Craftsman 113177905 wet/dry vacuum Parts

On the Craftsman wet/dry vacuum model 113.177905, the model and serial number label is located on the handle. We recommend writing both numbers down and keeping them with your paperwork for faster parts lookup and service reference (see the 113177905 owner's manual).

Where to look on the vacuum

Check these common label locations first (starting with the most likely for this model):

• Handle area: look along the handle tube or near the top grip
• Under the lid: lift the powerhead (lid) and check the underside edges
• Rear of the powerhead: near the cord wrap or switch area
• Drum (tank) exterior: upper rim area where the lid seats

What you should record (and why)

For model 113177905, we suggest recording both identifiers exactly as shown.

Item	What it’s used for	Example format
Model number	Matching diagrams and repair parts lists	113.177905
Serial number	Identifying production run for service and support	Letters and numbers

Tips if the label is hard to read

If the sticker is worn, you can usually still recover the information.

• Wipe the label gently with a damp cloth; avoid solvents that can erase printing
• Use a flashlight at an angle to make faint text stand out
• Take a close-up photo and zoom in
• If only part of the model is visible, match the full model format in the 113177905 owner's manual

Why it matters

The model number is the fastest way to get the right Craftsman wet/dry vacuum parts (filters, hoses, casters, lid gasket) and to ensure any repair instructions match your exact configuration.

For the Craftsman wet/dry vacuum model 113177905, you can leave the filter installed for small water pickups, but we recommend removing the filter for large amounts of water to prevent the filter from saturating and causing exhaust misting. Use the float shutoff to avoid overfilling (see the 113177905 owner’s manual).

What to do for wet pickup (quick steps)

• Turn the switch to OFF (0) and unplug before changing the filter.
• Small spills: filter can stay in place.
• Large water pickup: remove the filter first.
• Watch for loss of suction and a higher-pitched motor sound; that indicates the float has risen.
• Turn the vac OFF, unplug, and empty the drum when the float shuts off airflow.
• After wet pickup, dry the filter completely before storing.

Filter guidance: small vs. large water pickup

Pickup situation	Filter installed?	What you may notice	Best practice
Small amount of water	Yes	Normal operation	Empty drum as needed; dry filter afterward
Large amount of water	No (recommended)	Less chance of misting	Remove filter; rely on float shutoff
Switching back to dry debris	Yes (dry filter only)	Wet filter clogs fast	Dry filter first; run vac about 10 minutes without the hose to speed drying

Why it matters

A saturated filter restricts airflow, which reduces suction and can create misting at the exhaust. Drying the filter after liquid pickup also helps prevent mildew and extends filter life.

Safety notes we follow

• Never vacuum burning or smoking materials (cigarettes, matches, hot ashes).
• Don’t use the vac without a filter installed except when vacuuming liquids as described for wet pickup.

To remove the filter on your Craftsman wet/dry vacuum model 113177905, turn the vac off and unplug it, then unscrew the filter nut on the filter cage, lift off the filter plate, and lift the filter straight off. Follow the steps in the 113177905 owner's manual.

Step-by-step: filter removal (for cleaning or replacement)

• Unplug the wet/dry vac and remove the power head (motor assembly) from the drum.
• Locate the filter cage in the center of the power head.
• Unscrew the filter nut from the filter cage.
• Remove the filter plate.
• Lift the filter off the cage.
• Reinstall in reverse order; keep the filter properly seated for dry pickup.

Important safety and performance notes

• Do not remove the filter cage; it helps protect fingers from the blower wheel.
• For dry material pickup, always reinstall the filter to help prevent dust leaks and protect the motor.
• If you picked up liquids, dry the filter before storing to help prevent mildew and damage.

Dry vs. wet pickup: when to leave the filter on

Task	Filter installed?	Why
Dry debris and dust	Yes	Helps prevent leaks and protects the blower and motor
Small amounts of liquid	Usually yes	Filter can stay in place for light liquid pickup
Large amounts of liquid	Remove recommended	Helps prevent saturation and exhaust misting

Why it matters

A correctly installed, intact filter is a key part of suction and dust control. A wet or damaged filter clogs faster, reduces airflow, and can let fine dust blow back out through the exhaust.

Shop vacuums (including the Craftsman 113177905 wet/dry vacuum) usually lose suction because airflow is restricted: a clogged or wet filter, a blockage in the hose/nozzle, a full drum, or the float shutting off airflow during liquid pickup. Start with the filter and hose, then check the drum and float.

