Price and rating as shown on Amazon when we collected them. Both change.
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.
