Craftsman 113177110 2-gallon wet/dry vacuum Parts

For the Craftsman 113177110 2-gallon wet/dry vacuum, we recommend removing the filter for wet pickups. The owner’s manual notes that filter removal is recommended when vacuuming liquids, and running with a wet filter can quickly clog it and reduce suction (and make it hard to clean). See the 113177110 owner’s manual.

What to do before vacuuming water

• Turn the vac OFF and unplug it.
• Remove the power head and take off the dry filter (and any dust bag, if used).
• Confirm the float mechanism moves freely (it shuts off airflow when the drum fills).
• Reinstall the power head securely so you do not create an air leak.
• Vacuum liquids; when suction stops and motor pitch rises, empty the drum.

Wet vs. dry setup (quick comparison)

Pickup type	Filter installed?	What you will notice if set up wrong
Dry debris (dust, sawdust)	Yes	Dust can blow out the blower port; motor can ingest debris
Liquids (water)	No (recommended)	Filter can waterlog, clog fast, and suction drops

Why it matters

Using the correct setup protects airflow and helps prevent performance problems. On model 113177110, the float is designed to stop airflow at a preset liquid level; continuing to run the motor with the float raised can damage the vac.

Parts that commonly come up with wet pickup

If you need to replace a worn attachment or improve reach, check compatible accessories such as the wet/dry vacuum hose, 1-1/4-in x 6-ft 551013109.

To remove the filter on the Craftsman 113177110 2-gallon wet/dry vacuum, unplug the vac, remove the power head (top), then stretch the retainer band off its plastic posts and slide the filter bag off the filter cage. Handle the filter carefully to avoid tears.

Step-by-step: filter removal on model 113177110

• Turn the switch OFF and unplug the power cord.
• Release the side latches and lift off the power head assembly.
• Turn the lid upside down so you can access the filter area.
• Stretch the retainer band off the plastic posts.
• Pull the filter bag straight off the filter cage.
• If you were vacuuming liquids, keep the filter removed until you switch back to dry pickup.

For diagrams and the exact filter and retainer band setup, use the 113177110 owner’s manual.

Reinstalling the filter correctly (to prevent dust blow-by)

When you are ready for dry pickup again, make sure the filter is seated and sealed:

What to check	What “correct” looks like
Filter position	Filter fully covers the filter cage
Retainer band	Band sits close to the lid with no gaps
Filter condition	No holes or tears; replace if damaged

Why it matters

A loose, wet, or torn filter can clog quickly, reduce suction, and allow fine dust to bypass the filter and blow out of the blower port. Keeping the filter installed for dry pickup also helps protect the blower wheel and motor.

On the Craftsman wet/dry vacuum model 113177110, the model number is typically printed on the serial label on the right side of the vac top (power head area). Use that exact model number when ordering parts or checking the correct owner information in the 113177110 owner’s manual.

• Right side of the vac top (power head), near the handle area
• On or near the carry handle (some labels include model and serial together)
• Along the upper housing where the latches meet the dust drum
• Near the cord wrap area on the power head

Tips to read the label clearly

If the label is dusty or worn, these steps usually help:

• Unplug the vac before handling it closely
• Wipe the label gently with a damp cloth and mild soap, then dry it
• Use a flashlight at an angle to make faded printing easier to see

Shop vacuums usually lose suction because airflow is restricted or leaking. On the Craftsman model 113177110 (2-gallon wet/dry vacuum), the most common causes are a clogged filter, a clogged hose, or an air leak where the power head seals to the dust drum; see the troubleshooting section in the 113177110 owner’s manual.

Most common causes (and what to check first)

• Clogged filter: Fine dust loads the filter quickly and reduces airflow.
• Clogged hose or nozzle: Debris can lodge in the hose bends or at the port.
• Air leak at the lid/drum seal: If the power head is not latched evenly, suction drops.
• Wet filter used for dry pickup: A damp filter clogs fast and is hard to clean.
• Float shutoff activated (wet pickup): When the drum fills, the float rises and suction stops.

Quick fix checklist for model 113177110

1. Unplug the vacuum.
2. Check the hose for blockage: Remove the hose and clear debris end-to-end. If your hose is cracked, kinked, or collapsing, replace it with the exact compatible wet/dry vacuum hose, 1-1/4-in x 6-ft 551013109.
3. Inspect the filter and retainer band: Make sure the filter fully covers the filter cage and the retainer band is snug with no gaps.
4. Confirm the latches are fully engaged: Reseat the power head on the dust drum and latch both sides evenly.
5. For wet pickup: Empty the drum if suction stops suddenly; the float may have shut off airflow.

Symptoms to cause guide

What you notice	Likely cause	What to do
Weak suction, still runs	Filter clogged	Clean or replace filter; reinstall correctly
Sudden suction stop during wet pickup	Float raised	Turn off, unplug, empty drum
Whistling or suction varies when you move the lid	Air leak	Reseat power head; latch evenly
No suction at nozzle but strong at port	Hose/nozzle clog	Clear hose/nozzle obstruction

Why it matters

Low suction is almost always an airflow problem. Fixing the restriction or leak restores performance and helps protect the motor from running at higher pitch and reduced cooling airflow.
