Well Done Unger!!!

by J Robinson

1-2 minutes and you can change out the filters robust parts were you need them. solid Rubber tires, the cart is well made and will not rust.
Unger Hydro Cart is the Best DI cart for the money and i use this cart every day for 5-8 hrs. all year long...
its a good idea to have a spare set of filters in your vehicle, I usually change out the filters when i see a reading of 5 ppm and slowly climbing.
buy metal quick connects etc. were possible plastic parts will not hold up. this machine works in cold weather i have used it in 35-40 degree weather. in the hot summer heat its a good idea to shade the machine under a tree etc. wherever shade is possible while working for extended periods of time.

Excellent Quality Window Cleaning Cart!

by Super Man gets a job

Excellent reliability, TDS meter built in, filter change 5 minutes max.
I have been cleaning windows for over 20 years and have owned many water carts this one surprised me as to how efficient it works over all the cost is nominal. solid rubber tires the cart is well built! Best money you can put to use for your window cleaning needs!!! And no I'm not paid to say that! I'm tough as nails on products and demand the best performance possible and Ungers cart has not disappointed over 4 years of daily use.
