## At a glance

- Cordless wet/dry cleanup in a 2.5-gallon format, with the listing recommending it for garage use and all floors.
- Manufacturer claims up to 63 CFM and 82 inches of water lift. These are listing specifications, not independently verified measurements.
- Push-button manual filter cleaning is intended to clear debris buildup from the filter.
- A compatible wireless remote is optional and sold separately.

## Pros

- HEPA filtration is specified, with a manufacturer claim of filtering 99.97% of particles .03 microns or larger.
- Manual filter cleaning offers a built-in way to clear filter debris without presenting it as automatic cleaning.
- The compact listed capacity and handheld form may suit portable spot cleanup and garage tasks.

## Cons

- The tool-only configuration means batteries and a charger are sold separately, adding required purchases for buyers without compatible power equipment.

## Before you buy

- The description also mentions a flexible hose, dust bag, shoulder strap, nozzles and attachments, while the explicit included-components field lists only an anti-static hose and HEPA filter. Confirm the selected listing's package contents. The title says tool only, and the description says batteries and chargers are sold separately.

## In the box

- Anti-static hose (Included)
- HEPA filter (Included)

## A good fit for

- FLEX battery-system owners who want a cordless wet/dry vacuum for garage or portable cleanup and can supply a compatible battery and charger.
- Buyers who value listed HEPA filtration and the ability to manually clear filter buildup.

## Less suited to

- Buyers who need a complete ready-to-run kit with battery and charger included.
- Those who need a larger-capacity vacuum than the listed 2.5 gallons.

## Customer feedback

The supplied evidence contains aggregate ratings but no written customer-feedback summary. The ratings lean strongly toward the top two star categories, but the small sample does not establish particular strengths, concerns or performance reasons. Consider them limited context alongside the listed 2.5-gallon capacity and tool-only configuration.
