Okay, so if you clean windows professionally or even just at home, this Unger ErgoTec Ninja bucket-on-a-belt thing is super handy.

It's basically a small 0.5-liter water pouch that clips right onto your belt, so you always have water with you without carrying a big bucket.

It has quivers (holders) for up to two wipers and a squeegee up to 45 cm, plus a spot for a safety scraper.

That means all your tools are within easy reach, leaving both hands free—super useful when you're on a ladder or working in tight spaces.

The clip closure lets you take it off your belt with one hand, no need to unbuckle anything.

It's designed for both left- and right-handed folks and can even attach to a ladder.

Seriously, it makes interior cleaning, detail work, or any task where you need quick access to water and tools way more efficient.

A real time-saver for cleaners.
