Competitive Battery Machines
On machines with replaceable batteries, the batteries do not last more than an hour or two on hard-to-remove flooring. They have a quick change system for changing the two battery packs but most owners report needing several battery pack sets to keep the machine running during a normal work day. Battery packs are $1,500+
The small battery and all-day battery machines are very slow, 100 ft./min maximum.
Some competetive machines are a narrow 24” in width and top heavy. There are several reports of them tipping over when loading and unloading.
Because of their high-pressure hydraulic system, competitive machines operate in a herky-jerky fashion. At first they don’t respond to controls and then they suddenly lurch forward about 6”. This is particularly problematic when trying to negotiate confined areas. In the Case Study described below, this would put them through the glass wall.
