  1. Ludu C Monster Chem

    Sprayers worked amazing at Legoland! We did 250 rooms, lobby, and hallways. Used them today on a full charge and never needed to charge it! I think 3-4 hours straight and still going. Love the battery on this thing! -Ludo C Monster chem

  2. Dwight S Fresh Start Carpet Cleaning

    Best cordless sprayer I’ve ever had. I use it 5 days a week, and I mean a lot! The battery holds a long charge. I recharge it about every 3 days of heavy use. Ive had it for around 10 months using it daily and never had it break down. It is truly a great sprayer hands-down, in the real world

  3. Rodney R Tuff carpet cleaning

    Its the best sprayer for spotting urine, or pre spraying furniture upholstery, tile and grout. I love it and use it on every job. Yours is the best for pretreating. Five starts. Being able to charge it in the van between jobs is a definite plus. Its super lightweight. We love it. its the best on the market.
