Review on CLEANZOID All Purpose Drill Brush Set - 3 Attachment Kit Pack for Effortless Cleaning of Grout, Tiles, Sinks, Bathtub, Bathroom, and Kitchen Surfaces by Kristen Szabo

I have used the 4 inch brush twice, once on horse blankets (e.g. very large windcheaters). It worked well. But today I used it to remove dog hair from car carpets. It worked great at first, but the shaft either broke or became disconnected so it spins without powering the brush. Now it's useless. Update: Cleanzoid contacted me about my review and gave me the choice of replacing the kit or refunding it. I got curious so I took a spare. I've used the large brush multiple times, including in the same dog hair/car carpet scenario, and it's held up great. This was well outside of Revain's 30-day return window, so kudos for proactive customer service. Raised the rating to 4 stars.
