Cleaning — FAQ
Can electric floor scrubbers damage kitchen tile grout?
Only if used improperly. Avoid metal brushes; use nylon grout attachments at medium speed. Our tests showed 800 RPM is safe for cement-based grout when you keep the brush moving—never hold it stationary.
How do I clean the brush heads after use?
Rinse under hot water immediately after cleaning greasy messes. For deep sanitization, soak in a 1:10 bleach solution for 10 minutes. Most nylon heads are dishwasher-safe on the top rack.
Are these scrubbers safe for hardwood kitchen floors?
Yes, if the wood is sealed. Use the soft flat mop attachment, lowest speed setting, and minimal water. The qimedo M3's spray control excels here. Never use on unsealed or waxed wood.
What's the realistic battery life difference between 2500mAh and 6000mAh?
2500mAh runs 40-50 minutes; 6000mAh delivers 90-120 minutes. For kitchens under 150 sq ft, 2500mAh suffices. Larger kitchens or whole-house cleaning justify the larger battery.
Can I use my own cleaning solution in the spray tank?
Most manufacturers approve mild detergents. Avoid bleach, ammonia, or abrasive chemicals—they can degrade tank seals and void warranties. Always rinse the tank with water after use.
How long do brush heads last before replacement?
With weekly use, nylon heads last 12-18 months. Heavy daily use shortens lifespan to 6-9 months. Rotate heads between tasks to distribute wear. Replacement packs cost $15-25 for multi-head sets.
