Cleaning โ FAQ
Can cordless vacuums handle fine concrete dust?
Yes, but only models with sealed HEPA filtration and high KPa ratings. Standard vacuums clog quickly and leak dust. Look for brushless motors and 55KPa+ suction for effective concrete dust management.
What suction power do I need for concrete floors?
Sealed concrete needs 40KPa minimum. Raw, porous, or textured concrete requires 55KPa to 60KPa to extract embedded grit. Higher power prevents multiple passes over the same area.
Are HEPA filters necessary for concrete cleaning?
Absolutely. Concrete dust contains respirable silica that damages lungs. HEPA filters capture 99.97% of these particles. Non-HEPA vacuums exhaust dust back into your breathing zone.
Will vacuum wheels scratch polished concrete?
Quality vacuums use soft rubber wheels. Avoid plastic casters. Test by dragging the vacuum on a sample piece. Many models have brushroll-off modes that use suction only, eliminating brush contact.
How long should the battery last for garage cleaning?
A 2-car garage needs 45-60 minutes. Choose vacuums with 65+ minute runtime ratings. Contractors should prioritize removable batteries to swap and continue working without 3-hour charging breaks.
Can these vacuums handle wet concrete slurry?
No. All cordless vacuums listed are for dry debris only. Wet/dry shop vacuums are required for slurry. Using a standard vacuum on wet messes destroys the motor and creates electrical hazards.
