Disclosed herein is a bucket caddy comprising a U-shaped frame, a plurality of caster wheels, two vertical members and two vertical members. The U-shaped frame comprising a first horizontal member, a second horizontal member, and a third horizontal member, wherein a first end of the first horizontal member is connected to a first end of the third horizontal member and a first end of the second horizontal member is connected to a second end of the third horizontal member. The plurality of caster wheels supports the U-shaped frame. The two vertical members comprising a first vertical member and a second vertical member, wherein the lower end of each the first vertical member and the second vertical member is attached to the first horizontal member and the second horizontal member respectively. The bucket holder is secured to the two vertical members via two removable pivots and two cotter pins.

An extendable strut assembly comprises a nested series of square or rectangular beams, the centermost of which may be a solid bar and all others are hollow sections. Glide strips of predetermined thicknesses take up the clearances between the beams and can be affixed to the beams by adhesive, so that beam surfaces run smoothly on the glide strips and the strut assembly can be extended and retracted with ease.
