How do I know what shop vac model I have?
If you have a Craftsman wet/dry vacuum, the fastest way to identify the exact shop vac model is to find the model number on the vacuum’s rating label. For this parts listing, the model is Craftsman 113177410, and matching parts always starts with confirming that number.
Where to find the model number on a wet/dry vacuum
Check these common spots on Craftsman wet/dry vacuums:
- The motor head (power head) near the switch or handle
- The back or side of the tank (canister)
- The base or caster frame
- Near the cord wrap or accessory storage area
If the label is dirty, wipe it with a damp cloth and let it dry before reading it.
If the label is missing or unreadable
You can still narrow it down using physical details, then confirm by comparing diagrams and parts lists on Sears PartsDirect.
- Tank capacity (gallons) and tank shape
- Hose diameter and hose-end style (friction fit vs locking)
- Latch style that holds the motor head to the tank
- Filter style (cartridge, foam sleeve, bag) and how it mounts
- Power switch type (toggle, rocker) and location
Quick ID checklist
| What to check | What to write down | Why it helps |
|---|---|---|
| Rating label | Model number (example: 113177410) | Most accurate match for parts |
| Motor head | Shape, latch points, switch style | Identifies the power head design |
| Tank | Capacity and port location | Narrows down the canister family |
| Hose | Diameter and connector type | Prevents ordering the wrong hose/accessories |
Why it matters
Wet/dry vacuum parts like filters, hoses, latches, and motor components are model-specific. Using the exact model number (such as 113177410) prevents fit issues and helps you get the right replacement the first time.

Where to find model number on CRAFTSMAN Wet Dry Vac?
On a Craftsman wet/dry vacuum like model 113177410, the model number is typically printed on the product rating label, most often on the lid (top) or on the tank near the motor head. Look for a sticker or plate that includes “MOD” or “Model” followed by the number.
Common places to check
- On the lid/motor head: a gray or silver sticker on the top or side of the motor housing
- On the tank/canister: near the rear, lower side, or close to the wheel area
- Near the power cord wrap or handle area
- On the underside of the lid (less common, but worth checking)
- On older units, on a metal plate riveted to the tank
What the label usually looks like
Most Craftsman wet/dry vac labels include several identifiers. Use the model number for parts lookup.
| Label item | What it means | What to use for parts |
|---|---|---|
| Model (MOD) | The exact vacuum model | Use this |
| Serial | Production identifier | Not usually needed |
| Electrical rating | Volts/amps/Hz | For troubleshooting only |
Tips to make the number easier to read
- Wipe dust off with a damp cloth and let it dry.
- Use a flashlight at an angle to highlight faded print.
- Take a close-up photo and zoom in.
Why it matters
The model number narrows your Craftsman wet/dry vacuum to the correct diagrams and compatible parts (filters, hoses, casters, switches, and motor components). For this page, the key identifier is 113177410.

What is a shop vac water lift?
Shop vac water lift (also called sealed suction) is a measure of how much suction a wet/dry vacuum motor can create, expressed as the height of a water column it can lift in a tube (inches of water lift). Higher water lift generally means stronger pickup for heavy debris and liquids on your Craftsman 113177410 wet/dry vacuum.
What “water lift” actually tells you
Water lift measures suction pressure, not airflow. It is typically measured under a sealed condition (no airflow), which is why you may also see it described as maximum sealed suction.
- Higher water lift: better at pulling up water, sludge, and heavier material
- Higher airflow (CFM): better at moving lots of light debris quickly
- Both matter: real cleaning performance depends on the balance of suction and airflow
- Sealed test: water lift is highest when the hose is blocked (zero airflow)
- In use: water lift drops as airflow increases through the hose, filter, and attachments
Water lift vs. airflow: quick comparison
| Spec | What it measures | Best for | What can reduce it |
|---|---|---|---|
| Water lift (inches) | Suction pressure | Liquids, dense debris, pulling through long hoses | Clogs, leaks, worn seals, restricted filter |
| Airflow (CFM) | Volume of air moved | Sawdust, dry debris pickup speed | Dirty filter, narrow hose, restrictions |
Why water lift changes on a wet/dry vacuum
If your Craftsman 113177410 feels weak, the issue is usually restriction or leakage rather than the motor “losing” water lift instantly.
- Check for a clog in the hose, wand, or inlet
- Make sure the filter is clean and correctly installed (or removed if your setup requires it for wet pickup)
- Inspect the lid and tank seal for gaps, cracks, or misalignment
- Confirm the hose connections are fully seated
- Look for splits or pinholes in the hose that leak suction
Why it matters
Water lift is the best single number for understanding how strongly a shop vac can pull against resistance (wet pickup, long hoses, narrow nozzles). Pair it with airflow and good sealing to get the performance you expect.

Is 200W suction power good?
Yes; 200W suction power is generally good for everyday pickup, but it is not a reliable way to judge a Craftsman 113177410 wet/dry vacuum’s real cleaning strength. For wet/dry vacs, airflow (CFM), sealed suction (water lift), hose diameter, and filter condition usually matter more than a single watt number.
What “200W suction” usually means
Manufacturers often use “watts” differently (input watts vs. suction watts), so two vacuums labeled 200W can perform very differently.
Key performance specs to compare instead:
- Airflow (CFM): Higher CFM moves more debris through the hose.
- Sealed suction (water lift): Higher water lift helps with heavier debris and longer hoses.
- Hose diameter and length: Wider, shorter hoses reduce clogging and improve pickup.
- Filter type and condition: A clogged filter can cut suction dramatically.
- Tank seal and latches: Air leaks reduce suction even if the motor is strong.
Quick checks if suction feels weak
Before assuming the motor is underpowered, we recommend these practical checks:
- Empty the tank and confirm the lid is seated evenly.
- Inspect the hose for clogs (especially at the cuffs and bends).
- Clean or replace the filter; confirm it is installed correctly.
- Check for cracks in the hose, tank, or lid gasket area.
- Test suction at the inlet (no hose) vs. at the nozzle to isolate restrictions.
Typical “good” suction guidance (simple comparison)
| Cleaning need | What matters most | What to look for |
|---|---|---|
| Fine dust (drywall, sawdust) | Filtration and airflow | Clean filter, strong CFM, good seals |
| Wet pickup | Seals and float shutoff behavior | Proper lid seal, clear airflow path |
| Heavy debris (shop cleanup) | Hose size and airflow | Larger hose diameter, fewer restrictions |
| Deep carpet (if used indoors) | Nozzle design and agitation | Proper floor tool, steady airflow |
Why it matters
If you shop or troubleshoot using only “200W,” you can miss the real cause of poor performance (clog, leak, or filter restriction). Using airflow, water lift, and basic maintenance checks gives a more accurate picture of how your Craftsman wet/dry vacuum will perform.
