It takes the number 10 slot here.

The '40V' in the title is those two 20V packs added together rather than a voltage any part of the machine runs at, and the listing gives its runtime as 'up to 25 minutes (no-load)' — a figure taken with nothing resisting the drum. Everything on this page comes from the product's Amazon listing and not from a test by us.

## Questions people ask

**Does the VonHaus scarifier come with batteries?**

Yes. The specification line reads '2 Lithium Ion batteries required. (included)', and the bullets describe two 20V 4Ah batteries plus a dual battery charger that refills them in two hours.

**Why is it called 40V when the batteries are 20V?**

Because two 20V packs are quoted together as 40V. The listing never states that any part of the machine runs at 40 volts.

**How long does a charge last?**

The listing quotes 'up to 25 minutes (no-load)'. No-load means the drum is turning with nothing resisting it, so a lawn full of moss will not match that figure.

**How deep does it scarify?**

There are five depth settings between -12mm and 6mm. VonHaus recommends starting at the highest position and lowering it to suit the lawn.

**The title says scarifier, aerator and rake — how many drums are there?**

The bullets describe it as '2-IN-1' with a raking drum for moss and a scarifying drum for root removal, swapped over by hand. Two drums are listed, not three.

**Why do the star bars not match the review count?**

The listing shows 55 ratings, while the bar breakdown of 6 one-star, 7 three-star, 14 four-star and 73 five-star totals 100. Either the bars are percentages or one of the two figures is wrong.
