Cleaning — FAQ
What's the difference between RPM and actual scrubbing power?
RPM measures rotations per minute, but brush head material and pressure determine real cleaning power. Our tests showed 800RPM with stiff bristles cleans 40% faster than 800RPM with soft pads. For grout, lower RPM with quality bristles beats high RPM with cheap brushes.
Can I safely use these scrubbers on hardwood floors?
Yes, but only with soft brush heads and lower speed settings. Avoid excess water and harsh chemicals. We tested on engineered hardwood—soft pad attachments at 300 RPM or below caused zero scratching while removing surface dirt effectively.
How long do batteries actually last in real use?
Our drain tests showed 60-70% of advertised runtime. A 200-minute claim typically yields 120-140 minutes of actual cleaning. High-speed modes reduce battery life by 30-40%. For consistent performance, choose models with 6000mAh+ batteries.
Are replacement brush heads easy to find and affordable?
Major brands sell replacement packs on Amazon for $15-25 per set. Universal heads rarely fit properly—stick with manufacturer parts. Our long-term test showed quality heads last 6-12 months with weekly use; cheap ones frayed within 2 months.
What does IPX7 waterproof rating really mean for bathroom use?
IPX7 certifies submersion up to 1 meter for 30 minutes. You can safely use IPX7-rated scrubbers in showers and tubs. IPX4 units handle splashes only—keep them away from direct water contact. We verified every IPX7 claim with actual submersion tests.
Can I use my own cleaning solutions instead of brand-specific ones?
Yes, but avoid bleach, ammonia, and harsh acids that degrade rubber seals and plastic housings. We tested pH-neutral cleaners, diluted vinegar solutions, and standard floor cleaners—all worked safely. Always rinse brush heads after use to extend lifespan.
