can you upgrade any prochem machines with any powerhead attachments like you can add pw to karcher?

[robert meldrum]

You could add the Extracta powerbrush to any portable but only requires about 120 "ish " psi. They come up on here occasionally.

would pw20 or pw30 from karcher work if i change the plugs?

[Ian Gourlay]

Should do looks PW20 looks the same as Ashbys  but parts are expensive.

A new belt on Karcher Web Site is £57

By the sounds of it you have one alrady and have tried to replace bearings.

I was told bearing come as part of  replacement  brush

[robert meldrum]

There's a big difference in the Extracta and little Karcher units. The Extracta is about 4 times the weight and of a very solid construction. Also the Extracta brush action is a forward / backward motion rather than spinning.

got 2 bearings out and replaced them with 2 new ones, cost me £10. New brush is 150
