can only agree with the positive reviews. long I was skeptical ... but due to back problems I've tried it but ordered ..., unpacked, and tried'm .......... absolutely loved it! would never have thought possible such problems even greatest window as "symptom-free" to get so clean! and this with so vanishingly low water consumption, only a small squirt of dishwashing detergent and one has radiant windows than ever! This cleaner is worth every penny !!!
