Cleaning — FAQ
Can electric scrubbers handle pressure washer-level cleaning on patios?
No—they complement pressure washers but don't replace them. Scrubbers excel at agitating cleaners into porous surfaces and removing surface grime. For deep-set stains, use both: scrub first, then pressure wash.
How long do batteries last on large patio jobs?
Quality 4000mAh batteries run 90-120 minutes. A 1000 sq ft concrete patio typically needs 45-60 minutes. Dual-battery kits let you swap without stopping, effectively providing unlimited runtime.
Will these damage decorative stamped concrete or pavers?
Use soft-bristle or polishing pads on decorative surfaces. Avoid metal brushes and high-RPM settings (over 1000) on sealed or painted concrete. Test in an inconspicuous area first.
Are cordless scrubbers powerful enough for moss and algae?
Yes—20V models with stiff brushes remove moss effectively. Pre-treat with patio cleaner, let sit 10 minutes, then scrub. For heavy growth, make two passes with a wire brush attachment.
Can I use patio cleaning chemicals with these scrubbers?
Most units handle pH-neutral and alkaline cleaners. Avoid harsh acids (muriatic) and solvents that degrade plastic housings. Always rinse the unit after chemical use to prevent seal deterioration.
What's the difference between RPM and torque for patio cleaning?
RPM controls speed; torque maintains that speed under load. High RPM (1200+) cleans faster, but high torque prevents stalling on rough concrete. Best patio units balance both: 800-1000 RPM with 20V+ motors.
