4. Product Overview
The BuTure VAC JR400 is engineered for powerful and convenient cleaning. Familiarize yourself with its key components and features.
4.1 Powerful Suction
Equipped with a 450W brushless motor, the JR400 delivers an unprecedented 38,000Pa of suction power, making it highly effective for various cleaning tasks, from fine dust to larger debris and pet hair.

4.2 Detachable Battery
The vacuum features a detachable 7*2200mAh Lithium-Ion battery, providing up to 55 minutes of runtime on low suction mode (15 minutes on high suction). The battery can be easily removed for charging or replacement, and fully charges in 4-5 hours.

4.3 Smart Touch Display
An intuitive LED touch screen allows for easy adjustment of 5 suction power levels. The display also provides real-time information on battery level, current suction level, and alerts for brush roller tangles or dust sensor blockages.

4.4 Large Capacity Dust Cup & Multi-Filtration System
The 1.5L dust cup minimizes the frequency of emptying, holding more dirt and pet hair. A 5-stage filtration system, including HEPA filters, effectively isolates dust particles, protects the motor, and releases fresh air.

4.5 Upgraded 2-in-1 Tangle-free Roller
The electric floor brush features an integrated hard and soft bristle roller, designed to work effectively on both carpets and hard floors without tangling hair. This eliminates the need to switch brushes for different surfaces.

4.6 Versatile Cleaning Modes
The JR400 easily converts from a stick vacuum to a handheld unit, and its adjustable tube (40-64cm) and various accessories allow for cleaning a wide range of surfaces and hard-to-reach areas, including ceilings, upholstery, and car interiors.

- Assemble the Main Unit:
- Insert the adjustable tube into the main motor body until it clicks securely into place.
- Attach the electric floor brush to the other end of the adjustable tube, ensuring it clicks into place.
- Alternatively, for handheld use, attach desired accessories (round brush, crevice brush) directly to the main motor body.

6. Operating Instructions
Learn how to effectively use your BuTure VAC Cordless Vacuum Cleaner.

- Adjust Suction Power: Use the touch display to adjust the suction level. Slide the speed bar on the screen to select one of the 5 available suction power settings.

- For floors and carpets, use the electric floor brush. The integrated roller is suitable for both.
- For tight spaces, corners, or crevices, attach the crevice brush directly to the main unit or the adjustable tube.
- For upholstery, curtains, or delicate surfaces, use the round brush.
- Monitoring Display: Pay attention to the smart touch display for real-time information on battery status, current suction mode, and any alerts such as brush roller tangles or dust sensor blockages.
- Emptying the Dust Cup: When the dust cup is full, or after each use, empty it by pressing the one-touch release button located on the dust cup. Dispose of debris into a waste bin.
7. Maintenance
Regular maintenance ensures your vacuum cleaner operates efficiently and extends its lifespan.
7.1 Emptying and Cleaning the Dust Cup
- Empty the 1.5L dust cup after each use or when it reaches the MAX fill line.
- To clean, detach the dust cup from the main unit. You can rinse the dust cup with water if necessary, but ensure it is completely dry before reattaching.
7.2 Cleaning Filters
The vacuum features a 5-stage filtration system. Regular cleaning of filters is crucial for maintaining suction power.
- HEPA Filter: The HEPA filter should be cleaned regularly, ideally after every 3-5 uses, or when suction power decreases. Remove the HEPA filter from the dust cup assembly. Tap it gently to remove loose dust. For a deeper clean, rinse it under running water. Ensure the HEPA filter is completely dry (allow 24-48 hours) before reinstalling. Do not use the vacuum with a wet filter.
- Sponge Filter & Stainless Steel Filter: These filters can also be rinsed with water. Ensure they are completely dry before reassembly.
- The product includes a replacement HEPA filter for convenience.
7.3 Cleaning the Brush Roller
- Periodically check the electric floor brush roller for tangled hair or debris.
- To remove the roller, follow the instructions in the manual for your specific brush head. Use the small cleaning tool provided to cut and remove any tangled hair or fibers.
- Ensure the roller is free of obstructions for optimal performance.
