Metabo HPT RP18DAQ4 (Green, 1.6 Gallon)

What batteries work with this vacuum?

The RP18DAQ4 accepts any Metabo HPT 18V battery or the higher capacity 18V/36V MultiVolt batteries. Battery capacity determines runtime - a 6.0Ah battery provides approximately 4-5 hours of continuous use in eco mode, whilst an 8.0Ah MultiVolt battery extends this to around 8 hours. The vacuum automatically adjusts power delivery based on the battery type connected.

How does the PressClean filter system work?

The PressClean button activates a reverse airflow system that blows accumulated dust off the HEPA filter surface using negative pressure. This happens whilst the vacuum is running - simply press the button for 2-3 seconds and the filter clears automatically. This maintains suction power without stopping work to manually clean or replace the filter, significantly improving productivity during extended cleaning sessions.

Can I use this for both wet and dry cleaning?

Yes, the vacuum handles both wet spills and dry debris without requiring filter changes or special setup. For dry materials, use with or without the included dust bag depending on particle size. For wet cleanup, remove the dust bag and paper filter elements, leaving only the foam pre-filter in place. The 1.6 gallon tank capacity handles most workshop spills effectively.

What's the difference between eco and boost modes?

Eco mode reduces motor speed to extend battery runtime whilst maintaining adequate suction for light debris and general cleaning. Boost mode runs the motor at full power, delivering maximum 74 CFM airflow for heavy debris, wet materials or fine dust extraction. The difference in suction is noticeable - boost mode provides approximately 40% more airflow but reduces battery life by roughly half.

Are replacement filters readily available?

HEPA filters are available under part number #380954, though they can be expensive. Many users report that filters for the identically-manufactured Flex 24V vacuum work perfectly and cost significantly less. The vacuum also operates effectively without dust bags for general workshop cleanup, reducing ongoing consumable costs whilst maintaining good performance.

How portable is this vacuum for job site use?

At 4.08kg without battery, it's genuinely portable for professional use. The integrated shoulder strap distributes weight evenly for comfortable carrying, whilst the ergonomic top handle provides secure grip. All accessories store directly on the vacuum body, creating one compact unit. The 8ft hose provides good reach without constantly moving the main unit, particularly useful in vehicles or confined spaces.

What accessories come included with the vacuum?

The complete kit includes the vacuum body, Class L HEPA filter, dust collection bag, 8ft stretchable hose, extension pipes, crevice tool, floor nozzle, shoulder strap and integrated accessory storage clips. Everything needed for immediate use except the battery. The accessories are well-made with metal components on key parts and the storage system keeps everything organised and accessible.

How does suction compare to mains-powered shop vacuums?

Whilst not matching large corded shop vacuums for raw power, the 74 CFM airflow handles most workshop tasks effectively. It excels at fine dust collection, vehicle cleaning and general debris pickup. The cordless convenience often outweighs the power difference, particularly for quick cleanups or working in areas without mains power. For heavy-duty continuous use, a corded vacuum remains more suitable.
