FAQ Section
Do electric scrubbers really work?
Yes, they work by providing consistent mechanical agitation that is faster and more frequent than human hand-scrubbing. They are most effective when paired with the correct cleaning chemical.

For users with mobility issues, back pain, or large areas to clean, they are worth the investment. For small, single-room apartments, a manual brush may be more space-efficient.
Can they clean grout effectively?
They can clean surface stains and fresh mildew from grout. However, if the grout is permanently stained or needs “raking” out, a power scrubber will not be a substitute for regrouting.
How long does the battery last?
On a standard 2.0Ah 18V battery, the P4500 typically runs for 30 to 60 minutes depending on the pressure applied. Higher capacity batteries (4.0Ah+) can extend this significantly.
