Setup
Follow these steps for initial assembly and preparation for use:
- Unpacking and Component Identification: Carefully remove all components from the packaging. Lay them out to identify each part. Refer to the "Package Contents" section to ensure all items are present.

- Attaching the Float Assembly and Filter:
The float assembly and dry use filter are crucial for proper operation, especially during wet vacuuming. The float prevents water from reaching the motor when the tank is full.
- Locate the float assembly (often a cage-like structure) and the dry use filter (a pleated paper filter).
- If not already installed, attach the float assembly to the underside of the vacuum's lid. It typically twists or snaps into place.
- Slide the dry use filter over the float assembly. Ensure it fits snugly and covers the float completely. This filter separates dirt and debris from the air, collecting it in the tank.

- Securing the Lid: Place the lid back onto the vacuum tank. Engage the locking latches on both sides to securely fasten the lid to the bucket. Ensure a tight seal for optimal suction.
- Connecting the Hose: Insert one end of the flexible hose into the intake port on the vacuum. Twist or push firmly until it locks into place.

- Attaching Accessories: Attach the desired accessory (crevice tool, floor nozzle, or extension wand) to the open end of the hose. For extended reach, connect the extension wand(s) between the hose and the desired nozzle.
- Battery Installation: Insert a fully charged RYOBI ONE+ 18V battery into the battery port on the vacuum's lid. Ensure it clicks into place.
Operating Instructions
This vacuum is designed for both wet and dry applications. Always ensure the correct filter is installed for the task.
Dry Vacuuming
- Ensure the dry use filter is properly installed over the float assembly.
- Select the appropriate accessory for the surface you are cleaning (e.g., floor nozzle for large areas, crevice tool for tight spaces).
- Turn on the vacuum using the power switch located on the lid.
- Move the nozzle over the dry debris to be collected.
Wet Vacuuming
- For wet vacuuming, the dry use filter should be removed. A foam filter (sold separately or included with some models) is typically used for wet applications to protect the motor from liquids. If no foam filter is available, ensure the float assembly is clear and functioning.
- Turn on the vacuum.
- Move the nozzle over the liquid spill. The float assembly will rise and shut off suction when the tank is full to prevent overflow.
- Once the tank is full or the task is complete, turn off the vacuum and empty the tank.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your vacuum.
- Emptying the Tank:
After each use, especially after wet vacuuming, empty the tank. Disconnect the battery, unlatch the lid, and carefully lift it off. Dispose of collected debris or liquids. The removable top design facilitates quick and mess-free emptying.
- Cleaning the Filter:
For dry use filters, tap off loose debris or brush it clean. For heavily soiled filters, wash with mild soap and water, rinse thoroughly, and allow to air dry completely before reinstallation. Never use a wet filter for dry vacuuming.
- Cleaning the Tank and Accessories:
Wipe down the inside of the tank with a damp cloth. Clean accessories as needed to prevent clogs and maintain suction.
- Storage:
Store the vacuum in a dry, indoor area. Utilize the onboard accessory storage and hose dock for a simple and compact storage solution.
