Buying Guide

Choose by tank material

Confirm whether the scraper is rated for glass, acrylic, or both — some magnetic cleaners include plastic blades for acrylic to avoid scratching

Check magnetic strength

Stronger magnets improve reach on thicker glass and reduce slipping, important for larger tanks or frequent use

Look for replaceable blades or pads

Models with replaceable scrapers or pads extend product life and let you swap in softer materials for acrylic

Consider float or safety features

Floating or tethered inner magnets prevent drops into the tank if separation occurs and make retrieval easier

Evaluate ergonomics and handle design

Comfortable grips and swivel heads reduce wrist strain and improve control for reaching corners and curved glass
