I love the big boss but could definitely be more durable! In one year the hose sprung a leak near the handle, charging light broke, plug receptor for charging broke and couldn't recharge, switch shouted out too . About $200 in parts and a bitch to replace. Needs a longer and more durable hose, clear tank to see liquid, switch near handle to protect it and not require constant bending, charging indicator, no charging position on the switch, bigger pneumatic wheels for bringing up stairs, a charger that doesn't break with a years normal wear and tear, a hose that is longer and doesn't kink when you walk farther than 4 feet! I can't live without my big boss and don't want to go back to an omni or multi. I would pay more for equipment that lasts, maybe cimex will make a sprayer!!
