Leaf blowers
Which 3000 W blower actually moves more air?
These two publish their air volume in different units, which makes the headline figures look incomparable. They are not: 15 cubic metres a minute is 900 cubic metres an hour. Once both are in the same unit the comparison is straightforward, and it goes the opposite way from the bag volumes.
| Compared on | Trivac WG505E | BEBLV301-QS |
|---|---|---|
| Input power | 3000 W | 3000 W |
| Air speed | Up to 335 km/h | 404 km/h |
| Air volume | 600 m³/h | 15 m³/min — that is 900 m³/h |
| Bag volume | 45 L with a shoulder strap | 72 L backpack with a quick release |
| Mulch ratio | 16:1 with a metal impeller | 16:1 |
| Mode change | One button, 3-in-1 | Blow, vacuum and shred, adjustable power |
| Weight | Not published — described as compact and one-handed | Not published |
A tick means one listing published something the other did not, or published a better figure. It does not mean the product is better, and the column is not a score out of anything: a maker who says less loses lines here without losing a comparison. The two verdicts below are where the page is settled.
WORX publishes a metal impeller behind the same 16:1 mulch ratio, and that is the part that decides whether the ratio survives. An impeller shreds leaves by hitting them, along with the twigs and small stones that come up with them, and a plastic one wears its edges round within a season. It also changes mode with one button rather than a tool.
Converted into the same unit, BLACK+DECKER moves half again as much air — 900 cubic metres an hour against 600 — at a higher speed, into a bag three fifths larger, carried on the back rather than the shoulder. For clearing a large area of dry leaves those four figures are the whole job, and it wins all four.
Speed moves a stuck leaf; volume moves a pile. A high-speed narrow jet lifts wet leaves off gravel, and a high-volume flow pushes a drift of dry ones across a lawn. Both listings publish both figures, which is more than most of this shelf manages.
That sixteen bags of leaves come out as one bag of shredded material. It is the reason a vacuum function is worth having at all, because it turns a leaf problem into a compost input. Both machines publish the same ratio, and only one publishes what the impeller is made of.
For a full bag, considerably. Forty-five litres of shredded leaves on one shoulder pulls you sideways for as long as it takes to fill it, and the backpack carries seventy-two without doing so. Two straps and a quick release is the arrangement for a long session; a shoulder strap is lighter to put on and off for a five-minute job.
3000 W, 335 km/h, 600 m³/h, 16:1 metal impeller, 45 L
Blow, vacuum and mulch at 335 km/h and 600 m³/h, with a metal impeller, a 16:1 ratio and a one-button mode change.
Best for: A medium garden with a mix of paving and lawn, where the machine switches modes constantly
3000 W, 404 km/h, 15 m³/min, 72 L backpack, 16:1
The fastest air on this shelf at 404 km/h, with a 72-litre backpack bag, a 16:1 shredding ratio and a rake attachment.
Best for: A large garden with trees, where an autumn session means filling a bag several times
The live figure beside a product went and asked the shop for it the moment this page opened; any amount written into the text has not moved since the sentence was drafted, and it is the first of the two that counts.
