The WG588 is the machine that explains why impeller design matters. It uses triple-layer metal impellers rather than a plastic blade, and the listing states a 20:1 mulch ratio, which means twenty bags of leaves shrink toward one bag of mulch. Metal blades hold an edge longer and tolerate the occasional twig better than molded plastic, which is the usual failure point on cheaper vacuums.
Its 600 CFM and 100 MPH claims show a design aimed at volume over jet speed, which is the right balance for pulling leaves into the tube. Compared with the WG583 at 340 CFM and 210 MPH, it trades blowing speed for suction, and it also switches from blow to vacuum without tools.
Ownership centers on the 40V WORX battery family, so packs can be shared with other tools. Check whether the listing includes a pack and charger, since that changes the real cost. Empty the bag at half full, store the battery indoors and clear the impeller with the pack removed. It is the right choice for a homeowner who wants the vacuum to last. Expect the vacuum tube to feel long and slightly nose-heavy once the bag fills, so adjust the shoulder strap before you start. Keep the batteries on the charger overnight before a big weekend session, and swap them when the output drops rather than running them flat.
What works
- Triple-layer metal impellers resist wear
- Stated 20:1 mulch ratio cuts bag count
- Toolless switch between blow and vacuum
- Brushless 40V platform with shared batteries
Watch out for
- Low 100 MPH speed is weaker for pavement debris
- Check whether battery and charger are included
