Compare the job first, then the package
Keep both offers inside the same tool class. A handheld power cleaner and a full-size pressure washer can have very different cleaning jobs, even when both run on batteries. Use the cordless pressure-washer comparison to choose the class before comparing bundles.
| What you already have | Start with | What could change the choice |
|---|---|---|
| Enough compatible batteries, the right charger and required fittings | Tool-only offer | A kit promotion may still cost less overall |
| One battery for a tool that requires two | Both complete purchase routes | Include the cost of the missing compatible battery |
| No compatible battery system | Kit alongside a fully priced bare-tool setup | Check what the kit actually includes |
| Accessories you will not use | The package that covers your actual job | Extra pieces do not automatically add value |
A model suffix can change what is in the box
The WORX WG644 family manual, accessories chart on page 6, distinguishes these configurations:
| Documented package contents | WG644 | WG644.9 |
|---|---|---|
| WA3525 battery packs | 2 | Not included |
| WA3770 charger | 1 | Not included |
| Draw hose, lance and multi-spray nozzle | Included | Included |
Page 13 specifies two installed batteries for operation, so include two compatible packs in your tool-only setup. Use this manual-based example to make your parts list, then confirm the exact seller's current price and bundle contents before ordering.
See what the upfront total includes
Count an existing battery as covered if it is compatible and available when you need it. Include a spare only if you plan to buy one.
Compare your two complete totals
Enter both offer prices and select any missing essentials.
Upfront costs in US dollars; future upkeep is excluded. Enter 0 for confirmed zero tax or delivery. Unknown costs must be resolved before comparing.
Choose “No purchase needed” for included items or suitable equipment you already own. If a battery-and-charger bundle covers both items, put its price under batteries and mark the charger covered. For two batteries, enter their combined cost.
Check compatibility before treating a battery as reusable
Read the model numbers on your battery and charger and compare them with the exact cleaner's instructions. Voltage alone is not a compatibility check. The WORX manual's battery guidance requires designated packs and the specified charger; its accessories footnote lists the supported battery models for this family. Apply the relevant manufacturer's instructions to each offer.
Finish with a ready-to-use setup
For work away from a tap, follow the bucket-compatibility and setup guide. A box containing a hose is not enough to establish that your planned water source, filter and connections are suitable.
Once both packages cover the job, compare their complete totals and decide whether the extra contents serve you. Then use the model details and retailer links in the shortlist to check the exact offer. Recalculate if its model suffix, included parts or checkout total changes.