Most common causes (and what to check first)

• Filter clogged with fine dust: Remove and clean the filter; replace it if it is torn or won’t clean out well.
• Filter is wet: A wet filter clogs quickly when you switch back to dry pickup; dry it before vacuuming dust.
• Hose, wand, or nozzle blockage: Look for packed debris at bends and at the inlet.
• Drum is too full: A full drum reduces airflow and can push debris into the filter.
• Float shutoff activated (liquid pickup): When the drum reaches a set level, the float rises and airflow stops.

Quick troubleshooting steps (10 minutes)

1. Unplug the vac.
2. Remove the hose and check suction at the inlet.
3. Inspect the hose/nozzle for clogs; clear debris.
4. Check the filter condition (dry, not torn, seated correctly).
5. Empty the drum and re-test.

Dry pickup vs. liquid pickup: what changes

Situation	What typically happens	What to do
Dry debris and dust	Filter loads up and restricts airflow	Clean or replace the filter; keep it dry
Picking up large amounts of liquid	Filter can saturate; misting may appear; float can stop airflow	Remove filter for large liquid pickup; empty drum when float trips; dry filter afterward

Why it matters

Low suction is almost always an airflow problem. Fixing it quickly protects the motor from overheating and keeps fine dust from clogging the filter so badly that it becomes difficult to clean.

To empty your Craftsman wet/dry vacuum model 113177905, turn the switch to OFF (0), unplug it, remove the powerhead (motor cover), and dump the debris from the drum into a trash can. For fine dust, empty and clean more often to keep strong suction.

Step-by-step: empty the drum (tank)

• Move the switch from ON (1) to OFF (0).
• Unplug the power cord before opening the vacuum.
• Release the latches and lift off the powerhead (motor cover).
• Carefully dump debris from the drum into a trash can.
• Wipe the drum out; wash with warm water and mild soap when needed.
• Reinstall the filter in the correct position before dry pickup.

Wet vs. dry pickup: what to do with the filter

Keeping the filter setup right prevents leaks, clogging, and misting.

What you are vacuuming	Filter setup	What to do after emptying
Dry debris (sawdust, dirt)	Filter installed and dry	Clean filter more often if suction drops
Very fine dust	Filter installed	Empty drum and clean filter more frequently
Small liquid amounts	Filter can stay in place	Dry the filter afterward
Large liquid amounts	Remove filter	Dry the drum and filter to prevent mildew

Why it matters

A full drum and a dusty or wet filter restrict airflow. That reduces suction and can make fine dust clog the filter quickly. Emptying the drum regularly and keeping the filter dry helps your 113177905 perform at peak vacuum performance.

For the Craftsman wet/dry vacuum model 113177905, the parts list includes the main vac assembly plus the hose and nozzle set, filter components, and a float system used during wet pickup. For the complete model-specific parts breakdown and diagrams, use the 113177905 owner's manual.

Model 113177905 parts and accessories (typical list)

These are the common components called out for this Craftsman wet/dry vac:

• Vac assembly (motor cover and drum as the main body)
• Pos-I-Lock hose assembly and hose lock
• Extension wands
• Utility nozzle, car nozzle, and wet nozzle (squeegee style)
• Filter system parts: filter (red stripe), filter cage, filter plate, filter nut
• Float (helps prevent overfilling during liquid pickup)

What each system does

Knowing the function helps you choose the right replacement part.

Part or system	What it does	Common symptom when it needs attention
Filter system	Traps dust before air reaches the motor	Low suction, dust blowing out exhaust
Hose and wands	Carry airflow and debris to the drum	Whistling air leak, weak pickup
Float (wet pickup)	Limits airflow when liquid level gets high	Sudden loss of suction during wet pickup
Wet nozzle (squeegee)	Pulls liquid off smooth floors	Streaking, poor liquid pickup

Quick tips to identify the right part

• Match the model number exactly: 113177905
• Separate wet-pickup accessories (wet nozzle, float) from dry-pickup items (filter)
• For low suction, check for a clogged filter, a blocked hose, or a full drum
• For wet pickup, inspect the wet nozzle squeegee edge and confirm the float moves freely

Why it matters

Using the correct filter and accessories keeps suction strong and protects the motor. A wet filter clogs quickly when you switch back to dry debris, so keeping the filter dry for dry pickup prevents performance problems.
