DeWalt DCV501HB: problems, parts and running costs
Checked: 2026-10-17
Summary
The DCV501HB is a bare-tool 20V MAX cordless hand vacuum for jobsite and garage dry cleanup, with 46 CFM airflow, 65 air watts on a 5.0Ah battery and 2.2 lb of weight. The recurring issues are suction loss from a full tank or clogged filter, debris blowing back out of the nozzle, and the unit being bulky and overkill for everyday household use. Running costs are limited to a replacement HEPA filter every 6-9 months and battery wear; no pricing was published, so a yearly figure cannot be computed.
Common problems and fixes
- Weak or no suction — the manual’s troubleshooting list gives four causes: a full tank, a clogged filter, a low battery and a clogged nozzle. Empty the dust bowl, wash and dry the filter, charge the battery and clear the nozzle. [2]
- Dust or debris blows back out of the nozzle — the manual attributes this to a clogged guard; clear the guard. [2]
- Vacuum will not run — the manual lists a battery or switch fault; check the battery first. [2]
- Bulky for household use — Wirecutter calls DEWALT’s cordless handheld bulky and overkill for most day-to-day tasks, so it suits a garage or workshop rather than casual home use. [3]
- Dry-only — it cannot handle liquids; DEWALT sells separate wet/dry models (DCV517B, DCV580H, DCV581H) for that. [1][2]
Parts and consumables
- Belt hook — removable and reversible for left- or right-handed carry; user-replaceable with the provided screw. [2]
- Accessory kit — extension tube, flexible hose, crevice nozzle, round brush, gulper brush, floor nozzle and accessory bag, all included. [1]
Yearly running cost
Not enough data. [2]
When it is a good buy
It is the right buy when you already own DEWALT 20V MAX batteries (shared across 300+ tools) and need a jobsite-grade dry vacuum; for household-only use or a buyer outside the 20V MAX ecosystem, the total cost of vacuum, battery and charger likely exceeds household handhelds such as Black+Decker, Shark or Ryobi. Bob Vila’s tested lineup does not include the DCV501HB, and Popular Mechanics points garage and workshop buyers to the larger DCV517B wet/dry model instead. [1][3][4][5]
