Is the Worx WG545.1 strong enough to clear leaves from a lawn?

Only for light work. At 80 CFM it moves dry leaves off a deck or driveway, but wet or heavy piles on a large lawn will take a long time. For fall cleanup on a full yard, a corded or higher-CFM blower is a better fit.

How long does the battery last and how long to charge?

Worx rates the included 2.0 Ah battery at about 14 minutes of run time. A full recharge takes about five hours, so a spare 20V Power Share battery helps on longer jobs.

What comes in the box?

The kit includes the blower, the 20V 2.0 Ah battery, a charger, a wide nozzle, eight attachments and a bonus deflator attachment for air mattresses and pool toys.

Can I use my other Worx 20V batteries in it?

Yes. It runs on any Worx 20V Power Share battery, the same line used on Worx chainsaws and cordless mowers. A larger battery adds run time but also weight.

Does it vacuum or mulch leaves?

No. The WG545.1 only blows and sweeps. It has no vacuum or mulching capability, so bagging leaves needs a separate tool.

Is $89.99 a good price?

It is a low price for the battery-included kit and sits at the bottom of its recent range. Six stores list it new, so compare before buying if you want a spare battery bundled.
